On May 27, the Wenzhou Oujiang Beikou Bridge, which was built by CCCC Second Harbor Bureau, was officially opened to traffic, marking the opening of the Yongguan Expressway, the major artery along the coast of Zhejiang, Fujian and Guangdong. Facing the world's first three-tower, four-span, double-layer steel truss girder suspension bridge, the world's first high-rigidity concrete mid-tower in multiple towers and continuous spans, and the world's first super-large caisson in deep soft soil in a strong tidal estuary, it has three world-class The first bridge, Erhang people bravely climbed the peak of technology, down-to-earth, concerted efforts, and played one after another breathtaking labor hymn at the mouth of the Oujiang River.
The drums of war are thundering, but the brave are fearless. Because they dare to make breakthroughs, they are striving for progress. They use their actions to compose a touching story of Chinese bridges, making the dream of "Chinese bridges built by Erhang" into reality, and playing the strongest voice of a transportation power country. . The "Great Power Project" column will present the stories behind the construction of the Beikou Bridge.
Some people regard building bridges as a kind of belief, and Zhang Ping is the most typical one.
Like most builders born in the 1980s, Zhang Ping has dark and rough skin, and his eyes are often bloodshot. He wears a safety helmet, overalls, and a life jacket around his neck as he rushes around the construction site.
Zhang Ping is different from most builders. He can have many labels - the first person of the suspension bridge of the Second Company of CCCC Second Navigation Bureau/production manager/doer/big speaker/person who finds faults/photographer/walks the most The people, to name a few, look like a "slash boy".
So, who is Zhang Ping? Searching for the user "road builder" on Douyin, there are at least hundreds of results. Zhang Ping is one of them. The picture shows him standing on the bridge deck of the Jinsha River Bridge opening to traffic. The red gate-shaped bridge tower behind is surrounded by clouds and mist, and the green hills are faintly visible in the distance.
This may be the identity closest to him, an ordinary and ordinary bridge builder.
In the past 18 years, from Jiangsu Taizhou Yangtze River Bridge, Harbin Yangmingtan Bridge, Zhejiang Zhoushan Second Xiaogan Bridge, Yunnan Jin'an Jinsha River Bridge to today's Wenzhou Oujiang Beikou Bridge, the transcripts of 5 suspension bridges, the more experience , Zhang Ping, who was born in 1981, has gradually become clearer and clearer about his goal - to be a serious and responsible road builder.
Conscientious and responsible, simple words, Zhang Ping has been practicing for 18 years in his work, and will be longer. "Every detail has to be figured out," he said.
Open time
With the sound of "Biu", the colorful smoke rushed into the sky and lingered under the main tower of the Beikou Bridge. In less than 2 minutes, the colorful smoke seemed to be caught by the invisible hand of the wind, and turned from a column shape into a cotton ball. After passing the white bridge tower and the blue bridge main cable, it gradually disappeared into the scorching sun, blue sky and white clouds.
On May 27th, Zhang Ping, currently the deputy manager of the fourth bid project department of the Beikou Bridge of the Second Aviation Administration of CCCC, was in the duty room of the Jiangbian Steel Trestle, waiting for an interview on the Douyin live broadcast room of the Second Aviation Administration of China Communications. Looking up from the window, I saw this scene of the opening ceremony on the bridge deck.
An owner representative who participated in the opening ceremony on the spot shared a 15-second live sound video in the WeChat group, which is exactly this moment. Zhang Ping habitually saves the video on his mobile phone and forwards it to the "steel beam installation work group", which used to be his active online workplace every day.
During the waiting period, sitting on the white plastic bench, he read news on his mobile phone from time to time, and chatted with the other three who were also waiting. cotton.
During the brief conversation, he had already rolled the trousers of his left leg over his knee to his thigh. "Sizz, sizzle, sizzle", 3 pieces of plaster with white on the front and black on the back were torn off. Those three plasters had wrapped his entire knee for nearly 12 hours. Afterwards, he tore off the two plasters covering the knee of his right leg one after another, each of which was about one-third the size of an A4 paper.
"It's swollen!" The people present looked at his right leg, which was swollen like a steamed bun that had just come out of the steamer, slightly pinkish. Due to walking too much at the site every day, such a disease started to show signs of the Jinsha River Bridge. When the Beikou Bridge was completed, he had undergone a minimally invasive operation on his knee, and had been treated with a combination of Chinese and Western medicines. For some time, he had been using plaster to relieve the pain in his knee.
Recently, his knee has started to swell again, it's a pain from the inside out. "Before, when it was really serious, the pain was like a needle stick." After the traffic opened, he planned to go to the hospital for a re-examination.
However, at the moment when the traffic opened, he watched the live broadcast of Douyin and seemed to have forgotten the pain in his knee.
At 10 o'clock, he opened the Douyin live broadcast on time, and he was smiling. After he saw the anchor, the first sentence came out: "Guy, why didn't you shave when you appeared on the scene?" I wrote a message and posted three consecutively - "The bridge builders are too good", "CCCC Erhang Zanzan (two emoticons)", "The guy is so handsome". He pursed his lips and smiled, unable to restrain his joy.
Ten minutes later, about half an hour before his appearance, he didn't stop for a moment. When I walked out of the room, I naturally merged into the banner hanging team, with the draft of the live broadcast in my trouser pocket.
"The word is facing the outside, the word is facing the outside! This way the live broadcast can be filmed!"
"It's higher here."
"Pull down a little over there."
...
After the two sides were fixed, he fixed the middle with iron wire, looked at it, and adjusted it several times. Then, he picked up another banner and walked straight to the direction of the trestle leading to the main tower. Ten minutes later, the two banners were hung.
When it was time to appear on the scene, he also stopped, and instantly switched to the state of preparing for the live broadcast.
During the nearly ten-minute outbound interview, he was a little nervous at first. When he talked about the hoisting of steel beams, the more he talked, the more he entered the state, and his tone rose from time to time. When he speaks, he bites the words back, sometimes swallowing a certain word, and there will be an accent every few words. It seems like he is lightly biting a small piece of apple peel, but he is so angry that he can actually bite it off in one bite. a third of an apple.
"Since the brothers went to the construction site with me, I will bring them up safely."
"Our whole bridge has a total of 110 steel beams, and all of them were finally hoisted safely and safely."
...
In the end, his time to appear on the screen is over.
Engineers become "photographers"
Zhang Ping, who studied civil engineering, doesn't have many hobbies. He doesn't even smoke cigarettes. Photography is something he has been doing from beginning to end. It was precisely because of the needs of the bridge construction that he fell in love with photography.
In June 2007, Zhang Ping was transferred from the Hangzhou City Balcony Project Department to the Taizhou Yangtze River Bridge Project Department and started the construction of the first suspension bridge in his life.
The Taizhou Yangtze River Bridge is not considered a veteran bridge in the CCCC Second Aviation Bureau, but it is definitely a "brother" of a suspension bridge worth mentioning. Its main bridge across the river adopts a 2×1080-meter three-tower two-span suspension bridge. Its construction has created the world's first kilometer-level multi-tower continuous-span suspension bridge.
The industry status of this bridge cannot be ignored, and more importantly, it also occupies an absolute position in the second company - the first suspension bridge superstructure.
At that time, the second company dispatched the elite soldiers who participated in the construction of the first cable-stayed bridge with a main span of over 1,000 meters, the Sutong Yangtze River Highway Bridge, and started a new journey of construction of the superstructure of the suspension bridge.
However, since it is the first time to participate in the construction of the superstructure of the suspension bridge, the understanding of the core details of the drawings is not thorough, which is equivalent to knowing only one of them but not the mystery behind it. Such an approach is mechanical. Therefore, if you want to be self-reliant, you have to spend more time studying. How to learn has become the key. Zhang Ping and the others used a magic weapon - photographing them with a camera and learning them and drawing them according to the size.
During the daytime working hours, the construction team carefully completes each construction process on site according to the requirements. When it was time to rest, when no one on the site was interfering with the construction, Zhang Ping would take the card machine he bought for 2,000 yuan to the site, measure the size, take photos of every detail, and then print out the photos. After repeated comparison and calculation, the drawings were finally drawn one by one with CAD.
It took nearly 10 months for Zhang Ping to record all the content in this way, and formed a drawing, from being given by others to being self-sufficient, from passive to active, which also helped the team. Successfully took root in the construction of the suspension bridge market and laid the foundation.
Recording the scene with a camera has thus become an important work habit for him, and has gradually become a personal hobby.
In 2011, on the Yangmingtan Bridge in Harbin, faced with the alpine construction weather of minus 20 degrees. Once, Zhang Ping issued a rectification notice to the collaboration team, with dozens of items on a whole page. Due to the high safety risk when lifting large components such as cable saddles, he will carefully check each nut.
Old Yang, who is in his 50s, is a top student at Tongji University. Seeing this news, he sued the project manager's office directly. Confrontation on the spot was inevitable. Zhang Ping, who was 30 years old at the time, was not afraid. He took out his camera, flipped through the pictures, and checked each rectification content. This kind of reason and evidence makes the other party only give up and admire it.
About three or four years later, at the Second Bridge of Xiaogan in Zhejiang, the two met again. The retired old Yang repeatedly praised: "This guy is not bad."
More than ten years later, his photographic equipment has been updated all the time. He has bought two digital cameras and a handheld video camera successively. At Beikou Bridge, he is also equipped with a Gopro motion camera. Most of the time now, he shoots with his mobile phone, which is convenient and efficient.
"Too many photos." Zhang Ping left behind a treasure trove. Photos from more than ten years ago can be found on his hard drive, online disk or mobile phone. Except for a few photos of family members, most of them are from various projects. Video of the scene. "There is a 1T hard drive. If it is broken, there will be no pictures."
Turning on his computer is like picking up shellfish in the sea. During the interview, while talking, he would turn out a photo, and through each picture and each video, he could recall the details of the story during the construction.
"I took 80% of the pictures I sent to the circle of friends." When Zhang Ping said this, he was a civil engineer and a photographer, with a proud and confident face.
"Long" on site
Every time he goes to the scene, the equipment that Zhang Ping carries is a little different.
He wears a pair of combat boots every day on the construction site and in addition to the necessary overalls, hard hat, and life jacket, he also has two special companions - a camouflage fanny pack and an army green "big horn". Inside the pocket, a wrench and a vise are necessary, and if it is summer, heatstroke prevention and cooling drugs will also be placed.
Especially unique is the "big speaker", which is about 50 to 60 centimeters in height, equivalent to the size of the radio speaker installed at the entrance of the village. In the project department office by the riverside, the voice of him directing the construction work can be heard from the loudspeaker.
"It's covered with knock marks." When he picked up the loudspeaker from the coffee table and put it down, he seemed to see himself at the scene.
Zhang Ping's equipment
He will also prepare 2 one-liter water cups, one is a transparent plastic cup, the other is a stainless steel thermos cup, a cup of warm water, a cup of hot water, so that he can stay on site all morning, and even for a day when the weather is cold .
"This whole set of equipment adds up to 15 or 6 kilograms." Every day, he wears such "long" clothes on the site, and carries the mission of "taking himself as the last level of on-site construction". He will go to the scene to check every corner, where the iron wire is loose, as long as he can solve it at the first time, he will not let it go.
Zhang Ping made full use of the work habit of taking pictures on the Beikou Bridge, and gradually became a "person who likes to find faults".
Many times, you will see him taking pictures on the spot with his mobile phone or camera. He will mark the problems he has taken with the retouching software, and write down the matters that need to be rectified or paid attention to. Full red and yellow circles or lines, as well as pictures with text, will appear one by one in the work group.
Busy is his norm. He is probably the person who walks the most in the project department. During the peak period of hoisting steel box beams, he has to go back and forth between the water and the air catwalk more than ten times a day. The catwalk of the bridge is a linear temporary construction access road that is erected under the main cable and parallel to the main cable during the construction of the suspension bridge.
The one-way catwalk of Beikou Bridge is 2,250 meters long. Zhang Ping walks while inspecting the site. One trip takes about 1 hour and 20 minutes. It takes about 3 hours to walk down the two catwalks. Walking at a height of 60 meters from the river surface is easy for him. The lowest point of the catwalk of the Jin'an Jinsha River Bridge was about 348 meters away from the river surface, and the highest point was 478 meters away from the river surface. And such a special journey, for ordinary people, it takes twice as long to complete.
"The catwalk I walked won't leave any problems." Zhang Ping said with a smile. On the surface, he is a serious person. After in-depth contact, you will find that how serious he is, how direct and forthright, and with a sense of humor, he will make that kind of short "snort" laughter, In a series, the last sound brakes suddenly and is caught off guard.
However, walking on catwalks is not friendly to builders' legs. "Like a lesbian wearing high heels, the knees will be locked, and the whole weight will be on the knees, especially when the up and down slopes are steep, and they will bounce up and down when walking on them, which hurts the knees." Zhang Ping felt deeply.
At the beginning of January 2022, after having been in pain for 2 months, he finally returned to Kunming for minimally invasive surgery to remove the fluid. Nearly 5 months later, the pinhole is still visible. Under the dual action of oral medication and topical application, he also gradually improved.
During the Spring Festival, after returning to the scene, he still maintains the habit of going to the scene every day, even though the bridge has closed and is drawing to a close. Every day, he rides an electric bike and goes to the bridge to inspect and finish the work. This trip is more than ten kilometers.
Zhang Ping still has a telescope on his desk. When he doesn’t have time to go to the site, he will look at the construction site about one kilometer away from the project department at the door of the office. Once he finds a problem, he will immediately call the site to lead the team. personnel.
"Be strict with yourself, and be stricter with others." Yang Jindong, the on-site leader of the Beikou Bridge Steel Beam Installation Collaboration Team, leaned on the sofa in Zhang Ping's office, and used Chongqing dialect to circumvent this sentence, like a tongue twister.
Worried Doers
Worrying and a little irritable is the most direct evaluation of him by colleagues. He could never let go, except for one possibility - the job was done.
There is a short video widely circulated in the Beikou Bridge Project Department. One day in August 2021, Zhang Ping and his team members were installing the spreader on the steel beam of the transport ship in the center of the river. Just when the spreader was connected to the lifting lug, there was a sudden downpour, there was no place to hide from the rain, and there was no way to stop. . I saw Zhang Ping, who was not wearing a raincoat in the video, waving a sledgehammer, banging bang, banging on the connector, and the raindrops made a mess and hit them... In the end, the 6 people will be thicker than the thigh. Giant steel truss girders connected together.
"Even the underwear was soaked through." Everyone's impression of the construction was surprisingly unanimous. "At that time, the on-site workers were unwilling to continue working."
Zhang Ping posted the video on his Douyin account with the caption: Salute to the workers. The video is also accompanied by a recording of a farewell letter from the athlete Liu Xiang when he retired: There are always peaks and valleys in life, do not lose yourself in good times, do not forget the original intention, stand the test in adversity, dare to challenge dreams, dare to do. Although not every dream can become a reality, the process of diligent pursuit will become a valuable spiritual wealth in my life.
In July, we enter the typhoon season. Wenzhou also entered a state of preparation. At that time, the hoisting work of 110 steel truss girders officially started. The largest hoisting section weighed 1,200 tons (including the spreader), and the total weight of the whole bridge steel truss girders was about 77,000 tons. This is also the time when Zhang Ping's pressure is the greatest, all steel truss beams are installed, and the typhoon season is basically over. The entire installation cycle completely coincides with the typhoon season.
The installation of steel trusses is the most important part of the construction of the superstructure of the Beikou Bridge. The 1000-ton cable-mounted crane with the largest lifting capacity in the world independently developed by the project team of CCCC Second Aviation Administration is a "great hero". Behind this, the team led by Zhang Ping is the last link behind the entire "great hero". .
The scene of the "performance" of the cooperation between the machine and the human has become a commonplace here.
The main operating area of Zhang Ping and his team is between the beam carrier in the water and the catwalk at high altitude.
The beam-carrying ship needs to be positioned in the flat tide when the water flow on the river is relatively gentle. Zhang Ping, who is wrapped in a pocket and carrying a loudspeaker, leads the construction workers up the escalator on the side of the steel truss girder, dressed in orange overalls. The 10 staff members climbed up to the top of the blue steel truss step by step. "People walk up like ants." Zhang Ping looked at the photo in the computer and said.
The team's task was to connect the spreader to the lug. The first time, it took them about 1 hour and 40 minutes. Later, it only took about 40 minutes. After the cable-mounted crane spreader firmly grasped the steel truss beam, for Zhang Ping, the next step was a long wait.
They need to communicate with the operator of the cable-mounted crane, whether the equipment is running normally and whether the lifting height is in place. At the same time, they will move to the catwalk at a high altitude. When the steel truss beam is lifted in place, they will carry out the final precise adjustment and docking work. . In the final precise adjustment, Zhang Ping was very persistent, saying that it should be kept within a few millimeters. There was a back-and-forth that didn't end until 3am. They left at 4pm the day before.
During those days, Zhang Pinghe's team also set off at 4:00 in the morning, in order to better position the ship at low tide, and also to ensure the accuracy of hoisting.
There was a little thing that surprised and worried him. In the early stage of construction of the catwalk of Beikou Bridge, Zhang Ping, as the person in charge of the site, basically received seventy or eighty or even more calls every day. One day, he suddenly received a text message, roughly saying that he was suspected of fraud, and he learned that his phone was officially restricted from calling.
"People at the scene came from all over the world, and different numbers from different places frequently dialed, so they were blocked." Speaking of this incident, he analyzed it like this.
Fortunately, the mobile phone number that was used in the Zhejiang Huzhou project has been retained. His Huzhou number and Kunming number are used alternately, so that he finally successfully avoids being blocked again.
It is precisely because of this that for a long time, his WeChat name will be followed by parentheses to note his mobile phone number, and he will also inform everyone through the circle of friends which number to use recently, so that anyone can find him at the first time. "There are so many people and so many things at the scene. If you can't contact me, it will be a big delay."
Home and Home
Zhang Ping's hometown is Solo Township, Huaping County, Yunnan Province, a place surrounded by mountains. He grew up in the mountains when he was a child. He used to dig for medicinal herbs, mushrooms and wild yams on the cliffs of the deep mountains, which is also one of the sources of income for his family. Later, he went to Inner Mongolia to study at university across most of China. In the past few years after graduation, in addition to Harbin and Lijiang, he mainly moved to Jiangsu and Zhejiang regions.
On the Taizhou Yangtze River Bridge, Zhang Ping's life ushered in an important turning point. He completed three important things in his life. The accumulation of experience in suspension bridge construction is one, marriage is the second, and the undergraduate degree is the third.
In September 2009, the main tower steel tower of Taizhou Bridge was being hoisted. He invited a photographer from the studio to take his own wedding photos on the pier not far away with the bridge as the background. That's it, the bridge is like a witness, and a new family is born.
On September 9, he held his own wedding in a hotel seven or eight kilometers away from the project department. On the wedding day, because the parents were too far away, they did not come to the scene. The project manager was the witness, and the guests present were basically colleagues from the project department.
Zhang Ping outside the computer screen watched Zhang Ping and his wife walk through the flower gate and onto the stage for more than ten years, as if they were traveling through time and space. At that time, his figure was not much different from that of now. Now he has a pair of children, the older one is in the second year of junior high school and the younger one is in kindergarten.
Zhang Ping may be someone who looks for a little romance in engineering. At the Jinsha River Bridge and Beikou Bridge, he had thought about planning catwalk weddings, but in the end, unfortunately, they were not implemented.
When it comes to the Jinsha River Bridge, it is the closest project to his home. "Building a bridge in front of my home may only be a once-in-a-lifetime opportunity." Zhang Ping said.
Jinsha River Bridge, the mountain natural conditions and environment are relatively poor, the altitude is high, and the bridge height difference is large. Wind and rain can also cause landslides, especially the Akendong Bridge is located in a valley close to 90 degrees, "even the mountaineering team is reluctant to go."
Although the construction is carried out on the cliffs surrounded by mountains, Zhang Ping has never been afraid of such a deterrence and challenge from nature, and is always the first to take the lead in rushing to the front line. Perhaps because of the construction of the bridge in front of his home, Zhang Ping seems to have found some kind of connection with the Jinsha River Bridge.
Zhang Ping, who grew up in the mountains of Yunnan, has a very strong survivability. "You can leave me in the mountains for ten days and a half months." Going across mountains and mountains to find water sources to ensure the project's domestic water and construction production.
Between the mountains and mountains, the canal seems to be inlaid on the 90-degree mountainside. Zhang Ping needs to walk for several kilometers and walk to the source. When he sees the leakage of the canal, he needs to clean up the sundries, move out the stones, and be diverted. The places need to be corrected... Zhang Ping himself does not remember how many times he has done such inspections.
However, the closest to home is the least. One time, he went home to reissue his ID card during a shift, and it was just time to see his wife and children. He ran all the way back to Kunming from the project department. Unexpectedly, he received a call as soon as he got home, because the two leading teams on duty in the project department had business needs. On a business trip, the last resort had to let him go back. After having lunch at home, he immediately went to the police station to reissue his ID card.
At that time, Zhang Ping was still wearing the white shirt on the project. Since he was not wearing it in accordance with the photography standards, at any rate, he couldn't remember where he found a coat and put it directly on the outside, so that the photo was taken. Then hurried back to the project department.
It is such a busy, unknowingly, 18 years have passed. In the past 18 years, he has spent more than two-thirds of his time in Jiangsu and Zhejiang, but no matter what, his taste has not changed much, it is still the taste of his hometown.
Zhang Ping, who has been wandering all the year round, keeps moving from one project to another. "I thought that after this project was over, I could go home and rest for a few days. After two days, I received a notice to go to the next place." I didn't have time to think about it. , he will set off again. On the other side of the house, most of the time it always appears in voice or video calls.
This is Zhang Ping, a strong Yunnan man with a height of nearly 1.8 meters, a dedicated and simple bridge builder.
On the day it was opened to traffic, in just ten minutes in the live broadcast room, he took it easy and talked about the construction of the Beikou Bridge. In the camera, he is wearing a blue safety helmet and beige long-sleeved overalls. On the right chest is a party member badge, on the left is the word "Beijing Bridge", and behind him is the Oujiang River flowing slowly; outside the camera , About 200 meters away, on the outer wall of the processing factory, there are 14 signs with white characters on a red background: Carrying forward the spirit of model workers, the spirit of labor, and the spirit of craftsmen.
Just as Zhang Ping was talking about his excitement, the wind was blowing from the side, the red sword flag with the words "China Communications Second Aviation Bureau" whistled, and the river rhythmically beat the shoal on the shore, saying "Wow, wow, wow, wow, wow, wow, wow, wow! "Wow," the sound was crisp and clear, as if giving him continuous applause.
The tide brought applause, not only to Zhang Ping, but also to all the builders.
