At 11:55 p.m. on February 5, the outdoor temperature was as low as minus 3 degrees Celsius, the yellow emergency rescue vehicle "boom boom" sounded, and three "post-90s" and "subway tunnel doctors" braved the wind and snow to set off from Hankou Zhaojiatiao. They were going to the area between Tanhualin and Peng Liuyang to repair a leak.
The young men are Hu Chentao, Liu Yang, and Shen Bo from the Emergency Maintenance Branch of China Railway 11th Bureau Urban Rail Company. In addition to dealing with major dangers, they also have to deal with daily inspections, repairs and reinforcements of main structures such as subway tunnels, stations, and viaducts to ensure the safe and stable operation of the subway.
Wu Zhihua, the manager of the company, said: "This Spring Festival, the project left more than 10 people on duty to be responsible for the emergency maintenance and disposal of the three subway lines of Line 2 and Line 16, and the people on duty are all from Wuhan or the surrounding areas." Wu Zhihua is also a "post-70s" maintenance veteran and took the lead in participating in the Spring Festival duty.
At 0:30 on February 6, a group of people arrived near Entrance C of Pengliuyang Station of the subway, and the three of them pushed a small cart and walked more than 100 meters in the snow. After the station door was opened, the three of them unloaded the materials one by one, walked to the bottom of the stairs, and placed them one by one on a piece of plaid cloth marked with the names of various materials, and counted them one by one. Only then did the Hubei ** all-media reporter see clearly what they were bringing, electric drills, lighting, grinding machines, leak plugging materials, cables, ......There are 19 types in total. "Don't underestimate this thing, it weighs more than 200 pounds, and you can carry it up and down the stairs with your hands. Feng Wei, the company's duty leader and party branch secretary, introduced that the subway has extremely strict safety requirements, how many materials and tools are brought, and how much is used, each time it must be checked one by one to ensure that none of them can be left in the section.
Luckily, the repair site is located on the track next to the station, so it is easy to transport. This piece is about 1The 5-metre-high, 20-centimeter-wide side walls were leaking water. "The tunnel structure is affected by geological conditions, surrounding construction and subway operation, which will produce common structural cracks and water leakage, which need to be dealt with in a timely manner. Hu Chentao, the person in charge of the construction, explained that every 30 centimeters or so should be drilled, the grouting needle should be buried, and a special plugging material should be injected. ”
After repeated grouting conditions, the water seepage situation gradually improved. The hour hand also crept past 2 a.m. "Next time, we will have to take a closer look and further check the effect of water seepage remediation to ensure that the disposal is completed. Liu Yang, the on-site technician, explained to reporters while observing. On the other side, Hu Chentao and Shen Bo walked in the direction of Tan Hualin with flashlights in their hands, and began another important task tonight - inspecting the tunnel structure. The two have a clear division of labor, one is responsible for observing structural diseases and assessing the health of the tunnel, and the other is responsible for recording, whether it is the grouting holes, bolt holes, joints, or drainage ditches of the tunnel segments. "Water stains can penetrate through them, so we need to be very careful. Hu Chentao suddenly stopped in front of a water stain oozing from a seam. "If it's dry, we don't care, if there is a drip in the later stage, we have to repair it, and even pass through the thick segment and plug it behind the segment wall. Hu Chentao introduced that in addition to such minor repairs and small repairs to repair leakage, sometimes major surgery is also required for the tunnel, such as repairing and reinforcing the deformed segments.
At 3 a.m., after all the work, the three began to pack up and count the materials and tools. "Small parts such as wrenches, drills, nails, etc., are easy to get lost. A pack of 50 nails, 5 were used, 45 were left, 5 drills, 5 were brought back. "The young men have a clear division of labor, and Hu Chentao is responsible for counting and verifying the items. Liu Yang and Shen Bo returned to the track to check for missing items.
Preparations began at 11 o'clock in the evening and returned to the base dormitory at 4 a.m. This night shift wasn't long, but the lads missed out on the best time to sleep. When carrying the materials, the reporter helped carry a bucket of 40 pounds of materials up the stairs and gasped for breath. Loading, unloading, and moving, they repeat this process six times a night.
Home is so close, on Chinese New Year's Eve, can you take the time to have a reunion dinner with your family and watch the Spring Festival Gala? Before saying goodbye, the reporter asked. "Although home is close at hand, we must stick to our posts, and the project department has also prepared a sumptuous Chinese New Year's Eve dinner for us, so that we can reunite thousands of families, we are very proud." With that, the group boarded the car and disappeared into the snowstorm.
