Jiaoguang Living Room| "Dushan People" on the Yingxia Line

The 2022 Spring Festival starts from January 17 to February 25, a total of 40 days. The South Rail is expected to send 21.48 million passengers. During this busy Spring Festival, the Yingxia Railway, which mainly connects the two provinces of Gansu and Fujian with freight, also ushered in the busiest transportation period.

On January 16, at 7:20 a.m., Lu Chaojie, foreman of the Guikou Road and Bridge Engineering Zone of the Yong'an Public Works Section of the South Railway, and his co-workers were conducting mountain searching and rock sweeping operations on a steep slope of nearly 70 degrees at 421 kilometers of the Yingxia Line. Along the Yingxia Line, the mountains are densely forested and the ravines are longitudinal, and there are hidden dangers of slope collapse and collapse of rocks during the flood season. Lu Chaojie has jurisdiction over the maintenance of road and bridge equipment for 50 hills, 65 culverts, 7 bridges and 15 tunnels within 30 kilometers of the construction area. Today's work is to temporarily deal with the new disease points searched by the aerial photography of the UAV in the early stage, and there are more than 300 hidden dangers of all sizes in the work area. They wear hard hats, wear safety ropes and carry inspection hammers to climb steep slopes, and checking for hidden dangers is both physical and technical work. In order to ensure the safety of railway transportation, they must also skillfully operate and use high-tech equipment such as unmanned aerial vehicles, anemometers, Aowei map measurements, steel reinforcement detectors, concrete rebound instruments and so on. They were jokingly called the "Tushan people" on the Yingxia Line by their colleagues.

Lu Chaojie of Yong'an Engineering Section: "We first used drones to fly through more than 50 large and small cliffs in the management area, and then we also numbered more than 300 dangerous rocks one by one, carefully drew out the 'Lone Rock Dangerous Rock Series Map', and then tied the dangerous rocks according to the type of disease, first of all, the rocks with the highest danger factor were removed to ensure driving safety." ”

Secondly, they drill holes in the rock, and then insert the anchor rod, when placing the protective net, the surrounding protective net is "stitched" on the anchor rod, and then the anchor cable is buckled to strengthen, so that the stone is not easy to break the grid, leaving about 5 cm of space for the stone, which not only reduces the daily work, but also reduces the damage rate of the protective net.

As a young talent with exquisite business in the whole section, Lu Chaojie carries a pocket notebook with him and densely records many notes of experience in live combat. Emergency handling of faults, maintenance precautions, and difficult and complicated diseases encountered on the spot, he will write them down at the first time.

Every time he has a spare moment, Lu Chaojie will contact his girlfriend WeChat video link, and they plan to get married before the New Year. He said they had been together for more than 400 days and were still feeling like they had just fallen in love.

Lu Chaojie, Yong'an Engineering Duan: "I don't go home for the New Year this year, I am still on duty in the work area, with the people I love, everywhere is home." ”
