(New Year to the grassroots) from piecemeal to 3D positioning The science and technology Spring Festival Road of "mountain patrolling people" in the depths of Qinba
Xi'an, January 19 (China News Network) (Zhang YuanYuhai, Zhang Lin) "Everyone pays attention to safety, with steady feet and tight hands. Wang Chaff, the foreman of the Bashan Bridge Tunnel Workshop Inspection Workshop of the Ankang Engineering Section of China Railway Xi'an Bureau Group Company, shouted loudly in the middle of the mountainside with his throat. Every winter, taking advantage of the favorable opportunity of grass dry and stone dew, Wang Cha will lead the staff to inspect the hidden dangers of flood prevention in the mountains in the pipe, focusing on the hidden dangers of the mountains and slopes along the line.
The Ankang Engineering Section has jurisdiction over the Xiangyu, Xikang and Yang'an railway lines, which wind along the banks of the Qinling Daba Mountain and the Han River. Here the mountain slope is steep, there are more large rocks on the mountain, and every year the Spring Festival, in order to ensure that the train under the mountain can run safely, more intensive mountain sweeping work is carried out here.

At 8:00 a.m., Wang Bran led 4 employees, carrying safety ropes, steel brazes, hammers, and yellow overalls, and began to climb the main peak of "Chaotianliang". In order to climb this mountain with a slope of 70 degrees and a vertical height of 90 degrees, Wang Cha and his co-workers suffered a lot. Over time, they stepped out of a sheep gut trail on a steep hill with no road, only one foot wide, and they could walk like "flying". Standing at the top of the mountain, at the foot of the 43-year-old Xiang-Chongqing Railway, it passes through the Qinba Mountains at the junction of Sichuan and Shaanxi.
Opening the road in the mountains and climbing up the rocks is a common meal for the workers of the public works bridge and tunnel. Sometimes although the mountain is not high, but the road is extremely difficult to walk, while climbing to observe the exposed rocks, every time the mountain reaches a certain height, there is a layer of protective net to cover the stones, and each exposed mountain has a layer of protective net wrapped protection. But over time, rocks weighing several tons can compress the protective net, and these dangerous rocks must be eradicated in order to ensure the safe operation of the train under the mountain.
"This stone is visually tall, almost three or four cubic meters." After more than 3 hours of arduous trekking, Wang Cha and his co-workers came to the top of the mountain and stopped in front of a dangerous rock. The terrain of this dangerous stone is complex, the dangerous rock is half embedded in the cliff, and none of the places can be settled next to it.
Wang Chaff took photos and numbers of dangerous stones with his co-workers, included them in the B-class dangerous stone disease risk database, and formulated a detailed post-remediation plan. Under the leadership of the foreman, the workers in the work area have practiced a good kung fu of "drilling mountains and crossing mountains", and the accuracy of judging mountain diseases is as high as more than 90%.
In the past, such dangerous stones were placed, and the operators would passively defend themselves by "brushing red paint, breaking pieces, and making regular observations". But now, the Ankang Public Works Section has increased investment in scientific and technological strength during the flood season, introduced the Aowei map 3D positioning system, standing at the bottom of the mountain, through handheld equipment, you can see the geological environment, drainage paths, dangerous rock dynamics and other changes in the slope of the mountain, and can more intuitively find dangerous rocks and hidden dangers in the mountain. In the later stage, through image processing and three-dimensional modeling data analysis, they can accurately find geological hidden dangers and analyze safety risks. Up to now, the Ankang Public Works Section has inspected 705 mountain heads, and incorporated different levels of safety issues into the safety risk database, and rectified and implemented them at the first time.
A road and a train, a mouthful of steamed water, this group of simple workers, blowing the clear wind in the mountains, adhering to the mountains day by day, escorting the Spring Festival with heart, guarding the safe return of passengers. (End)
