Intercepting ditch to block the "monsters"
"One, two, one, two, one..." At 14:00 on June 10, at the place 251 kilometers and 100 meters away from Pengyang to erlipu section of Baozhong railway, a dozen employees of Zhongwei Public Works section stood on the top of the mountain more than 50 meters high, holding the hemp rope with both hands and feet on the ground, bending up, shouting the number and dragging the concrete felt at the bottom of the slope. They should lay a "road" for the possible mountain torrents here to ensure that the rainwater can bypass the terrain Railway. "There was no intercepting ditch here. This year, we built a new intercepting ditch at the middle of the mountain to connect with the existing drainage system, so as to improve the flood discharge and discharge system of the railway in the mountain area and consolidate the flood dike." Yang Junning, site director and deputy director of Zhongwei bridge and tunnel workshop, said. In the hot noon, Yang Junning and a young worker rechecked the slopes of the intercepting ditch in all directions, and the site staff raised a stone hammer to smash deep holes in the ground. After the foundation treatment, a piece of concrete felt was paved from the top of the hill to the bottom of the slope. Zhang Xingqi, an employee, anchors the steel bars, and Xi Yongchao shovels the earth and presses the edge joints. Everyone is sweating and working hard. At 18 o'clock, a intercepting ditch about 80 meters long went straight through the bottom of the ditch from the top of the mountain. Looking at the completed intercepting ditch, everyone has a sense of achievement. Since the flood season, Zhongwei Public Works section has been seeking the actual effect of engineering renovation from the root. For places with weak flood resistance, such as sandy embankment, U-shaped subgrade, cliff wall, etc., measures such as sand excavation and filling, rubble support, cutting mountains and increasing ditches have been taken to comprehensively improve the flood control capacity of line bridge equipment.
