Setting up "golden bell cover" at flood control points

"If the hidden danger is removed from the root of the" 311 ", the safety of train operation in flood season will be firmly guaranteed." On July 15, Liu Xue, a worker at the guard point of the Junshi Miaoqiao road work area of Hanzhong Public Works section, said happily. "311" refers to the first-class flood control point at 760m-800m downstream of Baoji Chengdu line. This flood control point is located in Micang mountain at the southern foot of Qinling Mountains, with Jialing River on one side and a cliff more than 60 meters high on the other side. The dangerous rocks protrude from the top of the line. In April this year, the person in charge of Xi'an Bureau Group Co., Ltd. of China railway went to work at the flood control point, and decided to change prevention into treatment and build steel arch support under dangerous rocks to completely eliminate the risk of rockfall on the line. In the mountainous area, the existing railway construction is narrow, and the machinery can not get in; there are many dangerous rocks in the surrounding area, which is prone to rock fall; there is no road nearby, so the construction materials and living supplies can only be transported by rail cars, or even by hand, mules and horses In the face of these difficulties, the construction personnel tried every means to solve them, insisted on 24-hour three shift operation, fought for 55 days, and finally completed the project construction. Now, standing on the Bank of the Jialing River, looking at the flood control point from afar, the steel arch made of 490 tons of steel and cement is like a "Golden Bell Jar", which keeps the dangerous rocks out and protects the transportation safety of Baoji Chengdu line. Not far away, Liu xueshou spent four years in a detention house transformed from a shelter. Among the 14 workers in their work area, 4 specially guard the "311" flood control point. Liu Xue was on duty with Liu Xue, and Liao Haoyu, the monitor of military Miaoqiao road work area. Liu said: "our main task is to check whether there are landslides and falling rocks near the line, and to maintain the joint control of aircraft guarding. After a shift, we have to pick up more than 40 trains. "
