Wuxiang County section of Taijiao high speed railway is in the stage of track laying construction
In recent days, at the construction site of Wuxiang County section of Taijiao high-speed railway, a group of 500m long rails are placed in sleepers by large track laying machines. It is understood that since September 26, Wuxiang County section has actively promoted the track laying work, which also means that the Taiyuan Jiaotong high speed railway has entered the track laying construction stage in an all-round way. Up to now, the section has completed 9.9 km of track laying on the left main line and 5 km of manual track laying and folding contract on the right main line.
"the total length of track laying in this section is 631.5km, and there are many alternating ballasted and ballastless tracks. All track laying works are expected to be completed within 8 months. At present, the track laying from Wuxiang to Yushe is under way. The length of the line is 36 kilometers, and the track laying is 72 kilometers. " According to Yao Yufeng, chief engineer of the 4th bid section of Taiyuan Jiaotong high speed railway of China Railway 12th Bureau, the contractor, the new type of track laying machine independently developed in China is adopted for the track laying, with the track laying index of 2km per day. The track laying of the whole line of
needs to complete multiple processes such as track laying, fork laying and rail welding. Facing the difficulties of high track laying standard, many cross working surfaces and short construction period, the construction unit constantly optimizes the scheme and resource allocation, adopts the most advanced engineering dispatching and transportation management information system in China, and promotes the storage of appropriate amount of ballast in advance and the increase of tooling equipment. And effective measures such as labor allocation, increasing the working face of track laying at any time according to the progress, and adhering to the "six 100%" of dust prevention and control at the construction site, to ensure that the track laying is carried out in an orderly manner according to the plan and environmental protection. There is a track laying base in the Shanxi section of the
Taiyuan coke high speed railway, which undertakes all the track laying tasks in Shanxi. The base covers two counties and three villages, passing through three villages of Nie village, Xicheng village and Song Village in Wuxiang County. There are five tracks and four functional areas, including two long track storage areas, one sleeper storage area and one comprehensive area (rail row, turnout, buckle accessories, sleeper and standard rail). From October 21, ballastless track bed construction began in Yunzhu tunnel of Wuxiang County. During the construction, the 9.9km section from Wuxiang west station to the exit of Yunzhu tunnel will be paved manually. As an important part of the "eight vertical and eight horizontal" main channel of China's high-speed railway network, the
Taijiao high-speed railway is the most convenient channel to the Yangtze River Delta economic belt and the southeast coast of Henan Province. The total length of the line is about 358km, and there are 13 stations in the whole line, including Wuxiang west station, Xiangyuan east station, Changzhi east station and Shangdang District Station in Changzhi City. The design speed is 250km / h, and it is expected to be fully opened to traffic in 2020, when Changzhi will only take 1 hour to Taiyuan. (source: Ding Deling, reporter of Changzhi daily)
