兰新线武嘉段铁路全长480正线公里,该施工标段地处甘肃西北部酒泉地区的河西走廊西段,祁连山脚下,海拔平均在1450～1800米。戈壁、沙漠、丘陵、平原错纵分布,年平均气温走廊地带为5～9℃;南北山地为4～6℃,年降水量37～176mm,属于大陆性温带干旱气候。清水至嘉峪关铁路北侧为312国道,铁路两侧还有县级公路,公路运输便利。沿线车站由西向东依次为嘉峪关、文殊、酒泉、东洞、红山堡、金佛寺、上河清、丰乐滩、清水。这里主要探讨的是兰新线武嘉段酒泉至嘉峪关区间,由于该区间在武嘉电气化工程中属于非提速区段,在非提速区段ν≤100km/h,铁道电力牵引供电接触网工程φ400等径砼柱在直埋区段组立,有着其独特的施工方法与工艺流程。
The new railway line of Wujiajie in Lanxin Line is 480 km long. The construction section is located in the western section of Hexi Corridor in the Jiuquan area in the northwest of Gansu. At the foot of the Qilian Mountains, the elevation of the Lanzhou section averages 1450-1800 meters. Gobi, deserts, hills and plains are distributed in the wrong direction. The annual mean corridor temperature ranges from 5 ℃ to 9 ℃. The north and south mountain ranges from 4 ℃ to 6 ℃, and the annual precipitation is 37 to 176mm. It belongs to the continental temperate arid climate. The north of Qingyousui to Jiayuguan Railway is State Road 312, with county-level highways on both sides of the railway and convenient road transport. The stations along the line from west to east are Jiayuguan, Manjusri, Jiuquan, Dongdong, Hongshanbao, Golden Buddha Temple, Shangheqing, Fengle Beach and Qingshui. The main discussion here is the new line Wuchang section of the Lugar section from Jiuquan to Jiayuguan interval, as the section in Wujia electrification project belongs to the non-speeding section, non-speed section ν ≤ 100km / h, the railway electric traction power supply catenary project φ400 Diameter concrete column in the buried section of the group, has its unique construction methods and processes.
