北京地铁六号线车公庄西站顺穿一条4400mm×2100mm热力管沟,横穿一条3300mm×2570mm的热力管沟,下穿12700mm×12500mm的热力小室群,在下穿施工过程中,有504根热力围护桩侵入车站内,需大量截断施工热力管沟和热力小室时灌注的围护桩,如何快速安全的截断这些热力围护桩,关系到车站能否按时竣工和施工安全。
Chebei Gongzhuang West Railway Station on the 6th line of Beijing Subway runs through a 4400mm × 2100mm heat pipe trench, crosses a 3300mm × 2570mm heat pipe trench and runs through a 12700mm × 12500mm heat chamber group. During the construction process, there are 504 heat The retaining pile intrudes into the station, which requires a large number of retaining piles when the heat pipe trench and the thermal chamber are cut off. How to quickly and safely cut off these thermal retaining piles relates to whether the station can be completed on time and the construction is safe.
