地铁区间横通道内排水管线穿插防漏施工技术

Construction Techniques of the Drainage Pipeline Leakage-proof Interlude in Subway Interval Tunnel

针对北京地铁10号线国贸站至双井站区间,通风井内集水池引入管线管道的渗漏问题,在进行多方案比选的基础上,采取了穿插防漏施工处理方法。该方案在不破坏原工程结构的情况下,成功地解决了结构内直角弯曲管道渗漏水问题,取得了良好的技术效果和经济效益。

According to Beijing subway line 10 Guomao station to Shuangjing station interval, ventilation pipe sink into pipeline inner collection of leakage problem, in more than scheme based on the leak, take into construction method. The scheme in the engineering structures, which successfully solved the inside structure, bending pipe leakage problem fight obtained good effect and economic benefit.
