基于地铁停运的受损隧道钢环加固施工方法

Construction Method of Steel Ring Reinforcement for Damaged Tunnel Based on Subway Suspension

以某地铁区间盾构隧道钢环加固施工为例,介绍了一种在地铁停运情况下,24 h轮班制多作业面模式的钢环加固施工方法。采用此方法进行的大型停运施工在全国为首例,极大地提高了施工效率,可为类似工程提供参考。

Taking the steel ring reinforcement construction of shield tunnel in a subway section as an example,this paper introduces a steel ring reinforcement construction method of 24-hour shift system and multi working face mode under the condition of subway suspension.This method is the first case of large-scale suspension construction in China,which greatly improves the construction efficiency and can provide reference for similar projects.
