一个深6m的基坑,原设计为垂直式土钉墙,施工中发生坍塌,通过分析事故的各种诱发因素,综合确定采用钢桩加斜支撑支护方案,经过短短4d时间的抢修,修复了坍塌的基坑侧壁,恢复道路交通完成基坑支护,为同类工程的抢修提供借鉴。
A pit depth of 6m, the original design plan uesed a vertical soil nail wall, have taken place in the collapse pit accident during the construction process. Through analysised of accidents of various predisposing factors, integrated to determine steel piles attached tilt bracing plan to rescue foundation pit.
