摘要
以某洞库破碎带施工处理为例,介绍了加固的过程,经实践验证后,得出采用超前小导管注浆结合格栅拱架和径向锚杆加喷射混凝土方法施工能够解决破碎带塌方问题,可供类似洞库施工参考。
Taking a construction treatment of the underground structure fracture zone as an example,the process of the strengthening was introduced which was proved that the advanced small catheter grouting with grille arch frame and radial anchor and jet concrete method can solve the problems of collapse underground structure.This can be a reference example for similar construction of underground structure.
