Positioning grouting reinforcement method for underground water seepage failure treatment of foundation pit engineering
The invention discloses a positioning grouting reinforcement method for underground water seepage failure treatment of foundation pit engineering. The method is divided into two different degrees of conditions that under the condition that the seepage failure range is small, a drainage grouting guide pipe is obliquely drilled to be inserted into or obliquely jacked into a seepage failure area fortreatment; and under the condition that the seepage failure range is large, a dewatering and drainage positioning grouting guide pipe is vertically drilled to be inserted into or jacked into the seepage failure area for rapid treatment firstly, and then the drainage grouting guide pipe is obliquely drilled to be inserted into or obliquely jacked into the seepage failure area for consolidation andreinforcement treatment. According to the method, groundwater seepage failure in foundation pit engineering is treated according to conditions, efficient treatment is achieved, the construction cost is reduced, and the construction period is shortened.
本发明公开了一种用于基坑工程地下水渗透破坏治理的定位注浆加固方法，该方法分两种不同程度的情况：在渗透破坏范围较小的情况下，通过排水注浆导管斜向钻孔插入或斜向顶入渗透破坏区域进行治理；在渗透破坏范围大的情况下，先通过降排水定位注浆导管竖向钻孔插入或顶入渗透破坏区域，进行快速治理，再通过排水注浆导管斜向钻孔插入或斜向顶入渗透破坏区域进行巩固加固治理。本发明对基坑工程中地下水渗透破坏进行分情况治理，实现了高效治理、节约了施工成本和工期。
