Grouting type leaking stoppage method of subway station open-cut interval foundation pit enclosure structure
The invention discloses a grouting type leaking stoppage method of a subway station open cut interval foundation pit enclosure structure. The method comprises the following steps that plugging materials are stacked on one side of the enclosure structure corresponding to the interior of a foundation pit to form a temporary plugging body to plug a leaking part; a grouting hole is drilled in the soil body, corresponding to one side of the exterior of the foundation pit, of the enclosure structure, a preset distance is reserved between the grouting hole and the leakage position, and the depth of the grouting hole is lower than the preset height of the leakage position; and a grouting machine is adopted for grouting into the grouting hole till the water leakage phenomenon at the leakage position is eliminated. The grouting type leaking stoppage method has the advantages of being low in cost, good in leaking stoppage effect, wide in application range and the like.
本发明公开了一种地铁站明挖区间基坑围护结构的注浆式堵漏方法，包括采用封堵物堆码在围护结构对应于基坑内部的一侧，形成临时封堵体对渗漏处进行封堵；在围护结构对应于基坑外部一侧的土体中钻注浆孔，注浆孔与渗漏处之间具有一个预设间距，且注浆孔的深度低于渗漏处一个预设高度；采用注浆机向注浆孔内注浆，直至渗漏处的漏水现象消除的步骤。该注浆式堵漏方法具有成本低、堵漏效果好、适用范围广等优点。
