Punching and grouting type leaking stoppage method for subway station open-cut interval foundation pit enclosure structure
The invention discloses a punching and grouting type leaking stoppage method for a subway station open-cut interval foundation pit enclosure structure. The punching and grouting type leaking stoppage method comprises the steps that grouting holes penetrating through the foundation pit support structure are drilled in the position, away from a leaking position by a preset distance, of the foundation pit support structure; a grouting pipe is buried in the grouting hole, the grouting pipe stretches into the soil body on the outer side of the foundation pit enclosure structure by a preset length, a gap between the grouting pipe and the inner wall of the grouting hole is blocked through a plugging material; a grouting machine is adopted for grouting the soil body on the outer side of the foundation pit enclosure structure through a grouting pipe till the water leakage phenomenon at the leakage position is eliminated; and the grouting pipe is plugged. The punching and grouting type leaking stoppage method has the advantages of being good in leaking stoppage effect, convenient and fast to construct, suitable for the conditions of large leakage amount and large water pressure 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打孔注浆式堵漏方法，包括在基坑围护结构上距离渗漏处预设间距的位置钻设贯穿基坑围护结构的注浆孔；在注浆孔中埋设注浆管，注浆管伸入至基坑围护结构外侧的土体内预设长度，采用堵漏材料将注浆管和注浆孔内壁之间的缝隙封堵；采用注浆机经注浆管向基坑围护结构外侧的土体内注浆，直至渗漏处处的漏水现象消除；将注浆管封堵的步骤。该打孔注浆式堵漏方法具有堵漏效果好、施工方便快捷、适用于大渗漏量及大水压情况等优点。
