Plugging method for inrush water at bottom of foundation pit
The invention provides a plugging method for inrush water at the bottom of a foundation pit, which comprises the following steps of: embedding a drainage pipe and pouring a back pressure concrete platform at a water burst point on the inner side of the foundation pit, vertically penetrating through the back pressure concrete platform by the drainage pipe, constructing a circle of retention wall on the constructed back pressure concrete platform, and draining the burst water to the upper surface of the back pressure concrete platform by the drainage pipe, accumulated water on the inner side of the retention wall is collected and discharged; through the steps, the difference of water heads inside and outside the foundation pit can be reduced, the grouting effect is improved, the communication position inside and outside the pit can be found out, the grouting range is defined, plugging work is rapidly completed, the plugging structure is easy to dismantle, and the influence on the construction period is small.
本发明提供一种用于基坑底突涌水的封堵方法，先在基坑内侧涌水点位置埋设引流管，浇筑反压混凝土台，所述引流管竖向穿过反压混凝土台，然后在已施工完成的反压混凝土台上施做一圈挡水墙，引流管将涌水引流至反压混凝土台上面，通过汇集挡水墙内侧的积水，并将积水排出；本发明通过上述步骤能减小基坑内外水头差，提高注浆效果，能摸清坑内外联通位置，明确了注浆范围，快速完成封堵工作，且封堵结构易拆除，对施工工期影响小。
