Foundation pit water inrush treatment method based on water storage back pressure
The invention discloses a foundation pit water inrush treatment method based on water storage back pressure, which comprises the following steps of: piling up sandbags at a water inrush position of a foundation pit, and pumping and draining accumulated water in the foundation pit; stopping water pumping and drainage in the foundation pit when the filling sandbags cannot control water burst, and storing water in the foundation pit to achieve water pressure balance inside and outside the foundation pit; a 1 m drill hole is formed outside the foundation pit support structure in the range close to the water inrush for sampling, and the geological condition and leakage holes are found out; plain piles are constructed for isolation, and meanwhile the leakage holes are filled from the plain piles to the enclosure structure by grouting from the ground; and after grouting meets the condition, grouting is stopped, and then water pumping and drainage are conducted in the foundation pit. By the adoption of the method, the water flow and the flow speed of sudden gushing can be rapidly reduced, the problem that water gushing carries sand is effectively solved, and the effect of enhancing the lateral stability of the foundation pit support structure can be achieved.
本发明公开了一种基于蓄水反压的基坑突水处理方法，其包括以下步骤：向基坑突涌水处堆填沙包，并对基坑内积水进行抽排水；当堆填沙包无法控制突涌水时，停止基坑内抽排水，通过基坑内蓄水，使得基坑内外达到水压平衡；在突涌水临近范围沿基坑围护结构外放1m钻孔取样，查明地质情况及渗漏孔洞；施工素桩隔离，同时在素桩至围护结构之间通过从地面注浆填充渗漏孔洞；注浆满足条件后停止注浆，再进行基坑内抽排水。采用本发明，既能快速降低突涌水流量和流速，有效解决涌水带砂问题，又能起到加强基坑围护结构侧向稳定的作用。
