Foundation geological survey hole gushing water stopping and pressure releasing device and method
The invention discloses a foundation geological survey hole gushing water stopping and pressure releasing device and method in the technical field of constructional engineering, and the device comprises a water stopping mechanism arranged in a survey hole to block the survey hole, the water stopping mechanism is provided with a drainage pipeline to discharge gushing water in the survey hole, the drainage pipeline is provided with a water stopping valve, and the drainage pipeline is provided with a pressure relief valve. The drainage end of the drainage pipeline communicates with a water pipe, the tail end of the water pipe communicates with a water pump, and the water stopping mechanism comprises a lower annular plate, an upper annular plate and a sealing gasket arranged between the lower annular plate and the upper annular plate. Through the combined action of the water pump, the water stop ring plate and the drain pipe, the pressure applied by the confined water layer to the overburden layer in the foundation pit is more effectively released, the situation that a large amount of confined water flows into the exploration hole is avoided, and the stability of the construction process can be effectively guaranteed.
本发明公开了建筑工程技术领域的基础地质勘察孔涌水止水释压装置及方法，包括：设在勘察孔内的止水机构，以对勘察孔进行封堵，所述止水机构上设有疏水管道，以将勘察孔内的涌水排出，所述疏水管道上设有止水阀门，所述疏水管道的排水端上连通有水管，所述水管的末端上连通设有水泵，所述止水机构包括下环板、上环板以及设在下环板与上环板之间的密封垫，本发明中有效解决承压水孔封堵的问题，通过水泵、止水环板以及疏水管的共同作用更加有效的释放承压水层对基坑内覆土层所施加的压力，不会出现勘察孔大量喷涌承压水的情况，可以有效的保障施工过程的稳定性。
