Background

In high-rise buildings, house buildings and underground engineering structures, engineering accidents caused by problems of sand flowing, piping, pit bottom instability, pit wall collapse and the like almost occur every year, so that surrounding underground pipelines and buildings are damaged to different degrees. In order to avoid the adverse effect of underground water on buildings, prevent the collapse of the soil body of the side slope of the foundation pit and ensure the construction safety and the engineering quality, a method for reducing the water level of the underground water is required to ensure the smooth construction of the engineering.

The most common precipitation method is to uniformly excavate a plurality of precipitation wells on the ground of a construction site in advance and then reduce the groundwater level by pumping a large amount of water. However, after the construction is completed, the plurality of dewatering wells need to be sealed, and the traditional well sealing method generally adopts a method that a submersible pump is placed in the well, a water outlet pipe extends out of the well, concrete is poured into the well, and finally a waterproof layer is laid after a bottom plate is packaged above the well mouth to tightly press the well mouth.

The submersible pump is left in the pipe well and is always in a working state by adopting a traditional well sealing mode, and the submersible pump is easy to burn out after long-term use. After the submersible pump is damaged, underground water cannot be pumped out, and the pipe well is sealed by concrete, so that the submersible pump is not easy to maintain. And the well sealing process is complicated, and if the concrete filling is incomplete or other well sealing links are not constructed in place, the phenomenon that underground water seeps out from the joint of the well mouth and the bottom plate is easy to occur. When groundwater rises and the submersible pump is always in a working state and is burnt, the hidden danger of water seepage due to untight plugging can occur.
