Vacuum foundation-pit deep-well precipitation apparatus

Abstract

This invention discloses a vacuum deep well water-lowering device including a vacuum pump, a deep wall filter pipe, a pipe cover, a vacuum total main, a vacuum branch water pipe and a discharging pipe, in which, the filter pipe cover is set at the top of a filter pipe and connected with it in seal, the body of the filter pipe is distributed uniformly with many small holes, the discharging pipe and the water main are connected at both ends of the pump, the branch pipe and the main are connected and enter into the filter pipe via the cover set with small holes and the branch pipe is set with small holes.

Description

technical field [0001] The invention relates to foundation pit dewatering equipment for foundation construction of civil engineering, in particular to a vacuum foundation pit deep well dewatering equipment. Background technique [0002] Deep foundation pit excavation is an important construction procedure for modern large-scale underground structures. Reducing the groundwater level in the foundation pit is also called groundwater control. The higher the groundwater level of the environment, the deeper the depth required for the foundation, and the greater the difficulty of its construction. In order to prevent changes in the underground surroundings from causing harm to the environment and facilities around the foundation pit, the method of lowering the groundwater level at deep well points is generally used to solve such technical problems and special equipment is used. The deep well point dewatering equipment in the prior art Including vacuum pumps, deep well filter tubes...

AI Technical Summary

Problems solved by technology

In order to prevent changes in the underground surroundings from causing harm to the environment and facilities around the foundation pit, the method of lowering the groundwater level at deep well points is generally used to solve such technical problems and special equipment is used. The deep well point dewatering equipment in the prior art Including vacuum pumps, deep well filter tubes, submersible pumps, etc. The difficulty is that as the depth of the well increases, the difficulty of pumping water increases, and the submersible pumps are difficult to dive. The one-time investment is large, the operating cost is high, the material loss is large, and the use effect is not ideal.
