Tank settling dewatering device

Abstract

The invention relates to the field of dewatering engineering, and discloses a tank settling dewatering device. The tank settling dewatering device comprises a water storage tank (1), a filter (2), a water pipe (3) and a water pumping device (4), wherein the water storage tank (1) is a container which is deeply buried in earth; the filter (2) comprises a waterflow channel and a filter film; and thewaterflow channel is connected with the water storage tank (1), the outer side of the waterflow channel is wrapped with the filter film, the filter (2) deeply buried in earth, the water pipe (3) is connected with the water storage tank (1) and extends to the surface of the ground, the water pumping device (4) is a device which pumps water out of the water storage tank (1) through the water pipe (3), water in the earth is collected through the filter (2) into the water storage tank (1) and then pumped out from the water storage tank (1), and the dewatering purpose is achieved. The tank settling dewatering device is low in manufacturing cost, the crossed portions of the dewatering device and other construction engineering are small, no well pipe needs to be arranged, dewatering constructionis quick and convenient.

Description

technical field [0001] The present invention relates to the field of precipitation engineering in the field of geotechnical engineering. Background technique [0002] In the construction or maintenance of underground engineering, it is often accompanied by precipitation engineering to facilitate engineering construction or maintenance by lowering the groundwater table or pressurized water head. For example, in the foundation pit project, it is often accompanied by the dewatering project. For example, in the anti-floating project, the groundwater table can be lowered by precipitation to reduce the buoyancy. In the leak plugging project, the water head difference of the leak can also be reduced by dewatering. Existing dewatering wells generally use well pipes for dewatering or light well point dewatering. The structure of dewatering wells generally includes three parts: well pipes, filter screens and filter materials. The well pipe can be a tubular structure such as partially...

AI Technical Summary

Problems solved by technology

Existing dewatering technologies all require well pipes, which are expensive to construct, and are often damaged during the excavation process, resulting in abandoned wells. In addition, during foundation floor construction, the well pipes need to be sealed due to the need for continuous dewatering to cause the well pipes to pass through the floor. Well treatment, high cost
