A kind of dewatering well structure and construction method

Abstract

The application discloses a structure and construction method of a dewatering well, which relates to a dewatering well, which improves the drainage efficiency of the dewatering well, which includes a well hole and a well pipe installed in the well hole, and the well pipe is provided with a filter section , the well pipe is rotatably connected with a cloth receiving roller and a cloth outlet roller, and both the cloth receiving roller and the cloth outlet roller extend along the axial direction of the well pipe; The water filter gauze, the well pipe is provided with a cloth outlet and a cloth receiving port, the cloth outlet and the cloth receiving port are arranged close to each other, and the cloth outlet and the cloth receiving port extend along the axial direction of the well pipe, One end of the water filter gauze protrudes from the cloth outlet and is wound on the filter section along the circumference of the well pipe, and then stretches into the cloth receiving port to connect with the cloth receiving roller; The driving assembly that makes the take-up roller take up the filter gauze. In the present application, through the arrangement of the cloth receiving roller and the cloth discharging roller, the replacement of the water filter gauze can be realized, and the drainage efficiency of the dewatering well can be improved.

Description

technical field [0001] The present application relates to a dewatering well, in particular to a dewatering well structure and construction method. Background technique [0002] Dewatering well engineering is the most commonly used dewatering method in engineering construction at present. The so-called dewatering well engineering refers to excavating a certain number of dewatering wells at a certain distance around the foundation pit of the proposed project and in the middle of the foundation pit. The well pipe is a dewatering method in which the pumping pipe is extended into the well pipe, and the groundwater is pumped continuously through the water pump, so that the groundwater level in the foundation pit is always lower than the operation surface of the foundation pit. This dewatering method has the characteristics of large well spacing, good drainage effect, independent multi-well points, simple dewatering equipment and operation process, low engineering cost, etc., and i...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: as the use time of the water filter gauze increases, more debris is easily attached to the water filter gauze, which leads to the blockage of the water filter gauze, thereby affecting the filtering effect of the water filter gauze , reducing the drainage efficiency of the precipitation well
