Well point tube structure and well point construction method

Abstract

The invention relates to a well point tube structure and a well point construction method, relates to the technical field of well point precipitation and solves the problem that filter materials are possibly stacked on a well point mouth. The well point tube structure comprises a tube body and a stirring device, wherein the stirring device comprises a mounting sleeve; the mounting sleeve fixedly sleeves the peripheral side of the tube body; the bottom of the mounting sleeve is symmetrically equipped with connecting columns; the bottoms of the connecting columns are rotatably connected to a connecting base; a connecting hole is formed in the middle part of the connecting base; the tube body passes through the connecting hole; the peripheral side of the connecting base is equipped with a stirring rod for stirring the connecting base to rotate; the bottom of the connecting base is uniformly and fixedly provided with connecting rods in a spaced mode; and sides, away from the connecting base, of the connecting rods are equipped with stirring assemblies. The well point tube structure has the effect of being capable of reducing filter materials stacked at the well point mouth.

Description

technical field [0001] The invention relates to the technical field of well point dewatering, in particular to a well point pipe structure and a well point construction method. Background technique [0002] Well point dewatering is to arrange well point pipes at regular intervals around the foundation pit. The top of the well point pipes is connected to the water collection main pipe, and then the accumulated water in the soil layer around the foundation pit is pumped out by a vacuum suction pump. [0003] Currently, see figure 1 , a well point pipe, comprising a pipe body 1, and a filter net made of nylon material is wound around the outer peripheral side of the pipe body 1 near the bottom. Before use, open a well point hole around the foundation pit, then insert the pipe body 1 into the well point hole, and then fill the filter material around the pipe body 1 and the well point hole, so that the accumulated water in the soil layer is first filtered by the filter material ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: after the well point hole is opened, the pipe body 1 is inserted into the well point hole first, and then the filter material is poured manually. When there is a lot of material, the filter material is easy to accumulate in the well point mouth of the well point hole, and cannot fall into the well point hole evenly
