Pipe well wall vertical filter box

Abstract

The invention relates to a pipe well wall vertical filter box, which includes a box body detachably installed on a pipe well lattice frame body. The box body comprises an inner box body and an outer box body, a plurality of vertical partition plates are arranged in an inner cavity of the inner box body and divide the inner box body into a plurality of filtering flow channels, each filtering flow channel is filled with a main filtering material respectively, a water inlet of each filtering flow channel is located at the upper part of an inner box body and outer box body partition plate, a wateroutlet of each filtering flow channel is located at the lower part of an inner box body inner plate, and the water inlet and the water outlet are equipped with blocking screens respectively; an outerplate of the outer box body is equipped with water permeable holes, the outer box body is filled with primary filtering filler, a transverse partition plate is arranged at a middle part in an inner cavity of the outer box body, the transverse partition plate, an outer box body top plate and an outer box body bottom plate are respectively equipped with water flowing holes, and the water flowing holes are equipped with water flowing hole block screens. The pipe well wall vertical filter box is used on a pipe well lattice frame body gradually and directly pressed into a soil body and used as a pipe well side wall for retaining soil and filtering water, the filter box can be replaced and used according to different soil textures, and has the characteristics of convenient use, good water storage effect, and long service life.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a tube well wall vertical filter box. Background technique [0002] The current water pipe well generally drills a well hole in the soil, then places a central well pipe in the well hole, and then drops a graded filter material around the central well pipe as a filter soil retaining layer. This kind of water intake tube well needs to drill a larger well hole first, and because it is difficult to accurately control the gradation and position during the grading process of adding filter materials, it is easy to cause the filter layer of the water intake tube well to fail due to blockage, and the water storage effect is poor. The service life of the water pipe well is short. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a tube well wall vertical filter box, which is used on the tube wel...
