Gradually-pressed direct pressure water pumping tube well

Abstract

The invention relates to a gradually-pressed direct pressure water pumping tube well. The water pumping tune well comprises a bottom conical press-in tube joint, latticed filter cartridge embedded water storage tube joints and a top pressurizing tube joint, wherein the bottom conical press-in tube joint is movably connected to the lower end of one latticed filter cartridge embedded water storage tube joint, at least one latticed filter cartridge embedded water storage tube joint is arranged, and the top pressurizing tube joint is movably connected to the upper end of the uppermost latticed filter cartridge embedded water storage tube joint. The gradually-pressed direct pressure water pumping tube well can simplify the precipitation process, a tube well prearranged in advance is changed toa manner that along with a process of earth excavation, the tube well is pressed into an earth body in advance along with earth excavation according to the progress direction to pump water, the tube well can be continuously pressed into the earth body to be deepened along with deep excavation of earth, and at the moment, a water pumping facility can go deep along with the tube well without being changed; and due to the fact that a gradually-pressed pressure water pumping mode is adopted, the position of a well tube can be increased, decreased or changed at any time according to the earth excavation current situation, and the earth excavation requirement is met.

Description

technical field [0001] The invention relates to the technical field of drainage and drainage of earthwork in building construction, in particular to a step-by-step direct pressure water intake pipe well. Background technique [0002] In engineering earthwork excavation construction, it is necessary to drain or dewater the soil first. At present, most projects use tube well pumping, but the existing tube wells are relatively complex in structure and construction is cumbersome. Generally, it is necessary to form a hole for the tube well first, and then set a soil retaining filter layer around the tube. When the depth of the tube well is relatively deep, after excavation of the earthwork, the exposed upper part of the tube well must be reinforced or the pumping facilities must be changed in sections, resulting in an increase in the labor and materials used in the project, resulting in problems such as high pumping costs and long time consumption.
