Problems solved by technology

When the depth of the tube well is relatively deep, after the 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.

Abstract

The invention relates to a step-by-step direct pressure water intake pipe well, which comprises a bottom cone press-in pipe joint, a lattice-type water storage pipe joint inlaid with a filter box and a top pressurized pipe joint. The lower end of the water storage pipe joint inlaid with the filter box has at least one section, and the top pressurized pipe joint is connected to the upper end of the uppermost lattice water storage pipe joint inlaid with the filter box. The step-by-step direct pressure water intake tube well of the invention can simplify the dewatering process. Change the pre-set tube well to the excavation process along with the earthwork. According to the progress direction, the excavation of the earthwork will be carried out by first pressing into the soil body to extract water, and it can continue to press in and deepen following the excavation depth of the earthwork. At this time, the water will be pumped. The facility can also go deep with the tube well without changing the setting. Since the method of water intake by direct pressure is adopted, the position of the well pipe can be increased or decreased at any time according to the current situation of earthwork excavation, so as to meet the needs of earthwork excavation.

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.
