Novel well pipe structure

Abstract

The invention discloses a novel well pipe structure which comprises a water filtering pipe, a water-bearing layer, an artificial sand layer, a well pipe body, a building sand layer, a clay closing layer, a locating strengthening layer, a protecting layer and a filtering assembly. The filtering assembly is arranged in the water filtering pipe. The protecting layer is arranged at the side end of thewell pipe body. The clay closing layer is arranged at the upper end of the well pipe body. The locating strengthening layer is arranged at the upper end of the clay closing layer. The novel well pipestructure is simple and reasonable in design. The filtering assembly is arranged in the water filtering pipe, the filtering assembly can effectively filter and remove impurities in the water filtering pipe, and therefore the cleanness degree of water in the water filtering pipe is ensured. The protecting layer is arranged at the side end of the well pipe body, the clay closing layer is arranged at the upper end of the well pipe body, the locating strengthening layer is arranged at the upper end of the clay closing layer, the locating strengthening layer and the protecting layer are cast intoan integrally formed structure through stainless steel, the stainless steel is high in strength and good in corrosion and abrasion resisting property, the locating strengthening layer and the protecting layer can have the function of protecting the well pipe body, the service life of the well pipe body is prolonged, and the overall stability of the structure is ensured.

Description

technical field [0001] The invention relates to the technical field of groundwater treatment, in particular to a novel well pipe structure. Background technique [0002] The most common type of groundwater intake structures is the tube well, which generally consists of a well hole, a well wall tube, a water filter tube, and a sand settling tube. The wellbore is drilled with a drilling rig. The wellbore pipe is installed at the non-aquifer to support the wellbore wall and prevent collapse. The wellbore and the orifice are sealed with impermeable materials such as clay or cement to prevent the infiltration of ground sewage: filter The water pipe is installed at the aquifer, and its main function is to filter water and sand in addition to the well wall pipe; the bottom of the well pipe is a sand settling pipe, which is used to deposit cement sand and prolong the service life of the well. The design of the existing well pipe structure is unreasonable, so it is urgent for those ...
