A prefabricated functional well for water supply and drainage engineering

Abstract

The invention relates to a prefabricated functional well for water supply and drainage engineering, which comprises a well seat and a well body located on the well seat. The central axes are coincident, one end of the well base facing the well body is integrally formed with annular flexible bumps connected end to end, and one end of the well body facing the well base is integrally formed with a placing groove for placing the annular flexible bump, the placing groove is integrally formed with an annular flexible bump. The depth of the groove is smaller than the height of the annular flexible bump, and the bottom of the placement groove is pressed against the annular flexible bump. The invention has the advantages of tight connection between the annular flexible bump and the placing groove, the sewage in the well body is not easy to seep out from the connection between the well seat and the well body, and the annular flexible bump and the bottom of the placing groove are always under pressure. In a tight state, the sealing effect is better.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to an assembled functional well for water supply and drainage engineering. Background technique [0002] Various functional wells in traditional water supply and drainage projects, such as inspection wells, combined wells, turning wells and gate valve wells, are all built with red bricks or bricks and then poured with concrete according to the design drawings, which are often incompatible with pipelines. Laying cannot be carried out at the same time, which not only affects the speed and progress of the project, but also wastes a lot of manpower, material and financial resources, and not only is difficult to deal with the leakage prevention of sewage wells, but also causes environmental pollution. [0003] Therefore, in the prior art, such as the Chinese utility model patent whose patent publication number is CN204282506U, discloses a kind of water supply and drainage p...

Problems solved by technology

[0005] Although the setting of the second clasp facilitates the connection between the well body and the well base, when the construction near the functional well causes slight vibration, a gap will be generated between the well body and the well base, and the The sewage is easily discharged from the gap between the well body and the well base, and pollutes the soil environment near the functional well, and the connection between the well body and the well base is poor.
