Problems solved by technology

The existing inspection wellhead and well base are coaxially arranged. Due to the large diameter of pipes such as rain and sewage pipes, the coaxial arrangement of the inspection wellhead and the well base will cause the lower part to be suspended. It is very inconvenient for the operator to enter the inspection well during maintenance.

Abstract

The invention relates to water supply and drainage facilities, in particular to a more convenient plastic offset inspection well. The offset inspection well includes the upper part as the inspection wellhead, and the lower part as a tubular seat for connecting with the drainage pipe; the inspection wellhead is vertically upward, the seat is arranged horizontally, and the inspection wellhead is located on the axial side of the seat; The two ends of the seat body and the middle part of the seat body are perpendicular to the inspection wellhead, at least two places are provided with pipe sockets connected to the drainage pipe; the inspection wellhead is extended downwards and a shell is provided, and the shell and the seat body form an intersecting combination , the lower end of the housing is smoothly connected with the seat body; the vertical section of the inner wall of the housing is provided with a ladder; the inner wall of the housing below the ladder is provided with a protruding stepping platform. The structure of the invention is simple, firm, easy to process, assemble and use, high in strength, durable, corrosion-resistant and low in cost.

Description

technical field [0001] The invention relates to water supply and drainage facilities, in particular to a plastic inspection well. Background technique [0002] Plastic inspection wells have become a common facility in the occasions of fluid transportation such as urban water supply and drainage, as well as the laying of cables underground. Especially in urban rainwater and sewage drainage pipe network systems, inspection wells are often used for dredging and maintenance of rainwater and sewage drainage systems. [0003] Inspection wells in the prior art are more and more inclined to use materials, which are corrosion-resistant, renewable, and easy to install. The existing plastic inspection well is formed by plastic injection molding or compression molding, and its structure generally includes a well base, an inspection well head and a pipe socket arranged on the side of the well base to connect to the drainage pipe. The existing inspection wellhead and well base are coaxi...
