A variable-angle plastic inspection well

Abstract

The invention provides a plastic inspection well with a variable angle, and belongs to the technical field of a plastic inspection well, for solving the technical problems of incapability of avoiding obstacles in a conventional well seat installation process in case of the obstacles and the like. The inspection well comprises a well seat, the well seat is provided with a main shaft, a plurality of branch shafts are fixed at the side surface of the well seat, the inner ends of the branch shafts communicate with the main shaft, outer pipe mouths of elbow joints are used for connection with external pipelines, inner pipe mouths of the elbow joints communicate with the branch shafts, and the axes of the outer pipe mouths of the elbow joints and the axes of the inner pipe mouths form inclined included angles. According to the plastic inspection well provided by the invention, if the axes of the inner pipe mouths and the axes of the outer pipe mouths of the elbow joints form the inclined included angles, the directions of the external pipelines can be changed through rotation during installation, and in case of the obstacles during the installation process, the obstacles can be smoothly avoided.

Description

technical field [0001] The invention belongs to the technical field of inspection wells, and relates to a variable-angle plastic inspection well. Background technique [0002] Plastic inspection wells, commonly known as plastic "inspection wells", are installed at the intersections, turns, changes in pipe diameter or slope, places where water falls or at regular distances on straight pipe sections, so that they can be inspected, cleaned and dredged regularly. Drainage ancillary structures. Manhole covers, shafts and related accessories have been developed for plastic inspection wells. The road load acts on the surroundings of the inspection wells through the manhole covers and well seats, avoiding the damage of road loads to the inspection wells. The well base has the function of floating up and down, which can actively adapt to the height change of the road surface. At the same time, the well shaft adopts a special well shaft, and the corresponding length can be intercepte...

AI Technical Summary

Problems solved by technology

[0004] However, the wellbore or branch pipes of the plastic inspection wells of the above-mentioned patents are all linear. If obstacles are encountered during installation, they cannot be avoided smoothly. It can only be realized by changing the position of the pipes. This is a huge project and very inconvenient. , will seriously affect the speed of the pipeline construction project
