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

Embodiment Construction

[0021] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0022] Such as figure 1 , 3 As shown, the variable-angle plastic inspection well includes a well base 1, and a main shaft 2 is provided on the well base 1. Several branch shafts 3 are fixed on the side of the well block 1, and the inner ends of the branch shafts 3 communicate with the main shaft 2. The outer end of the branch shaft 3 is plugged with an elbow joint 4, and the inner end of the elbow joint 4 and the joint surface of the outer end of the branch shaft 3 are provided with an annular seal 13 for sealing the two. To ensure the sealing between the elbow joint 4 and the branch wellbore 3, and improve the sealing effect of the inspection well, the inner end of the elbow joint 4 is positioned both radially and axiall...

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...
