Galvanized steel corrugated inspection well is set up for the maintenance and easy installation of urban underground infrastructure such as power supply, water supply, drainage, sewage, communication, cable TV, gas pipes, street lamp lines, etc. Generally located at pipeline intersections, bends, changes in pipe diameter or slope, and at regular intervals on straight pipe sections, it is convenient for regular inspection of ancillary structuresA technical method used in pipeline construction for the connection between pipe holes.
In pipeline construction, there are two types of pipes that use the socket method: single hole plastic pipes and porous plastic pipes. When using the socket method for connection, the inner diameter of the socket of the single hole plastic pipe should match the outer diameter of the socket; The outer diameter of the porous plastic pipe matches the inner diameter of the joint sleeve.
Socket type metal corrugated culvert pipeComposed of many pipe sections connected together, one end of the pipe section is a socket and the other end is a socket. The diameter of the socket port is locally enlarged, and its inner diameter is larger than the outer diameter of the socket end. Installation and connection involve inserting the socket of the pipe section into the socket of another pipe section and fixing it with a flange connection.
The metal corrugated steel plate inspection well itself has good ductility, strong deformation resistance, as well as advantages such as quick and convenient installation, time-saving, low cost, and environmental friendliness. At present, corrugated steel plate materials are widely used in transportation and municipal engineering to make culverts, tunnels, underground passages, underground pipelines and other engineering structures, including corrugated steel inspection wells. At present, the diameter of inspection wells in infrastructure projects is relatively small, making it inconvenient for workers to work underground. If the diameter of inspection wells is simply expanded, the area occupied by the wellhead and manhole cover on the ground will increase, which will affect the appearance of roads and driving. At the same time, the strength of the corrugated steel inspection well after increasing the diameter is insufficient, and it is difficult to connect with standard manhole covers and other facilities, making it highly dangerous and inconvenientEasy to encounter security issues. Therefore, how to improve the existing corrugated steel inspection well is an urgent problem to be solved
