Description

Technical Field

[0001] The utility model relates to the technical field of inspection wells, in particular to a square prefabricated assembly type inspection well. Background Art

[0002] Inspection wells are set up for the convenience of maintenance and installation of urban underground infrastructure such as power supply, water supply, drainage, sewage, communication, cable TV, gas pipes, and street light lines. Generally speaking, inspection wells are set up at pipeline intersections, bends, places where pipe diameters or slopes change, and at certain intervals on straight pipe sections to facilitate regular inspections, cleaning and dredging or downhole operations and inspections. Inspection wells are composed of well seats, well shafts, well covers, and related accessories. They are well-shaped structures used for clearing and inspecting wells. Inspection wells are set up with well covers, well shafts, and well seats. Of course, there are some related professional accessories for installation and use. Common inspection wells can be divided into concrete inspection wells, plastic inspection wells, brick inspection wells, etc. according to the materials used. They can also be divided into rainwater wells, sludge wells, oil isolation inspection wells, etc. according to their functions. They can be divided into round inspection wells, square inspection wells, and fan-shaped inspection wells, etc. according to their shapes.

[0003] In the prior art, a Chinese patent with patent publication number CN210827571U discloses a square prefabricated assembled inspection well. The square prefabricated assembled inspection well is achieved by loosening the fixing nut and knocking the bracket backward, so that the bracket drives the block to disengage from the sleeve, so that the sleeve is tightened and disengaged from the mounting hole, thereby achieving the effect of simple and convenient disassembly. Compared with the traditional embedded climbing handle, the socket of the inspection well is more convenient and simple to install and disassemble, thereby improving the safety performance of the inspection well, making the inspection well easy to maintain, and improving the practicality of the inspection well.

[0004] The fixing nut of the device is threadedly connected to the bracket. The bracket can be disassembled by loosening the fixing nut. Tools are needed to disassemble and install the fixing nut, which is inconvenient to operate. In addition, the fixing nut and the bracket are both in the inspection well, which is humid and prone to rust and corrosion, causing the threads at the connection between the nut and the bracket to rust, making the fixing nut difficult to twist, affecting the disassembly and installation of the bracket. Therefore, a square prefabricated inspection well is designed to solve the above problems. Utility Model Content
