Description

Technical Field

[0001] This utility model relates to the field of inspection well technology, and more specifically, to a prefabricated, modular inspection well. Background Technology

[0002] Inspection wells are important facilities in underground pipeline systems, used for inspecting and maintaining pipelines, and are indispensable in municipal drainage, water supply, and gas projects. Traditional inspection wells are mostly constructed by on-site pouring of concrete or brickwork, requiring on-site formwork, reinforcement binding, pouring, and curing. This not only results in long construction periods and significant weather-related impacts, but also generates a large amount of construction waste and dust, causing disturbance to the surrounding environment.

[0003] In existing technologies, the on-site assembly process of various components of inspection wells is complex, consuming manpower and time, and making it difficult to complete the installation quickly; the connections of components such as side walls, columns, and covers are not firm and are prone to loosening due to external forces or settlement, affecting the overall structural stability; the installation and disassembly of anti-fall nets are inconvenient, and subsequent maintenance and replacement are difficult, posing safety hazards; the versatility of inspection well components of different specifications is poor, making it difficult to flexibly adjust the structural dimensions according to actual needs.

The insertion hole 15 and the snap-fit ​​groove 11 are provided with a moving groove 16, a turning groove 17 and a pressing groove 18 that cooperate with the snap-fit ​​plate 13. The moving groove 16 and the pressing groove 18 are connected through the turning groove 17. A snap-fit ​​spring 19 is provided between the snap-fit ​​groove 11 and the snap-fit ​​block 12. A snap-fit ​​rod 20 is slidably provided on the snap-fit ​​sleeve 10. One end of the snap-fit ​​rod 20 is fixedly connected to the snap-fit ​​block 12, and the other end is provided with a snap-fit ​​handle 21. The mounting ring 8 includes a mounting plate 28. A mounting block 29 is provided on one side of the mounting plate 28, and a mounting groove 30 that cooperates with the mounting block 29 is provided on the other side. The mounting block 29 and the mounting groove 30 and the mounting plate 28 and the inspection tube 6 are all connected by bolts. The mounting ring 8 is provided on the mounting plate 28.

[0022] In this embodiment, when installing the fall arrestor net 9 on the inspection pipe 6, the mounting block 29 of the mounting plate 28 is sequentially attached to the mounting groove 30, and the mounting plates 28 are connected and fixed together with bolts. Then, the mounting plate 28 and the mounting ring 8 are installed on the inspection pipe 6 with bolts. When installing the fall arrestor net 9 through the snap-fit ​​device, the fall arrestor net 9 is sleeved on the snap-fit ​​sleeve 10, and the snap-fit ​​handle 21 is pulled outward. The snap-fit ​​handle 21 drives the snap-fit ​​block 12 and the snap-fit ​​plate 13 to move along the moving groove 16. By compressing the snap-fit ​​spring 19 through the snap-fit ​​block 12, after the snap-fit ​​plate 13 moves into the turning groove 17, the snap-fit ​​handle 21 is rotated, thereby driving the snap-fit ​​block 12 and the snap-fit ​​plate 13 to rotate 90 degrees, so that the snap-fit ​​plate 13 is aligned with the pressing groove 18. The snap-fit ​​handle 21 is released, and under the elastic force of the snap-fit ​​spring 19, the snap-fit ​​block 12 drives the snap-fit ​​plate 13 to move along the pressing groove 18, so that the insertion rod 14 is inserted into the insertion hole 15, fixing the position of the fall protection net 9 and improving the ease of installation.

[0024] More specifically, the base 2, side wall 3, column 4, and cover plate 5 are all prefabricated in the prefabrication yard. The side wall 3 is provided with connection holes for pipes that connect to the main body 1 of the inspection well. The position of the side wall 3 is adjusted as needed, and the column 4 is inserted into the support groove 27 so that the sliding block 22 of the side wall 3 and the sliding groove 23 of the column 4 cooperate and slide and lock together. The cooperation of the first locking block 25 and the second locking groove 31 connects the side wall 3 to the base 2. The cooperation of the first locking groove 24 and the second locking block 26 facilitates the connection between the cover plate 5 and the side wall 3. The cover plate 5 and the column 4, as well as the base 2 and the column 4, are connected and fixed by mounting bolts 7, thereby completing the assembly of the main body 1 of the inspection well.

[0025] In summary, during the use or operation of the overall equipment: When installing the fall protection net 9 on the inspection pipe 6, the mounting blocks 29 of the mounting plate 28 are sequentially attached to the mounting groove 30, and the mounting plates 28 are connected and fixed together with bolts. Then, the mounting plates 28 and the mounting ring 8 are installed on the inspection pipe 6 with bolts. When installing the fall protection net 9 through the snap-fit ​​device, the fall protection net 9 is placed on the snap-fit ​​sleeve 10, and the snap-fit ​​handle 21 is pulled outward.

The snap-fit ​​handle 21 is released, and under the elastic force of the snap-fit ​​spring 19, the snap-fit ​​block 12 drives the snap-fit ​​plate 13 to move along the pressing slot 18, so that the insertion rod 14 is inserted into the insertion hole 15, fixing the position of the fall protection net 9 and improving the ease of installation.

[0026] The base 2, side wall 3, column 4, and cover plate 5 are all prefabricated in the prefabrication yard. The side wall 3 is provided with connection holes for the pipes connected to the main body 1 of the inspection well. The position of the side wall 3 is adjusted as needed, and the column 4 is inserted into the support groove 27 so that the sliding block 22 of the side wall 3 and the sliding groove 23 of the column 4 cooperate and slide and lock. The cooperation of the first locking block 25 and the second locking groove 31 connects the side wall 3 to the base 2. The cooperation of the first locking groove 24 and the second locking block 26 facilitates the connection between the cover plate 5 and the side wall 3. The cover plate 5 and the column 4, as well as the base 2 and the column 4, are connected and fixed by mounting bolts 7, thereby completing the assembly of the main body 1 of the inspection well.
