Description
Technical Field
[0001] This application relates to the technical field of municipal facilities, and particularly to a municipal inspection well. Background Art
[0002] Municipal inspection wells are key equipment in urban infrastructure for inspecting, maintaining, and repairing pipelines. Usually, an inspection well needs to be set at regular intervals to facilitate the maintenance and repair of pipeline facilities through the inspection well.
[0003] An inspection well generally includes a well seat, a wellbore, and a cover plate. The side wall of the wellbore is connected to the pipeline, and an installation groove is provided on the cover plate to install a cast iron manhole cover on the installation groove. When setting up existing inspection wells, in order to achieve better stability and strength, the inspection well is generally poured by the method of in-situ casting with a concrete formwork. For the inspection well poured in this way, it is necessary to wait for the inspection well to dry completely, which takes a long time; and for some inspection wells that require a long time, segmented pouring is also required, and the construction efficiency of the inspection well is low. Summary of the Utility Model

Card slots are formed on the outer side walls of the upper and lower ends of the splicing ring. When two splicing rings are spliced together, the adjacent two card slots are connected to form a slot body for the first half - ring and the second half - ring to be clamped, and the third connecting member can lock the first half - ring and the second half - ring in the card slot.
[0016] By adopting the above technical solution, through the design of the first half - ring, the second half - ring and the third connecting member, two splicing rings can be quickly fixed together; when two splicing rings are spliced together, the adjacent card slots are connected to form a slot body for the first half - ring and the second half - ring to be clamped, and then the first half - ring and the second half - ring are locked in the card slot by the third connecting member.

At the same time, the cooperation structure of the insertion ring 21 and the insertion slot 22 can improve the waterproof performance at the connection between the wellbore 2 and the base, and between the wellbore 2 and the cover plate 3.
[0033] Referring to Figure 1 and Figure 2, in this embodiment, for the convenience of transportation and installation, the wellbore 2 includes a plurality of splicing rings 25 spliced with each other and a fixing device 6 for fixing two adjacent splicing rings 25. Each splicing ring 25 is a precast concrete member, and a plug-in ring 21 is integrally formed on the upper surface of each splicing ring 25, and a plug-in groove 22 is precast on the lower surface. Thus, the plug-in rings 21 and the plug-in grooves 22 on two adjacent splicing rings 25 cooperate with each other. The plug-in groove 22 of the lowermost splicing ring 25 cooperates with the plug-in ring 21 on the well seat 1, and the plug-in ring 21 of the uppermost splicing ring 25 cooperates with the plug-in groove 22 on the cover plate 3.

[0037] Referring to Figure 2 and Figure 3, in this embodiment, in order to improve the waterproof property of the inspection well, an elastic pad 7 is provided between the upper surface of the insertion ring 21 and the inner bottom of the insertion slot 22. The elastic pad 7 is of an annular structure and is made of an elastic material such as rubber. When the insertion ring 21 is inserted into the insertion slot 22, the elastic pad 7 is pressed tightly between the insertion ring 21 and the inner bottom wall of the insertion slot 22, thereby being able to achieve a waterproof effect. The elastic pad 7 can be fixed on the upper surface of the insertion ring 21 or can be detachably arranged, and is fixed through the cooperation of the insertion ring 21 and the insertion slot 22 during on-site construction.

The first half-ring 61 and the second half-ring 62 can be made of metal to ensure the strength of the first half-ring 61 and the second half-ring 62. A card slot 251 is formed on the outer side wall of the splicing ring 25. The card slot 251 is respectively formed at the upper and lower ends of the splicing ring 25, and the card slot 251 respectively penetrates through the upper and lower end faces of the splicing ring 25. When two adjacent splicing rings 25 are spliced with each other, the card slots 251 of the two splicing rings 25 are connected to form a slot body for the first half-ring 61 and the second half-ring 62 to be clamped. The two first half-rings 61 and the second half-ring 62 are symmetrically clamped into the card slot 251, so that the inner walls of the first half-ring 61 and the second half-ring 62 are pressed tightly against the two splicing rings 25, thereby being able to fix two adjacent splicing rings 25 through the frictional force between them.
[0039] Refer to Figure 1 and Figure 4 , in this embodiment, the third connecting member 8 can be a third bolt 81 and a third nut 82. Connecting blocks 63 are respectively fixed at both ends of the first half-ring 61 and the second half-ring 62. When the first half-ring 61 and the second half-ring 62 are both clamped into the card slot 251, the third bolt 81 can sequentially pass through two adjacent connecting blocks 63 on the first half-ring 61 and the second half-ring 62, and the two connecting blocks 63 are locked through the third nut 82. In order to improve the waterproof effect at the connection of the first half-ring 61 and the second half-ring 62, first teeth 611 are respectively fixed on the end faces of the first half-ring 61, and second teeth 621 are fixed on the end faces of the second half-ring 62. The first teeth 611 and the second teeth 621 are both distributed along the diameter direction of the cylinder body. When the first half-ring 61 and the second half-ring 62 are connected to each other, the first teeth 611 and the second teeth 621 can be inserted into each other.
[0040] Refer to Figure 3 and Figure 4, in this embodiment, limiting rings 64 are fixedly arranged on the inner side walls of the first half-ring 61 and the second half-ring 62. Two limiting rings 64 are respectively arranged at intervals on the first half-ring 61 and the second half-ring 62 along the axial direction of the wellbore 2. Correspondingly, limiting slots 252 for inserting the limiting rings 64 are formed at the upper and lower ends of the splicing ring 25. The limiting slots 252 communicate with the clamping slots 251. Thus, when two splicing rings 25 are connected and the first half-ring 61 and the second half-ring 62 are inserted into the clamping slots 251, the limiting rings 64 on the first half-ring 61 and the second half-ring 62 can be respectively inserted into the limiting slots 252 of two adjacent splicing rings 25, thereby increasing the connection strength between two adjacent splicing rings 25.
