[0002] Currently, municipal road construction projects face difficulties in constructing around various manholes, including those for water supply, rainwater, and sewage. Insufficient compaction and easy settlement lead to cracking and collapse around the manhole rings, and the manhole covers are easily damaged, severely impacting vehicle and pedestrian safety. Existing technologies using traditional installation methods result in insufficient compaction of the surrounding concrete, uneven foundation settlement causing road surface cracking, and difficulty in adjusting manhole cover height due to unsuitable road surface height, all of which affect road quality and smoothness.

[0003] A patent search revealed a patent, publication number "CN212336101U," entitled "An Adjustable Anti-Settlement Inspection Well Structure." While the device in this publication addresses the aforementioned problem, it fails to support the central area of ​​the manhole cover. Under prolonged external pressure, the central area of ​​the cover is prone to deformation, reducing its overall strength and thus the anti-settlement effect. Therefore, this invention designs an anti-settlement inspection well structure to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] A preferred embodiment of the anti-settlement inspection well structure provided by this utility model is, for example... Figures 1 to 5 As shown: A settlement prevention inspection well structure includes an asphalt pavement 1, a well cylinder 2 fixed in the middle of the asphalt pavement 1; a placement groove 3 integrally set in the top of the well cylinder 2, and a well cover 4 is set in the placement groove 3; brackets 5 fixed in the left and right sides of the well cylinder 2; connecting rods 6 fixed in the four corners of the bottom of the well cover 4, and mounting rings 7 fixed in the bottom of the connecting rods 6; and a limiting component 8 assembled in the well cover 4, which can support the central area of ​​the well cover 4.

[0029] The limiting assembly 8 includes a support rod 801 rotatably disposed inside the middle of the manhole cover 4; and top rods 802 disposed on the left and right sides outside the support rod 801. The top rods 802 rotatably pass through the mounting ring 7. The support rod 801 and the top rods 802 are perpendicular to each other. The mounting ring 7 is rotatably sleeved on the outside of the support rod 801.

[0030] It should be noted that the existing anti-settlement inspection well structure still has certain shortcomings in actual use. It cannot support the central area of ​​the manhole cover, which leads to deformation of the manhole cover after long-term use, affecting the overall strength of the manhole cover and reducing the anti-settlement effect of the inspection well.

[0031] In this embodiment, the worker first places the manhole cover 4 into the placement slot 3, so that the manhole cover 4 moves the connecting rod 6 together with the mounting ring 7 and the top rod 802 into the inside of the manhole 2. In this way, the top rod 802 is inserted into the inside of the bracket 5. At this time, the bracket 5 supports the top rod 802, so that the top rod 802 moves the mounting ring 7 together with the connecting rod 6 and the support rod 801 to support the central area of ​​the manhole cover 4.

[0032] In a further preferred embodiment of the present invention, a guide component 9 is assembled on the outside of the manhole cover 4. The guide component 9 can guide the manhole cover 4 into the placement groove 3. The guide component 9 includes a guide rod 901 fixed at the front and rear ends of the bottom of the manhole cover 4; and a guide hole 902 provided at the lower end of the guide rod 901. The guide hole 902 is integrally connected to the manhole 2.

[0033] In this embodiment, when the manhole cover 4 is placed inside the placement slot 3, the worker first overlaps the guide rod 901 with the guide hole 902 so that the guide rod 901 is inserted into the guide hole 902. The purpose is to ensure the stability of the top rod 802 and the support 5 during the process of placing the top rod 802 into the manhole 2.

[0034] Example 2

[0035] Based on Embodiment 1, a preferred embodiment of the anti-settlement inspection well structure provided by this utility model is, for example... Figures 1 to 5As shown: The support rod 801 has an integrally formed insertion hole 10, which is a through hole. The cross-section of the insertion hole 10 is square when viewed from above. The support rod 801 and the connecting rod 6 are designed to be parallel to each other. The diameter of the support rod 801 is larger than the diameter of the connecting rod 6. The top rod 802 is externally threaded with a limiting rod 12. The limiting rod 12 has an L-shaped cross-section and is slidably connected to the well cover 4. Limiting holes 13 are integrally formed on the left and right sides of the lower end of the well shaft 2. The limiting holes 13 are through holes and are connected to the limiting rod 4. The positioning rod 12 is disassembled and assembled by plugging in. The support rod 801 is equipped with a drive assembly on its outside. The drive assembly can control the top rod 802 to rotate. The drive assembly includes an active bevel tooth 14 fixedly sleeved on the lower end of the support rod 801; and driven bevel teeth 15 with gear meshing design on the left and right sides outside the active bevel tooth 14. The driven bevel teeth 15 are fixedly sleeved on the outside of the top rod 802. The manhole cover 4 has a connecting hole 16 integrally provided on the front and rear sides inside. The connecting hole 16 is equipped with a detachable E-type plate 17.

[0036] In this embodiment, after the top rod 802 is inserted into the bracket 5, the operator inserts the square handle into the insertion hole 10, and then rotates the support rod 801 clockwise. The support rod 801 drives the active bevel gear 14 to rotate in conjunction with the driven bevel gear 15, along with the top rod 802. Through the threaded transmission design of the top rod 802 and the limiting rod 12, the limiting rod 12 moves along the outer direction of the manhole cover 4, thereby allowing the limiting rod 12 to be inserted into the limiting hole 13. In this way, not only is the state of the manhole cover 4 and the manhole 2 combined locked, but the strength of the support provided by the top rod 802, the connecting rod 6, and the support rod 801 to the central area of ​​the manhole cover 4 is also improved. The operator then inserts the E-shaped plate 17 into the connecting hole 16, and the E-shaped plate 17 is simultaneously inserted into the insertion hole 10, thereby locking the angle of the support rod 801 after rotation.

[0037] In summary, this application utilizes a plug-in support design, allowing the bracket to support the top rod, which in turn drives the support rod to support the central area of ​​the manhole cover, thus improving the strength of the manhole cover under stress and enhancing the anti-settlement effect of the inspection well. Through a mechanical linkage design, the limiting rod can be inserted into the limiting hole, ensuring not only the stability of the connection between the manhole cover and the well casing but also increasing the strength of the support rod's support for the manhole cover. Furthermore, the locking function design allows the angle of the rotating support rod to be locked, ensuring the stability of the limiting rod inserted into the limiting hole.
