Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a rapid installation device for road manhole covers. Background Technology

[0002] Existing technology involves pre-reserving a filling ring around the manhole opening before installing the manhole cover. A concrete layer is then laid at the bottom of this ring until it is flush with the manhole opening. After this, a retaining ring is inserted into the opening to reserve space for the manhole cover and base. Once the retaining ring is inserted, asphalt is laid in layers around it and compacted until it is roughly flush with the road surface. After the asphalt dries, the retaining ring is removed, and the manhole cover and base are vertically placed into the asphalt groove formed by the retaining ring, and finally compacted. However, this installation process is cumbersome and inefficient. Furthermore, the retaining ring adheres firmly to the asphalt, making removal difficult and potentially damaging the formed asphalt groove. Therefore, a simple and quick manhole cover installation device is needed. Utility Model Content

[0003] The purpose of this utility model is to provide a quick installation device for road manhole covers, which has the advantages of simple and quick installation and solves the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A quick-installation device for road manhole covers includes a manhole opening, a filling ring area on the outer side of the manhole opening, a socket ring embedded at the top of the manhole opening, and a truncated cone base that is narrower at the top and wider at the bottom fixed to the upper part of the socket ring. The truncated cone base is located on the outer periphery of the socket ring and coaxially connected to it. The truncated cone base includes a flat ring plate and an inclined ring plate. The inner wall of the flat ring plate is connected to the outer wall of the socket ring, the top of the inclined ring plate is connected to the top surface of the socket ring, and the bottom of the inclined ring plate is connected to the outer wall of the flat ring plate. A limiting ring for supporting the manhole cover is provided on the upper part of the inner wall of the socket ring.

[0006] Preferably, the lower part of the filling ring area is filled with a concrete layer, and the upper part is filled with an asphalt layer.

[0007] Preferably, the lower part of the socket ring is inserted into the wellhead and fits against the inner wall of the wellhead.

[0008] Preferably, a hollow groove is formed between the planar ring plate, the inclined ring plate, and the socket ring.

[0009] Preferably, the hollow groove is provided with reinforcing ribs, and there are a number of reinforcing ribs that are evenly distributed circumferentially.

[0010] Preferably, the reinforcing rib is a vertically arranged triangular iron plate with its edges welded to the inner walls of the planar ring plate, the inclined ring plate, and the socket ring, respectively.

[0011] Preferably, the planar annular plate abuts against the top surface of the wellhead.

[0012] Preferably, the outer diameter of the planar annular plate is equal to the outer diameter of the wellhead.

[0013] Preferably, one side of the manhole cover is rotatably connected to a hinge seat provided on the inclined ring plate via a rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] During installation, the socket ring is inserted into the inner wall of the manhole until the flat ring plate abuts against the top surface of the manhole. Then, asphalt is laid in layers and compacted in the filling ring area, i.e., the outer perimeter of the inclined ring plate, until the asphalt is flush with the original asphalt pavement. Because the inclined ring plate has a structure that is wider at the bottom and narrower at the top, the socket ring and the truncated cone are not easily detached from the asphalt after the asphalt dries. They remain in the manhole as a permanent support structure, eliminating the step of pulling out the limiting manhole ring in the traditional method, avoiding damage to the asphalt groove, and simplifying the construction process, making it convenient and quick.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the cumbersome and labor-intensive installation of manhole covers in existing technologies, the following technical solution is proposed. Please refer to [link / reference]. Figure 1-5 ;

[0024] The road manhole cover quick installation device includes a manhole opening 1, which is located in a filling ring area 2. A concrete layer 3 has been laid in the filling ring area 2 to enhance the road surface strength. A socket ring 4 is installed in the manhole opening 1. The lower part of the socket ring 4 passes into the manhole opening 1 and fits against the inner wall of the manhole opening 1. A truncated cone base 5, which is narrower at the top and wider at the bottom, is fixed to the upper part of the socket ring 4. The truncated cone base 5 is located on the outer periphery of the socket ring 4 and is coaxially connected to it.

[0025] The truncated cone base 5 is a hollow structure. The truncated cone base 5 includes a flat ring plate 8 and an inclined ring plate 9. The inner wall of the flat ring plate 8 is connected to the outer wall of the socket ring 4. The top of the inclined ring plate 9 is connected to the top surface of the socket ring 4. The bottom of the inclined ring plate 9 is connected to the outer wall of the flat ring plate 8.

[0026] A hollow groove 6 is formed between the flat ring plate 8, the inclined ring plate 9, and the socket ring 4. A reinforcing rib 7 is provided in the hollow groove 6. The reinforcing rib 7 is a triangular iron plate that is set vertically and whose edges are welded to the inner walls of the flat ring plate 8, the inclined ring plate 9, and the socket ring 4 respectively. There are a number of reinforcing ribs 7 and they are evenly distributed in the circumference to enhance the bearing capacity of the inclined ring plate 9.

[0027] The flat ring plate 8 abuts against the top surface of the wellhead 1. The outer diameter of the flat ring plate 8 is equal to the outer diameter of the wellhead 1, which makes it easy for construction personnel to lay asphalt in layers outside the wellhead 1 and prevents the formation of filling dead corners.

[0028] The upper part of the inner wall of the socket ring 4 is provided with a limiting ring 10 for supporting the manhole cover 11. The top surface of the manhole cover 11 is flush with the top surface of the socket ring 4. One side of the manhole cover 11 is rotatably connected to the hinge seat 13 provided on the inclined ring plate 9 through the rotating shaft 12.

[0029] Working principle: Insert the socket ring 4 into the inner wall of the manhole 1 until the flat ring plate 8 abuts against the top surface of the manhole 1. Then, lay asphalt in layers and compact it in the filling ring area 2, i.e., the outer perimeter of the inclined ring plate 9, until the asphalt is flush with the original asphalt pavement 14. Since the inclined ring plate 9 has a structure that is wider at the bottom and narrower at the top, the socket ring 4 and the truncated cone 5 are not easy to fall out of the asphalt after the asphalt dries. They are retained in the manhole 1 as a permanent support structure, eliminating the step of pulling out the limiting manhole ring in the traditional method, avoiding damage to the asphalt groove, and simplifying the construction process.
