Description

Technical Field

[0001] The present application relates to the technical field of manholes, and in particular to a municipal road manhole structure. Background Art

[0002] At present, manholes are an important part of urban underground pipelines, used to transfer and control various underground pipelines, such as water supply, sewage, telephone lines, optical fiber networks, etc. Manholes allow maintenance personnel to easily enter the pipelines and inspect, repair and install the pipelines in the pipelines, thereby ensuring the normal operation of urban infrastructure.

[0003] The existing manhole structure mainly includes a mounting seat and a manhole cover for covering the manhole opening of the mounting seat. Due to the existence of the manhole opening, the load-bearing area between the mounting seat and the manhole cover is relatively small. Therefore, when the manhole cover is subjected to a large external force, the central part of the manhole cover is prone to breakage or even fracture, thus posing a great safety hazard.

DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The embodiment of the present application discloses a municipal road manhole structure.

[0025] Reference Figure 1 , Figure 2 as well as Figure 3 The municipal road manhole structure includes a mounting seat 1 for fixed installation on the outside of the sewage pipe, and a manhole cover 2 for covering the manhole of the mounting seat 1. A circumferentially arranged mounting groove 11 is arranged on the top side wall of the mounting seat 1 facing the manhole cover 2, and the central axis of the mounting groove 11 is coaxially arranged with the central axis of the manhole of the mounting seat 1. A mounting frame 22 for inserting into the mounting groove 11 from top to bottom is fixedly arranged on the bottom side wall of the manhole cover 2 facing the mounting groove 11, and the manhole cover 2 is fixed to the top of the mounting seat 1 by the mutual plug-in cooperation between the mounting frame 22 and the mounting groove 11.

[0026] like Figure 3 , Figure 4 As shown, a plurality of push rods 110 are fixedly mounted on the side wall of the mounting groove 11 facing the manhole cover 2. The push rods 110 are evenly spaced around the manhole in the circumferential direction. A rubber pad 111 is fixedly bonded on the side wall of the push rod 110 facing the manhole cover 2. The rubber pad 111 is used to fit and contact the bottom wall of the manhole cover 2. The rubber pad 111 can provide a buffering and shock-absorbing effect on the manhole cover 2 when the manhole cover 2 vibrates.

[0027] like Figure 3 , Figure 4 As shown, the bottom of the mounting seat 1 is coaxially fixed with an extension seat 3, and a support plate 30 is fixedly installed on the inner side wall of the extension seat 3 and arranged obliquely downward. The support plate 30 is penetrated by a plurality of drainage holes 31 arranged in sequence, and the outer side wall of the extension seat 3 is provided with a discharge port 35 for the garbage falling on the support plate 30 to be discharged from the extension seat 3.

[0028] like Figure 3 , Figure 4 As shown, the discharge port 35 is interconnected with the interior of the extension seat 3. By aligning the discharge port 35 with the solid waste collection pipe pre-buried in the ground, the sewage flowing down from the wellhead can be smoothly discharged into the sewage pipe below through the drainage hole 31. The support plate 30 can also block the larger fixed garbage carried in the sewage, so as to achieve screening of the fixed garbage and the sewage. The inclined support plate 30 can help the solid garbage fall from the support plate 30 into the external solid waste collection pipe, and the solid garbage can be uniformly collected through the solid waste collection pipe, thereby effectively alleviating the problem of the sewage pipe being blocked by fixed garbage.

[0029] like Figure 3 , Figure 4 As shown, a support plug 32 is fixedly installed on the side wall of the support plate 30 facing the manhole cover 2, and a vertically placed support rod 33 is inserted and fixed in the support plug 32, and the top of the support rod 33 gradually extends in the direction close to the upper manhole cover 2. A limiting groove 20 is integrally formed on the side wall of the manhole cover 2 facing the support rod 33, and a support plate 34 is fixedly installed on the top of the support rod 33. The shape of the support plate 34 is adapted to the shape of the limiting groove 20, and the support plate 34 is used to be inserted from bottom to top and limited in the limiting groove 20. The support plate 34 inserted into the limiting groove 20 is mutually attached and abutted against the bottom wall of the manhole cover 2. At this time, the manhole cover 2 can be supported under the action of the support rod 33, thereby further enhancing the stability and reliability of the manhole cover 2 installed outside the mounting seat 1. Through the mutual plug-in cooperation between the support plate 34 and the limiting groove 20, the stability of the support rod 33 when supporting can be ensured.

[0030] like Figure 3 , Figure 4 As shown, a plurality of reinforcing strips 21 are integrally formed on the bottom side wall of the manhole cover 2 facing the extension seat 3. The length of the reinforcing strips 21 extends radially along the manhole cover 2, and the reinforcing strips 21 are circumferentially arranged around the limiting grooves 20 in sequence. The reinforcing strips 21 further enhance the overall structural strength of the manhole cover 2, thereby further improving the load-bearing capacity of the manhole cover 2.

[0031] like Figure 3 , Figure 4 As shown, a plurality of plug-in columns 10 are fixedly mounted on the outer wall of the mounting seat 1. The length of the plug-in columns 10 extends along the depth direction of the wellhead, and each plug-in column 10 is circumferentially spaced and arranged around the wellhead. When installing the mounting seat 1, the plug-in columns 10 are aligned with the openings preset on the road surface, and then the plug-in columns 10 are inserted from top to bottom into the respective openings. Through the mutual plug-in cooperation of the plug-in columns 10 and the openings, the mounting seat 1 can be initially limited and fixed on the road surface, which prevents the rotation of the mounting seat 1, ensures the stability of the mounting seat 1, and facilitates the subsequent further construction.

[0032] The implementation principle is: when the manhole cover 2 is installed outside the wellhead of the mounting seat 1, the manhole cover 2 can be supported under the action of the support rod 33, so that the supporting area of ​​the mounting seat 1 on the manhole cover 2 can be further increased, the bearing area of ​​the manhole cover 2 is expanded, and the supporting effect on the manhole cover 2 is improved, so that the manhole cover 2 can be more stably and securely installed on the mounting seat 1, reducing the safety hazards of the manhole cover 2. In addition, the sewage flowing down from the wellhead can be smoothly discharged into the sewage pipe below through the drainage hole 31, and the fixed garbage carried in the sewage can be blocked by the support plate 30, so that the fixed garbage and sewage can be screened, thereby effectively alleviating the situation where the sewage pipe is blocked by the fixed garbage.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
