Description

Technical Field

[0001] This application relates to the field of municipal facilities, and particularly to a highly stable municipal manhole cover. Background Art

[0002] There are many underground pipelines in urban construction, such as sewer pipelines, underground gas pipelines, tap water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. There should be an exit leading to the ground at regular intervals for these pipelines. The section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground. Therefore, a lid is needed to cover the manhole, and this lid is called a manhole cover.

[0003] Generally, when installing a manhole cover, the manhole base is first installed at the manhole opening on the road surface. After the manhole base is fixed, the manhole cover is then placed on the manhole base to close the manhole opening. After a period of use of the manhole cover, the manhole base will settle, resulting in a height difference between the top surface of the manhole cover and the road surface that exceeds the allowable range, and the road surface around the manhole base will be damaged, making the vehicle bumpy when passing by, which needs to be improved.

[0032] The following will further describe the present application in detail with reference to Figures 1-4 the accompanying drawings.

[0033] An embodiment of the present application discloses a highly stable municipal manhole cover. Referring to Figure 1 and Figure 2 , the highly stable municipal manhole cover includes a road main body 1 and a manhole cover assembly 2 installed on the road main body 1. A wellhead 3 is formed on the road main body 1, and an installation opening 4 is formed on the wellhead 3. The installation opening 4 is located at the top of the wellhead 3.

[0034] Referring to Figure 2 and Figure 3 , the manhole cover assembly 2 includes a bottom ring 21, a manhole seat 22 and a cover body 23. The bottom ring 21 is fixed to the bottom wall of the installation opening 4, the manhole seat 22 is fixed on the bottom ring 21, and an insertion slot 5 is formed at the bottom of the manhole seat 22. The insertion slot 5 is for the top of the bottom ring 21 to be inserted so that the manhole seat 22 is installed and fixed on the bottom ring 21. The cover body 23 covers the manhole seat 22, and the top surface of the manhole seat 22 is flush with the road surface of the road main body 1. An asphalt layer 6 (refer to Figure 1 ) is laid at the installation opening 4. The asphalt layer 6 is used to fix the bottom ring 21 and the manhole seat 22 in the installation opening 4. A shock-absorbing ring 7 is installed in the installation opening 4. The shock-absorbing ring 7 (refer to Figure 1 ) is located between the outer wall of the asphalt layer 6 and the side wall of the installation opening 4.

[0035] Referring to Figure 2 and Figure 3 , an installation groove 8 is formed on the bottom wall of the installation opening 4. The installation groove 8 is for the bottom ring 21 to be received. A positioning protrusion 9 is fixed on the bottom ring 21. The positioning protrusion 9 is located at the bottom of the bottom ring 21. A positioning groove 10 is formed on the side wall of the installation groove 8. The positioning groove 10 is for the positioning protrusion 9 to be received. A placement protrusion 11 is integrally fixed on the manhole seat 22. The placement protrusion is for the cover body 23 to abut against so that the cover body 23 is installed on the manhole seat 22. A rubber pad 12 is installed on the placement protrusion 11. The top surface of the rubber pad 12 abuts against the cover body 23. An inlay protrusion 13 is fixed to the bottom of the rubber pad 12. An inlay groove 14 for the inlay protrusion 13 to be received is formed on the placement protrusion 11.
