Problems solved by technology
[0002] In urban construction, due to the underground laying of various municipal facilities such as communication cables, gas pipelines, and sewage pipes, it is often necessary to set manhole covers on the road surface to facilitate engineering personnel to remove the covers and maintain various underground facilities; When the load is applied, the manhole cover will be slightly curved and deformed, and when the load leaves, it will rebound, which will cause the manhole cover to collide with the concrete structure; this collision often produces noise, directly disturbing the lives of nearby residents

Embodiment Construction
[0019] The present invention will be further explained below in conjunction with the drawings.
[0020] Such as Figure 1 to 5 As shown, the mute structure for laying a municipal manhole cover according to the present invention includes a manhole cover body 1 and a pavement concrete structure 4; the bottom surface of the manhole cover body 1 is provided with a cover body positioning vertebra 103; The cover positioning vertebra 103 is in the shape of an inverted cone; the pavement concrete structure 4 is provided with a concrete structure positioning cone 401 that matches the cover positioning vertebra 103; the outer wall of the cover positioning vertebra 103 is attached Fitted on the positioning cone surface 401 of the concrete structure; the inside of the manhole cover 1 is provided with several lateral positioning structures; the lateral positioning structure is composed of bolts 2 and inner braces 3; the inner braces 3 are pre-embedded Fixed inside the manhole cover body 1; t...

The invention relates to the technical field of paving structures of manhole covers, in particular to a paving silencing structure for a municipal manhole cover. The outer side wall of a cover body positioning cone is attached to the concrete structure positioning conical surface; a plurality of lateral positioning structures are arranged in the manhole cover body; the lateral positioning structures are composed of bolts and inner tooth sleeves; the inner tooth sleeves are pre-buried and fixed into the manhole cover body; the bolts are in threaded connection with the inner tooth sleeves; one ends of the bolts are pressed on the concrete structure positioning conical surface in an abutting mode; and the heads of the bolts are arranged in inner cavities of all grooves correspondingly. When the paving silencing structure is used, the manhole cover body is positioned in the planar direction on the concrete structure positioning conical surface through the cover body positioning cone and then locked and fixed through the bolts; through static friction force generated when the bolts are tightly pressed on the concrete structure positioning conical surface, the manhole cover body is fixed onto a road surface concrete structure, and thus the manhole cover body is prevented from generating noise; and the living environments of surrounding residents are improved to a great limit.
Description
Technical field [0001] The invention relates to the technical field of paving structures for manhole covers, in particular to a mute structure for paving municipal manhole covers. Background technique [0002] In urban construction, due to the laying of various municipal facilities such as communication cables, gas pipelines, sewage pipes, etc., it is often necessary to set up manhole covers on the horse pavement to facilitate engineers to uncover and repair various underground facilities; traditional manhole covers are used as When subjected to a load, the manhole cover will be slightly bent and deformed. When the load is removed, it will rebound, which will cause the manhole cover to collide with the concrete structure; this collision often produces noise and directly disturbs the lives of nearby residents. [0003] Therefore, it is necessary to make further technical innovations to the existing manhole cover laying structure. Summary of the invention [0004] The purpose of the ...
