[0003] In order to reduce the accumulation of water on the road surface, the through hole for launching water is usually arranged on the inspection well cover. Due to the depression of the through hole, the flatness is poor. When the vehicle passes above the inspection well cover, the vibration and noise are relatively large, which affects driving Comfort for people and pedestrians needs improvement

Embodiment Construction
[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0014] see figure 1 , the embodiment of the present invention includes:
[0015] A noise reduction manhole cover, comprising: a base base plate 1, a rubber ring 2 and a contact cover plate 3, the contact cover plate 3 is arranged in the rubber ring 2, and the rubber ring 2 is arranged in parallel above the base base plate 1 , the base base plate 1 is a circular plate, and the outer diameter of the base base plate 1 is the same as the outer diameter of the rubber ring 2, which is convenient to be combined and arrange...

The invention discloses a noise-reducing sewer well cover. The noise-reducing sewer well cover comprises a foundation base plate, a rubber ring and a contact cover plate, wherein the contact cover plate is arranged in the rubber ring; the rubber ring is arranged in parallel above the foundation base plate; micro holes penetrating up and down are densely formed in the contact cover plate; a circle of concave embedded grooves are formed in the inner side of the rubber ring; a circle of convex lip sides extending to the inside of the embedded grooves are arranged on the outer circle of the contact cover plate; a support gasket is arranged between the central position of the bottom surface of the contact cover plate and the upper surface of the foundation base plate. Through the manner, the micro holes are densely formed in the contact cover plate of the noise-reducing sewer well cover, so that the noise-reducing sewer well cover is excellent in draining capability; the hole diameter is small, so that the surface flatness is excellent; the vibration and the noise caused during driving of vehicles can be reduced; in addition, the rubber ring is capable of reducing vibration and noise, so that the overall noise-reducing performance is relatively excellent; meanwhile, due to the split structure, the noise-reducing sewer well cover is convenient to maintain and replace.
Description
technical field [0001] The invention relates to the field of municipal sewage engineering, in particular to a noise reduction inspection well cover. Background technique [0002] The use of inspection well cover is more extensive, is installed on the top of inspection well, all can see on street or square. The manhole cover is mainly for sewage discharge, cleaning and maintenance, and cannot be moved at will, and vehicles and pedestrians need to pass above it, so the structure requirements are relatively firm. [0003] In order to reduce the accumulation of water on the road surface, the through hole for launching water is usually arranged on the inspection well cover. Due to the depression of the through hole, the flatness is poor. When the vehicle passes above the inspection well cover, the vibration and noise are relatively large, which affects driving The comfort of personnel and pedestrians needs improvement. Contents of the invention [0004] The technical problem ...
