A vulcanized rubber soundproof manhole cover

By designing a vulcanized rubber sound insulation manhole cover, the side edges of the manhole cover body are sealed and connected by three sides of the elastic sound insulation coil, which solves the problem that the existing manhole cover structure is prone to collision noise and the sound insulation bars are easily fallen off, achieving better silent effect and stability of the sound insulation bars.

AI Technical Summary

Technical Problem

The existing manhole cover structure is prone to metal collision noise with the inner side of the well seat when it is shaking, and the sound insulation strips are prone to fall off.

Method used

A vulcanized rubber sound insulation manhole cover is designed. The side edges of the manhole cover body are sealed and connected on three sides by elastic sound insulation coils to ensure that the sound insulation coil is difficult to fall off, and are spaced from the well seat through elastic sound insulation coils to avoid metal collision noise.

Benefits of technology

It significantly improves the silence effect of the manhole cover, prevents collision noise from occurring with the inner side of the well seat when the manhole cover body shakes, and improves the stability of the sound insulation strips.

Abstract

The present application relates to the technical field of manhole cover structures, and provides a vulcanized rubber soundproof manhole cover, wherein the vulcanized rubber soundproof manhole cover comprises a manhole cover body, an elastic soundproof ring and a manhole seat; an embedding groove is provided on the inner side of the elastic soundproof ring, and the elastic soundproof ring covers the side edge of the manhole cover body in the embedding groove, and the upper surface, lower surface and side surface of the side edge of the manhole cover body are all sealed with the groove surface of the embedding groove, the manhole cover body is detachably mounted on the manhole seat, the elastic soundproof ring is in sealing contact with the manhole cover and the manhole seat, and the manhole cover body is spaced from the manhole seat by the elastic soundproof ring. The vulcanized rubber soundproof manhole cover can solve the problem of collision noise easily generated by the manhole cover structure in the prior art.
