Description

Noise-reducing rain inlet structure Technical Field The utility model relates to a silencing gully structure, and belongs to the technical field of pavement gullies. Background The rainwater grate, also called rainwater well lid, rainwater cover plate, rainwater ditch cover plate, is an open grid-shaped facility for covering the gully or drainage ditch. Its main function is to collect and drain rainwater, and prevent sundries such as leaves, garbage, etc. from entering sewer system, so as to prevent the drain pipeline from being blocked and ensure the smoothness of urban drain system. The utility model patent of the prior art with the publication number of CN218405749U comprises a gully body, a dirt-intercepting frame and a rain grate, wherein the gully body is provided with a lower-layer gully and an upper-layer gully, the lower-layer gully and the upper-layer gully are consistent in structure and are in butt joint through square flanges, the similar ends of the lower-layer gully and the upper-layer gully are respectively provided with a gully substrate, a pipeline connecting hole and a pipe orifice reinforcing rib, the inner side of the upper end of the gully substrate is provided with an anti-falling supporting groove, the pipeline connecting holes are provided with a plurality of anti-falling supporting grooves and distributed on the periphery of the gully substrate in four directions, the outer side of the pipeline connecting hole is provided with an annular sealing flange, a sealing rubber cushion is filled between the sealing flange and the pipeline connecting hole, and the pipe orifice reinforcing ribs are connected with the sealing flange and the upper end and the lower end of the gully substrate. The inventor finds that at least the following technical problems exist in the prior art: After long-time use, the passing vehicle is rolled, and friction collision is easy to generate between the base and the rainwater grate, so that noise pollution is generated. Disclosure of utility model The utility model aims to solve the technical problems of overcoming the defects of the prior art and providing the silencing gully structure which greatly reduces noise pollution. The utility model relates to a base for installation, which is provided with a rainwater grate, and a silencing gasket is arranged between the base and the rainwater grate and is made of elastic materials. Further, the silencing gasket comprises a lower supporting gasket and a side supporting gasket, and the lower supporting gasket is arranged between the upper end face used for supporting on the base and the lower end face of the rainwater grate; The side support gasket is arranged between the inner wall of the inner hole of the base and the outer wall of the rainwater grate. Further, at least one guiding inclined plane is arranged on the contact surface between the side support gasket and the outer wall of the rainwater grate or the inner wall of the inner hole of the base. Further, the lower end of the lower support gasket is also provided with a fixing strip, and the upper end surface of the base for supporting the rainwater grate is provided with a fixing groove matched with the fixing strip. Further, a height adjusting mechanism is arranged on the supporting plate extending outwards around the base. Further, the height adjustment mechanism includes a plurality of adjustment screws threadedly mounted to the support plate. Further, the elastic material of the sound attenuation gasket can be made of rubber materials, polyurethane materials or polymer composite materials. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, through the arrangement of the silencing gaskets, the friction collision between the rainwater grate and the base is effectively reduced, so that noise pollution is reduced. The setting of amortization gasket can also reduce the damage degree of rainwater grate and base, prolongs its life. Through the setting of high adjustment mechanism for the rainwater grate is better at installation levelness, through the height of adjustment base, can with the better of the distance difference control between the ground, avoided the wheel to cause the impact to the rainwater grate when passing through.
