Description
Technical field
The utility model relates to a kind of noise reduction device technical field, particularly relates to a kind of road and bridge noise reduction device.
Background technology
Along with present expanding economy and people, the requirement to trip condition constantly improves, road and bridge are repaiied more and more, and road and bridge are that noise produces comparatively intensive place, with looking for people to the requirement of quality of the life, if the noise problem that can not effectively suppress road and bridge to produce will have a strong impact on the quality of the life of people, noise pollution will become problem very important in modernization construction.
Summary of the invention
The purpose of this utility model is just to provide a kind of road and bridge noise reduction device to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of road and bridge noise reduction device, comprise substrate, insulation material layer, snake bend, acoustical lining, gas vent, cellular board and gas access, described substrate inwall is provided with insulation material layer, described substrate inside is provided with horizontal acoustical lining, and described acoustical lining offers breach, described acoustical lining upper and lower side is provided with snake bend, described snake bend offers through hole, the upper end of described substrate is provided with gas vent on the right side, the side that keeps left, the lower end of described substrate is provided with gas access.
Further, described insulation material layer is acoustical cotton.
Further, on described snake bend, hole size shape is different.
Further, described acoustical lining is provided with multiple.
Further, described acoustical lining offers Kou Chu and be provided with cellular board.
The beneficial effects of the utility model are: this utility model adopts multiple noise reduction measure, the measure of many spaces noise reduction gradually, make noise reduction more remarkable, by constantly upset sound wave the direction of motion and make sound wave at the volley energy constantly offset and weaken, effectively reduce the intensity of noise.
