Sound insulation protection baffle for road construction

Abstract

The invention discloses a sound insulation protection baffle for road construction. The sound protection baffle comprises a plurality of mounting frames, mounting pads are arranged at the bottoms of the mounting frames, and mounting screw holes are formed in the two ends of the surface of each mounting pad; baffle bodies are arranged between every two adjacent fixing frames, and a sound insulationcavity is formed in each baffle body; sound absorption cotton is arranged on the two sides of the inner wall of each sound insulation cavity. According to the baffle, the fixing frames are clamped tothe baffle bodies, bolts penetrate through the mounting screw holes in the mounting pads, and the bolts are fixedly connected with the ground, so that installation of the protection baffle is facilitated; the sound insulation cavities in the baffle bodies are matched with the two layers of sound absorption cotton, so that noise is isolated and adsorbed, noise transmission is effectively reduced,and the sound insulation effect is achieved; water is conveyed through a water guide pipe, and atomized water is sprayed out through a water mist nozzle, so that dust generated by construction is sprayed and adsorbed, spreading of the dust is reduced, the functionality of the protection baffle is improved, and the use of the protection baffle is facilitated.

Description

technical field [0001] The invention relates to the technical field of protective baffles, in particular to a sound-proof protective baffle for road construction. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's living standards, on the one hand, the mileage of highways continues to increase, and the road grades continue to increase. On the other hand, the number of cars is increasing. Therefore, the expansion of traffic roads is active. The noise prediction model predicts road traffic noise, and on the basis of the prediction results, determines the prevention and control countermeasures and carries out noise reduction engineering design according to the nature, location, scale, local conditions and engineering characteristics of sensitive points, which has become a road traffic environmental protection work. It is of great significance to urban transportation, architectural planning and noise pollution prev...

AI Technical Summary

Problems solved by technology

However, the existing protective plate has a simple structure and poor sound insulation effect. The traditional road and bridge sound reduction devices used in municipal bridge projects are very inconvenient to install, and the dust generated during the construction process is relatively large, which is easy to pollute the environment.
