Abstract

The application provides a noise reduction cement board structure for temporary protection of a road surface, and relates to the field of temporary protection of the road surface. Including the cement board main part, a plurality of first noise reduction holes have all been evenly seted up to the equal symmetry in both sides of cement board main part, and the equal fixedly connected with abatvoix of the equal fixedly connected with in inner wall in hole of making an uproar falls, and the equal symmetry in both sides below of cement board main part has been seted up the hole of making an uproar of second. This a cement plate structure of making an uproar falls for temporary protection on road surface when the vehicle passes through the cement plate main part, the buffering slope that a plurality of buffer blocks are constituteed reduces the vehicle and rocks through its production, reduce the noise that its produced, the noise that produces on cement plate main part upper portion is absorbed through the acoustic board in the first noise reduction hole, the noise that produces because of rocking in passing through the spout with cement plate main part below through the second noise reduction hole conveys the notch, fix the cement plate main part in the inside of notch through fixed subassembly, increase its stability, the rocking that produces when reducing the vehicle and pass through, noise that produces when reducing the cement plate use, noise pollution is reduced.

Description

Noise reduction cement board structure for temporary protection of pavement Technical Field The application relates to the technical field of temporary protection of pavements, in particular to a noise reduction cement board structure for temporary protection of pavements. Background In the engineering construction process, the road can be called a life line, municipal pipe networks are intricate and complex at the bottom of the road, and the embedding depth can also be called different depths. Various construction vehicles will come in the engineering construction process, and certain damages are carried out on road surfaces and municipal pipe networks, so that the road needs to be repaired and maintained at random, the road needs to be broken after repair and maintenance, and pipelines in the road are exposed, namely the original road is grooved. For some constructions with longer period, in order to ensure normal traffic of the original road and normal construction of engineering, cement plates can be temporarily paved on a construction site to shield the grooving positions so that the travelling crane passes through, and meanwhile, the cement plates play a role in protecting municipal roads and pipelines, so that the road and the pipeline are prevented from being damaged. However, in urban construction, there are many residential communities, schools, units, enterprises and the like on two sides of the road, and the noise generated when the vehicle passes through the cement board is large, and especially the noise generated at night can seriously affect the normal rest of people around, so that a noise reduction cement board structure for temporary protection of the road surface is needed. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the application provides a noise reduction cement board structure for temporary protection of a pavement, and solves the problems in the background art. (II) technical scheme The noise reduction cement board structure for temporary pavement protection comprises a cement board main body, wherein a plurality of first noise reduction holes are symmetrically and uniformly formed in two sides of the cement board main body, the inner walls of the first noise reduction holes are fixedly connected with a sound absorbing board, second noise reduction holes are symmetrically formed in the lower sides of the two sides of the cement board main body, a sliding groove is formed in the lower surface of the cement board main body, the second noise reduction holes are communicated with the sliding groove, a fixing assembly used for fixing the cement board main body in a pavement notch is arranged in the sliding groove, and a plurality of buffer blocks are symmetrically and uniformly connected to two sides of the cement board main body. Through adopting above-mentioned technical scheme, when the vehicle passes through the cement board main part, the buffering slope of constituteing through a plurality of buffer blocks reduces the vehicle and rocks through its production, thereby reduce the noise that its produced, the noise that produces on cement board main part upper portion is absorbed through the acoustic board of first downthehole noise reduction, the noise that produces because of rocking with cement board main part below through the second noise reduction hole passes through the spout and conveys in the notch, fix the cement board main part in the inside of notch through fixed subassembly, increase its stability, the rocking of production when reducing the vehicle and pass through, the noise that produces when comprehensively reducing the cement board use, noise pollution has been reduced.
