A bridge sound insulation structure for municipal engineering

Abstract

The invention discloses a bridge sound insulation structure for municipal engineering, which comprises concrete guardrails, the concrete guardrails are symmetrically arranged on both sides of the bridge road surface, the top of the bridge road surface is covered with sound-insulating roll glue, and the bottom end of the side of the concrete guardrail is provided with installation grooves, the installation grooves A stainless steel fixing plate is connected inside, a steel beam is welded on the top of the stainless steel fixing plate, a shock-absorbing buffer plate is vertically fixed at one end of the steel beam, a fixing frame is installed on one side of the shock-absorbing buffer plate, and a sound insulation board is installed on the inside of the fixing frame. A bending section is distributed, and one end of the bending section is connected with a second sound insulation cotton, and a first noise dispersing cavity is arranged on one side of the second sound insulation cotton. In the present invention, through the provided bending section, when the noise touches the sound insulation board, it is first dispersed through the bending section, then weakened by the second sound insulation cotton, and finally the noise is further reduced by the first noise dispersion chamber and the second noise dispersion chamber. Scattered treatment, good use effect.

Description

technical field [0001] The invention relates to the technical field of municipal engineering equipment, in particular to a bridge sound insulation structure for municipal engineering. Background technique [0002] With the development of social economy, the scale of the city continues to expand, and the viaduct, which is the main line of urban road traffic, directly passes between the high-rise buildings in the city. For schools, office buildings and other places on the roadside, noise has become a new source of pollution. People will Being in the noise pollution of cars and trains for a long time will seriously affect people's school, work and rest. The current method is to install barrier panels on the roadside of viaducts and viaducts. Traditional barrier panels are generally made of metal plates and are heavy. , It is more laborious to install.

[0002] With the development of social economy, the scale of the city continues to expand, and the viaduct, which is the main line of urban road traffic, directly passes between the high-rise buildings in the city. For schools, office buildings and other places on the roadside, noise has become a new source of pollution. People will Long-term noise pollution from cars and trains will seriously affect people's school, work and rest. The current method is to set up barrier panels on the roadside of viaducts and viaducts. Traditional barrier panels are generally made of metal plates and are heavy. , It is laborious to install. The sound-absorbing panels currently used on the road are mainly insulated by sound-proof cotton, which cannot achieve real sound-absorbing effects, and the sound-insulating effect is not very ideal.

On the other hand, the existing sound insulation wall cannot be disassembled after installation, and at the same time, it does not have the anti-collision function. When an accident occurs, the sound insulation wall is easily damaged, it is not easy to maintain, and the structure is very unreasonable
