Shock absorption and noise reduction device for highway bridge

Abstract

The invention relates to a shock absorption and noise reduction device for a highway bridge. The shock absorption and noise reduction device comprises a pier, a placing platform, pavements and a shockabsorption device, wherein the upper end of the pier is provided with the placing platform, the pavements are bilaterally symmetrically placed at the left side and right side of the upper end face ofthe placing platform, the left and right end faces of the pavements are inclined slope surfaces, a groove is formed between the two pavements at the left end and right end of the placing platform, the groove is internally provided with the shock absorption device, the shock absorption device comprises a shock absorption surface, the upper end of the groove is provided with the shock absorption surface, the shock absorption surface is of a cambered surface structure, the shock absorption surface is made from a rubber material, the lower end of the inner portion of the shock absorption surfaceis provided with a steel plate, the upper end face of the shock absorption surface is provided with a circular groove, and the circular groove is internally provided with sound-absorbing sponge. The shock absorption and noise reduction device for the highway bridge has the advantages that the problems of vehicle jolting, noise increase and even traffic accidents which are caused by the fact that the steel plate pavement has no shock absorption and noise reduction effect when the bridge pavement is spliced are solved, the functions of shock absorption and noise reduction of the highway bridge can be achieved, the shock absorption effect is good, and the generated noise is small.

Description

technical field [0001] The invention relates to the field of highway bridges, in particular to a vibration and noise reduction device for highway bridges. Background technique [0002] With the continuous improvement of the level of economic development, in recent years, my country's investment in national road construction projects has also increased, and the length of my country's annual road construction has also continued to increase. The construction of road networks has provided convenience for economic development. At the same time, my country's technology in the field of road and bridge construction is becoming more and more mature. [0003] When the car is driving on a road section with a bridge, the road surface will be uneven, resulting in bumps, and the noise will also increase. This is because the road on the bridge section uses road splicing. At the same time, a steel plate pavement will be added to the upper end of the joint to reduce the damage to the joint b...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a vibration damping and noise reduction device for highway bridges, which can solve the problem of vehicle bumps, increased noise and even traffic accidents caused by the lack of shock absorption and noise reduction effects on the steel plate road surface when the bridge road surface is spliced. It can realize the functions of shock absorption and noise reduction of highway bridges, and has the advantages of good shock absorption effect and low noise generation
