Description
Technical Field
The utility model relates to the technical field of rail transit, in particular to a waterproof vibration reduction pad rail plate.
Background
With the vigorous development of urban rail transit industry in China, the influence of environmental vibration caused by train operation on daily life and work of people is more serious. In recent years, researchers at home and abroad have made a great deal of work on how to control the vibration and noise of the rail transit environment, and a great deal of effective measures are formed, namely a vibration reduction pad ballast bed. The damping pad is paved between the track bed and the foundation, and the damping is increased by reducing the supporting rigidity of the track structure, so that the damping purpose is achieved, the damping pad is firstly adopted in Berlin subways in 1975, is later applied to European national railways, and is applied on a large scale in 2009 in China.
The vibration damping pad has different types of technical branches in the development process, and can be mainly divided into polyurethane vibration damping pad and rubber vibration damping pad according to materials. Most of the microporous polyurethane vibration damping pads are of an open-pore plate type structure, elastic deformation is realized through volume compression, when the microporous polyurethane vibration damping pad is used in water environment, water can enter the vibration damping pad along the pores, so that the rigidity of the vibration damping pad is increased, and the vibration damping performance is reduced; in addition, microorganisms and mould in water can also infiltrate into the damping pad, and the internal structure of the damping pad can be destroyed along with the time, so that the application effect of the floating plate ballast bed of the damping pad is affected, and the application requirements of a rainy area and a region rich in underground water are difficult to fully meet. The rubber vibration-damping pad is generally made of compact materials, is incompressible in volume, realizes elastic deformation through compression deformation of a bulge or hole-type structure, and common shape structures include a substrate-conical bulge shape, a surface layer-prismatic table shape, a corrugated shape, a hollow hole shape and the like. Once wind or water flows transport sundries such as sand into the gaps or calcified substances in the water deposit and calcifie in the gaps, the gaps are gradually filled, the vibration damping performance of the vibration damping pad is drastically reduced, and the vibration damping effect of the ballast bed is correspondingly deteriorated. In addition, the existing vibration damping pad floating plate ballast bed has the defects of complicated construction process, low construction speed and the like because the vibration damping pad is cut on site, the splice joint is processed and the concrete ballast bed is paved.
