Along with the raising of people's living standard, also more and more higher to environment requirement.Railway traffic will be walked the road of sustainable development, when improving traffic, also will guarantee good living environment.This just requires to the more sensitive location of vibration and noise, should take the track vibration-reducing measure to satisfy requirement on environmental protection carrying out railway planning, design, when building, must taking into full account the influence to environment along the line according to the vibration and noise index.In existing non-fragment orbit, vibration and noise mainly is to control by the measures such as acoustic screen that are arranged on the circuit both sides.
Summary of the invention
Technical problem to be solved by this invention provides a kind of plate-type ballastless track vibration-reducing construction, can reduce vibration and noise effectively, and applying to responsive location can be controlled at the vibration and noise of track structure in the set quota.
The technical solution adopted for the present invention to solve the technical problems is: plate-type ballastless track vibration-reducing construction of the present invention, comprise the track plate that vertically lay on bearing bed and road along the line, and the adjustment layer between bearing bed, track plate, it is characterized in that: be provided with the elastic damping layer between the bottom surface of the end face of described bearing bed and adjustment layer, bearing bed has the position limiting structure that acts on the self-compacting concrete layer.
Described elastic damping layer is made of the two row rubber pads that are horizontally arranged at interval along bearing bed.
The invention has the beneficial effects as follows to have the favorable damping effect, can reduce vibration and noise effectively, applying to responsive location can be controlled at the vibration and noise of track structure in the set quota, guarantees good living environment.
