Embodiment Construction

[0034] see figure 1 , figure 2 Shown, damping track pad of the present invention is formed by the conical protrusion on the base and the base, by being installed under the rail (see image 3 ), the pad can effectively reduce vibration and noise, with Figure 4 Shows the specific composition of the substrate, which consists of a damping layer 10, a rubber coating 9, a woven fabric layer 8, a rubber coating 7, an interlayer 6, a rubber coating 5, a woven fabric layer 4, a rubber coating 3 and a cover layer in sequence 2. There is an overlapping strip 1 in the covering layer, which can be used to connect and manufacture longer width and length damping track pads, for example, through two vibration damping track pads with a width of 1 meter. lap strips, so that a 2-meter-wide damping track pad can be formed; at the same time, multiple conical protrusions are formed on the damping layer 10 of the base, and the effect of bearing pressure is better by using the special-shaped sect...

Abstract

The invention relates to a vibration-reducing road pad and a method for paving a monolithic roadbed track by adopting the vibration-reducing road pad. The road pad comprises a substrate and conic protrusions; the substrate consists of a damping layer, a rubber coating layer, a woven fabric layer, a rubber coating layer, an interlayer, a rubber coating layer, a woven fabric layer, a rubber coating layer and a covering layer in sequence; the conic protrusions are formed on the damping layer, wherein the conic protrusions are arrayed on the substrate in an array shape; the vibration-reducing road pad can efficiently isolate structural vibration with noise of a high-speed railroad and similar objects, thereby reducing resistance and abrasion; and through tests, after the vibration-reducing road pad is arranged on the high-speed railroad by a packing method, the heavy axle load reaches 25 t, and the speed can reach 396 km / h.

Description

technical field [0001] The invention relates to a damping track mat and a railway laying method using the damping track mat, in particular to a damping track mat applied to high-speed railways and a high-speed railway laying method using the damping track mat. Background technique [0002] In my country's railway construction, the importance of high-speed railways is increasing. In the construction of high-speed railways, it is necessary to solve the impact of vibration and noise generated by vehicles running quickly on the operation and track bed, otherwise its service life will be greatly shortened. , the probability of failure is also greatly increased. In order to overcome the interference and damage of vibration and noise to the stability of the ballast bed and the operation of the vehicle, it is necessary to have technologies and products that can effectively reduce vibration and noise to ensure the safety of the line operation and achieve the desired speed. . [0003] ...
