Railway vibration isolation structure for railway construction

Abstract

The invention relates to the technical field of railway vibration isolation, and discloses a railway vibration isolation structure for railway construction. In order to improve the vibration isolationcapability of a railway vibration isolation mechanism, anti-seismic bases are fixed to the positions, located at the four corners, of the lower portion of a supporting bottom plate, the supporting bottom plate is connected with a supporting top plate through a vibration isolation rubber base, a buffer mechanism is fixed to the position, located on the outer side of the vibration isolation rubberbase, of the upper portion of the supporting bottom plate, and anti-seismic top bases are fixed to the positions, located at the four corners, of the upper portion of the supporting top plate. According to the railway vibration isolation structure, through the combination of the buffer mechanism and the vibration isolation rubber base, the single vibration isolation mode of a traditional vibrationisolation mechanism is replaced, the vibration isolation effect of a railway track is improved, and the situation that a railway section structure is cracked due to resonance can be avoided; and through supporting and fixing of the anti-seismic bases and the anti-seismic top bases, the vibration problem generated when a train passes can be solved, and then the vibration isolation efficiency of the railway vibration isolation mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of railway vibration isolation, in particular to a railway vibration isolation structure for railway construction. Background technique [0002] With the development of science and technology, the speed of railway trains can be roughly divided into three categories: high-speed railway, quasi-high-speed railway, and ordinary railway. As the main mode of transportation for current traffic, railways are distributed in various regions. In the process, it is often necessary to cross rivers, viaducts and other road sections. In order to improve the stability of railway train operation, a vibration isolation mechanism is usually added under the railway track to increase the stability of the railway track. [0003] However, there are some shortcomings in the railway vibration isolation mechanism currently on the market. The vibration isolation efficiency is insufficient, and the vibration problem generated when the ...

Problems solved by technology

[0003] However, there are some shortcomings in the railway vibration isolation mechanism currently on the market. Its vibration isolation efficiency is not enough, and it cannot reduce the vibration problem when the train passes by well. Moreover, the structure of the traditional railway vibration isolation mechanism is relatively simple, and the vibration isolation effect is relatively simple.
