Assembly type track and cushion structure thereof

Abstract

The embodiment of the invention provides an assembly type track. The assembly type track comprises a base, a prefabricated track bed module and flexible pads; the flexible pads are arranged between the base and the prefabricated track bed module to buffer the force between the base and the prefabricated track bed module; the flexible pads comprise N kinds of flexible pads, wherein n is an integergreater than 1; N kinds of flexible pads thickness value are different, and the flexible pads are used for assembling or selecting elastic elements according to the vibration reduction level of the track. Compared with the prior art which adopts the technical scheme of pouring self-compacting concrete or CA mortar and other filling materials between a suspended track plate and the base to form theadjustment layer, the assembly type track provided by the embodiment of the invention, adopts the flexible pads as the buffer and vibration reduction structure between the base and the prefabricatedtrack bed module to compensate the unevenness error of the assembly contact surface and avoid the rigid contact between the concrete member so that the vibration reduction can be ensured and at the same time, the production and assembly of the assembly type track can be adapted, and the subsequent maintenance is easy.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transit, and in particular to an assembled track and its bedding structure. Background technique [0002] Large-capacity, energy-saving, environmentally friendly, safe and fast rail transportation. The track is the foundation of the transportation equipment. The track directly bears the load of the train and guides the train to run. The track structure must have sufficient strength and stability. The domestic high-speed railway with the world's first operating mileage adopts different types of prefabricated track slabs and CA mortar or self-compacting concrete pouring positioning technology, and fills filling materials such as self-compacting concrete or CA mortar between the suspended track slab and the foundation to form adjustments Floor. If the application of green construction is promoted in urban rail transit, the underground railway is limited by the transportation c...

AI Technical Summary

Problems solved by technology

If the application of green construction is promoted in urban rail transit, the underground railway is limited by the transportation conditions of the tunnel space and the fluidity and rapid solidification requirements of the filling materials. Not only the construction process is complicated, but the filling materials are more wasted and the construction efficiency is low.

In addition, the adjustment layer is the weak link of the track structure in the daily track transportation process, and it is difficult to maintain
