Ballastless track with continuous wide sleepers with floating anti-vibration pads
The invention relates to a continuous wide sleeper type ballastless track with a floating anti-vibration pad. A cast-in-place anti-vibration pad floating slab track has the problems of high construction difficulty, poor smoothness, difficulty in maintenance in an operation period and the like, and a prefabricated floating slab track has the problems of large size and weight, difficulty in track slab reshipment, difficulty in track fine adjustment and the like. The rail comprises a wide sleeper, an anti-vibration pad and a base. The anti-vibration pad is arranged on the top face of the base, the wide sleepers are transversely arranged on the anti-vibration pad in a floating mode, and the wide sleepers are longitudinally and continuously arranged on the anti-vibration pad. The novel vibration reduction track structure is provided for the situation that vibration generated in track traffic operation exceeds 10 dB or below, the wide sleepers are continuously arranged in the line direction, arranged on the vibration reduction pad in a floating mode and directly arranged on the top face of the base, a cast-in-place or prefabricated roadbed slab structure or track slab structure in the prior art is omitted, and the vibration reduction effect is good. And the vibration reduction effect of the continuous supporting type floating slab is achieved.
本发明涉及一种减振垫浮置连续宽轨枕式无砟轨道。现浇减振垫浮置板轨道存在施工难度大、平顺性差、运营期维修困难等问题，预制浮置板轨道存在体积和重量均较大、轨道板倒运和轨道精调困难等问题。本发明的轨道包括宽轨枕、减振垫和底座；所述减振垫设置于所述底座的顶面，所述宽轨枕横向浮置于所述减振垫之上，所述宽轨枕在所述减振垫上纵向连续布置。本发明为轨道交通运营产生振动超标10dB以下的情况提供了一种新的减振轨道结构，采用浮置预制宽轨枕，将宽轨枕沿线路方向连续排布，浮置于减振垫上并直接设置在底座顶面，取消了以往现浇或预制的道床板结构或轨道板结构，达到连续支承式浮置板减振效果。
