Abstract

A floating vibration isolation structure of a track system is formed by a floating vibration isolation system on the bottom layer, a steel spring floating slab track vibration isolation system on the upper layer and a damped limiter. The floating vibration isolation system on the bottom layer is formed by a foundation rigid mass block and a floating rubber vibration isolation gasket which is arranged between a tunnel shield duct piece inner wall and the foundation rigid mass block. The steel spring floating slab track vibration isolation system on the upper layer is formed by rigid slab tracks and damped steel spring vibration isolators, wherein the damped steel spring vibration isolators are arranged on the foundation rigid mass block, tracks are arranged on the rigid slab tracks, and the damped steel spring vibration isolators have functions of adjusting preload. By arranging the secondary floating vibration isolation structure of the track system, the vibration caused by metros is controlled while provisions on dynamic subsidence of metro lines when the metros are in full-load operation can be met, and vibration isolation requirements can be effectively met especially at special sections sensitive to vibration.

Description

technical field [0001] The invention relates to a vibration isolation device, in particular to a floating vibration isolation structure for a track system. Background technique [0002] Because urban rail transit has the advantages of high speed, large passenger capacity, high safety and reliability, and no smoke emission pollution, it has been adopted as the main traffic line by many large and medium-sized cities at home and abroad in recent years to alleviate the traffic pressure brought about by urbanization. However, with the increase of train speed in our country, the vibration and noise problems of railways have become more and more prominent. If no effective measures are taken, it will not only reduce the comfort of passengers, but also reduce the service life of various parts of the vehicle, and also affect the The quality of work and life of residents along the railway and the life span of various equipment and buildings. Therefore, the vibration and noise caused b...
