Abstract

The invention relates to a precast rubber concrete vibration-absorbing track plate. The track plate comprises a rail plate main body and a rail bearing platform, a lifting hole is arranged on the sideof the rail plate main body, and an insulating sleeve is arranged on the rail bearing platform. The main body of the track plate is precast with rubber concrete of a specific proportion. The track plate is longitudinally arranged with self-compacting concrete penetrating grouting holes, and the end of the track plate is provided with limit holes to form a common vibration-absorbing track. Combined with rubber or polyurethane support blocks, support strips or plates, a composite damping rail is formed. The invention forms a new rail plate with certain elasticity by using rubber particles madeof waste rubber tyre, and has excellent vibration damping performance. The precast rubber concrete damping track plate has the advantages of vibration damping, easy fabrication, simple structure, easypopularization, and realizes the recycling of waste rubber.

Description

technical field [0001] The invention relates to the field of track slabs, in particular to a prefabricated rubber concrete damping track slab. Background technique [0002] With the massive construction of urban rail transit, more and more rail transit lines are close to or even pass through buildings that require vibration control, such as hospitals and scientific research institutions with high-precision instruments and ancient buildings that need special protection. In response to this, the industry mainly conducts vibration control through three methods: vibration reduction at the vibration source, vibration isolation through the transmission path, and vibration isolation at the vibration receiver. Among them, the vibration reduction measures at the vibration source mainly include vibration reduction fasteners, integral vibration reduction tracks, etc. At present, all integral damping tracks only achieve the purpose of track vibration reduction through different support...
