Abstract

The invention relates to an easy-to-assemble floating track bed precast slab and an application thereof, which belong to the field of rail transit. According to the invention, the easy-to-assemble floating track bed precast slab can conveniently establish reliable connection with an adjacent floating slab and can smoothly transmit a shear force and improve the force born on the floating slab; and meanwhile, the integrality of a floating track bed structure can be also effectively enhanced, the adaptability of the easy-to-assemble floating track bed precast slab is enhanced and the service life of the easy-to-assemble floating track bed precast slab is prolonged. According to the invention, the easy-to-assemble floating track bed precast slab comprises a precast slab body, wherein the middle part of a connecting end of one side of the precast slab body is fixedly provided with locating guide sleeves; the middle part of a connecting end of the other side of the precast slab body is correspondingly provided with join-assembling holes; the locating guide sleeves and the join-assembling holes are respectively arranged in a longitudinal direction of a track; at least two locating guide sleeves are arranged; the number of the join-assembling holes is as same as that of the locating guide sleeves; a grouting passage is formed in the precast slab body; one end of the grouting passage is communicated with the bottoms of the join-assembling holes; and the other end of the grouting passage is open in the upper surface of the precast slab body. The easy-to-assemble floating track bed precast slab, provided by the invention, is mainly used for the construction of rail transit.

Description

technical field

[0001] The invention belongs to the field of rail transportation, and in particular relates to a prefabricated ballast bed slab, a floating ballast bed formed by the prefabricated ballast bed, and a method for forming the floating ballast bed. Background technique

[0002] With the development of society and the progress of science and technology, the importance of rail transit has become increasingly prominent. In the construction of rail transit, the vibration and noise problems generated during vehicle operation must be solved, otherwise it will seriously affect the quality of life of surrounding residents and endanger the safety of surrounding buildings. At the same time, the stability, safety and service life of rail transit itself will also be affected. affected. In order to control the vibration and noise generated in the operation of rail transit, researchers have developed many vibration and noise reduction products, among which the steel spring flo...
