Floating slab and floating track bed thereof

Abstract

The invention belongs to the field of the rail transport, and in particular to track bed slabs and a floating track bed formed by track bed slabs. The floating slab and floating track bed thereof comprise a floating slab body, an installing reserved space or a jointing sleeve matched with an elastic isolation mounting is arranged on the floating slab body, the connecting end of the floating slab body is provided with a first assembly hole and a second assembly hole, and the first assembly hole and the second assembly hole are arranged in the vertical plane of the floating slab body; the first assembly hole is inclined and penetrates through the floating slab body, an opening in the upper portion is arranged on the top face of the floating slab body, and an opening of the lower portion is arranged in the connecting coordinated face of the floating slab body; the second assembly hole is inclined and penetrates through the floating slab body, an opening of the upper portion is arranged in the connecting coordinated face of the floating slab body, the lower portion of the second assembly hole is provided with an assembly connector, and the assembly connector is located on the bottom of the floating slab body. The floating slab has the advantages that the structure is simple, the manufacture is easy, and the use is convenient. By means of the floating track bed formed by connecting the floating slabs, the efficiency of construction is high, the post-maintenance is convenient, the vibration performance is more excellent, the stress is more reasonable, and the service life is longer.

Description

technical field

[0001] The invention belongs to the field of rail transportation, and in particular relates to a ballast bed slab and a floating ballast bed formed therefrom. 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 floating ballast bed technology is recognized as one of the technologies with the best v...
