Problems solved by technology

The existing technology can no longer completely solve the problem. The floating slab technology can meet the requirements of vibration reduction and noise reduction. However, the traditional "scattered paving method" and "reinforcement cage method" need to bind the reinforcement mesh of the road bed slab and pour a large amount of concrete on site. The speed is slow, and it is not easy to control the quality on site
However, once a problem occurs with the floating plate in use, it will be difficult to repair and the cost will be high, which will affect the normal operation of the train.

Embodiment

[0022] Such as figure 1 The repairable prefabricated steel spring floating slab damping track system shown in the figure has a floating slab length of 3730mm, a slab width of 2700mm, and a gutter width of 400mm.

[0023] There are 3 vibration isolators under one prefabricated slab and one rail, and a prefabricated slab with a vibration isolator arranged every 2 fasteners (referred to as 22 layout), that is, 3 vibration isolators on the left and right sides of a prefabricated slab, a total of 6 isolators vibrator. The ends of the adjacent floating slabs are connected with the vertical and vertical two-way fixed connectors of the foundation under the railway track and the vertical and horizontal two-way fixed connectors of the foundation under the railway track. The observation tube is arranged at the horizontal and vertical two-way fixed connectors of the railway under the rails of the two floating slabs. There is a gap of 20mm between the two plates, and lifting sleeves ...

Abstract

The invention relates to a repairable vibration-reducing track system of prefabricated steel spring floating plates. A main body of the repairable vibration-reducing track system is steel spring floating plates, and two types of steel spring floating plates are included; for one type, two vibration isolators are arranged under one steel rail of one prefabricated plate, and are carried out according to a mode that one vibration isolator is arranged at an interval of 2-3 fasteners (short for 2-3 arrangement); for the other type, three vibration isolators are arranged under one steel rail of one prefabricated plate, and are carried out according to a mode that one vibration isolator is arranged at an interval of 2 fasteners (short for 2-2 arrangement); the plate ends of the adjacent floating plates are connected by using a foundation longitudinal-vertical two-way fixed connector under a railway and a foundation longitudinal-horizontal two-way fixed connector under the railway. The repairable vibration-reducing track system has the advantages of fast construction speed, low construction difficulty, easiness of repairing and the like.

Description

technical field [0001] The invention relates to the field of railway and urban rail transit, in particular to a floating plate damping track system. technical background [0002] Vibration and noise are serious public nuisance pollution in today's society, and it is also an urgent problem that affects the development of rail transit in recent years. The existing technology can no longer completely solve the problem. The floating slab technology can meet the requirements of vibration and noise reduction. However, the traditional "spreading method" and "reinforcement cage method" need to bind the reinforcement mesh of the road bed slab and pour a large amount of concrete on site. The speed is slow, and it is not easy to control the quality on site. And once the floating plate put into use goes wrong, it is difficult to maintain and the cost is high, which will affect the normal operation of the train. Prefabricated slabs are the current development trend to increase the cons...
