Novel prefabricated plate type damping track structure for rail traffic

Abstract

The invention relates to a novel prefabricated plate type damping track structure for rail traffic. The novel prefabricated plate type damping track structure consists of steel rails, fasteners, prefabricated plates, an elastic cushion, sealing sleeves, a vertical connecting device, a filling layer and the like, wherein the elastic cushion and the prefabricated plates can be integrally compounded in a plant; holes which penetrate through track plates in the thickness direction can be reserved in the track plates to fill the filling layer and observe the filling condition; pre-formed holes allowing supporting legs to be mounted and a hole allowing a measuring positioning sign to be mounted are formed in the track plates; a centering sign for paving positioning, an embedded component for the compound connection of the elastic cushion, hoisting nails for hoisting, an embedded component for longitudinal connection of the track plates, an embedded component for mounting contacting rails and the like can be reserved in the track plates. According to the novel prefabricated plate type damping track structure disclosed by the invention, the problems of quick and high-accuracy construction and subsequent replacement are solved, and the novel prefabricated plate type damping track structure has the characteristics of being simple in construction operation procedure, high in construction speed, high in accuracy, good in track ride smoothness, low in labor intensity and the like, and conforms to the current rail traffic requirements of being environmentally-friendly, high in efficiency and low in disease, so that the problems of vibration caused by the operation of city rail traffic vehicles and secondary structure noise can be effectively reduced.

Description

technical field [0001] The invention relates to the field of vibration reduction of rail traffic, in particular to a novel prefabricated slab type vibration-damping track structure for rail traffic. Background technique [0002] With the large-scale network development of urban rail transit, the construction period of urban rail transit is becoming increasingly tight. The construction process of the track structure is closer to the opening and operation time, and the pressure on the construction period is particularly prominent. Generally, the track laying period of about 9 months for a subway line is often compressed. It takes 6 months or even less. The traditional track structure determines the characteristics of many construction operations, manual work, difficult control of construction accuracy and slow construction progress. When the overall construction period and track-laying period are compressed, the construction accuracy and track-laying quality are seriously affe...

Problems solved by technology

[0002] With the large-scale network development of urban rail transit, the construction period of urban rail transit is becoming increasingly tight. The construction process of the track structure is closer to the opening and operation time, and the pressure on the construction period is particularly prominent. Generally, the track laying period of about 9 months for a subway line is often compressed. It takes 6 months or even less. The traditional track structure determines the characteristics of many construction operations, manual work, difficult control of construction accuracy and slow construction progress.

When the overall construction period and track-laying period are compressed, the construction accuracy and track-laying quality are seriously affected, resulting in the deterioration of the smoothness of the line put into operation and the comfort of running vehicles, and the frequent occurrence of track diseases, and the aggravation of environmental vibration and noise problems

[0003] The traditional vibration-absorbing track structure adopts the construction method of binding steel bars on site and pouring concrete. Generally, the daily construction speed is 25m to 50m, and the number of construction personnel is 80 to 100. Narrow and a large number of manual work links lead to low construction accuracy, low work efficiency, and high safety risks, and the cost of design, construction and maintenance also increases

In addition, line diseases in the cast-in-place vibration-damping track section occur from time to time, such as the track bed is easy to crack, etc.
