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 deterior

Embodiment Construction

[0053] see figure 1 , The present invention relates to a prefabricated damping track structure system, said prefabricated damping track structure system is multi-layer design, including filling layer 1, elastic cushion layer 4 and track plate 6 sequentially from bottom to top.

[0054] Wherein, the filling layer 1 is the bottom layer, and the elastic cushion layer 4 is laid on the filling layer 1. Preferably, the filling layer is made of self-compacting concrete, so as to provide good fluidity when pouring, and can provide a good support effect. The end of the elastic cushion layer 4 is a sealing material (such as polyurethane caulking glue) 15 to ensure that dust, sundries, water, etc. do not enter the space between the elastic cushion layer 4 and the track 6 or between the elastic cushion layer 4 and the filling layer 1. gap.

[0055] The elastic cushion layer 4 is arranged on the filling layer 1 to provide the elastic cushioning of the filling layer 1 and avoid its rapid ...

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.
