Embodiment

[0047] see Figure 1~6 , the longitudinally assembled prefabricated slab track in the preferred embodiment of the present invention includes a rail structure 1, which is arranged side by side, and is mainly used for guiding the vehicle forward; an assembly structure 2, which is arranged below the rail structure 1, mainly It is used for the stable placement of the rail structure 1; the lower foundation 3 is used for leveling the ground to facilitate the setting of the assembly structure 2 and the installation of the rail structure 1. It is set under the assembly structure 2 and used for the upper rail structure 1 and the assembly structure 2 bearing force and distribute the force to the ground. Wherein, the assembly structure 2 includes an assembly assembly 201, a tension assembly 202 and a limit assembly 203. There are a plurality of assembly assemblies 201, and a plurality of assembly assemblies 201 are arranged side by side in sequence along the longitudinal direction. Betwe...

Abstract

The invention discloses a longitudinally assembled prefabricated plate type rail, which belongs to the technical field of urban rail transit structures and comprises steel rail structures which are arranged side by side and mainly used for guiding vehicles to advance; an assembling structure which is arranged below the steel rail structure and is mainly used for stably placing the steel rail structure; and a lower foundation which is used for leveling the ground, facilitating the arrangement of the assembly structure and the installation of the steel rail structure, is arranged below the assembly structure, and is used for bearing force on the upper steel rail structure and the assembly structure and dispersing the stress to the ground. According to the longitudinally assembled prefabricated plate type track, the assembly structure forms a unit modular structure, the limiting assemblies are used for limiting, supporting and leveling the assembly assemblies, and the size and the structure type of the limiting assemblies are adjusted, so that the line type of the whole track is adjusted, and integrated construction of the adjusting layer and the limiting structure is achieved; the construction process is simplified, and the construction efficiency of the track structure is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to a longitudinally assembled prefabricated slab track. Background technique [0002] With the continuous advancement of urbanization in China, more and more people are concentrated in big cities for work and life. The large concentration of population has caused inconvenience to traditional public transportation and driving, which is likely to cause congestion problems. More and more people choose Travel by subway and light rail, and this also requires the efficient and rapid construction of urban rail transit such as subway and light rail. [0003] The current urban rail transit mainly adopts the cast-in-place track structure, which mainly has two forms: short-pillar integral track bed and long-pillow integral track bed structure. Among them, the short-sleeper monolithic ballast bed has a poor geometric position retention ability, and the rail bottom slope ...
