Built-in limit module assembled track structure

Abstract

The invention discloses an assembled track structure with a built-in limit module, comprising: a base plate, the base plate is poured on-site to form a top surface with millimeter-level accuracy, or the base plate is prefabricated in a factory, and a leveling adjustment layer is formed by on-site pouring on a support base , or the base plate is replaced by asphalt, high-performance concrete, or existing new materials, and the track plate is pressed down during on-site pouring to form the top surface with millimeter-level precision. The middle layer is laid on the base plate, and the track is laid on the middle layer unit, the track unit includes track slab modules arranged in sequence, and the track slab modules are prefabricated; the track unit also includes a limit stop for elastically limiting the connected track slab modules in the longitudinal and transverse directions, and the lower end of the limit stop Fastened to the base plate. In the structure of the present invention, the multi-module combination has strong applicability, and the prefabricated modules are miniaturized and lightweight, convenient for production, transportation and installation, simple in structure, convenient in assembly method, high in assembly efficiency, and easy to replace.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular, to a rail structure assembled with built-in limit modules. Background technique [0002] The development of my country's high-speed rail technology has grown from nothing, from weak to strong, and has gone through four stages. After more than 20 years of continuous efforts, my country has become the world's high-speed rail system with the most complete technology, the strongest innovation ability, the longest operating mileage, and the fastest operating speed. The fastest and largest country under construction. High-speed rail has also achieved unprecedented development in other countries around the world. At present, in addition to Japan, France, Germany, Italy, Spain, Belgium and other countries that have opened high-speed rail, more than 10 countries are building high-speed rail, and more than 20 countries have carried out high-speed rail. Planning, high-speed rail transit ...
