Assembled track structure with built-in limiting modules

Abstract

The invention discloses an assembled track structure with built-in limiting modules. The structure comprises a base plate, the top face of the base plate is in millimeter-level precision through cast-in-place, or the base plate is prefabricated and formed in a factory, and a leveling adjusting layer is formed on a supporting foundation through cast-in-place, or the base plate is replaced with asphalt or high-performance concrete or an exiting novel material, the base plate is pressed down and formed by the track plate during cast-in-place so as to form a top surface with millimeter-level precision, a middle layer is laid on the base plate, a track unit is laid on the middle layer and comprises track plate modules which are sequentially arranged, and the track plate modules are prefabricated and formed; and the track unit further comprises a limiting blocking table used for conducting elastic limiting on the connected track plate modules in the longitudinal direction and the transverse direction, and the lower end of the limiting blocking table is fixed to the base plate. In the structure, multiple modules are combined, the applicability is high, the prefabricated modules are miniaturized and light, production, transportation and installation are convenient, the structure is simple, the assembly method is simple and convenient, the assembly efficiency is high, and replacement is easy.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an assembled rail structure with built-in limit modules. Background technique [0002] my country's high-speed rail technology has developed from scratch, from weak to strong, and has gone through four stages. After more than 20 years of continuous efforts, China 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, there are more than 10 countries that are building high-speed rail, and more than 20 countries have implemented high-speed rail. Planning, the high-speed rail tr...
