External limiting module split mounting type track structure

Abstract

The invention discloses an external limiting module split mounting type track structure which comprises a base plate, the base plate forms top face millimeter-level precision through cast-in-place or is prefabricated and formed in a factory, an adjusting layer is cast in place on a foundation or is replaced by novel materials such as asphalt, and the base plate is pressed downwards by a track plate during cast-in-place so as to form the top face millimeter-level precision; a middle layer is laid on the base plate, track units are sequentially laid on the middle layer, and each track unit comprises a prefabricated track plate module; a concave-convex embedded structure is further arranged between every two adjacent sets of track plate modules. The further comprises two sets of limiting strips, the two sets of limiting strips are arranged on the two sides of the track plate module respectively, and the limiting strips are connected to the supporting foundation and abut against the track plate module for limiting. 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 transit, in particular to an assembled track structure of an external limit module. 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. [0003] Ballastless track structure has become the main track structure type of high-speed railway due to its advantages of high smoothness, high stability, and less maintenance. The commonly used structure consists of track slab, filling layer, concrete base or support layer. At present, the main components of the high-speed railway slab ballastless track structure are prefabricated in ...
