Embodiment Construction

[0019] The specific implementation is to divide the double-track track into first-line 1 and second-line 2, with first-line 1 being constructed first, and second-line 2 behind first-line 1; For the off-line detour 3, a level crossing where the off-line detour is connected to the line is set in the transition section, so that vehicles on and off the line can pass;

[0020] figure 1 , figure 2 As shown, the construction of the first-line bed slab uses the second-line foundation bed 4 with a width greater than 7.0m and has not yet constructed the second-line bed slab as the first-line on-line access road, and the offline engineering materials, turnover materials, machinery and equipment, and concrete of the first-line construction pass through the second-line foundation bed 4 transport with tire type concrete transport vehicle 5;

[0021] figure 2 As shown, during the construction of the second-lane bed slab, the concrete of the second-lane bed slab is transported to the lev...

Abstract

The invention discloses a double-line construction method for a double-block ballastless track bed board of a railway passenger special line, which is characterized in that: a double-line orbit is divided into a first line and a second line; the first line is constructed firstly, and the second line is constructed after the first line; an access road which is parallel to the line and constructed in civil engineering construction below the line is used as the access road below the line; a first line track bed board takes a second base bed of the second line track bed board without being constructed as the access road on the first line; the second line track takes the paved first line orbit as the access road on the second line; and the first line and the second line are two individual construction production lines. In the construction method, the construction progress can be reasonably arranged; corresponding sections which are constructed previously can be effectively utilized; the logistics problem of the ballastless track bed board is solved; and the construction efficiency and the construction quality are ensured, the construction cost is reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a double-line construction method for a double-block ballastless track bed slab on a railway passenger dedicated line. Background technique [0002] High-speed railway has become the development trend of my country's railways, but the relevant construction technology is still immature, and many aspects are in the exploration stage, especially the construction access road and logistics issues. Germany and France, where the wheel-rail high-speed railway is more developed, have relatively short high-speed railway lines, the longest of which is only a few hundred kilometers. Its terrain is relatively flat, and it is easy to build parallel construction access roads, and construction equipment, materials and concrete can be easily transported in place through the construction access roads. [0003] In my country, the territory is vast and the terrain is changeable. A high-speed railway often has to cross plains, mountains, rivers, h...
