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...
