Embodiment Construction
[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0054] A specific construction process of a long sleeper buried type large ballastless turnout method for passenger dedicated lines per hour, as shown in Figure 1, including the following steps:
[0055] (1) Concrete construction of the base of the turnout area
[0056] The base of the turnout area is a C30 reinforced concrete structure, which is arranged in a trapezoidal shape according to the line shape of the turnout. The concrete is constructed by factory-mixed concrete and continuous pouring. Rough base concrete surface.
[0057] (2), construction measurement and stakeout
[0058] Use high-precision total station and electronic level to re-measure the CPIII reference network in the range of 300m before and after the turnout, stake out the turnout foundation piles at the turnout center, fork tail, fork head, starting and ending points of the curve...
