[0002] The traditional track laying method in various countries is to assume that the track has reached the design position first, and all fasteners are standard fasteners to be ordered and purchased, and then calculate the real offset according to the data collected by the track measuring instrument, and then provide a real fastener model. To replace the standard fasteners during track laying, in the existing construction process, the "fine measurement and fine adjustment in absolute mode" process is to detect the real position of the track through the track geometric state detector, and calculate the real position and design position of the track through software If there is any deviation, then use the adjustment parts to replace the original standard parts, and the replaced standard parts will be treated as waste. The replacement rate is over 80%, resulting in great waste

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] Such as figure 1 Shown, this embodiment adopts following technical scheme: its construction steps are as follows:
[0024] 1. Carry out rough paving of the track slabs. After rough paving, fine-tune the track slabs. After fine-tuning the track slabs (including double-block type), ensure the necessary pouring and curing time;
[0025] 2. The staff gather at the designated upper crossing, and arrange all the tools and materials neatly in a suitable posit...

The invention discloses a novel rail laying method for a ballastless rail of a newly-built high-speed railway, and relates to the technical field of rail construction. The method comprises the steps:carrying out rough laying of a rail plate, after rough paving, carrying out fine tuning of the rail plate; Re-testing each rail bearing platform of the rail plate; enabling professionals to calculatea real model of each rail bearing platform and export a material schedule; requesting a material department to purchase adjusting stop blocks and gaskets according to the specific model and quantity of the adjusting stop blocks and the gaskets which are actually used; laying the adjusting stop blocks and the gaskets on all the rail bearing platforms in advance according to the scheme; performing rechecking and error correction according to the material detail table; laying long rail bars by using a rail layer, welding, diffusing prestress, and locking rails; and carrying out small-range fine adjustment and defect elimination on the local deviation rail bearing platform, so as to enable the local deviation rail bearing platform to meet the high-speed rail technical standard. The rail platelaying quality can be truly reflected, data are provided for the next procedure, the work efficiency and accuracy of placing the adjusting piece are improved, resource waste is reduced, and practicability is higher.
