Data processing method for integrated slab layout and construction of CRTSIII type ballastless track

Abstract

The invention relates to a data processing method for integrated slab layout and construction of a CRTSIII type ballastless track. CRTSIII type ballastless track slabs lack an appropriate data processing method for data calculation and organization in the processes of slab layout designing, installation, positioning and maintenance. The data processing method for integrated slab layout and construction of the CRTSIII type ballastless track comprises the steps of establishing a route foundation database and carrying out unified management on data with a route mileage as the index; determining slab layout design data and determining the number and the type of the track slabs along the route in a fixed section; adjusting the size of a mould for prefabricated rack slabs of a factory; taking deformation caused by a design load into account and working out installation and positioning coordinate data and three-dimensional coordinates of track benchmark lattice points laid along the middle line of a route. By means of the data processing method for integrated slab layout and construction of the CRTSIII type ballastless track, a structural design is carried out on track slab layout, mould adjustment for fabricated slabs and construction installation data, combination of spatial coordinate data and the route mileage is achieved, the route essential data adopted by a design stage can be directly shifted into a track slab prefabrication and construction installation stage for use, and integration of the design and construction data is achieved.

Description

technical field [0001] The invention belongs to the technical field of rail transit construction, and in particular relates to a data processing method integrating slab layout and construction of a CRTS III ballastless track. Background technique [0002] CRTSIII slab ballastless track is a new type of ballastless track structure. It is based on the mature experience of the design, construction and maintenance technology system of CRTSI and CRTSII slab ballastless track, combined with the unique technical route of passenger dedicated lines in my country, and continuously improves awareness , After repeated revisions and improvements, the new high-speed rail ballastless track technology system with China's independent intellectual property rights has been researched and developed. In the CRTSIII type slab ballastless track system, the layout of the track slab is combined with the line design, the track slab is prefabricated in the factory, and the advanced numerical control a...

Problems solved by technology

[0003] Since CRTSIII ballastless track slab is a newly emerging ballastless track technology, there is no suitable data processing method for data calculation and organization in the process of ballastless track layout design, installation positioning, and maintenance. In the track layout design and positioning measurement, the design and slab construction data are organized and managed by different units, and there is no method to realize the integration of design and construction data organization, management, and calculation
