Double-block type ballastless track retesting method and system

Abstract

The embodiment of the invention provides a double-block type ballastless track retesting method and a system. The method comprises the following steps: adjusting a retesting frame in a to-be-retestedarea of a ballastless track; setting parameters such as curve elements, a roadbed slab and a sleeper number of a data acquisition terminal, measuring a prism center of a retesting frame by using a total station so as to acquire the actual three-dimensional coordinates of any sleeper to be measured and the deviation value of the sleeper, sending deviation data and alarm information to an information management platform. The retesting system is composed of a total station, a retesting frame, a data acquisition terminal and an information management platform, sleeper deviation data can be analyzed, and construction quality problems can be found. The method and system can reflect the construction precision of the double-block ballastless track, can complete the full coverage of the construction precision inspection of the ballastless track, are high in operability and efficiency, can solve a problem of the great quality of ballast bed construction after the long track is laid, and improvethe digitalization, informatization and lean management level of track construction.

Description

technical field [0001] The invention relates to the technical field of track engineering, in particular to a double-block ballastless track retesting method and system. Background technique [0002] The double-block ballastless track has been widely used in the construction of high-speed railways in my country, and has experienced the practice of the track arrangement method and the artificial track arrangement method. At present, the construction mode of the track geometric state measuring instrument plus the tool rail row support method has been gradually matured and applied. Generally, a portable computer, a Leica total station, a track fine adjustment system and a track inspection trolley are used for rough and fine adjustment of the ballastless track. work, but this mode has disadvantages such as easy distortion of retest results and low efficiency of rail frame turnover. Contents of the invention [0003] In view of the above problems, the embodiment of the present ...
