Abstract

The invention relates to the field of track detection, and discloses a ballastless track measuring method and device. The method comprises the following steps: mounting a rail inspection trolley on ato-be-measured steel rail after lofting construction of a ballastless slab track, and mounting a total station at a position away from the central axis of the steel rail behind the rail inspection trolley; setting parameters of the total station according to the parameter setting manual of the total station and the currently measured environment; controlling the track inspection trolley to sequentially move to the positions of the CPIII control point pairs marked on the ballastless track, and collecting track gauge data; controlling the total station to acquire prism coordinate data when the rail inspection trolley moves to the CPIII control point pair position; inputting the track gauge data and the prism coordinate data into preset processing software to obtain a track error; judging whether the track error exceeds a preset error threshold value or not; and if so, adjusting the screw rod to correct the rail error of the steel rail until the error reaches the standard. Measurement ofthe ballastless track is more complete, and ballastless track measurement accidents are efficiently reduced.

Description

technical field [0001] The invention relates to the field of track detection, in particular to a ballastless track measurement method and a device thereof. Background technique [0002] In recent years, with the continuous increase in the mileage of high-speed rail construction, the construction technology of high-speed rail has also been continuously improved. In the ever-upgrading track construction technology, ballastless track, as a new track technology, has very high requirements for stability, continuity and smoothness, and the track measurement accuracy reaches millimeter level. [0003] In the existing technology, there must be a complete, efficient and very accurate measurement system, otherwise the construction of the ballastless track will cause measurement accidents due to huge deviations. Therefore, it is necessary to establish a complete and efficient measurement system to improve the accuracy of ballastless track measurement. Contents of the invention [0...
