Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a track lateral distance detection device. Background Art

[0002] Track fine-tuning is mainly controlled by reference piles with a spacing of 60 meters next to the main track. All reference piles are designed to be on the same straight line. The design offset between the reference piles and the center line of the track is 1.4 meters, and the difference in elevation with the rail is 0.262 meters. Since the measured data of the reference piles is provided by the Chinese Academy of Sciences, the accuracy is very high.

[0003] The initial rough adjustment of the track mainly relies on the setting of the total station, and the measurement is performed by the surveyor holding a small prism by hand. However, manual operation is prone to errors. At the same time, the total station itself also has measurement errors. There are no special tools to verify the measurement data, resulting in inaccurate measurement data, which increases the difficulty of subsequent track fine-tuning operations.
