Problems solved by technology
[0003] At present, the existing precise adjustment devices have the following characteristics: most of them are manually operated, require more manpower, have low efficiency, and are difficult to control the positioning accuracy; usually, the equipment needs to wait until the cement grouting is poured and solidified before it can be evacuated, which requires many sets of equipment work at the same time, thus greatly increasing the cost of each adjustment

Description
(1) Technical field [0001] The invention relates to railway tracks, in particular to a track slab adjustment device in the construction of ballastless tracks for high-speed railways. (2) Background technology [0002] Due to the needs of high-speed trains, high-speed railways mainly use slab-type ballastless tracks. The rails are not laid on ordinary sleepers, but on track slabs that have been precisely polished by machine tools to ensure line stability, safety, and low noise. . High-speed railways require the track to have strict smoothness in height and horizontal direction, in order to meet this requirement. After fine grinding and pre-laying (after rough paving), the track slab must be precisely adjusted and positioned, usually by using a precision measurement control network and advanced fine-tuning measuring instruments to continuously measure the spatial coordinates of each track slab in real time, and through The computer system performs real-time comparison with t...
