[0002] Ballastless track, also known as ballastless track, refers to a track structure that uses a monolithic foundation of concrete or asphalt mixtures instead of a granular gravel roadbed. It is currently the world's most advanced track technology. Slab ballastless track is a new type of track structure consisting of a concrete base, a CA mortar layer or self-compacting concrete, track slabs, fasteners, and rails.

[0003] With the rapid development of the railway industry, CRTS III ballastless track slabs have also been widely used. During the laying process of the ballastless track slabs, the position of the ballastless track slabs needs to be precisely positioned and adjusted, so fine-adjustment claws connecting the ballastless track slabs and the foundation are required. However, the existing compensating fine-adjustment claws are manually adjusted and controlled by workers during use, so the adjustment height needs to be precisely controlled by workers, which will cause workers to repeatedly measure and adjust, which is work-intensive.
