AI Technical Summary

Technical Problem

The high-speed maglev track slab has insufficient structural rigidity and durability, making it prone to cracking and unable to effectively withstand the dynamic load of the train, thus affecting its service life.

Method used

A high-speed maglev prestressed track slab is designed, which adopts a rectangular structure with longitudinal and transverse prestressed steel bars. Prestress is applied by adjusting the mechanism, and it is connected with guide plates and sliding plates. The prestress is applied by post-tensioning.

Benefits of technology

Improve the structural strength and rigidity of the track slab, extend its service life, reduce structural cracks, enhance the connection stability between the track slab and the underlying concrete, and reduce the difficulty of maintenance.
