Glass fiber reinforced polyurethane sleepers(synthetic sleepers/composite sleepers) takes into account all the advantages of concrete and wooden sleepers, and at the same time strengthens its own advantages: light weight, about 80% lighter than concrete sleepers; high strength, good track gauge maintenance; acid and alkali resistance, salt spray resistance, ultraviolet resistance, and damp heat resistance Good aging performance; insulation, flame retardant, insect-proof; low overall life cycle cost, etc.

Chamber filling elements are made of tyre granulate, polyurethane adhesive and water. They are composed of an external and internal element as well as an elastic rail foot boot.The rail dampers reduce noise and vibration by transforming the vibration energy into heat, through their large internal friction.

Tunnel Segment Bolts Application: subway shield, pipeline segment connection, shallow buried longitudinal segment bolt, building segment connection, subway segment connection.
