Introduction about ZZHZ Concrete Spraying System
Introduction about ZZHZ Concrete Spraying System
1. Concrete spraying system developed by ZZHZ is suitable for concrete spraying jobs for full-face tunnel and step construction method, road slope supporting concrete jet operations, large underground cavern concrete jet operations, excavation concrete jet operations. Our concrete spraying system can quickly finish spray operations. Its maximum injection capacity is 30m3 / h and full section spray area in the tunnel is 600m2.
2. Work Environment:
Ambient temperature: -10 ℃ ~ + 40 ℃
Field Altitude: not less than 3000 m
It is widely used in dusty and humid tunnel.
