A tunnel grout station is a complete set of equipment for grout preparation, storage, and high-pressure grouting in tunnel construction. It is mainly used for: grouting of pre-support (pre-support small guide pipes, pipe roof); grouting of backfill behind initial support; grouting of surrounding rock consolidation (water plugging + reinforcement); grouting of backfill behind secondary lining; and water plugging grouting in karst, water-rich faults, and fractured zones.
