GZJ1500/2500 hydraulic drilling rigs are mainly used for WSS Grouting technology which is double tube grouting at the ends of hole. Grouting works drilling rig can grouting cement, sodium silicate double slurry, and worked in subway, tunnel construction and other projects for sealing the foundation pit gushing water, collapse, land subsidence, etc. which caused by underground water, quicksand, karst cave.
