Tunnel Horizontal Jet Grouting Drilling Rig XPS-15

The XPS-15 tunnel horizontal jet grouting drilling rig is specialized equipment for advance pre-support in tunnel construction where weak strata such as aeolian sand are encountered. Using the jet grouting construction method, it forms a closed jet grouting pile curtain before tunnel excavation to seal against water and consolidate sand. The rig can also be equipped with different drilling tools for slope hazard mitigation, rock bolt installation, and other operations.
