High pressure Jet Grouting Drilling Rig (high-pressure rotary jet drilling rig) is an innovative equipment in the field of foundation treatment. It forms a reinforced pile with a diameter of 0.6-2.5 meters by mixing cement slurry with soil through high-pressure jetting. The equipment is suitable for soft soil, gravel, rock, and other types of strata and is widely used in engineering fields such as construction, transportation, and mining.

Jet drilling rigapplication scenarios
- Deep foundation pit reinforcement of buildings. In the construction of high-rise buildings, the equipment can penetrate 30 meters underground to form a continuous wall, effectively improving the stability of the foundation pit. After using the YG drilling rig in a super high-rise project in Shanghai, the displacement of the support structure was reduced by 70%.
- Highway roadbed treatment. For the settlement problem of soft soil roadbed, high-pressure jet grouting technology can form a composite foundation, and the bearing capacity is increased by more than 40%.
- Mine tailings dam reinforcement. In the treatment of tailings ponds, the equipment can penetrate the loose tailings layer to form an anti-seepage curtain to solve the leakage risk.
5 technical advantages of high pressure jet grouting drilling rig
- Ultra-high pressure jet system. Equipped with a 35MPa pressure pump, the slurry cutting capacity is 2 times higher than that of traditional equipment, which is suitable for hard rock formation construction.
- Intelligent control system. The PLC control panel is used to preset the injection parameters to achieve unmanned continuous operation.
- Environmentally friendly and energy-saving design. The slurry recovery rate reaches 95%, reducing waste emissions and meeting green construction standards.
- Modular structure. The main engine, pump group, drill rod, and other components can be quickly disassembled and assembled, and the transfer efficiency is increased by 50%.
- Precise positioning system. With Beidou + laser dual positioning, drilling deviation is controlled within ±3 cm.
