YG’s high-pressure jet grouting drilling rig is designed for foundation reinforcement, anti-seepage curtain, foundation pit support, and other projects under complex geological conditions. From the appearance, it usually adopts a crawler or wheeled chassis to enable flexible movement on the construction site. The main body of the equipment includes a sturdy mast (or guide rail) to support and guide the drill; a powerful power head to provide rotation and impact force; and a set of precise feeding/lifting systems to control the movement speed and position of the drill in the hole. In addition, a complete jet grouting system also requires supporting high-pressure grouting pumps, mixers, and other equipment, which usually work in conjunction with the drilling rig. YG’s drilling rig is made of high-strength steel, and key components are precision machined and heat-treated to ensure stability and durability under long-term high-load operations.

Features and Technical Parameters of Jet Grouting Drilling Rig
- Various drilling modes: Supports multiple drilling modes such as rotary and impact rotary, and can effectively penetrate different soil and rock layers.
- High torque power head: Provides strong rotational torque to ensure smooth drilling in clay, sand, gravel, and even some soft rock formations.
- Precise feed/lift control: An advanced hydraulic system and control unit are used to precisely control the drill’s speed and position in the hole, which is the key to forming a high-quality grouting body.
- Adjustable mast angle: The inclination angle of the mast (drilling tower) is adjustable, which is convenient for the construction of vertical or inclined holes and meets different engineering design requirements.
- Compact and flexible design: Compared with large rotary drilling rigs and other equipment, jet grouting drilling rigs are usually more compact and easier to operate in urban environments or complex construction sites with limited space.
- Powerful supporting capabilities: It can be used with various types of high-pressure grouting pumps, mixers, etc., to form a complete jet grouting workstation.
Application Fields and Cases of Jet Grouting Drilling Rig:
- Soft foundation reinforcement: In the foundation construction of new high-rise buildings, bridges, industrial plants, and other projects, it is used to treat silt, plain fill, loose sand, and other strata to form bearing piles or reinforcement areas.
- Deep foundation pit support and water stop: In the excavation of deep foundation pits such as urban subways, underground spaces, and basements of large buildings, it is used to form underground continuous walls as support or water stop curtains to ensure excavation safety.
Case: In the construction of a subway station in a city in Southeast Asia, the construction party used YG’s jet grouting drilling rig to quickly build a continuous water stop curtain in the soft soil stratum, effectively controlling groundwater leakage and ensuring stable excavation of the foundation pit. - Tunnels and underground projects: Before or during tunnel excavation, the soil around the face or tunnel is pre-reinforced to improve the stability of the surrounding rock and prevent landslides.
- Water conservancy projects: In projects such as dams, sluices, and reservoirs, it is used to form anti-seepage curtains to reduce leakage.
Case: A hydropower station dam in South America was renovated for anti-seepage. The YG compact jet grouting drilling rig was used to successfully form a continuous anti-seepage wall in the complex geological area of the dam foundation, significantly improving the safety of the dam. - Renovation and maintenance of old structures: Strengthen the foundations of existing buildings, bridges, etc., to extend their service life.
