Full Hydraulic Jet Grouting Drilling Rig

This fully hydraulic jet grouting drilling rig is ideally suited for high-intensity operations, including ultra-deep foundation pit support, large-scale landslide remediation, the installation of anchor bolts and cables on steep slopes, subgrade reinforcement for high-speed railways and highways, and seepage control reinforcement for hydroelectric dam bodies. Its combination of high torque and a large-diameter gripper allows it to perfectly handle drilling requirements in complex geological conditions-such as hard rock, pebble layers, and fractured zones.

It supports specialized construction processes such as large-diameter micropiling, high-pressure jet grouting for water cutoff, pilot hole drilling for curtain grouting, and casing-following drilling. This capability meets specific operational demands for water cutoff in urban deep foundation pits, soft soil foundation reinforcement, and seepage prevention in underground engineering projects.

Equipped with a remote-control travel function, the rig is adaptable to hazardous work environments where human access is difficult-such as emergency response to geological disasters, remediation of high-risk slopes, and tunnel portal support. Furthermore, it can be flexibly maneuvered and relocated across complex terrains, including mountainous areas, muddy ground, and confined workspaces.

A single machine covers a wide spectrum of construction needs-including anchoring, pilot hole drilling, and piling-across various sectors such as municipal engineering, transportation, water conservancy, and energy. It is particularly well-suited for general contractors and specialized anchoring teams managing multiple concurrent projects, thereby effectively reducing the costs associated with redundant equipment investment.

The load-sensing hydraulic system delivers oil on demand; compared to standard fixed-displacement systems, it reduces fuel consumption by over 20% and eliminates redundant power loss during operation. It offers high control precision, ensuring smooth adjustment of pressure and rotational speed during drilling. With minimal hydraulic component shock, the system's overall service life is extended by 30%, resulting in a significantly lower failure rate.

The wireless remote control for machine travel boasts an effective range of up to 100 meters and strong anti-interference capabilities. For operations in hazardous environments, personnel are not required to board the machine, thereby completely eliminating risks such as machine slippage or falling rocks. The hydraulic control interface features moderate damping and simple logic, making it easy to master quickly and minimizing operator fatigue during prolonged use.

The high torque output of 30,000 Nm allows for the effortless crushing of hard rock formations with compressive strengths up to 200 MPa, while the high rotational speed of 163 rpm significantly boosts drilling efficiency in soft soil strata. The large-diameter gripper (530 mm) supports hole-forming operations with diameters up to 500 mm and is compatible with large-diameter casing-following construction methods, providing a perfect solution for the challenges of drilling in complex geological formations.

Capable of accommodating over 10 mainstream construction techniques without requiring any additional modifications, this machine truly achieves "one machine, multiple uses." It reduces the capital investment in specialized equipment by at least 30% and ensures high efficiency in site transfers and technique switching, thereby substantially shortening the overall project preparation cycle.
