high-pressure jet grouting drilling rig for foundation

High-Pressure Jet Grouting Drilling Rig

This high-pressure jet grouting drilling rig is a new type of advanced equipment that integrates an intelligent system and self-drilling functions. With a height of 33.8 meters, the rig utilizes modular combinations to flexibly achieve various construction techniques such as fixed jet, swing jet, and rotary jet grouting, making it suitable for ground treatment and reinforcement projects in complex geological environments.

Main Features of the High-Pressure Jet Grouting Drilling Rig

1. Supports continuous drilling up to 30 meters with a single drill rod, eliminating the need for mid-operation connections, which greatly improves efficiency, saves materials, and reduces quality risks.
2. Standardized structural design allows gantry components to be interchanged between towers, enhancing equipment compatibility.
3. Upgraded high-torque power head enables large-diameter jet grouting construction, compatible with super jet grouting rods, and allows for self-drilling and jetting in most strata.
4. Automated control system: the main hoist automatically follows the power head, and rods are automatically guided after each stroke, reducing manual intervention and improving stability and efficiency.
5. The anti-overturning structure, optimized by finite element analysis, significantly enhances the rig’s stability and safety under challenging working conditions.
6. Equipped with an intelligent construction data management system, supporting real-time recording and inquiry of up to 11 key construction parameters such as grout pressure, grout volume, lifting speed, rotation speed, etc., which facilitates cost control and quality traceability.

Application Fields

1. Jet grouting reinforcement of weak foundations.
2. High-pressure jet grouting cut-off walls.
3. Basement seepage control for high-rise buildings.
4. Dam seepage control or reinforcement.
5. Foundation reinforcement for highway and railway bridge piers.
6. Large-diameter jet grouting pile construction.
