Multi-Functional Engineering Drilling Rig for Tunnel Applications
DMS-50C-II multi-functional drilling rig employs the TJS Method (Tunnel-based Jet Grouting System with Omni-directional Micro-disturbance) an advanced ground improvement technology specifically developed for tunnel engineering. It is particularly suitable for reinforcement and defect improvement in soft soil strata. Through high-pressure jet grouting performed inside the tunnel, this method forms high-quality cement-soil reinforcements, enabling precise strengthening and restoration of tunnel structures. The TJS Method has become a vital technical solution in the field of tunnel engineering reinforcement and remediation.
Applications
1. Full-Lifecycle Service - Supports all phases of tunnel projects from construction to maintenance.
2. Settlement Control - Effectively manages settlement and corrects deviations during tunnel construction.
3. Cross Passage Reinforcement - Serves as an efficient alternative to conventional freezing methods for connecting passages.
4. Operational Maintenance - Precisely rectifies settlement and deformation in operating tunnels to ensure long-term safety.
5. Compact Applications - Suitable for confined spaces in urban underground projects due to its compact design.
6. Versatile Reinforcement - Capable of multi-directional reinforcement (horizontal/vertical/inclined) with 1,200mm diameter and 20m depth capacity.
Features
1. Micro-Disturbance Control - Precisely manages ground pressure through accurate spoil discharge control, minimizing impact on surrounding soil and tunnel structures.
2. Compact Tunnel Design - Specifically engineered for confined spaces like tunnel interiors, overcoming traditional equipment access limitations.
3. Fully Integrated System - Combines grouting and spoil discharge processes into a unified operation, significantly improving construction efficiency.
Advantages
1. Minimal Disturbance - Significantly reduces impact on tunnel structures and surrounding environment, ensuring project safety.
2. High Efficiency - Allows simultaneous multi-unit operation, substantially shortening construction schedules.
3. Cost-Effective - Offers superior economic benefits compared to traditional methods.
4. Consistent Quality - Creates uniform, high-strength reinforcements with durable and reliable performance.
