DMS-130A multi-functional omni-directional micro-disturbance engineering drilling rig employs the IMS Method (In-situ Mixing System Method) - an innovative geotechnical technology specifically developed to address ground improvement challenges in complex urban environments. This method utilizes precision control and specialized equipment to achieve high-quality ground improvement while minimizing impact on surrounding structures. Capable of handling diverse ground conditions from soft soils to sand layers, it serves as an ideal solution for urban foundation improvement projects.
Applications
1. Environmentally Sensitive Projects - Ideal for sites with stringent environmental requirements, particularly near critical infrastructure including operational subway tunnels, heritage buildings, and sensitive pipeline networks.
2. Confined Urban Excavations - Excels in tightly constrained urban deep excavation projects, enabling construction of support structures and cutoff walls immediately adjacent to existing buildings.
3. Underground Space Development - Effectively applied for ground improvement at key locations such as tunnel portals and diaphragm wall joints in underground development projects.
Features
1. Unique Triple-Stage Drill Head - Combines serrated mixing bits, central free blades, and top mixing blades to minimize ground disturbance.
2. Precision Pressure Control - Utilizes natural slurry discharge channels and stable grouting pressure for smooth operation.
3. High-Accuracy Alignment - Maintains verticality tolerance within 1/200.
4. Lightweight Design - Reduced ground load enhances operational safety.
5. Broad Application Range - Maximum depth exceeding 25m with pile diameters from 600-2000mm.
6. Flexible Operation - Capable of drilling at angles up to 45° for specialized project requirements.
Advantages
1. Industry Recognition - Widely preferred in modern geotechnical engineering.
2. Minimal Disturbance - Effectively controls impact on adjacent structures, meeting stringent environmental standards.
3. Consistent Quality - Produces uniform columns with reliable reinforcement results.
4. Compact Flexibility - Adapts to confined sites, enhancing project feasibility.
5. Eco-Friendly Operation - Low vibration, reduced slurry discharge, and minimal environmental impact.
