Product Description
MJS Method Omni-Directional Intelligent Jet Grouting Drilling Rig
Product Description
Model DFJ-150, DFJ-150A, DFJ-220A are our hottest-selling MJS Method jet grouting drilling rigs. Compared with conventional jet grouting rigs, it offers significant advantages. In other words, it is omni-directional micro-disturbance super jet drilling rig.
MJS Method (Metro Jet System Method) is an advanced ground improvement technology that has been innovatively upgraded based on the introduction and assimilation of international advanced technologies, combined with domestic engineering practice requirements. Through its unique active pressure control system, this method enables micro-disturbance construction in various complex environments and has become an important technical solution for ground treatment in urban sensitive areas. Dunyu Heavy Industry MJS Method has become a preferred solution for ground improvement in complex urban environments. It has achieved remarkable application results in metro projects in cities such as Shanghai, Guangzhou, Nanjing, Wuhan, and Hangzhou, demonstrating excellent technical performance and reliable product quality.

Applications
1. Critical Waterproofing - Widely used for constructing cutoff walls in metro tunnels and utility tunnels, performing exceptionally well in sensitive areas adjacent to operating subways, important structures, and dense utility networks.
2. Omni-directional Construction - Capable of executing vertical, horizontal, and inclined drilling with equal proficiency.
3. Proven Ground Adaptability - Achieves maximum reinforcement depth of 60 meters, forming high-quality reinforcement in various ground conditions, including gravel, sand, and soft rock.
Features
1. Real-Time Ground Pressure Control - Utilizes a unique monitoring system with sensors at the drill head to track formation pressure changes, ensuring precise construction control.
2. Active Pressure Management - Equipped with specialized multi-channel drill rods and forced spoil discharge to prevent surface heave and ground disturbance.
3. High-Capacity Jet Grouting - Powerful single-nozzle system delivers 40MPa jet pressure with coaxial air shielding, creating uniform piles up to 2.5m in diameter.
Advantages
1. Minimal Disturbance - Significantly reduces impact on the surrounding environment, ensuring the safety of adjacent structures.
2. Proven Quality - Creates uniform piles with reliable strength (≥1.5MPa).
3. Eco-Friendly Operation - Centralized slurry treatment minimizes site pollution.
