The MGL - 155D type crawler-mounted deep foundation anchoring cobble machine is an efficient cobble machine developed by Wuxi Banshan Construction Machinery Manufacturing Co., Ltd. based on the needs of domestic subway, high-rise buildings, airports, ground source heat pumps and other deep foundation projects for anchoring, jet grouting and dewatering.
Main features:
1. The maximum rotational speed can reach 170 revolutions per minute, which is 20% higher than that of MGL - 135D. This significantly improves the efficiency when using twist drills and in soft soil conditions.
2. Energy-saving and highly efficient; without an increase in power, it effectively enhances work efficiency.
3. As the rotational speed increases, the torque has increased by 10% compared to MGL-135D, and the maximum torque has risen to 7500 NM.
5. A new type of hydraulic system has been adopted, which has a simpler structure, a more reasonable layout and a more user-friendly operation.
3. Compared with the previous model, the MGL-135D drilling rig has achieved a construction efficiency increase of approximately 20%. The torque and rotational speed can be reasonably matched according to actual needs. The traveling frame's stroke is 3.4 meters, allowing for the simultaneous advancement of drill rods and casing, and it can perform composite drilling of 3 meters using cobalt rods. Different torque rotary devices can be configured according to different geological formations, enhancing the rig's adaptability. Equipped with a crawler chassis, a high-position rotating platform, large-diameter leg oil cylinders, a 0.9-meter sliding frame, and a hole opening support device, the drilling rig is extremely convenient for relocation and positioning, and is stable and reliable during drilling. It is equipped with a clamping unloader, reducing the labor intensity and increasing the efficiency of loading and unloading drill rods and casing.
4. The entire machine is driven by an automatic rotating hydraulic system, eliminating the need for manual labor and making it more convenient and effortless. 7. The tracks are modeled after those of a small Komatsu excavator chassis, and are equipped with brakes, ensuring more reliable climbing performance of the machine.
The research and development has equipped corresponding cobble tools, which can meet the following construction techniques:
1. Three-wing cobble head cobble insertion, with slurry discharge. Suitable for high-speed cobble insertion in soil layers and other strata.
2. Air-driven core drill for penetration, with air for slag removal, suitable for rock strata and fractured layer construction openings. 3. Bottom-of-hole hydraulic hammer for penetration, with slurry for slag removal. Suitable for fractured layers, sandy conglomerate layers and other layers with high water content for construction.
4. Casing drilling. 5. Drilling with a combination of drill rods and casings. 6. Rotary grouting techniques such as single-layer, double-layer, triple-layer, fixed-grouting, and swinging-grouting.
