Mud Drilling, Jet Grouting Drilling in One-Time Drilling Machine
1. This type of drilling rig is suitable for the construction of multi-pipe rotary jetting method with outer diameter of drill pipe 142;
2. It can show mud volume, air volume, ground pressure, rotation speed, lifting speed, lifting distance, step distance, swing angle, etc;
3. Printing part: able to print instantaneous mud volume, cumulative mud volume, instantaneous grouting pressure, lifting speed, hole bottom pressure, air pressure, airflow, hole cutting water pressure, and hole cutting water flow;
4. In order to prevent the drill pipe from falling into the hole, the upper and lower grippers are equipped. When the drill pipe is inverted, it is ensured that at least one of the upper and lower grippers can tighten the drill pipe. When the upper and lower grippers act together, it must be ensured that one of the two grippers tightens the drill pipe, and the other gripper or chuck can be opened;
5. Optional wireless transmission for monitoring and equipment control on the drilling rig, with a stable wireless transmission range of 200m to 300m;
Remark: It can be used for DG multi-tube after matching with drilling tools, high-pressure pump, and mixing system.
(1) Reinforcement foundations and cut-off water in gravel, sand, and cohesive soil.
(2) Used in a complex construction environment.
(3) Running in narrow construction space.
(4) Reinforcing the cut-off curtain at the circumscribed joint of an ultra-deep underground continuous wall.
(5)Fracture grouting for damaged cut-off curtains.
(6) Special-shaped grouted piles.
(7) Stabilization treatment of the foundations of bridges, shields, subways, pipelines, and other buildings.
(8) Underwater foundation reinforcement.
1. Mud Drilling, Jet Grouting Drilling in One-Time Drilling Machine can be equipped with high power and high flow XTB series foundation strengthening pump and automatic mixer.
2. Wireless transmission is optional to monitor and control the equipment on the drilling rig, and the wireless transmission range is stable within a 200m-300m radius.
3. In addition, Mud Drilling, Jet Grouting Drilling in One-Time Drilling Machine is also suitable for other processes.
