Crawler Drill Rig for Jet-grouting
The Crawler Drill Rig for Jet-grouting is suitable for DG multi-tube rotary grouting construction with a drill diameter of 142mm or less. It can show mud volume, air volume, ground pressure, rotation speed, lifting speed, lifting distance, step distance, swing angle, etc; 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; 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; Optional wireless transmission for monitoring and equipment control on the drilling rig, with a stable wireless transmission range of 200m to 300m; It is applied to various soil textures and can be constructed by vertical technology such as full rotation and swing jet grouting.
Remark: It can be used for DG multi-tube after matching with drilling tools, high-pressure pump, and mixing system.
1. Compact drill rig structure, combined with electric control and hydraulic control, it's convenient for operation.
2. High efficiency and low energy consumption by Direct-acting load feedback variable hydraulic system.
3. Accurate control of rotary jet lifting speed and stepping distance.
4. The power head adopts a two-speed hydraulic motor with stable rotation speed and large torque. The minimum rotation speed is 0.35r/min, which effectively improves the quality of the grouting pile; the through-hole spindle load that rob can be moving fast, which can meet the requirements of the DG multi-tube.
5. Any direction grouting drilling and any special-shaped pile.
6. Quick and accurate hole positioning by viewing the screen showing the verticality of the column and the horizontality of the frame.
7. Stepping type drilling rig is flexible operation and easy moving.
8. Reduce the working intensity of installing and dismouting by an auxiliary tower and winding engine.
9. Reasonable control system with PLC electronic control display, clear identification, and easy operation.
It can be applied to railways, highways, bridges, roadbeds, dam foundations, and other industrial and civil buildings, such as foundation reinforcement, water insulation and plugging engineering, soft foundation treatment, and geological disaster control.
1. Crawler Drill Rig for Jet-grouting 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, Crawler Drill Rig for Jet-grouting is also suitable for other processes.
