DGZ-150B Jet Grouting Drilling Rig Soil Mixing Consolidation Underpinning

DGZ-150B Jet Grouting Drilling Rig Soil Mixing Consolidation Underpinning

Introduction:

DGZ-150B drilling rig is suitable DG multi-tube rotary grouting construction with a drill diameter of 142mm or less. Load-sensitive hydraulic control systems and self-developed electronic control systems are adopted. The main hydraulic parts are from an international famous suppliers, which are stable and durable. The whole machine adopts the combination of hydraulic control and electric control, which is simple and flexible to operate, saving time. The compact structure design is easy for moving. It is equipped with a monitoring system. It is on the driller control coard that shows mud volume, air volume, ground pressure, rotating speed, lifting speed, lifting and stepping distance, and wing angle. The instantaneous mud volume, cumulative mud volume, instantaneous grouting pressure, lifting speed, pressure in the bottom of the hole, air pressure, airflow, cutting water pressure and cutting water flow, etc.

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.

Technical Data:

Application:

(1) Reinforcement foundations and cut-off water in gravel, sand, and cohesive soil.

(2) Used in a complex construction environment.

(3) Running in a narrow constuction 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.

Main Features:

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.
