DGZ-158B drilling rig is suitable DG multi-tube MJS rotary grouting construction with a drill diameter 142mm or less. Load-sensitive hydraulic control system and self-developed electronic control system are adopped in. The main hydraulic parts are form international famous supplier, 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 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,wing angle.The instantaneous mud volume, cumulative mud volume, instantaneous grouting pressure, lifting speed, pressure in the bottom of the hole, air pressure, air flow, cutting water pressure and cutting water flow,ect..
It is applied in 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 MJS 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) Adoped in complex construction environment
(3) Running in narrow constuction space .
(4) Reinforcing the cut-off curtain at the circumscribed joint of ultra-deep underground continuous wall
(5)Fracture grouting for damaged cut-off curtains.
(6) Special-shaped grouted piles.
(7) Stabilisation treatment of the foundations of bridges, shields, subways, pipelines and other buildings
(8) Subfluvial layer strengthening.
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 spindlelead that rob can be moving fast, which can meet requirements of the DG multi-tube in MJS construction.
5.Any derection grouting drilling and any special-shaped pile;
6. Quickand accurate hole positioning by viewing screen showing verticality of the column and horizontality of the frame.
7.Stepping type drilling rig is flexible operation and easy moving.
8. Reduce working intensity of installing and dismouting by auxiliary tower and winding engine.
9.Reasonable control systemwith PLC electronic control display, clear identification and easy operation.
