Advanced Pre-Support Tunnel Excavation Project Drilling and Jet Grouting Drilling Machine

Advanced Pre-Support Tunnel Excavation Project Drilling and Jet Grouting Drilling Machine

Sophisticated Pre-assist Tunnel Excavation Task Drilling and Jet Grouting Drilling Machine  

Software :
Xps-fifteen tunnel horizontal rotary jet drilling device is a particular products for advanced pre-assist of weak bottom layer such as wind-blown sand throughout tunnel building. Through rotary jet development technique, shut rotary jet pile curtain is formed just before tunnel excavation to avoid drinking water and sand fixation.The rig can also be equipped with diverse drill resources for slope catastrophe management, anchor bolt and other operations.

one, Electricity system: 183KW DEUTZ diesel generator established and 110KW motor. The motors can be pushed by mains 380V power offer and generator set respectively.

two, Walking system: metal crawler, with a observe width of 2800 and a chain plate width of 600, with a driving speed of 1-one.4km /h. The walking program is driven by a hydraulic motor, which is suitable for complex floor development.

3,  hydraulic method: the use of REXROTH, brevini, EATON and other world-renowned brands of hydraulic elements, the use of load-delicate control systems, electro-hydraulic proportional manage and other sophisticated systems, making the operation easy, efficient and reputable.

four, CZPTal control method: It adopts PLC centralized management and has features such as fault alarm, which is risk-free and trustworthy.

5,Operating method: it is geared up with wireless distant operator, which can recognize remote control. The principal working system is geared up with a exhibit, which can screen drilling depth, mast angle, rotation pace, feed and drag pace, system strain and other parameters

six,Structural elements: the rotating mechanism of the body, the two-arm support mechanism and the mast are built-in, and the structure is compact the two-arm help mechanism is two-phase lifting, the support is stable, keeping away from drift in deep hole operation, and the very first stage has a slewing system It can recognize ±120° rotation, can recognize porous operation in the exact same functioning aircraft, and enhance perform performance the mast is composed of three sections, both ends can be folded for effortless transportation the energy head has four-pace shifting, extensive speed variety and large torque. (Optional hydraulic impact electrical power head)The energy head stroke is 14m, and the size of the drill pipe is 15m. can be drilled into a gap and rotary jet into a pile.The hoisting equipment is utilised for feeding and returningThe gripper can add and hold drill pipe and shackle to lessen the labor intensity of employees.The entrance finish of the rear gripper is geared up with a return tow oil cylinder,whose stroke is 600mm and the pulling back again power is tons.When the drill stuck, it can be utilized with the winch to pull again.

seven,It is equipped with a foldable arm workbench, which is convenient for manned to function the orifice.

8,Equipped with a centralizer to decrease the swing of the drill pipe for the duration of drilling, and the drilling is stable and reliable.

nine, Rotary Jet Drill: 76 solitary-tube rotary spray, 89 double-tube rotary jet drill pipe attachment.

ten,With various drilling instruments, it can be utilized for anchor bolting, down-the-gap drilling and rock drilling.

eleven,It is outfitted with huge-stream large-circulation XTB collection floor-based mostly pump and ZDJ-1 automatic mixer.
