Elevated Jet Drilling Rig

The MDL-150D8 multi-function drilling rig is a new multi-function self-drilling rig developed by RM based on the existing MDL series drilling rigs, taking into account the construction sequence of foundation engineering jet grouting, anchoring, and anti-floating anchor rods.

You can rest assured to buy overhead jet grouting drilling rigs from our factory, and RM will provide you with the best after-sales service and timely delivery.

Main uses:

1. Soft foundation treatment 

2. Water-stop curtain 

3. Drilling hole construction

Main features of the elevated rotary jet drilling rig:

1. A detachable 12-meter auxiliary tower is installed

● During rotary jet construction, it can replace the elevated rotary jet, reduce the number of drill tool disassembly, save time and materials, and reduce quality risks.

● During the construction of anti-floating anchor rods, the anchor rods can be lifted, saving the cost of the crane.

● The detachable auxiliary tower can be disassembled during the construction of inclined anchor cables without affecting other functions of the drilling rig.

● During the construction of short anchor rods, one rod can be used to the end, saving time and effort.

2. Large through-hole rotator

● The through-hole diameter is 92mm, and the 89 drill rod can pass smoothly. It can achieve triple rotary jet construction and anchoring construction.

● Ordinary 89 steel pipes can also be used for anchoring construction.

● The hydraulic chuck structure allows the replacement of drilling tools to be convenient and free. No need to worry about replacing transition joints.

●The high torque power head, combined with our enhanced jet grouting drill, can be used in most strata for jet grouting construction without the need for a pilot hole, saving a lot of cost and time.

3. Track travel

The elevated jet grouting drill uses a track chassis with a large ground pressure ratio. It can move freely even on soft ground.

4. Orifice guide device

●During jet grouting construction, the drill can be easily disassembled, while achieving the construction angle and verticality.

●During anchor construction, the force of the steel pipe can be improved, and the construction accuracy is high.

●The rotation mechanism of the orifice can reduce the wear on the cobalt tool.
