Product characteristics

MNB-50 multifunctional drilling rig with radio locating system (option).

Technical features of the machine allow to make 120 m long pilot drills, pulling polyethylene pipes (PE), pulling short pipe modules, performing pipe bursting operations on pipes ranging from 32 to 350 mm in diameter.

The standard set includes 40 pcs. of 970 mm rods (40 meters), hydraulic power pack, reamers and pullers.

We provide theoretical and practical training covering the operation of the machine and locating system.

It is possible to power the machine from an excavator (option without Power Pack).

Additional downsized trench boxes are available. L = 2000 mm or 1500 mm.

SNS-2t Radio Navigation System

The SNS-2t Navigation System was introduced to the market in 2018 and is and improved version of the SNS-200 and SNS PROn navigation systems.

It is a reliable and precise navigation system for directional drilling with multilingual documentation and interface.

The directional control in drilling is accomplished through placement of impulse generator in the drilling head. The impulse generator transmits the position, rotation, and inclination of the drilling head in real time.

SNS-2t navigation ensures drilling control at depths of up to 25 m.

Drilling technique for UM-20 Pipe Jacking Machine

The MNB-50 machine can be placed in a rectangular pit.

The first step is pilot drilling, which is accomplished by pushing drilling rods into the soil while controlling the direction with SNS navigation.

Next, the hole is expanded as required by pulling a series of reamers.

Finally, a new pipe is pulled into the hole.

This method of hydraulic jacking is useful for installing pipes under roads and railways without interference with the traffic and the road surface.

The precision of navigation is more than enough to install cables, pressure lines and even gravity sewers if the inclination is high enough.

This technology does not require using any drilling fluids therefore it can be applied in minus temperatures.

The advantages of hydraulic pipe jacking are simplicity, lack of vibration, very small size of excavation and negligible disruption of the surrounding area. The fact that no drilling fluid is necessary makes this method both ecological and robust in low temperatures.

Replacement of existing pipelines

The MNB-50 machine can also be used to replace fracturable old pipes by static pipe bursting, or by pulling a new pipe of smaller diameter into an existing old pipe.
