We present the UM-20 directional pipe jacking machine with radio locating and steering system.
Technical features of the machine allow to make 60 m long pilot drills, pulling polyethylene pipes (PE), pulling short pipe modules, performing pipe bursting operations on pipes ranging from 32 to 200 mm in diameter. The machine can be used as a winch with a pulling force of 20 t, e.g. for pulling pipes into an existing pipeline.
We provide theoretical and practical training covering the operation of the machine and locating system.

SNS-2t Radio Navigation System
The SNS-2t Navigation System was introduced to the market in 2019 and is and improved version of the SNS-200 and SNS PROn navigation systems.
It is a reliable and precise navigation system for pipe jacking and directional drilling (HDD) 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 with a mini probe allows control at a depth of up to 8 m (with a large standard probe up to 35m). In the set: receiver, operator monitor, 12 kHz + 30 kHz per mille 0.1% probe with “drilling to target” feature.
Drilling technique for UM-20 Pipe Jacking Machine
The UM-20 machine can work in a trench or in an existing well starting with DN1000.
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 without using any drilling fluid, while pulling the pipe.
This method of hydraulic jacking is useful for installing pipes under roads and railways without interference with the traffic and the road surface. It easily overcomes small rivers or drainage ditches.
The precision of navigation is more than enough to install cables, pressure lines and even gravity sewers if the inclination is high enough, thanks to using a per mille 0.1% probe.
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 UM-20 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.
