A Horizontal Drilling Machine UGB-2M4 (GBM) is a new product of the NPK Gidrofob Remsvyazmontazh. The Machine UGB-2M4 (GBM) is intended for drilling horizontal and angular holes used in laying communication lines, water supply system, gas pipeline, cables of different purposes, when drilling is carried out under the motor roads at a distance up to 50m.
The Machine can also be used for drilling vertical holes up to 50m depths.
The Horizontal Drilling Machine UGB-2M4 (GBM) is in operating position:

Operation order with UGB-2M4 (GBM) when drilling angular and horizontal boreholes
The knocked-down Drilling Machine is brought to the place where the works are planned to carry out.
The main parts:
- Main frame;
- Drill jib with movable carriage;
- Oil station with controllers;
- Pump with hoses for dirty water;
- Drilling pipes with tools and accessories,
The Machine is assembled, anchored and prepared at the place where the works are planned to carry out.
If necessary to drill horizontal borehole in a ditch then the ditch 2.5mõ1.3m sized is excavated; and its depth must be 0.3m more than the depth of the borehole. The Machine is bottomed part by part and assembled there. After that two ditches 0.5mõ0.5m sized and 0.5m depth is excavated. The first ditch should be near the edge of the borehole, the second one should be excavated by 15-20cm father. The ditches are covered with polyethylene film to reduce the water loss during the drilling. The ditches should be connected among themselves by a small trench at the upper part.
The essence of the method is in the following: wastewater gets from the borehole to the first ditch where the soil carried by the water sinks. The treated water gets to the second ditch along the trench where is pumped by the pump, and then the water is pumped to the drilling zone through the water swivel at the Drilling Machine, drilling strings and drill head where it takes the soil particles and remove them from the borehole.
When the pilot hole is completed a pipe up to 76mm in diameter is pulled by the reverse motion without an additional enlargement.
If necessary to lay the pipe of larger diameter, then a proper reamer is attached and the borehole is enlarged.
When the enlargement is completed the pipe is pulled by the Machine.
Operation order with UGB-2M4 (GBM) when drilling vertical boreholes
When vertical drilling is carried out, the assembly and preparations of the machine are the same, except the fact that the drill head has larger diameter necessary for lowering-in a case pipe into a borehole. The drilling is carried out without further enlargement.
