Directional drilling machine DDM-4 is a complex of the equipment for trenchless lining of pipelines 160 mm in diameter with a horizontal directional drilling method.
Uniqueness of the drilling machine is it's design and the sizes allow to work both with a surface or from a ditch, and from a finished well 1,0-1,5 m in diameter. That is a necessity at a lining of additional communications in functioning engineering networks, or at the lining directly in basements of houses.
The entire machine in the complete set is transported in cargo "Gazelle" or mounted on the trailer 2.9x1.8 m in the size, up to 1.5 tons capacity. In last case there is no need for the car to be on the work site.
The drilling machine tool can be easily disassembled into pieces, transported and installed, even in finished well through the hatch.
Unlike foreign analogues, construction of the mud supply system makes low demands for water quality for the preparation of bentonite mud, usual water from a nearby reservoir is enough.
