Industrial complex for trenchless construction of underground utilities on the basis of horizontal directional drilling HDD 8000

Industrial complex for trenchless construction of underground utilities on the basis of horizontal directional drilling HDD 8000

The industrial complex is designed to perform the following operations:

  • construction of new pipelines in hard-to-reach urban housing;
  • installation of casings under the road surface without traffic disruption, passing under the small rivers and ponds, through wetland;
  • nontrunk laying of pipelines, diversion from the main pipeline;
  • installation of communication lines, including fiber-optic, gas pipelines and fuel lines installation.

The complex structure (Technical specification):

  1. Drilling rig
  2. Power plant with a pumping unit;
  3. Mixing device (high-pressure pump FMC or Speck);
  4. Barrel mud (as a single unit on the basis of its own);
  5. Kit anchoring device for drilling from the surface *;
  6. Positioning system of the drill bit (radar system) *;
  7. Set of drilling tools and accessories *;
  8. Set of drill rods *;
  9. Set of hoses with quick couplings;
  10. The water filtration system and drilling mud;
  11. Performance control.

* options and sets are formed when ordering
