UNBEATABLE OVER SHORT DISTANCES.

 

BOHRTEC

THE INSTALLATION OF SEWAGE DUCTS AND PIPELINES in densely built-up cities as well as crossing beneath infrastructure elements must be completed with great precision, efficiency and environmental sensitivity. Bohrtec offers space-saving, user-friendly drilling equipment to lay underground pipelines with small diameters. It can precisely install pipes with lengths of up to 120m. To ensure a project progresses smoothly, Bohrtec supports its contractors in both the planning and execution phase with comprehensive services and special solutions.

More than 300,000 meters of pipeline for instance for sewage ducts

have been successfully installed around the world using Bohrtec Auger Boring Machines.

 

Products

THE EFFICIENCY AND ECONOMY of Bohrtec Auger Boring Machines become particularly obvious on short drives. New pipes and connections to existing pipes can be created safely underground with no impact on life on the surface. The machines’ robust design, simple assembly and easy operation prove their value every day in the tough reality of construction sites. The Auger Boring Machines can be equipped with various, project-specific additional equipment, enabling them to operate in a wide range of projects and geological conditions.


Compact machines
  • Guided or non-guided operation
  • Minimal shaft dimensions in inner-city projects
  • Drills of up to 100m in length
  • Exterior pipe diameters from 100mm to 1,000mm
  • Drills can be carried out from within existing pipes (larger than 1.20m)

Compact machines for drilling in confined construction site conditions.


LONG-FRAME MACHINES
  • Guided or non-guided operation
  • Installation of up to 18-m-long steel pipes thanks to a modular extendable frame construction
  • Drills of up to 120m in length
  • Exterior pipe diameters from 200mm to 1,400mm
  • Special applications such as pipe arches

Long-frame machines for drilling with diameters up to 1.4m.


FRONT STEER
  • Pilot drills in non-displaceable soils and rock up to 10MPa
  • Millimeter precision drilling with optical surveying system
  • Steel pipe drills with inclinometer and hydrostatic water level
  • Non-system dependent use with existing drilling systems and augers for steel pipe installation

Bohrtec’s patented Front Steer for pilot drills in non-displaceable soils.


HOLE OPENER
  • Precise installation of plastic pipes as gravity lines
  • Drills up to 120m in length and with diameters up to 800mm
  • Attachments of various sizes mean easy use for various pipe diameters



The Hole Opener can be used to lay plastic pipes of various diameters.
