AT - Drainage System

AT - Drainage System

The AT - Drainage System is used for deep reaching drainage and forms part of the AT - Casing System product family. It is used in Tunneling and in Civil Engineering for draining the surrounding ground and consists of an inner steel tube which is wrapped with a PVC-drainage pipe.

The AT - Drainage System can be applied temporarily as well as semi-permanently. Examples of application are drainage works parallel to tunnel advances or water saturated slopes.

Fields of Application

  • Far-ranging drainage works
  • Drainage with and without vacuum application
  • Drainage of the ground ahead of the advance and parallel to construction
  • Reduction of water pressure in fault zones ahead of construction
  • Stabilization of water saturated slopes
  • Reduction of the water pressure behind construction walls
  • Drainage works in all geological conditions

Main Advantages

  • Installation using conventional drilling machines
  • Execution of the drilling works can be carried out by on-site personnel guided by application engineers
  • Time-saving self-drilling installation thanks to simultaneous drilling and casing
  • Installation also possible in flowing ground conditions
  • Length of the drainage tubes adaptable to little space
