PROCEDURE

THE PILOT HOLE

A start pit is produced and the remotely controlled drill tool is advanced underground. High pressure drilling suspension is emitted from the threedimensional drill tool, which rotates through the ground forming the pilot hole or tunnel. Larger spoils are pressed against the walls of the tunnel and finer particles of earth are transported along the tunnel with the aid of the environmentally safe drilling fluid, to the start pit or the target pit.

WIDENING THE PILOT HOLE

The remotely controlled rotating drill tool reaches the target pit with complete accuracy, the relevant reamer for the job is then attached and the pilot hole is widened to enable the simultaneous installation of the product.

INSTALLING THE PRODUCT

The product (pipe or cable) is attached directly behind the reamer. The Bentonite drilling suspension enables the installation to be carried out smoothly and without damaging the product. This drilling suspension acts as a lubricant and helps to reduce friction in the tunnel.
