Jacking of steel and product pipes. Continuous removal of soil by augers. Installation of casings by base machine and extension frames.
Towing Method

Jacking of reusable steel casings with simultaneous removal of soil by augers, followed by pushing in product pipes without sockets but with identical outside diameter. Recovery of the steel casings in the target pit.
