"Emergency Bore" with the directional rod pusher TERRA-JACK TJA 125

Broken fresh water house connection -
A fresh water house connection in Brütten, Switzerland was broken. This made an emergency bore necessary with the directional rod pusher TERRA-JACK.

All in a hurry they opened a start and an arrival pit. The arrival pit was at the main water line. Then the TERRA-JACK made a directional bore for a new house connection in a length of 14 m (47 ft).

Pic 1: The start pit was opened near by the house, the TERRA-JACK was lifted into the pit and secured with wood. Then the pilot bore was done.

Pic 2: The drill head (push head) reaches the arrival pit right on target.

Pic 3: After the pilot bore the drill head is disassembled. An expander star, the expander cone and the new HDPE pipe are assembled.

Pic 4: The contractor has built a special trailer for their TERRA-JACK. It is completely equipped with all necessary accessories, not to lose any time in case of emergency bores.

Pic 5: The new pipe OD 50 mm (2") has been pulled in.

Pic 6: The old broken waterline was cut off from the main water valve. The new fresh waterline was connected.
