Application of GRUNDOPIT K in Erlau Germany
GRUNDOPIT K is a steerable bore rig for the trenchless installation of gas and water house connections up to OD 63 mm. The bore is carried out from out of a keyhole of only 60 cm Ø. The spoil is removed from the keyhole by a suction excavator to provide access to the main pipe. Then GRUNDOPIT K can be set up. The bore head and the drill rods are transported to the bore rig via "lift", automatically placed in bore direction and screwed together one after the other.
