Anordnung zum Vortrieb eines Tunnel- oder Abwasserrohrs
摘要
The invention relates to a device for driving a tunnel or drain pipe along a stretch (14) leading from a starting shaft (10) to a target shaft. The device is primarily intended for making micro or mini-tunnels in which pipe sections (62) are pressed one by one into the drive stretch against a frontal driving head (16). For spoil (32) removal there is a worm conveyor engaging in the cutting chamber (26) of the drive head, to the discharge end of which can be fitted in succession a pressuretightly sealable stone trap (36) and the pressuretightly sealable intake side (42) of a thick matter pump (44), while the pressure side of the thick matter pump (44) is connected to an extendable conveyor line (56) for the spoil.
