METHOD AND APPARATUS FOR THE PRODUCTION OF UNDERGROUND PIPELINES

摘要

Method and apparatus for producing underground pipeline containing head part (3) with cutting (17) rotating tool or hammering tool, loosened soil is transported out of tunnel with transportation drum (1) which contains spiral (2). Drum (1) is supported by roll device (13) (14) against pipe (8). Rotating movement is transmitted to rotating drill head (3) from transportation drum (1), which is driven by motor (27). Cylinders (28) are pushing whole the system and force is transmitted by outer pipe (8) to head part (3) and guiding of head part (3) is done by cylinder (9). Entering and direction of head part (3) is observed through free opening of transportation drum (1).
