Method and device for inserting pipes into the soil

摘要

The method involves vibrating a pipe (2) by vibrators (1). Vibrations of the vibrators are transferred to the pipe such that the pipe is rotated additional to linear movement for causing screw thread like oscillation of the pipe. The pipe is elliptically moved on a pipe wall during the screw thread like oscillation. Shafts of the vibrators receive unbalanced masses and are aligned at a center point of a circular cross-section of the pipe. The shafts are rotated relative to each other in a same direction. The vibrators are designed such that continuous centrifugal force is produced. An independent claim is also included for a device for inserting a pipe into soil.
