Device for drawing out pipe embedded in solid material - has wall abutment plate and draw element guided through pipe |
摘要 |
The machine for drawing a pipe out of solid material using an abutment plate containing a pipe passage opening has a drawing element (13) guided through the pipe (2) whereby a compressive force acting in the axial direction on the pipe (2) can be applied. The drawing element, such as a cable or a multi-sectional tensile rod, is connected to two pressure elements (14 to 20, 21) each acting on one end of the pipe (2). ADVANTAGE - The danger of the emerging pipe splitting is substantially reduced owing to the compensating force acting inside the pipe.
