Abstract

PURPOSE: To obtain the means for drawing out and pressing in the steel pipe and the like whereby the deformation of the pipe is made to be conical to receive the force in the axial direction with a broad plane and to disperse the force and thereby the large force in the axial direction can be applied to the pipe.
CONSTITUTION: On the occasion of the work for pressing-in, the pipe 1 is positioned in a fastening band 2 of a crane and the like and, after that, the fastening band 2 is fastened by oil-hydraulic cylinders 3a and 3b for fastening. An oil-hydraulic cylinder 5 for elevation is contracted, the pipe 1 is pressed in the ground by one stroke of the oil-hydraulic cylinder 5 by means of the fastening band 2 and this action is repeated. On the occasion of the work for drawing-out, the pipe 1 is fastened by contracting the oil-hydraulic cylinders 3a and 3b for fastening and, after that, the cylinder 5 for elevation is extended, thereby the fastening band 2 is pushed up to draw out the pipe 1 by one stroke, and this action is repeated.
