In a device that moves forward together, the tip of the excavator enters the old pipe, crushes it and expands the gap to replace the old pipe with the new pipe. A device for replacing an old pipe with a new pipe, characterized by expanding the diameter by forming at least two or more different inclination angles with respect to an axis.
