Abstract:
PURPOSE: To simplify construction and administration work by a method in which a number of screw anchors are attached to the periphery of the frame of crawler and an oil-pressure jack for penetrating pile is set on the central part of a penetrating base.
CONSTITUTION: A pile-penetrating base 5 is attached to the tip of a crawler frame 4, and both ends of tip of the base 5 are supported by a screw anchor 17. An oil-pressure cylinder 22 for penetrating pile is set on the central part of the base 5.
