METHOD FOR DRIVING STEEL PIPE PILE, AND SCREW TYPE STEEL PIPE

摘要

PROBLEM TO BE SOLVED: To create a safe, low-cost and easy-to-construct steel pipe pile by integrating a preceding steel pipe and a following steel pipe together as the steel pipe pile with a prescribed length by a screw joint through the use of a steel pipe as a steel material to be used along with construction work in place of an inhibiting pile with heavy weight and low strength. SOLUTION: The steel pipes 13 and 13a are integrated together in a full-rotation-type all casing device 9 by an accompanying crane 12 via a screw; inner excavation and earth removal are performed by means of the accompanying crane 12 via an excavating grab 17; and an anti-rotation pin 20a prevents excessive rotation and corotation. Embedment is efficiently performed with sufficient strength and light weight, and the steel pipe pile is driven in an extremely efficient manner with good working efficiency, safety and low costs.
