STEEL PILE AND CONSTRUCTION METHOD FOR IT

摘要

PROBLEM TO BE SOLVED: To increase the tip bearing force and peripheral surface friction force of a pile by jointly using a steel pipe having a projection, a vibro-hammer, a water jet, and a flowing solidifying material. SOLUTION: This construction method of the steel pile includes: a first process of driving the steel pile with a projection into a load bearing layer by the vibro-hammer while water is injected; a second process of injecting water or a fluid solidifying material and also pulling out the steel pile; and a third process of driving the steel pile again into the load bearing layer while water or the fluid solidifying material is injected, wherein the continuous second process and third process are performed one or a plurality of times.
