PILE LOADING TEST METHOD AND PILE LOADING TEST DEVICE
To economically carry out a pile loading test using a steel pipe pile with a tip blade that has a pile body and a bladed rotating portion that has an excavation blade and fits into the tip of the pile body.SOLUTION: A pile loading test method using a steel pipe pile with a tip blade, which includes a pile body and a bladed rotating portion that has an excavation blade and fits into the tip of the pile body, comprises a step of connecting a construction jig inserted inside the pile body to the bladed rotating portion, a step of driving a steel pipe pile with a tip blade to a predetermined depth by press-fitting the pile body into the ground while transmitting rotational torque from the construction jig to the bladed rotating portion to rotate and penetrate the bladed rotating portion into the ground, and a step of applying a vertical load or a tensile load to a bladed rotating portion.SELECTED DRAWING: Figure 5
【課題】杭本体と、掘削羽根を有し杭本体の先端部に嵌合する羽根付き回転部とを備える先端羽根付き鋼管杭を用いて、杭の載荷試験を経済的に実施する。【解決手段】杭本体と、掘削羽根を有し杭本体の先端部に嵌合する羽根付き回転部とを備える先端羽根付き鋼管杭を用いた杭の載荷試験方法であって、杭本体の内部に挿入される施工治具を羽根付き回転部に連結する工程と、施工治具から羽根付き回転部に回転トルクを伝達して羽根付き回転部を地中に回転貫入させながら、杭本体を地中に圧入することによって先端羽根付き鋼管杭を所定の深さまで打設する工程と、羽根付き回転部に鉛直荷重または引張荷重を加える工程とを含む杭の載荷試験方法が提供される。【選択図】図５
