PRESTRESSED STEEL PIPE PILE
PROBLEM TO BE SOLVED: To provide a prestressed steel pipe pile having high flexural rigidity while having a small diameter.SOLUTION: A prestressed steel pipe pile includes: a binding pipe 10 that has both ends opened; two cap parts 20 capable of closing both the ends of the binding pipe 10; a consolidation material 30 that is enclosed within the binding pipe 10; and a tension member 40 that has an overall length enabling insertion of the binding pipe 10. A reaction force is applied to the cap parts 20 to tension the tension member 40, and the consolidation material 30 is bound by the binding pipe 10 while prestress is applied to the binding pipe 10.SELECTED DRAWING: Figure 1
【課題】小口径でありながら高い曲げ剛性を有する、プレストレス鋼管杭を提供する。【解決手段】プレストレス鋼管杭は、両端を開口した拘束管１０と、拘束管１０の両端を封鎖可能な、２つのキャップ部２０と、拘束管１０の内部に封入した、固結材３０と、拘束管１０を挿通可能な全長を有する、引張材４０と、を有し、キャップ部２０に反力を得て、引張材４０を緊張して、拘束管１０にプレストレスを付与しつつ、拘束管１０で固結材３０を拘束したことを特徴とする。【選択図】図１
