CONCATENATED TYPE BEARING PILE, AND METHOD FOR BURYING, DISMANTLEMENT, REMOVAL OF THE CONCATENATED TYPE BEARING PILE

PROBLEM TO BE SOLVED: To provide a concatenated type bearing pile which enables concurrent burying of a bearing pile and a drain member, and a method for burying, dismantlement, and removal of the concatenated type bearing pile.SOLUTION: A concatenated type bearing pile has a hollow cylindrical profile, and includes a body portion 2 and a tip portion 3. A drain member 4 is arranged on the outer circumferential surface of the body portion 2. The tip portion 3 includes a cylindrical portion 31 having a hollow cylindrical profile, a supporting portion 32 for supporting underground the body portion 2 at the bottom end of the cylindrical portion, and a boring portion 33 for boring soil at the bottom end of the supporting portion. The bottom end of the body portion 2 is inserted into the cylindrical portion 31 of the tip portion 3. The body portion 2 and the tip portion 3 are connected by connection devices 6, 7 which are respectively arranged on a bottom surface of a bottomed cylinder of the tip portion 3 and the bottom end of the body portion 2.SELECTED DRAWING: Figure 1 【課題】簡単な構成により支持杭とドレーン材の埋設を同時に行うことができる連結型支持杭並びにその連結型支持杭の埋設、解体及び撤去方法を提供する。【解決手段】 本発明の連結型支持杭は、中空円筒状の外形を有し、その外周面にドレーン材４が設けられた本体部２と、中空円筒状の外径を有する円筒部３１、該円筒部の下端に本体部２を地中で支持するための支持部３２、該支持部の底面に土を掘削するための掘削部３３を有する先端部３とを備えており、先端部３の円筒部３１内に本体部２の下端が挿入され、先端部３の有底円筒内の底面と本体部２下端にそれぞれ設けられた連結装置６、７により本体部２と先端部３が連結されている。【選択図】図１
