JOINT FOR UNDERPINNING METHOD AND UNDERPINNING METHOD USING THE JOINT
PROBLEM TO BE SOLVED: To provide a joint for an underpinning method which can firmly and easily connect steel pipe piles.SOLUTION: The joint for an underpinning method 20 according to the present invention has a flange portion 22 located at the center portion and projecting outwardly and a fitting cylinder portion 24 which is cylindrical and protrudes on both sides of the flange portion 22 and which can be press-fitted into the steel pipe pile 14 to be connected. Both fitting cylinder portions 24 are formed in a small diameter portion 24a whose front end side is reduced in diameter and the base portion side is formed in a large diameter portion 24b slightly larger in diameter than the inner diameter of the steel pipe pile 14 to be connected, and a through hole 26 or a recess is formed in the large diameter portion 24b.SELECTED DRAWING: Figure 5
【課題】鋼管杭の接続を強固、かつ容易に行えるアンダーピニング工法用継手を提供する。【解決手段】本発明に係るアンダーピニング工法用継手２０は、中央部に位置して外方に突出する鍔部２２と、該鍔部２２の両側に円筒状に突出し、接続すべき鋼管杭１４内に圧入可能な嵌合筒部２４を有し、該両嵌合筒部２４は、先端側が小径にすぼまる小径部２４ａに形成され、基部側が、接続すべき鋼管杭１４の内径よりも若干大径の大径部２４ｂに形成されると共に、該大径部２４ｂに、透孔２６もしくは凹部が形成されていることを特徴とする。【選択図】図５
