PILE CONNECTION STRUCTURE OF PILE, AND PILE AND BLADE CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a pile connection structure which facilitates connection of piles together.;SOLUTION: There is provided a pile connection structure for connecting ends 2 of the two cylindrical piles 1 together by a short cylindrical joint 3. According to the structure, the pile 1 has a plurality of radially projecting bumps 6 formed on the end 2 thereof, and has arched portions and projections alternately arranged on an end face thereof. Further the joint 3 has an inner flange 10 at an intermediate portion thereof in an axial J direction. The inner flange 10 has formed therein an annular groove 13 consisting of arched grooves 11 and projective grooves 12 corresponding to the arched portions and the bumps, respectively. Then the bumps 6 are guided via a guide groove formed in an internal peripheral surface of the joint 3 to be inserted into the projective grooves 12, and thus the piles are connected to each other.;COPYRIGHT: (C)2008,JPO&INPIT
