摘要

PROBLEM TO BE SOLVED: To secure the space in a joint pipe used for connection of an adjacent steel pipe joint and increase the strength of the joint pipe, in election of the steel pipe sheet pile. SOLUTION: A pair of joint pipes 2 formed of circular steel pipes of which the longitudinal slits 2a are formed along the axial direction of the pipes of the steel pipe sheet pile 1 are stuck to the opposite positions on the external side face of the steel pipe sheet pile 1. And further, a spacer plate 10 facing the connection direction of the steel pipe sheet pile 1 is arranged with specified distances in the longitudinal direction of the pipe so as to have a specified protruded length in the inside-outside direction of the joint pipes 2.
