<p>PROBLEM TO BE SOLVED: To prevent the intrusion of sediment into a joint (P-type joint) of a steel pipe sheet pile which is antecedently driven, and to easily insert a joint (T-type joint) of the steel pipe sheet pile which is succeedingly driven into the joint (P-type joint) of the steel pipe sheet pile which is antecedently driven.SOLUTION: A waterproof member 30 is attached to a T-type joint 20, the T-type joint 20 is inserted into a P-type joint 40, and adjacent steel pipe sheet piles 10 are connected to each other. The T-type joint 20 has a protrusion 21 which is arranged while extending from a lower end of the T-type joint, and the P-type joint 40 has a slit-shaped opening part 41 which is continued to a longitudinal direction. The opening part 41 is blocked by a block member 42. The block member 42 has a fragile part 43 in the longitudinal direction of the opening part 41. When driving the succeeding steel pipe sheet pile 10 by making it adjoin the antecedent steel pipe sheet pile 10, the T-type joint 20 is inserted into the P-type joint 40 while cutting the fragile part 43 of the block member 42 arranged at the P-type joint 40 by the protrusion 21.</p> |
