JOINT STRUCTURE OF STEEL PIPE SHEET PILE
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.
【課題】 先行して打設する鋼管矢板の継手（Ｐ型継手）の内部に土砂が侵入することを防止し、さらに、先行して打設する鋼管矢板の継手（Ｐ型継手）の内部に、後行して打設する鋼管矢板の継手（Ｔ型継手）を容易に挿入可能とする。【解決手段】 Ｔ型継手２０に防水部材３０を取り付け、Ｐ型継手４０の内部にＴ型継手２０を挿入して、隣合う鋼管矢板１０同士を接続する。Ｔ型継手２０は、その下端部から延長して設けた突出部２１を有し、Ｐ型継手４０は、長さ方向に連続したスリット状の開口部４１を有する。当該開口部４１は、閉塞部材４２により閉塞する。閉塞部材４２は、開口部４１の長さ方向に沿って脆弱部４３を有する。先行鋼管矢板１０に隣接させて後行鋼管矢板１０を打設する際に、Ｐ型継手４０に設けた閉塞部材４２の脆弱部４３を突出部２１で切り裂きながら、Ｐ型継手４０の内部にＴ型継手２０を挿入する。【選択図】図４
