To provide a water shielding joint structure of a steel pipe sheet pile, capable of preventing foreign matter contamination in a filler at a time of filling by making a dry state, and capable of securing the quality of a filler for a secondary water shielding layer filler.
A water shielding joint structure 10 of a steel pipe sheet pile shields water by filling, with the filler 16, a pocket 15 constituted of three top and outer joint members 12, 13, 13 for water shielding parts. A primary water shielding layer of the top of steel pipe sheet piles A, B is brought into a perfect water shielding state by bringing the lower end of a top elastic shielding member 18 into contact with a bottom cushioning water shielding member inserted from a groove 12a, turned, and attached. Thereby, The inside of the pocket 15 constituted of three top and outer joint members 12, 13, 13 for water shielding parts of the steel pipe sheet piles A, B is brought into a dry state, and thus the quality of a filler for a secondary water shielding layer can be secured.
