場合が生じることがある。FIG. 1 shows a steel sheet pile la (1) and a steel sheet pile lb.
(1) shows a plane in a state when it is embedded in the ground. The steel sheet pile 1 is provided to prevent collapse of the surrounding ground and outflow of groundwater when excavating the ground. When the steel sheet pile 1 is driven, there may be a case where the groove 2a of the steel sheet pile la and the groove 2b of the steel sheet pile 1b do not mesh with each other.

この結果、持ち運びが容易となる。The water blocking plate 4 has a band-like shape in which the grooves 5a and 5b are provided symmetrically. This is a shape which does not come off from the grooves 2a, 2b of the steel sheet piles 1a, lb, and has some allowance as shown by a broken line portion 6 in FIGS. 2 (a), 2 (b). The water stop plate 4 is formed of flexible polyvinyl chloride (PCV) or chloroprene rubber or the like, and is freely deformed to fit in the gap 3 between the non-meshing steel sheet piles 1a and 1b. It is fitted and closed. In this way, since the gap 3 is closed, soil and groundwater do not flow out during the excavation work of the ground. Further, since the water stop plate 4 is flexible, as shown in FIG. 2 (e), it can be deformed into a roll shape.
As a result, carrying becomes easy.
