In addition, 7 in the figure is a support frame in the shape of a right triangle, which supports both the upper and lower ends of the pile driving insertion tube 5 attached to the rising weir part 2 of the defense sheet 1 from the side opposite to the water side W. , its bottom portion 7a is fixed to the ground G by driving short iron stakes 8. Furthermore, 9 in the figure is a wire that maintains the upper end of the rising weir section 2 of the defense sheet stretched along the longitudinal direction. Furthermore, reference numeral 10 in the figure indicates a pile insertion hole formed in the vicinity of the boundary on the rising weir section 2 side of the sandbag stacking surface 3 of the defense sheet 1, and as shown in another embodiment in FIG. When unfolding the sandbag stacking surface part 3 by bending it to the side opposite to the water side W,
Each of the insertion steel pipes 5 for pile driving and the long iron piles 6 can be easily inserted.

As shown in FIG. 6A, when the above-mentioned defense sheet 1 is stored, the upright weir section 2 including the pile driving insertion tube 5 and the sandbag stacking surface section 3 are folded in half and rolled up. In addition, other long iron piles 6, short iron piles 8, nails 4, etc. are now stored individually as shown in Figure 6 B, C, D, and E. ing.

Furthermore, the support frame 7 is shown in FIGS. 7A and 7B.
As shown in FIG. 8, gripping portions 71 and 72 for gripping both the upper and lower ends of the pile driving insertion tube 5 may be provided vertically independently, or as shown in FIG. 8A and B, gripping portions 71 and 72 may be provided vertically and continuously. A gripping portion 73 is provided, and furthermore,
As shown in FIGS. 9A and 9B, the support frame 7 is made freely foldable, and the gripping part 74 and the grounding part 75 shown in FIG. 9B are screwed together to expand and contract from the folded storage state shown in FIG. 9A. Adjustable support leg 7
6 and 77 respectively, and by extending the distal end portion 77 of the supporting leg portion and locking it to the rear end side of the grounding portion 75 via a pin 78, it is possible to assemble it.

That is, in order to carry out defense work in the event of a flood using the disaster prevention tool having the above-mentioned configuration, as shown in FIGS. 1 at the disaster site, and insert pipe 5 for pile driving in the rising weir section 2.
First, while inserting a long iron pile 6 and driving the pile with a hammer H, the rising weir part 2 of the defense sheet 1 is fixed on the ground G in an upright state (see Fig. 10).
Four nails are driven into the periphery of the sandbag stacking surface 3 of the defense sheet 1 using a hammer H to fix it on the ground G in a laid state so that both form an L-shape (see FIG. 11). Next, the rising dam part 2 of the defense sheet 1
A support frame 7 is applied to both the upper and lower ends of each of the pile driving insertion pipes 5 from the opposite side to the water side W of After piling G with a hammer H (see Fig. 12), the sandbags 11 can be loaded onto the sandbag stacking surface 3 laid on the water side W (see Fig. 13). ).

By the way, in order to attach the above-mentioned pile driving insertion tube 5 to the upright weir part 2 of the defense sheet 1, in addition to the pocket stowed state shown in FIGS. As shown in A and B, it is also possible to configure so that the upper end of the pile driving insertion tube 5 is movably held by a wire 9.
