Document Type and Number:
WIPO Patent Application WO/2023/152845
Kind Code:
A1
Abstract:
[Problem] A conception of installing a guide wire, for example, was devised and registered under prior art Japanese patent number 6118953 so as to enable full opening of a folding-screen type folding portion of a multistage tsunami buffer weir registered under prior art Japanese patent number 5207091. However, since the conception requires auxiliary equipment such as a guide wire and devices, the present invention involves making an improvement to eliminate such requirements. [Solution] When a multistage breakwater vertical door is folded like a folding screen and stored, breakwater vertical door pieces moving in a direction reverse of the travelling direction of tsunami are present every two stages, and it is necessary to assist the movement. Accordingly, the present invention has overcome the problem by folding, in a manner as to roll, the multistage breakwater vertical door so that all stages thereof move in the same direction as the travelling direction of tsunami, disposing structural bodies having the same width as the breakwater vertical door in gaps at joining portions generated due to the thickness of the stages of the breakwater vertical door, and closing the gaps. Further, the present invention improves surface integral tsunami disaster reducing performance of the structural bodies.
