ROLL TYPE MULTISTAGE TSUNAMI BUFFER WEIR
To improve a multistage tsunami buffer weir registered in the previous patent No. 5207091 by devising and registering a device such as installing guide wires in the previous patent No. 6118953 so that all folding parts of a folding screen style of the multistage tsunami buffer weir can be opened, but this device requires auxiliary equipment and devices such as guide wires, etc., so that they are omitted.SOLUTION: When multistage breakwater doors are folded and stored in the form of a folding screen, there is a breakwater door that moves in the direction opposite to the traveling direction of the tsunami every other step, and it is necessary to assist the operation. Therefore, all stages of the multistage breakwater doors are rolled and folded so that they move in the same direction as the tsunami's progress. By arranging a structure with the same width and length as the breakwater door in a gap between joints caused by the thickness of the breakwater door on each stage, the gap is closed and the problem is solved. Furthermore, the tsunami disaster mitigation performance is improved by the area of the structure.SELECTED DRAWING: Figure 1
【課題】前特許第５２０７０９１号で登録した多段津波緩衝堰の屏風形式の折り畳み部分が全て開くように、前特許第６１１８９５３号でガイドワイヤを設置するなどの工夫を考案して特許登録したが、この考案では、ガイドワイヤなどの付帯設備や工夫が必要となることから、それらを省くように改善すること、【解決手段】多段防波立扉を屏風形式で折り畳んで収納した場合、津波の進行方向と逆向きに移動する防波立扉が一段置きに存在し、その動作を補助する必要がある。そこで、多段防波立扉の全ての段が津波の進行方向と同じ向きに移動するようにロール式に巻いて折り畳むこととし、各段の防波立扉の厚みのために生じる接合部分の隙間に防波立扉と同じ幅長さの構造体を配置することにより隙間を塞ぎ問題点を解消した。そして、更にはその構造体の面積分津波減災性能を向上させることとした。【選択図】図１
