LIFT PRESSURE REDUCTION DEVICE, LIFT PRESSURE REDUCTION STRUCTURE, AND INSTALLATION METHOD OF LIFT PRESSURE REDUCTION DEVICE
PROBLEM TO BE SOLVED: To provide a lift pressure reduction device capable of reducing a lift pressure given by a tsunami etc. with a simple structure.SOLUTION: The lift pressure reduction device is a device used for structures which have a space allowing water to enter. The lift pressure reduction device includes: a bag body filled with gas 2; and a hanging part 3 for attaching a bag body to the structure. The bag body has a bottom face 2a in which at least a communication port is formed for communicating the outside and the inside of the bag body, and a hanging ring constituting a hanging part of the bag body is preferably provided to an upper plane 2b. The lift pressure reduce structure is configured by a plurality of bag bodies which are attached to the bottom face 12a of a waterway top 12 facing the entering water top W.SELECTED DRAWING: Figure 1
【課題】津波等から受ける揚圧力を簡単な構成で低減することが可能な揚圧力低減装置を提供する。【解決手段】水が浸入する空間を有する構造物用の揚圧力低減装置である。そして、気体が充満された袋体部２と、袋体部を構造物に取り付けるためのつり下げ部３と、を備えている。ここで、袋体部には、袋体部の内外に連通する連通口が少なくとも下面２ａに設けられており、袋体部の上面２ｂにはつり下げ部を構成するつり輪が設けられていることが好ましい。また、揚圧力低減構造は、複数の袋体部が、浸入する水面Ｗに対向する水路天端１２の下面１２ａに取り付けられることによって構成される。【選択図】図１
