ばさほど重要でない。A hollow body as shown in Fig. 7 which is inflated with water or air,
If the membrane material is penetrated by scratches, water and air will escape and the shape cannot be maintained. However, since the filling material of the present invention is a lump that forms a self-supporting shape, it does not lose its shape even with respect to the membrane material that is covered by a few scratches, and airtightness and watertightness are important once they are fully expanded. Not.
工法が容易である。The construction method is easy.
設置後でも充填物を入れられるので、該筒状体は折りた
たんだり、巻いたりして体積を小さくして、また軽量で
運搬でき、作業もしやすい。上記にのべたことから厳
密な気密性、水密性も要求しない。また第５図のような
ファスナーを設けた筒状体であれば、撤去のとき、充填
物さえ出せば撤去も容易である。Since the filler can be put in even after the installation, the tubular body can be folded or rolled to reduce its volume, can be transported with a light weight, and is easy to work. Because of the above, strict air tightness and water tightness are not required. Further, in the case of a tubular body provided with a fastener as shown in FIG. 5, it is easy to remove if the filling material is taken out at the time of removal.
コストが安い。The cost is low.
水で膨潤させ、体積を増やすので材料費も安い。上記
から工事費や撤去費も安い。また撤去後も、筒状体の再
使用は可能である。Material cost is low because it swells with water and increases the volume. From the above, construction costs and removal costs are also low. Moreover, the tubular body can be reused after the removal.
