体(4)の中に高吸水性樹脂と水の両者(5)を入れて
高吸水性樹脂の吸水による膨潤により該筒状体を膨満せ
しめ自立的形状を成さしめて、堰或いは障壁物等とする
ことを特徴とする(図(b)参照)。(Means for Solving the Problems) That is, the present invention, as shown in FIG. Both the superabsorbent resin and water (5) are placed in the body (4), and the superabsorbent resin swells due to water absorption, causing the cylindrical body to swell into a self-supporting shape to form a weir, barrier, etc. (See figure (b)).
上記に於いて、筒状体の中の充填は高吸水性樹脂単独と
水でもよいし、単独の高吸水性樹脂に代え高吸水性樹脂
をゴムないしプラスチックと混合したものとしたもので
もよい。ゴムないしプラスチックと混合するのは適度な
強度と膨潤度を付与するためである。In the above, the cylindrical body may be filled with a super absorbent resin alone and water, or a super absorbent resin mixed with rubber or plastic may be used instead of the super absorbent resin alone. The purpose of mixing with rubber or plastic is to impart appropriate strength and swelling degree.
さらに、該充填物に適度な重量増と該高吸水性樹脂体積
分率の低下を図るため、第2図のように砂や石(6)を
混ぜこんでおいてもよい。Furthermore, in order to increase the weight appropriately and reduce the volume fraction of the superabsorbent resin, sand or stones (6) may be mixed into the filling as shown in FIG.

)と進む、なお(9)は水である。Preferably a zipper (8) that can be opened and closed as shown in FIG.
is provided on the cylindrical body, and after construction, that is, after fixing the cylindrical body,
It is best to put the filling through the opening, close the zipper, pour some water through the zipper, and leave it to inflate. Figure 6 shows the procedure. The construction procedure in Figure 6 is (from al (bl), (bl from ((1), flJ [d
), and (9) is water.
このファスナー付きの場合施工が容易であるとともに、
不要で撤去となったとき、ファスナーを開けて充填物を
とり出せば、該筒状体は再使用も可能である。This type of zipper is easy to install, and
When the cylindrical body is no longer needed and needs to be removed, the cylindrical body can be reused by opening the zipper and taking out the filling.

(発明の効果)
以上の様な本発明の堰、障壁物等設置物によると次の様
な効果がある。(Effects of the Invention) The installed structures such as weirs and barriers of the present invention as described above have the following effects.
■傷がついても倒れたりしない。■Does not fall down even if injured.
第7図のような中空体を水や空気で膨満させたものは、

ばさほど重要でない。A hollow body inflated with water or air as shown in Figure 7 is
If the membrane material is penetrated and scratched, water and air will not be able to escape and it will not be able to maintain its shape. However, in the product of the present invention, the filling is a self-supporting lump, so even if the membrane material is slightly scratched, it will not lose its shape, and airtightness and watertightness are not important once it is inflated. 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。Since the filling can be filled even after installation, the cylindrical body can be folded or rolled up to reduce its volume, and is lightweight and transportable, making it easy to work with.
■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。As mentioned above, strict airtightness and watertightness are not required. Moreover, if the cylindrical body is provided with a fastener as shown in FIG. 5, it can be easily removed as long as the filling is taken out.
■コストが安い。■Low cost.
水で膨潤させ、体積を増やすので材料費も安い。■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。The material cost is also low because it swells with water and increases its volume. ■Construction costs and removal costs are also low. Furthermore, even after removal, the cylindrical body can be reused.
