従来、河川決壊時の溢流部にコンクリートブロックや砂
ぶくろを投入して、一時的止水を行っている。Conventionally, concrete blocks and sandbags are put in the overflow area at the time of river collapse to temporarily stop water.
しかしながら、コンクリートブロックは、重量が重く、
しかも多数投入しても、ブロック間には空隙が多くでき
るため、充分な止水効果は上げられない。さらにまた、
このコンクリートブロックは、新たな堤建設時に、これ
らを撤去しなければならない等欠点が多い。However, concrete blocks are heavy,
Moreover, even if a large number of blocks are put in, a sufficient amount of voids can be formed between the blocks, so that a sufficient water blocking effect cannot be obtained. Furthermore,
This concrete block has many drawbacks such as the need to remove these when constructing a new bank.
一方、砂ぶくろは、軽量、単体であるため溢流によって
流失する恐れがあり、完全な止水効果が発揮されない場
合がある。On the other hand, since the sand bag is lightweight and simple substance, it may be washed away by overflow, and the water blocking effect may not be exerted completely.
近来、養浜や海底の浄化で、覆砂による修復工事が多い

浄化の効果を上げ得ないことが多い。In recent years, there are many restoration works by covering sand by purifying beaches and the seabed, but it is difficult to spread evenly heavy sand on top of sludge, and even after succeeding in covering sand, sludge is light, Due to the heavy sand, the sludge and the sand are reversed, and the sand may sink under the sludge, or the surrounding sludge may cover the sand over the sand. Often cannot raise.
また、護岸埋立地での堤防の構築で、土砂が用いられる
が、その腹付は土質によって勾配を付けざるを得ず、こ
の腹付の勾配は、堤防の構築容積を大きくすると欠点が
あり、一方土砂は洗堀さ易く、しかも築堤石間に吸い出
されるという事故が時々発生する。In addition, earth and sand are used in the construction of the embankment at the revetment reclaimed land, but the belly has to be graded depending on the soil quality. On the other hand, the earth and sand are easy to scour, and sometimes accidents occur that they are sucked out between embankments.

接封入では、拡散汚濁物の封じ込めとしては、不安定な
場合があり得るからである。Encapsulation of a substance with a specific gravity of 1 or more in this flexyl bag
In addition to directly encapsulating this in a flexible bag, powder (such as volcanic ash) or something that is easily fluidized (such as dehydrated sludge from sewage and sewage) should be directly enclosed in a large capacity flexible bag. First, a method of packing in small bags and enclosing a large number of these small bags in a large-capacity flexible bag can be used. That is, in the case of powder or a material that is easily fluidized, direct encapsulation is difficult, and in the case of direct encapsulation, the containment of diffusion contaminants may be unstable.

By arranging the bag bodies with the specific gravity of the bag body adjusted to 1 or less on the soft ground surface and fixing them by connecting them to each other, it is possible to quickly build a reinforced road that can be car-passed without being buried in the soft ground. It can be temporarily installed.
When stacking the bag bodies individually without connecting them in a waterproof embankment in the construction of a pond, build the embankment while sandwiching the peripheral part of the waterproof sheet laid on the entire pond between the bag bodies. This makes it possible to form a completely waterproof bank.
