PROBLEM TO BE SOLVED: To provide a sandbag swelling more rapidly and uniformly.SOLUTION: In a sandbag 1, a water absorbing body 3 having a water-absorbing resin 32 held between two water-permeable or hydrolytic sheets 31 is encapsulated in an outer bag 2. A plurality of joints joined to one another with bonding power and separated from one another by swelling of the water-absorbing resin 32 are formed in the two sheets 31. The water-absorbing resin 32 is held in the state of being subdivided into a plurality of block spaces enclosed with the joints and the two sheets 31.
【課題】より素早く均一に膨潤する土嚢を提供する。【解決手段】土嚢１は、外袋２に、透水性又は水解性の２枚のシート３１の間に吸水性樹脂３２が保持された吸水体３が封入されて構成されている。２枚のシート３１には、吸水性樹脂３２の膨潤により剥がれる接合力で互いに接合された複数の接合部が形成されており、吸水性樹脂３２は、前記接合部と２枚のシート３１とに囲まれた複数ブロックの空間に小分けにされて保持されている。【選択図】図２
