To provide a sandbag which is light in weight and easy in installation work, resits being flowed by water and blown off by wind, when it is difficult to be prepared in advance at the time of disaster due to a sudden change in state.SOLUTION: A sandbag is composed of an outer bag 1 formed into a square cube of a linen material having water permeability, and an inner bag 2 and an iron sand bag 4 stored in the outer bag 1, in which the iron sand bag 4 is provided at the bottom of the outer bag 1 in which two sites of a side part of an upper cloth and an upper part of a side cloth of the outer bag 1 formed into the square cube are sewn and further two sites of a side part of a lower cloth and a lower part of the side cloth are sewn to form two openings, gusset parts 9 are provided on the two sides, two magictapes (R) 5 are attachably/detachably provided one by one in the two side parts, and an ultra-water absorbing resin 3 is collected in the middle of the inner bag 2.SELECTED DRAWING: Figure 3
【課題】急な状況の変化による災害時に、前もって準備をすることが困難な場合、軽量で設置作業が簡単で、なおかつ水に流されず、風にも飛ばされない土嚢が求められている。【解決手段】通水性を備える麻材で四角立方体に形成した外袋１と、外袋１内に収納される内袋２と砂鉄袋４とからなる土嚢において、前記四角立方体に形成する外袋１の上布の側部と側布上部の２ヵ所で縫製し、さらに下布の側部と側布下部の２ヵ所で縫製して開口部を２ヵ所形成した外袋の底には砂鉄袋４を２側辺はガゼット部９を設け、２側辺部に１個ずつ、２ヵ所マジック（登録商標）テープ５で着脱自在に設け、前記内袋２には、超吸水性樹脂３を中程に集まるように挿入した土嚢【選択図】図３
