PURPOSE:To form sandbags of constant capacity easily, by filling up the bags of water-permeable material with grains of water-insoluble water-absorbing resin and fibrous substance mixed with each other and formed under pressure. CONSTITUTION:Sandbags 1 are filled up with grains of water-insoluble water- absorbing resin and fibrous substance mixed with each other and formed under pressure in the bags of water-impermeable material, and sandbags 6 are filled u with soil. The sandbags 1 are arranged on the ground 5, and on the bags 1, the sandbags 6 of heavy weight filled up with soil are mounted. By this method, the water-insoluble water-absorbing resin in the sandbags 1 gels absorbing water due to flowing water 8, and so the sandbags of constant capacity can be easily formed, and when the sandbags 1 are combined with the sandbags filled up with soil, then the weight of the whole sandbags is made heavier and can cope with a force applied in the vertical and horizontal directions.
