JPS6278308A - Simple installations of dam, fence, and the like - Google Patents

Abstract

PURPOSE:To prevent the falling down of dam, etc., caused by damage by a method in which a high water-absorptive resin and water are charged into a cylindrical flexible film to expand the cylindrical film. CONSTITUTION:A cylinder 4 formed by closing both ends with a flexible film is set on or fixed to a river bed or the ground's surface 13. A mixture 5 of a high water-absorptive resin and water is charged into the cylinder 4, and the cylinder 4 is expanded by the swelling of the water-absorptive resin with water to form a dam or fence. Sand or stone may be further charged into the cylinder 4 as needed.
