OVERLAYING SAND METHOD
PROBLEM TO BE SOLVED: To provide an overlaying sand method capable of preventing turbidity from occurring because microscopic particles 6 included in an overlaying sand material are diffused in water, and capable of preventing a bottom mud layer 2 from being formed on an overlaying sand material layer 11 because the overlaying sand material disturbs the bottom mud layer 2 to make bottom mud rise and precipitate, during execution of overlaying sand work.SOLUTION: An overlaying sand method of the present invention is characterized in that an overlaying sand material plate 8 formed by hardening zeolite particles by a biodegradable binding material is sunk to the bottom of water.
【課題】 覆砂の施工時に、覆砂材に含まれる微細な粒子６が水中に拡散して、濁りが生じることを防止するとともに、覆砂材が底泥層２を乱して、底泥が舞い上がり、沈降して、覆砂材層１１の上に底泥層２が形成されることを防止することができる覆砂工法を提供する。【解決手段】 本発明の覆砂工法は、ゼオライト粒子を、生分解性結合材によって固めることによって形成した覆砂材プレート８を水底に沈めることを特徴とするものである。【選択図】 図２
