SAND GRAVEL SOLIDIFICATION BODY FORMATION METHOD AND LAND AREA PRESERVATION METHOD
PROBLEM TO BE SOLVED: To provide land area preservation means for reducing labor, reducing cost, and also reducing influence on a natural environment.SOLUTION: A sand gravel solidification body formation method is provided for supplying an organic acid to a half-closed area in the shoreline vicinity of substantially isolating seawater from the ocean when a water level lowers and also holding calcium including sand gravel. An organic component or an organic component including material is made to exist in the half-closed area in the shoreline vicinity, and the organic acid is supplied to its area, so that a beach-rock-like sand gravel solidification body can be formed in a shorter period than in the natural environment. Thus, a sand gravel solidification body can be formed at low cost in low labor in a shoreline vicinity area, and a land area can be preserved at low cost in low labor. Even if the sand gravel solidification body is formed, it has no influence on the natural environment in the principle. This sand gravel solidification reaction can be largely promoted by supplying calcium including crushed chips having an average particle diameter of 1 mm or less to the half-closed area in the shoreline vicinity.
【課題】低労力、低コストかつ自然環境への影響の少ない陸域保全手段の提供。【解決手段】水位低下時に海水が海洋から略隔離され、かつカルシウム含有砂礫が保持された汀線近傍の半閉鎖領域に、有機酸を供給する砂礫固化体形成方法を提供する。汀線近傍の半閉鎖領域に有機成分又は有機成分含有物を存在させ、その領域に有機酸を供給することで、自然環境におけるよりも短期間にビーチロック様の砂礫固化体を形成できる。従って、汀線近傍域などに砂礫固化体を、低労力かつ低コストに形成することが可能であり、低労力かつ低コストに陸域を保全できる。また、砂礫固化体を形成しても、原則的に、自然環境に影響しない。この砂礫固化反応は、汀線近傍の半閉鎖領域に平均粒径1mm以下のカルシウム含有砕屑粒子を供給することにより、大幅に促進できる。【選択図】なし
