METHOD FOR PRODUCING WATER SHIELDING EARTH, AND WATER SHIELDING EARTH
PROBLEM TO BE SOLVED: To provide water shielding earth having features such as great earth-tightening strength, a sufficient water shielding effect, hardness to the extent where its surface will not be removed from rainwater and the like, environmental friendliness and easy availability, as a material used in a repair construction due to deterioration, a levee raising construction for increasing the amount of pondage, a maintenance constriction for preventing breakdown of a levee or the like in "ponds", "reservoirs" and the like constructed for agriculture etc.SOLUTION: A method for producing water shielding earth that has plasticity suitable for workability of leveling and rolling compaction, and in which the bond between grains is strengthened by mixing decomposed granite soil with 22 mm or less in grain diameter and particles with 0.075 mm or less in grain diameter obtained from granite ground objects in a predetermined proportion to provide a granularity configuration with high density that can demonstrate a water shielding function. Furthermore, functions of the water shielding earth are improved by utilizing "Tataki" technique, which is a Japanese traditional technique, to mix an appropriate amount of slaked lime.SELECTED DRAWING: Figure 1
【課題】農業用等に造成された「ため池」、「貯水池」などは、老朽化による改修工事、貯水量を増やすための堤体の嵩上げ工事、また提体崩壊を防止するための整備工事等に使用される材料として、土の締め付け強度が大きく、遮水効果が大きく、表面が雨水等で流されないような硬さを持ち、周辺の環境に優しく、簡単に入手できる等の特徴を有する刃金土を提供する。【解決手段】粒径２２ｍｍ以下の真砂土と、花崗岩粉砕物から得られる粒径０．０７５ｍｍ以下の微粒子分を所定の割合で配合し、高密度で遮水性機能を発現できるような粒度構成にすることにより、粒子間の結合を強くし、敷均と転圧の作業性にも適した可塑性を有する刃金土の製造方法。さらに、日本の伝統的技術である「たたき」技術を応用して消石灰を適量混合して機能を高めた刃金土の製造方法。【選択図】図１
