IMPERMEABLE STRUCTURE OF SLOPE AND ITS CONSTRUCTION METHOD
To provide an impermeable structure of a slope with high impermeable performance as well as being able to be constructed using only relatively inexpensive materials.SOLUTION: Provided is an impermeable structure of a slope provided as an impermeable layer 1 which is a surface layer of the slope. Then, a slag material, which is a mixture of steel slag and blast furnace water-granulated slag, is compacted so that the compaction density ratio is 90% or more. Here, it is preferable to compact the slag material so that the compaction density ratio is 95% or more. Further, it is preferable that the thickness of the impermeable layer formed by the slag material is 100 mm to 200 mm, and the hydraulic conductivity of the impermeable layer formed by the slag material is 3.0×10-6 m/s or less.SELECTED DRAWING: Figure 2
【課題】比較的安価な材料のみで構築できるうえに、遮水性能の高い斜面の遮水構造を提供する。【解決手段】斜面の表層となる遮水層１として設けられる斜面の遮水構造である。そして、製鋼スラグと高炉水砕スラグとを混合したスラグ材を、締固め密度比が90％以上となるように締め固めたことによって構築される。ここで、前記スラグ材の締固め密度比が95％以上となるように締め固めることが好ましい。また、スラグ材によって形成される遮水層の厚さを100mm−200mmとし、スラグ材によって形成される遮水層の透水係数が3.0×10-6m/s以下となるようにすることが好ましい。【選択図】図２
