IMPERVIOUS LAYER CONSTRUCTION METHOD
To provide an impervious layer construction method that can prevent water leakage without smoothing a slope of a soil structure.SOLUTION: The impervious layer construction method includes the steps of: installing a formwork 10 on a slope Ta of a dam body T, filling bentonite mixed soil 2 in the installed formwork 10, and scattering out a soil cover 3 to the outside of the installed formwork 10; and pulling out the formwork 10, and rolling and compacting the bentonite mixed soil 2 and the soil cover 3. By repeating these steps, the bentonite mixed soil 2 is constructed stepwise with respect to the slope Ta of the dam body T.SELECTED DRAWING: Figure 2
【課題】土構造物の斜面を平滑にせずとも、漏水を防止することができる遮水層構築工法を提供する。【解決手段】堤体Ｔの斜面Ｔａに対して型枠１０を設置し、その設置した型枠１０内にベントナイト混合土２を充填すると共に、その設置した型枠１０の外側に覆土３を撒き出し、その後、型枠１０を引き抜き、ベントナイト混合土２と覆土３を転圧するという工程を繰り返し行うことにより、堤体Ｔの斜面Ｔａに対してベントナイト混合土２を段状に構築してなる。【選択図】図２
