CONSTRUCTION METHOD OF WATER SHIELD SHEET AND WATER SHIELD LINER
To provide a construction method of a water shield liner using a water shield sheet and reduction in an amount of use of a water shield material of the water shield liner.SOLUTION: In a construction method of a water shield liner, a contact surface of a water shield sheet 26B of a lower layer and a deformation conformity water shield material 30 is maintained on a surface parallel to a contact surface (bottom surface) 14 of a water shield sheet 22, a contact surface of a water shield sheet 26A of an upper layer and the deformation conformity water shield material 30 is maintained at a surface parallel to a side surface of a weight member 28 standing toward a ground contact surface of the water shield sheet 22, a predetermined thickness covering the deformation conformity water shield material 30 is made to be a predetermined width X1 folding up at least the water shield sheet 26A of the upper layer, and a contact surface area of the water shield sheet 26A of the upper layer and the water shield layer 26B of the lower layer is maintained at a degree same as the deformation conformity water shield material 30, hence a distance between a vertical water shield wall 16 and a weight member 28 can be set shorter as the predetermined width X1 folding up the water shield sheet 26A of the upper layer, thereby reducing the necessary volume of the deformation conformity water shield material 30.SELECTED DRAWING: Figure 1
【課題】遮水シートを用いた遮水工の施工方法及び遮水工の遮水材使用量の低減。【解決手段】下層の遮水シート２６Ｂと変形追随性遮水材３０との接触面は、遮水シート２２の接地面（底面）１４と平行な面上で確保し、上層の遮水シート２６Ａと変形追随性遮水材３０との接触面は、遮水シート２２の接地面に対して立ち上がるウエイト部材２８の側面と平行な面で確保し、変形追随性遮水材３０を被覆する所定の厚みを少なくとも上層の遮水シート２６Ａを折り上げた所定幅Ｘ１とすることで、上層の遮水層２６Ａ、下層の遮水層２６Ｂと変形追随性遮水材３０との両者の接触面積を同等程度確保することで、上層の遮水シート２６Ａを折り上げた所定幅Ｘ１の分だけ、鉛直遮水壁１６とウエイト部材２８との距離を短く設定でき変形追随性遮水材３０の必要体積の低減を図る遮水工の施工方法。【選択図】図１
