WATER-SHIELDING STRUCTURE OF SEA SURFACE DISPOSAL FIELD REVETMENT
To secure water-shielding properties of a sheet end in a base part, a dividing part and a structure fixing part of a water-shielding sheet of a vertical water-shielding structure of a control type revetment for a sea surface disposal field.SOLUTION: In a base part water-shielding layer in a vertical water-shielding work constructed so as to partition a sea surface disposal field revetment, a dividing part of a water-shielding sheet, and a fixing part of a caisson 4, a lower end of an intermediate water-shielding sheet 21 is welded and joined to the upper surface of the water-shielding sheet 20 so as to be brought into contact with and held to a foot protection water-shielding layer 30, a penetration passage length of the surface of the foot protection water-shielding layer 30 and the water-shielding sheet 20 is extended, a space including the end of the water-shielding sheet 20 and the branched water-shielding sheet in a sheet division part and a part fixed to the surface of the caisson 4 are divided by a steel sheet pile and a cover member, and a water-shielding block is formed which is obtained by filling the space with asphalt mastic and cooling and solidifying the same.SELECTED DRAWING: Figure 1
【課題】 海面処分場のための管理型護岸の鉛直遮水構造の遮水シートの基部、分断部、構造物定着部におけるシート端部の遮水性を確保する。【解決手段】 海面処分場護岸を区画するように造成された鉛直遮水工の基部遮水層、遮水シートの分断部、ケーソン４への定着部において、遮水シート２０の上面に、根固め遮水層３０に密着して保持されるように中間遮水シート２１の下端を溶着接合させ、根固め遮水層３０表面と遮水シート２０との浸透路長を延長し、またシート分断部位、ケーソン４表面に定着される部位での遮水シート２０端部と分岐遮水シートとを含む空間を、鋼製矢板とカバー部材で区画して、その空間にアスファルトマスチックを充填冷固させた遮水ブロックを形成する。【選択図】 図１
