WATER SHIELDING STRUCTURE OF WATER SHIELDING SHEET END PART AND CONSTRUCTION METHOD OF THE SAME
To provide a water shielding structure of a water shielding sheet, which achieves stable holding of a sheet end part at a connection portion of the water shielding sheet of a vertical water shielding structure of a controlled revetment for a sea surface disposal station, and ensures water shielding properties after completion.SOLUTION: A pivot 32 is provided near a lower end of a steel sheet pile 6 at a parting construction position in a part where a water shielding sheet 20, which is laid along the outer side surface of the steel sheet pile 6, is parted and constructed, and a lower end of a wall body 30 which fixes the end part of the water shielding sheet 20 at a position of the pivot 32 is positioned and held. A closed space 7 is formed by the wall body 30 and the steel sheet pile 6. Across a position where the water shielding sheet 20 is parted, each sheet end part of the water shielding sheet 20 placed at the steel sheet pile 6 consecutively constructed is fixedly held by the wall body 30, and asphalt mastic A (7) is charged into the closed space 7.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接続部位におけるシート端部の安定した保持、完成後の遮水性の確保を果たす。【解決手段】 鋼製矢板６の外側側面に沿って敷設される遮水シート２０が分断施工される部位において、分断施工位置での鋼製矢板６の下端近傍にピボット３２を設け、ピボット３２位置で遮水シート２０の端部を定着する壁体３０の下端が位置決め保持される。壁体３０と鋼製矢板６とで閉空間７が形成され、遮水シート２０が分断された位置を挟んで、連続して施工された鋼製矢板６に敷設された遮水シート２０の各シート端部が壁体３０によって定着保持され、閉空間７内にアスファルトマスチックＡ（７）が充填された構造からなる。【選択図】 図１
