UNDERWATER JOINT STRUCTURE OF IMPERVIOUS SHEET
To ensure continuity of impermeability and strength of underwater joint parts of impervious sheets laid on surface impermeable work of a waste sea surface disposal site.SOLUTION: It is an underwater joint structure of impervious sheets 20A, 20B of surface impermeable work on the disposal site side of a control type revetment structure constructed to zone the sea surface disposal site, the impervious sheets 21a, 21b to be joined on the base are laid with a predetermined overlap as surface impermeable work, multiple protrusions 23 are arranged on the sheet surface over a predetermined range including the overlapping part of the impervious sheets 21a, 21b, asphalt mastic 25 is filled to include the area where the protrusions 23 are arranged and the continuity of water impermeability and strength of the sheet joint is ensured.SELECTED DRAWING: Figure 1
【課題】 廃棄物海面処分場の表面遮水工に敷設される遮水シートの水中接合部における遮水の連続性、強度の連続性を確保する。【解決手段】 海面処分場を区画するように造成された管理型護岸構造物の処分場域側の表面遮水工の遮水シート２０Ａ，２０Ｂの水中接合構造であって、表面遮水工として基盤上に接合される遮水シート２１ａ，２１ｂが所定の重なりを設けて敷設され、遮水シート２１ａ，２１ｂの重なり部位を含む所定範囲にわたり、シート表面に複数の突起２３が配列され、突起２３が配列された範囲を含むようにアスファルトマスチック２５が充填され、シート接合部位の遮水の連続性と強度の連続性とを確保することを特徴とする。【選択図】 図１
