METHOD OF LAYING WATERPROOF SHEET
To provide a suitable technique for laying a waterproof sheet in a deep-type inner water surface disposal field.SOLUTION: A method of laying a waterproof sheet (a side waterproof sheet 4 and a bottom waterproof sheet 5) is a method for laying the waterproof sheet in a waste disposal field 1 having a tubular wall body 2 which has an inner space 7 into which waste is disposed and extends in a vertical direction in underground, and a bottom part (an excavation bottom surface 8) which blocks up a lower opening of the wall body 2. The method of laying the waterproof sheet includes: a first step of manufacturing a tubular first waterproof sheet (a first-stage side waterproof sheet 20) having an outer peripheral surface that can face an inner peripheral surface of the wall body 2; a second step of joining a lower end of a second waterproof sheet (a second-stage side waterproof sheet 20) at an upper end of the first waterproof sheet with the first waterproof sheet positioned in the wall body 2 in plan view; and a third step of descending the joined first waterproof sheet and second waterproof sheet along the inner peripheral surface of the wall body 2.SELECTED DRAWING: Figure 4
【課題】深型・内水面処分場内に防水シートを敷設するための好適な手法を提供する。【解決手段】防水シート（側部防水シート４及び底部防水シート５）の敷設方法は、廃棄物が投棄される内部空間７を有して地中を鉛直方向に延びる筒状の壁体２と、壁体２の下側開口部を塞ぐ底部（掘削底面８）とを有する廃棄物処分場１内に防水シートを敷設する方法である。防水シートの敷設方法は、壁体２の内周面に外周面が相対可能な筒状の第１防水シート（１段目の側部防水シート２０）を製作する第１の工程と、平面視で壁体２内に第１防水シートを位置させた状態で、第１防水シートの上端部に第２防水シート（２段目の側部防水シート２０）の下端部を接合する第２の工程と、接合された第１防水シート及び第２防水シートを壁体２の内周面に沿って下降させる第３の工程と、を含む。【選択図】図４
