PLACING METHOD OF WATERPROOF SHEET
To provide a preferable method for placing a waterproof sheet in a deep internal water surface disposal site.SOLUTION: The method for placing a waterproof sheet in a waste disposal site 1 includes: an excavation groove formation process for forming excavation grooves 30, 31 in an underground before construction of an underground continuous wall (a first wall part 11) and formation of an internal space 7; a side part waterproof sheet attaching process for attaching a side part waterproof sheet 4 to a reinforcing-bar cage 20 so as to cover one side of the reinforcing-bar cage 20; a reinforcing-bar cage insertion process for inserting the reinforcing-bar cage 20 with the side part waterproof sheet 4 attached thereto, into the excavation grooves 30, 31; an underground continuous wall construction process for installing a concrete in the excavation grooves 30, 31 into which the side part waterproof sheet 4 and the reinforcing-bar cage 20 are inserted and for constructing the underground continuous wall; and an internal space formation process for drill-forming the internal space 7 surrounded by the underground continuous wall. In the reinforcing-bar cage insertion process, the reinforcing-bar cage 20 is inserted into the excavation grooves 30, 31 in a manner that the side part waterproof sheet 4 attached to the reinforcing-bar cage 20 is positioned at the inner peripheral surface of the underground continuous wall after the underground continuous wall construction process.SELECTED DRAWING: Figure 6
【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】廃棄物処分場１内に防水シートを敷設する方法は、地中連続壁（第１壁部１１）の構築及び内部空間７の形成に先立って地中に掘削溝３０，３１を形成する掘削溝形成工程と、鉄筋籠２０の一側を覆うように側部防水シート４を鉄筋籠２０に取り付ける側部防水シート取付工程と、側部防水シート４が取り付けられた鉄筋籠２０を掘削溝３０，３１内に挿入する鉄筋籠挿入工程と、側部防水シート４及び鉄筋籠２０が挿入された掘削溝３０，３１内にコンクリートを打設して地中連続壁を構築する地中連続壁構築工程と、地中連続壁によって囲まれる内部空間７を掘削形成する内部空間形成工程とを含む。鉄筋籠挿入工程では、鉄筋籠２０に取り付けられた側部防水シート４が地中連続壁構築工程の後に地中連続壁の内周面に位置するように鉄筋籠２０を掘削溝３０，３１内に挿入する。【選択図】図６
