OPENING PORTION WATERPROOF STRUCTURE, AND WATER INSULATION SHEET
To provide an opening portion waterproof structure and a water insulation sheet capable of further improving reliability of a waterproof performance in an opening portion provided at an upper side of a pit.SOLUTION: An opening portion waterproof structure 1 comprises: a water insulation sheet 10 which has a bag shape, which is attached to inner peripheral faces 100a, 100b of an opening portion 100 provided at an upper side of a pit in a state where the bag shape is downwardly opened, which has a peripheral wall 11 along the inner peripheral face at least at a lower part of the water insulation sheet 10, and which has a watertight zipper 13 that opens/closes an upper part of the water insulation sheet 10, forms an entrance of a worker or a work machine in an open state, and prevents water from immersing in a closed state; and a seal structure 20 sealing between the inner peripheral faces 100a, 100b and the peripheral wall 11. The water insulation sheet 10 can deform between a stored state of being stored below a lid 200 of the opening portion 100 and an elongated state where the lid 200 is removed and an upper end of the water insulation sheet 10 is positioned substantially at the same position as the ground surface G or above the ground surface G.SELECTED DRAWING: Figure 1
【課題】ピット上側に設けられた開口部における防水性能の信頼性をより高めることが可能な開口部の防水構造および遮水シートを提供する。【解決手段】開口部の防水構造１は、袋形状を有し、当該袋形状が下方に向けて開放された状態でピット上側に設けられた開口部１００の内周面１００ａ、１００ｂに取り付けられた遮水シート１０であって、遮水シート１０の少なくとも下部において内周面に沿う周壁１１と、遮水シート１０の上部を開閉可能とし開状態では作業員または作業機械の出入口を形成し閉状態では水の浸入を防ぐ水密ファスナ１３と、を有し、内周面１００ａ、１００ｂと周壁１１との間をシールするシール構造２０と、を備える。遮水シート１０は、開口部１００の蓋２００の下方に収納された収納状態と、蓋２００が取り外され遮水シート１０の上端が地表面Ｇと略同じ位置かあるいは地表面Ｇよりも上方に位置する伸長状態との間で変形可能である。【選択図】図１
