IMPERVIOUS STRUCTURE AND IMPERVIOUS METHOD UNDER VEHICLE ENTRY PASSAGE IN WASTE FINAL DISPOSAL SITE
PROBLEM TO BE SOLVED: To prevent a slip between multi-layer laminate members and between slopes without impairing imperviousness to water in an impervious structure under a vehicle entry passage even if a vehicle loaded with waste runs on the vehicle entry passage.SOLUTION: An impervious structure 100 under a vehicle entry passage 104 in a waste final disposal site includes: a lower protective layer 111 laid on a slope 101; a first stationary plate 120 having an anchor 122 driven in the slope 101 through the lower protective layer 111; a lower layer impervious sheet 112 laid on the lower protective layer 111 that is fusion-bonded to a fusion-bonding part 121 of the first stationary plate 120; an intermediate protective layer 113 laid on the lower layer impervious sheet 112; an upper layer impervious sheet 114 laid on the intermediate protective layer; a second stationary plate 130 disposed in a through-hole 133 of the intermediate protective layer 113 that is fusion-bonded to the lower layer impervious sheet 112 at a fusion-bonding part 132, and fusion-bonded to the upper layer impervious sheet 114 at a fusion-bonding part 131; and an upper protective layer 115 laid on the upper layer impervious sheet 114.
【課題】廃棄物を積載した車両が車両進入路を走行しても、車両進入路下の遮水構造において、遮水性を損なうことなく、多層積層部材間及び斜面間の滑りを防止する。【解決手段】廃棄物最終処分場内の車両進入路１０４下の遮水構造１００は、斜面１０１上に敷設された下層保護層１１１と、下層保護層１１１を介して斜面１０１に打ち込んだアンカー１２２を有する第１固定板１２０と、下層保護層１１１の上に敷設されて第１固定板１２０の融着部１２１と融着固定された下層遮水シート１１２と、下層遮水シート１１２の上に敷設された中間保護層１１３と、中間保護層の上に敷設された上層遮水シート１１４と、中間保護層１１３の貫通穴１３３に配置されて下層遮水シート１１２と融着部１３２とで融着されると共に上層遮水シート１１４と融着部１３１と融着された第２固定板１３０と、上層遮水シート１１４の上に敷設された上層保護層１１５とから構成される。【選択図】図１
