LANDFILL STRUCTURE AND LANDFILL METHOD FOR CONTROLLED FINAL DISPOSAL SITE

PROBLEM TO BE SOLVED: To provide a landfill structure for a controlled final disposal site which can effectively shorten a period from the closure to the abolition of the final disposal site.SOLUTION: In a landfill structure for a controlled final disposal site, organic waste is landfilled in a landfill site where seepage control work is applied, and equipment for collecting and draining seeping leachate is provided on the bottom part thereof. A plurality of unit landfill layers 20 each including a single or a plurality of waste layers 22 and a water sprinkling pipe arrangement layer 23 provided on the top layer of the waste layers 22 are formed upward from the bottom part of the landfill site. In addition, the unit landfill layers 20 are two-dimensionally defined in a plurality of division areas, so that water can be sprinkled on each individual division area via the water sprinkling pipe arrangement layer 23. 【課題】最終処分場の閉鎖から廃止までの期間を効果的に短縮することができる管理型最終処分場の埋立構造を提供する。【解決手段】底部に遮水工と浸出水の集排水設備が設置された埋立地に有機性廃棄物が埋立処理される管理型最終処分場の埋立構造であって、単一または複数の廃棄物層２２と前記廃棄物層２２の最上層に備えた散水管配設層２３とを含む単位埋立層２０が、埋立地の底部から上方に向けて複数層形成されるとともに、前記単位埋立層２０が平面的に複数領域に区画され、前記散水管配設層２３を介して各区画に個別に散水可能に構成されている。【選択図】図２
