Reclamation facility

Abstract

PROBLEM TO BE SOLVED: To provide a reclamation facility being easy to construct and capable of retaining a barrier function over a long period from the beginning and having an origin for escape of gas. SOLUTION: The reclamation facility 11 is constructed in the foundation involving ground water and is for reclaiming waste 12 in its inside. The facility is composed of an only slightly water-permeable water-shielding layer 14, and two or more porous members 21 are arranged on the inside surface of the water-shielding layer 14. Since the porous members ensure progression of a pulsating invasion phenomenon of the gas area into the water-shielding layer, gas permeates through the only slightly water-permeable water-shielding layer 14 under lower pressure.

【課題】施工が容易でバリア機能を当初から長期に亙って維持できると共に、ガスの逃げ道の起点を備えた埋設処分施設を提供する。 【解決手段】本発明にかかる埋設処分施設11は、地下水の存在する地盤中に設けられ、内部に廃棄物12を埋設処分する施設であって、前記施設が難透水性の遮水層14で形成されてなり、前記遮水層14内面に複数のポーラス部材21が設けられてなり、前記ポーラス部材により遮水層へのガス領域の脈状侵入現象が確実に進展するので、より低圧でガスは難透水性の遮水層14を破過する。 【選択図】 図1
