发明名称 Method and apparatus for applying a daily cover to dumped waste
摘要 A method and apparatus for applying a "daily cover" to the working face of a landfill. A sheet-like member preferably of imperforate construction such as canvas and the like is positioned at the end of a working day at one edge of the working face such that one edge of the member is adjacent thereto. The member is then fixed to the landfill and then unrolled to its extended position to cover at least a significant portion of the working face and thus obviate the need for a conventional "daily cover" in the form of six inches to two feet of compacted earth.
