Abstract
Official abstract text for this publication.
A landfill soil cover system is proposed for preventing water infiltration into a landfill and gas emission from the landfill under all weather conditions. The landfill cover system comprises three soil layers; namely, a clay layer, a gravelly sand layer and a silt layer, compacted successively from the bottom to the top of the system. The clay layer is compacted immediately above an optional gas collection layer and landfill waste at an optimum water content. Additionally, a trench for water drainage may be constructed, for example, every 20-40 m in the horizontal direction. Water infiltration and landfill gas emission can be prevented effectively by this landfill soil cover system under any humid, semi-arid and arid climates.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for covering landfills, the method comprising: preparing a flat or sloping surface of landfill waste; depositing and compacting a clay layer over the surface of the landfill waste at an optimum water content of the clay; depositing and compacting a gravelly sand layer above the clay surface; depositing and compacting a silt layer above the gravelly sand surface, the depositing of the layers comprises introducing an additional layer of compac…
