Refuse landfill evapotranspiration covering structure and preparation method
The invention relates to an evapotranspiration covering structure of a refuse landfill. The evapotranspiration covering structure is sequentially provided with a vegetation nutrient soil layer, a water storage soil layer and a foundation soil layer from top to bottom. Wherein the water storage soil layer is modified dredged sludge formed by uniformly stirring dredged sludge, engineering muck II, fly ash, slag and an alkali activator. The method has the beneficial effects that the dredged sludge and the engineering residue soil II used for the water storage soil layer are engineering waste residues to be treated urgently, the obtaining way is wide, and the cost is low; the slag and the fly ash are bulk industrial solid wastes, the stock is large, the utilization rate is low, resource utilization of the solid wastes can be realized by using the engineering waste residues and the industrial solid wastes to prepare the modified dredged sludge, and the construction cost is relatively low.
本发明涉及一种垃圾填埋场腾发覆盖结构，从上至下依次布置有如下结构：植被营养土层、储水土层和基础土层；其中,所述储水土层为疏浚淤泥、工程渣土Ⅱ、粉煤灰、矿渣和碱激发剂搅拌均匀后形成的改性疏浚淤泥。本发明的有益效果是：用于储水土层的疏浚淤泥和工程渣土Ⅱ均为亟待处理的工程废渣，获得途径广、成本低；矿渣、粉煤灰为大宗工业固废，存量多、利用率低，使用工程废渣和工业固废制作改性疏浚淤泥可实现固废资源化利用，建设成本相对较低。
