Problems solved by technology

However, the spray covering uses a lot of organic materials, which are easy to burn
Clay is used as covering material in CN201010213155 and CN200810069470, but the utilization rate of the material is low, and there are still half of the flammable organic materials

Abstract

The invention discloses a refuse landfill surface covering material and an application thereof. The refuse landfill surface covering material consists of a gel adhesive, aggregates, a foaming agent, a surfactant and a viscosity regulator. The refuse landfill surface covering material has characteristics of being low in cost, environment-friendly, less in organic substance content, convenient to construct, and the like; and the refuse landfill surface covering material is applied to covering the refuse landfill surface, less in dosage, good in sealing effect, low in cost and capable of being widely popularized and used.

Description

technical field [0001] The invention relates to a landfill surface covering material and its application, belonging to the technical category of environmental protection. Background technique [0002] In my country's "Technical Specifications for Municipal Solid Waste Sanitary Landfill (CJJ17-2004)", it is required that landfill waste should be operated in units and layers. After the completion of each unit operation, daily coverage should be carried out. The thickness of the covering layer is determined according to the covering material. The thickness of the soil covering layer is 20-25cm; For intermediate covering, the thickness of the covering layer is determined according to the covering material, and the thickness of the soil covering layer is greater than 30cm. When the landfill reaches the design closure conditions, it shall be covered finally, and the thickness of the covering layer shall be 90cm. The materials used for garbage covering should take into account th...
