Anti-washout ecological greening protective face of refuse landfill side slope and construction method for anti-washout ecological greening protective face

Abstract

The invention discloses an anti-washout ecological greening protective face of a refuse landfill side slope. The anti-washout ecological greening protective face comprises a to-be-greened refuse landfill side slope, wherein a geomembrane fixedly covers the refuse landfill side slope; a three-dimensional geomat fixedly covers the geomembrane; and a mixture of greening seeds and a soil body is laid in the three-dimensional geomat. Meanwhile, the invention also discloses a construction method for the ecological greening protective face. The anti-washout ecological greening protective face and the construction method thereof disclosed by the invention solve the problems that a highly-polluted soil body of a refuse landfill is not suitable for plant growth and the planting soil body on the side slope cannot be kept and cannot form a green ecological side slope.

Description

technical field [0001] The invention relates to an anti-scouring ecological greening protection surface of a waste landfill slope and a construction method thereof, belonging to the technical field of waste landfill treatment. Background technique [0002] The slope treatment of the landfill is an important issue in the design and operation of the landfill. Under normal circumstances, most of the landfills are located in the suburbs near densely populated cities, which increases the risk of slope instability, loss, and collapse of highly polluted waste. Different degrees of degradation, uneven shear strength of the soil, and changes in the physical properties of the soil itself. Therefore, there are problems with a single common slope support measure, such as only blocking the soil but not high-pollution liquids. Seepage, the originally suitable slope strength will begin to weaken or even change dramatically over time. In fact, due to the difference in landfill time, the p...

AI Technical Summary

Problems solved by technology

Under normal circumstances, most of the landfills are located in the suburbs near densely populated cities, which increases the risk of slope instability, loss, and collapse of highly polluted waste bodies, and there are organic matter in landfills Different degrees of degradation, uneven shear strength of the soil, and changes in the physical properties of the soil itself. Therefore, there are problems with single and ordinary slope support measures, such as only blocking the soil but not high-pollution liquids. Seepage, the originally suitable slope strength will begin to weaken or even change dramatically over time, etc.

In fact, due to the difference in landfill time, the physical characteristics of the waste bodies in the bottom and top of the landfill are not clear, and the use of a single slope protection cannot meet the requirements for slope treatment of highly polluted landfills

In addition, for the special environment of the landfill, among the existing slope treatment methods, there are almost no effective measures for greening and environmental protection in the slope of the landfill.
