Greening concrete material for fixing soil and improving ecological environment and preparation method thereof

Abstract

The invention discloses a greening concrete material for fixing soil and improving ecological environment and a preparation method of the greening concrete material. The greening concrete material comprises a bottom layer concrete material and a surface layer concrete material, the purposes of soil fixation and ecological environment improvement are achieved in the mode that the bottom layer and the surface layer are combined, rainwater drainage and dust and organic matter storage to bottom layer soil are facilitated through the macroporous capacity storage effect of bottom layer large-aperture concrete, and the polypropylene fiber material has the advantages of being excellent in acid resistance and alkali resistance and good in tensile strength; by using the polypropylene fiber material, the wrapping and gripping force and the crack resistance of the concrete are improved, and the performance of the bottom layer concrete is improved; according to the surface layer, a layer of greening concrete used for improving the ecological environment covers the surface layer of large-aperture concrete, when root systems pass through, nutrients are obtained, growth is facilitated, meanwhile, the plant root systems grow to the concrete bottom layer through pores to be tightly combined with soil, the corrosion resistance is further exerted, and the soil fixation effect is achieved for preventing water and soil loss, and the greening purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of greening engineering materials, in particular to a greening concrete material for fixing soil and improving ecological environment and a preparation method thereof. Background technique [0002] In desertification, sandy desertification, soil salinization, soil erosion, etc. are very serious, which greatly limit the economic development of desertified areas and the improvement of people's living standards. The main causes of desertification are divided into natural factors and human factors. Drought and windy factors have dealt a fatal blow to the originally fragile ecological environment. The evaporation of farmland has accelerated the accumulation of salt, and the barren land has deteriorated further with the drought. Heavy rains can also cause desertification. In arid areas with poor vegetation and fragile land , the resistance to rainfall is weak, and soil erosion is prone to occur; human factors, ind...

Problems solved by technology

[0002] In desertification, sandy desertification, soil salinization, soil erosion, etc. are very serious, which greatly restricts the economic development of desertified areas and the improvement of people's living standards. The main causes of desertification are divided into natural factors and human factors. Among the factors, drought and wind have caused a fatal blow to the fragile ecological environment. The evaporation of farmland has accelerated the accumulation of salt, and the barren land has deteriorated further with the drought. Heavy rains can also cause desertification. In arid areas with poor vegetation and fragile land , the resistance to rainfall is weak, and soil erosion is prone to occur; human factors, industrial progress and rapid development of infrastructure have also brought certain damage and impact to the ecological environment, resulting in vegetation destruction and soil erosion in some areas. The imbalance of the natural ecosystem, as well as human activities such as population surge and improper use of natural resources, such as overgrazing, deforestation, unreasonable farming and extensive management, and unreasonable use of water resources, have all destroyed the ecosystem. Therefore, it leads to the desertification of the land. Under the premise of this background condition, it is very necessary to invent a kind of greening concrete material and its preparation method for fixing soil and improving ecological environment.
