Background: In social and economic development, infrastructure construction plays an important role that cannot be ignored. According to the national highway construction plan, a highway network of 400,000 kilometers will be built by 2030. While the construction and development of highways drive economic development, it also causes serious impact and damage to the ecological environment. Especially in some areas with strict requirements on ecological and environmental conditions, once the ecological environment is damaged, it will be difficult to restore. Because of its poor ventilation and water permeability, it is cut off from the outside world, making it unable to meet people's needs for ecological environment and high-quality life; on the other hand, traditional concrete masonry has a lot of consumables and high cost. It can be seen that it is urgent to improve the current slope protection.

 Introduction  to the results: Ecological concrete is an ecological restoration engineering technology suitable for use in the fields of water conservancy engineering and environmental engineering. It adopts high-cohesive admixture and active mixture composite technology to make its mechanical properties meet the engineering requirements, and at the same time, it has similar water permeability and air permeability to soil. It is suitable for green plant growth. At the same time, through configuration design, prefabricated into spherical, rectangular, spherical and other blocks, which can greatly improve the ecological effect of the water-land ecotone and the water quality purification ability. It is an upgrading technology for slope protection of water conservancy projects and has excellent industrialization prospects.

 Technical characteristics: As a cutting-edge research technology that can effectively improve the slope protection environment, plant ecological concrete slope protection technology has attracted much attention from all walks of life. Vegetation ecological concrete is composed of coarse aggregate, cementitious material, admixture and water. Through the cementation effect of the cementitious material, the coarse aggregate is wrapped to form a whole. It has the characteristics of high strength, good water permeability and air permeability. It can be planted on its surface in the later stage and is a new type of environmentally friendly material. Scholars at home and abroad have conducted a series of research on the technology of plant-growing ecological concrete slope protection and achieved certain results. At present, planting ecological concrete slope protection technology has been widely used in many Western countries. Japan was the first to conduct research on ecological concrete as an ecological material, achieved a lot of results, and formed relatively mature production and construction techniques. In the early 21st century, European and American countries first applied it to non-load-bearing structures and permeable pavements and other facilities. Later, California, the United States conducted research on the compatibility of ecological concrete with certain flowers and plants. It was found that these flowers and plants could grow on ecological concrete and achieve good landscape greening effects. Compared with ordinary concrete slope protection, ecological concrete slope protection has good erosion resistance.
