Description

An ecological concrete slope protection structure Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to an ecological concrete slope protection structure. Background Technology

[0002] With the development of infrastructure construction, the demand for slope protection engineering is increasing. Traditional slope protection technologies mainly include masonry slope protection and concrete slope protection. Although these technologies have certain protective effects, they also have problems such as ecological damage and poor landscape effect. In recent years, ecological slope protection technology has gradually gained attention, aiming to achieve the protection function while taking into account ecological restoration and landscape beautification. However, existing ecological slope protection technologies still have shortcomings in terms of strength, durability and ecological adaptability, making it difficult to meet the long-term protection needs in complex environments.

[0003] A search revealed Chinese Patent Publication No. CN220468894U, which discloses a vegetation-concrete ecological slope protection fixing structure. This structure includes an ecological slope protection netting with two fixing blocks on it. Each fixing block has a positioning structure, including anchor bolts fixedly connected to the lower surface of the fixing block. A connecting block with a T-shaped cross-section is also fixedly connected to the outer surface of the fixing block. This vegetation-concrete ecological slope protection fixing structure can also protect the ecological slope by blocking soil clods and gravel, preventing them from rolling down the slope and increasing the safety of the fixing structure. The blocking blocks also provide some protection against rainwater and soil, preventing landslides and soil erosion during rainfall, thus ensuring the stability of the grass seed production environment. However, the ecological effects of this structure are limited, with slow vegetation recovery and a low survival rate. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an ecological concrete slope protection structure, which aims to improve the problems of limited ecological effects, slow vegetation recovery, and low survival rate in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ecological concrete slope protection structure, comprising a soil slope, a filter layer on the top surface of the soil slope, a vegetation induction layer on the top surface of the filter layer, a water-retaining and moisture-retaining layer on the top surface of the vegetation induction layer, a biological habitat cave layer on the top surface of the water-retaining and moisture-retaining layer, a nutrient slow-release layer on the top surface of the biological habitat cave layer, anchor rods fixedly connected to the outer wall of the soil slope, and a protective concrete structure on the top surface of the soil slope, the protective concrete structure being used to reinforce the structure.

[0006] The above technical solution involves: a filter layer on the top surface of the slope to filter out impurities from the water while allowing water to pass through smoothly, thus protecting the underlying soil structure; a vegetation induction layer on top of the filter layer to promote root growth, guide roots deep into the soil, and enhance slope stability; a water-retaining and moisture-retaining layer on top of the vegetation induction layer to retain soil moisture and provide a continuous water supply for plants, especially during dry seasons; a biological habitat cave layer on top of the water-retaining and moisture-retaining layer to provide habitats for various organisms, increasing biodiversity, and the activities of these organisms also contribute to soil loosening and fertility improvement; a nutrient slow-release layer on top of the biological habitat cave layer to slowly release nutrients, providing continuous nutrient supply for plants and other organisms; and anchor bolts fixedly connected to the outer wall of the slope to enhance overall structural stability, with the anchor bolts penetrating deep into the slope to form a firm bond, greatly improving the structure's resistance to sliding.

[0007] As a further description of the above technical solution:

[0008] The protective concrete structure includes a concrete block, the bottom surface of which is attached to the top surface of the slope.

[0011] A fitting block is fixedly connected to the bottom of the outer wall of the concrete block, and a groove is provided on the top surface of the fitting block.

[0012] The above technical solution involves a mating block 1 fixedly connected to the bottom of the outer wall of the concrete block. The top surface of the mating block 1 has a groove, which, when combined with subsequent components, can increase the stability and strength of the structure.

[0013] As a further description of the above technical solution:

[0014] A second fitting block is fixedly connected to the top of the outer wall of the concrete block, and a protrusion is fixedly connected to the bottom surface of the second fitting block.

[0015] The above technical solution involves a second mating block fixedly connected to the top of the outer wall of the concrete block, and a protrusion fixedly connected to the bottom surface of the second mating block, which can increase the stability and strength of the structure.

The vegetation induction layer is a fiber mesh pre-filled with a mixture of plant seeds and nutrient soil. The fiber mesh can guide the plant roots to grow in a directional manner, providing extra protection and nutrients for the early stage of seed germination. The water retention and moisture-retaining layer can absorb and store a large amount of water during rainfall and release it slowly during drought, providing continuous water supply for vegetation growth and reducing water evaporation and loss. The biological habitat cave layer provides habitat space for insects and small reptiles, promoting the development of biodiversity. The nutrient slow-release layer is made of slow-release material rich in various nutrients and is set in the planting soil layer. It can slowly release nutrients, providing a stable source of nutrition for the long-term growth of vegetation and reducing the cost of later fertilization and maintenance.
