Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, specifically to an ecological slope protection structure for ecological environment restoration. Background Technology

[0002] Slope restoration is a crucial component of ecological environment restoration projects. Traditional slope protection structures often utilize hard materials such as concrete and masonry, which, while stabilizing slopes, disrupt the continuity of the ecological environment and hinder vegetation growth and soil and water conservation. Furthermore, simple vegetation-based slope protection structures are prone to landslides and soil erosion on steep slopes or in poor soil conditions, indicating insufficient stability. Therefore, it is necessary to design a slope protection structure that can both ensure slope stability and promote ecological restoration. Utility Model Content

The water-permeable hose 201 has water-permeable holes with a diameter of 2-3mm on its wall and a hole spacing of 5-8cm.

[0009] As a further specific optimization of the technical solution of this utility model: the vegetation growth layer 3 is formed by stacking ecological bags 301, and the ecological bags 301 contain planting soil 302 containing planting soil, grass seeds and water-retaining agent, and the mass ratio of planting soil, grass seeds and water-retaining agent is 100:1:2.

[0010] As a further specific optimization of the technical solution of this utility model: the connecting and fixing component 4 includes a vertical fixing pile 401 and a horizontal connecting strip 402.

[0021] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Example 1

[0022] An ecological slope protection structure for ecological environment restoration includes a base reinforcement layer 1, a water storage and fertilizer retention layer 2, and a vegetation growth layer 3 laid sequentially from the bottom to the top of the slope 5. The base reinforcement layer 1 and the water storage and fertilizer retention layer 2, as well as the water storage and fertilizer retention layer 2 and the vegetation growth layer 3, are connected by connecting and fixing components 4.

[0023] The base reinforcement layer 1 includes a grid-like steel reinforcement framework 101 with a grid size of 30cm × 30cm and steel bars with a diameter of 6-8mm. The steel reinforcement framework 101 is filled with a mixture of gravel and sand 102, where the mass ratio of gravel to sand in the gravel-sand filling 102 is 3:1, and the gravel particle size is 2-5cm. The base reinforcement layer 1 is 20-30cm thick. Through the steel reinforcement framework 101 and the filling planting nutrient material 202, the overall stability of the slope 5 can be effectively improved, preventing slope 5 from collapsing.

[0024] The water-retaining and fertilizer-preserving layer 2 comprises a planting nutrient material 202 consisting of coconut coir wrapped in non-woven fabric and well-rotted organic fertilizer, with a volume ratio of coconut coir to well-rotted organic fertilizer of 2:1. Coconut coir has excellent water retention properties, while the well-rotted organic fertilizer provides nutrients for plant growth. The water-retaining and fertilizer-preserving layer 2 is 10-15cm thick and contains serpentine permeable hoses 201. The diameter of the permeable hoses 201 is 5-8mm, and the hose walls have permeable holes with a diameter of 2-3mm spaced 5-8cm apart. The permeable hoses 201 can drain excess water and also provide irrigation during droughts, ensuring the water needed for plant growth.

[0025] The vegetation growth layer 3 is composed of stacked eco-bags 301, which are made of polypropylene and have UV resistance and corrosion resistance. Each eco-bag 301 contains planting soil 302, which includes planting soil, grass seeds, and a water-retaining agent, with a mass ratio of 100:1:2. Suitable grass seeds include tall fescue and bermudagrass. The eco-bags 301 are 40cm x 60cm in size and are stacked in a staggered manner to form a stepped structure, which is beneficial for vegetation growth and soil and water conservation. The thickness of the vegetation growth layer 3 depends on the slope of the slope 5 and is generally 30-50cm.

[0026] The connecting and fixing component 4 includes vertical fixing piles 401 and transverse connecting strips 402. The vertical fixing piles 401 are threaded steel bars with a diameter of 8-10mm and a length of 50-60cm. Their lower ends are inserted into the slope 5 to a depth of no less than 30cm, and their upper ends protrude 35-10cm above the vegetation growth layer. The transverse connecting strips 402 are 5cm wide polyester fiber strips with high strength and wear resistance. The transverse connecting strips 402 are installed transversely along the slope 5, connecting and fixing adjacent vertical fixing piles 401 to form an integrated fixing system, further improving the stability of the slope protection structure. Example 2

[0027] Taking the repair project of slope 5 on a mountain highway as an example, the slope of slope 5 is 30°, the soil is sandy, and soil erosion is relatively serious. The ecological slope protection structure of this utility model was used for repair, and the specific steps are as follows:

[0028] 1. Clear weeds, gravel and other debris from the surface of slope 5 and level the slope 5.

[0029] 2. Laying the base reinforcement layer 1: First, lay a steel reinforcement cage 101 on the surface of slope 5. The mesh size of the steel reinforcement cage 101 is 30cm×30cm, and the diameter of the steel bars is 7mm. Then, fill the steel reinforcement cage 101 with a mixture of gravel and sand 102. The mass ratio of gravel to sand is 3:1, the gravel particle size is 3-4cm, and the laying thickness is 25cm.

[0030] 3. Laying Water-Retaining and Fertilizer-Conserving Layer 2: A non-woven fabric with a specification of 100g / ㎡ is laid on top of the base reinforcement layer 1. Then, coconut coir and well-rotted organic fertilizer are mixed evenly at a volume ratio of 2:1 and filled into the non-woven fabric to form a 12cm thick water-retaining and fertilizer-conserving layer 2. A permeable hose 201 with a diameter of 6mm is embedded inside the water-retaining and fertilizer-conserving layer 2. The hose has 2.5mm diameter permeable holes spaced 6cm apart, and the hoses are arranged in a serpentine pattern.

[0031] 4. Laying the vegetation growth layer 3: Use polypropylene ecological bags 301 with dimensions of 40cm×60cm, filled with planting soil 302 containing planting soil, grass seeds, and water-retaining agent. The mass ratio of planting soil, grass seeds, and water-retaining agent is 100:1:2. Stack the ecological bags 301 on top of the water-retaining and fertilizer-retaining layer 2, staggering adjacent ecological bags 301 to form a stepped structure, with a thickness of 40cm.

[0032] 5. Install the connecting and fixing component 4: Use a 9mm diameter, 55cm long threaded steel bar as a vertical fixing pile 401, penetrating through the base reinforcement layer 1, the water and fertilizer retention layer 2, and the vegetation growth layer 3, with the lower end inserted 35cm into the slope 5 and the upper end protruding 38cm from the vegetation growth layer. Then, use a 5cm wide polyester fiber strip as a transverse connecting strip 402, set transversely along the slope 5, to connect and fix adjacent vertical fixing piles 401, with the transverse connecting strips 402 spaced 1m apart.

[0033] After the project was completed, and following a six-month observation period, slope 5 showed good stability with no landslides or collapses. The tall fescue within eco-bag 301 grew vigorously, achieving a coverage rate of over 90%, demonstrating significant soil and water conservation effects and effective ecological restoration.
