Description

Technical Field

[0001] The utility model relates to the technical field of slope protection structures, in particular to a surface greening protection slope structure. Background Art

[0002] The greening of highway slopes not only impacts the effectiveness of highway use but also reflects the state of a city's development. The goal of slope greening is to combine vegetation with civil engineering techniques to enhance the aesthetics of highways while further strengthening their corrosion resistance and extending their service life.

[0003] One of the principles of highway slope greening is the hydrological effect of vegetation. By covering highway slopes with vegetation, it is possible to protect the slopes, prevent soil erosion, and improve the quality of the ecological environment. Hydrological effect refers to the regulation of water circulation and distribution by vegetation through processes such as root water absorption, transpiration, and rainwater interception. In highway slope greening, vegetation can play a role in water absorption and soil stability. This is because the roots of vegetation absorb water from the soil, reducing its moisture content, thereby lowering soil saturation, enhancing its resistance to erosion, and maintaining slope stability.

[0004] Highway slope greening not only leverages the hydrological effects of vegetation but also its mechanical properties. First, vegetation cover acts as a slip-resistant slope protection. Vegetation roots firmly anchor soil particles, increasing the soil's shear strength, thereby improving slope stability and resistance to slippage. Vegetation roots penetrate the soil, forming a network structure that prevents soil loosening and landslides. Furthermore, the roots increase soil cohesion and internal friction, enhancing shear strength and reducing the risk of landslides.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further explained below with reference to the accompanying drawings and specific implementation methods.

[0025] like Figure 1 As shown, the utility model proposes a surface greening protection slope structure, which includes a slope body 1 having a slope surface 2 and a flat slope surface 3.

[0026] like Figure 1 and 2 As shown, the slope surface 2 is provided with a plurality of circular cross-section anchor holes 4, each of which is inserted with a grouting anchor rod 5, the head of which protrudes from the anchor hole 4. A wire mesh 6 is laid on the slope surface in a crisscross pattern, with the wires of the wire mesh 6 being secured to the heads of the grouting anchor rods 5 by tying wire. The grouting anchor rods 5 press the wire mesh 6 against the slope surface 2, thereby stabilizing the slope surface 2.

[0027] like Figure 1 and 2 As shown, a slope base material mixture layer 7 is laid on the slope surface 2. The slope base material mixture layer 7 is composed of a mixture of greening base material, fiber, planting loam, organic fertilizer, and compound fertilizer. The greening base material is made of organic matter and soil structure improver, the fiber is made of straw and branches crushed into 10-15 mm length, and the planting loam is the original surface soil of the project site or the loam of nearby farmland that has been air-dried and sieved.

[0028] After the slope base material mixture layer 7 is laid, vegetation seeds are sown. The vegetation seeds should be tested for germination rate before use. They can only be used when the germination rate reaches more than 90%. Vegetation seeds that are difficult to germinate should be germinated before use. After the vegetation seeds germinate, a slope vegetation layer 8 will be formed and cover the surface of the slope base material mixture layer 7.

[0029] like Figure 1 and 3 As shown, a groove 9 is opened on the flat slope surface 3, and the groove 9 is opened along the extension direction of the slope body 1. A plurality of planting boxes 10 are embedded in the groove 9. The planting boxes 10 are prefabricated. A planting room 11 is opened on the top surface of the planting box 10. The planting room 11 is provided with a geotextile 12, a flat slope base material mixture layer 13, and a flat slope vegetation layer 14 from bottom to top.

[0030] Geotextile 12, also known as filtration geotextile 12, is a permeable geosynthetic material made from synthetic fibers through needlepunching or weaving. It offers advantages such as high strength, corrosion resistance, good water permeability, and excellent antimicrobial properties. The filtration function of geotextile 12 allows liquid to pass through while retaining soil particles under osmotic pressure.

[0031] The flat slope base material mixture layer 13 is a mixture of greening base material, fiber, planting loam, organic fertilizer, and compound fertilizer. The greening base material is made of organic matter and soil structure improver, the fiber is made of straw and branches crushed into 10-15 mm length, and the planting loam is the original surface soil of the project site or the loam of nearby farmland that has been air-dried and sieved.

[0032] After the flat slope base material mixture layer 13 is laid, vegetation seeds are sown. The vegetation seeds should be tested for germination rate before use. They can only be used when the germination rate reaches more than 90%. Vegetation seeds that are difficult to germinate should be germinated before use. After the vegetation seeds germinate, a flat slope vegetation layer 14 will be formed and cover the surface of the flat slope base material mixture layer 13.

[0033] The surface greening protection slope structure is provided with a slope vegetation layer 8 on the slope surface 2 of the slope body 1 and a flat slope vegetation layer 14 on the flat slope surface 3 of the slope body 1, and has a high greening rate.

[0034] like Figure 3 As shown, a water storage chamber 15 is defined within the planting box 10 and is located directly below the planting chamber 11. A partition 16 is provided between the water storage chamber 15 and the planting chamber 11. The partition 16 has multiple water holes 17 connecting the water storage chamber 15 and the planting chamber 11. A water-absorbing core 18, constructed of a cotton strip, is located within the planting box 10. The upper end of the core 18 is positioned within the flat-slope substrate mixture layer 13, and the lower end of the core 18 extends through the geotextile 12, through the water holes 17, and into the water storage chamber 15.

[0035] When the planting box 10 is working, rainwater or irrigation water falls on the flat slope substrate mixture layer 13 and will seep downwards. The water passes through the geotextile 12 and the water holes 17 in sequence and falls into the water storage chamber 15. When the water content of the flat slope substrate mixture layer 13 is low, the water absorption core 18 absorbs the water in the water storage chamber 15 to increase the water content of the flat slope substrate mixture layer 13, so that the flat slope substrate mixture layer 13 can be kept moist but not waterlogged.

[0036] like Figure 3 and 4 As shown, a flange groove 19 and a valve hole 20 are sequentially opened downward on the bottom wall of the water storage chamber 15 . A water level valve 21 is arranged in the valve hole 20 . The water level valve 21 includes a valve body 22 and a valve cover 23 .

[0037] The valve body 22 is plugged into the valve hole 20. A valve flange 24 extends outward from the top of the outer wall of the valve body 22. The valve flange 24 engages with the flange groove 19 and is screwed to the planting box 10. A water inlet valve hole 25 is defined on the top surface of the valve body 22. The water inlet valve hole 25 is a circular hole that communicates with the water storage chamber 15. An inner valve groove 26 is defined on the bottom surface of the valve body 22. The inner valve groove 26 is circular in cross section, and its diameter is larger than that of the water inlet valve hole 25. The valve cover 23 is screwed to the bottom surface of the valve body 22. A guide hole 27 is defined through the middle of the valve cover 23. The guide hole 27 is located within the circular hole and communicates with the inner valve groove 26.

[0038] like Figure 4 and 5 As shown, a disc-shaped lift valve disc 28 slides within the inner valve groove 26. A lift valve head 29 is fixedly connected to the end surface of the lift valve disc 28 facing the water inlet valve hole 25. The lift valve head 29 engages with the water inlet valve hole 25. When the lift valve head 29 is inserted into the water inlet valve hole 25, water is unable to flow downward through the water inlet valve hole 25. When the lift valve head 29 descends and separates from the water inlet valve hole 25, water flows downward through the water inlet valve hole 25.

[0039] like Figure 4 and 5 As shown, a water riser cover 30 is fixedly connected to the end surface of the lift valve disc 28 facing the guide opening 27. The water riser cover 30 passes through the guide opening 27 and slidably engages with the guide opening 27. A water outlet valve hole 31 is defined on the bottom surface of the water riser cover 30. This circular hole extends into the lift valve head 29. Four communication holes 32 are equidistantly defined on the outer wall of the lift valve head 29. These communication holes 32 are fan-shaped in cross section and communicate with the water outlet valve hole 31. Water entering the inner valve slot 26 can then enter the water outlet valve hole 31 through the communication holes 32.

[0040] like Figure 4 and 5 As shown, the lift valve disc 28 is provided with four circular guide post holes 33, which are equally spaced around the circumference. Four cylindrical posts 34 are fixedly connected to the end surface of the valve cover 23 facing the inner valve slot 26. These posts 34 are equally spaced around the circumference, with their top surfaces abutting the top wall of the inner valve slot 26. The four posts 34 extend through the four guide post holes 33, forming a sliding fit with the posts 34. This allows the lift valve disc 28 to perform relatively stable reciprocating linear motion up and down within the inner valve slot 26.

[0041] like Figure 4 and 5As shown, each column 34 is provided with a return spring 35, one end of the return spring 35 is against the end surface of the lifting valve disc 28 facing the valve cover 23, and the other end is against the end surface of the valve cover 23 facing the lifting valve disc 28. The return spring 35 is used to push the lifting valve disc 28 and the lifting valve head 29 upward, so that the lifting valve head 29 can block the water inlet valve hole 25.

[0042] like Figure 1 As shown, a drainage pipe 36 embedded in the groove 9 is provided below the planting box 10 , and a drainage inlet 37 is provided on the top surface of the drainage pipe 36 , and the drainage inlet 37 is communicated with the water outlet valve hole 31 .

[0043] The surface greening protection slope structure is advantageous in preventing excessive water from being stored in the water storage chamber 15 by providing the water level valve 21 .

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
