Description

Technical Field

[0001] This application relates to the technical field of slope greening structures, and more particularly to a landscape greening system for steep rock slopes in high-temperature areas. Background Technology

[0002] In plateau regions, steep rock slopes with low surface soil cover and weak vegetation growth conditions make it difficult to restore ecological balance through natural growth. Exposed rock slopes, influenced by topography, meteorology, hydrology, and engineering excavation, are prone to geological disasters such as collapses, landslides, rockfalls, and rockfalls when the main structural planes are connected, posing a serious threat to pedestrians and vehicles. Taking engineering measures to quickly green rock slopes, while ensuring slope stability, can reduce the threat of geological disasters to people's lives and property, while mitigating ecological degradation and beautifying the environment, aligning with current sustainable development requirements.

[0003] Revegetation of rock slopes is an ecological restoration method guided by theories from geology, soil and water conservation, and botany, and is tailored to slope management of different rock types. Currently, commonly used greening methods for rock slopes mainly include hydroseeding and climbing plant planting.

[0004] For steep rock slopes, the methods described above still have many shortcomings in terms of vegetation cover, irrigation, and ecosystem restoration. For example, with hydroseeding, soil fixation is difficult, vegetation is not drought-tolerant, and the soil is infertile, resulting in insufficient water and fertilizer supply to the vegetation and a low survival rate due to the lack of long-term greening effect. With climbing plant greening, the method is affected by groundwater and surface water on the rock slope, leading to uneven vegetation growth, high difficulty in subsequent vegetation maintenance, and low vegetation survival rate, which greatly affects the greening effect of the slope. Summary of the Invention

[0005] In order to improve the survival rate of vegetation on rock slopes and enhance the greening effect of rock slopes, this application proposes a landscape greening system for steep rock slopes in high-temperature areas.

[0006] This application proposes a landscape greening system for steep rock slopes in high-temperature areas, employing the following technical solution:

[0007] A landscape greening system for steep rock slopes in high-temperature areas includes:

[0008] A planting module is set on the first walkway of a rocky slope. The planting module includes a water interception ditch, a planting trough and a drainage ditch. The planting trough includes a surface layer, a wetting layer and a water-retaining layer arranged from top to bottom. The bottom of the water interception ditch is connected to the water-retaining layer. The drainage ditch is connected to the wetting layer through a first drainage channel and to the water interception ditch through a second drainage channel.

[0009] A slope protection module is installed below the planting module. The slope protection module includes a coconut blanket installed on the surface of the rock slope and a small drainage pipe installed in the same direction as the coconut blanket. The small drainage pipe is connected to the drainage ditch through drainage holes on the drainage ditch, and the small drainage pipe is provided with multiple surface pores.

[0010] Preferably, a water-retaining sill is provided between the drainage ditch and the intercepting ditch, and the drainage ditch, the water-retaining sill, and the intercepting ditch constitute the second drainage channel;

[0011] When the water level in the intercepting ditch reaches the height of the water-retaining sill, the water in the intercepting ditch overflows from the water-retaining sill into the drainage ditch.

[0012] Preferably, the height of the water-retaining sill is the same as the height of the water-retaining layer.

[0013] Preferably, the top of the intercepting ditch is flush with the top of the surface layer.

[0014] Preferably, the first drainage channel is disposed on the side of the impregnation layer near the drainage ditch, and the height of the first drainage channel is higher than the bottom of the impregnation layer;

[0015] When the water level in the wetting layer is higher than the lowest point of the first drainage channel, the water in the wetting layer overflows from the first drainage channel into the drainage ditch.

[0016] Preferably, multiple small drain pipes are spaced apart, with one end of each small drain pipe communicating with the drain hole and the other end extending away from the drain hole to the bottom of the coconut fiber mat.

[0017] Preferably, the number of drainage holes is greater than the number of the tiny drainage pipes.

[0018] Preferably, the narrow drain pipe is configured in a curved shape.

[0019] Preferably, the system further includes a sun protection module, the sun protection module comprising:

[0020] A sun-protective curtain set above the coconut fiber blanket;

[0021] The upper and lower supports of the sunshade curtain are fixed.

One side of the lower support is fixed to the bottom of the coconut blanket, and the other side extends horizontally away from the coconut blanket.

[0022] Preferably, the upper support has an upward climbing hole, and the lower support has a downward hanging hole.

[0023] This application provides a landscape greening system for steep rock slopes in high-temperature areas, which has the following technical effects:

[0024] 1. The soil in the planting troughs on the walkways of each platform is layered to ensure that the water-retaining layer in the planting trough is always filled with water, which is conducive to the absorption of water and fertilizer by plants and improves the survival rate of vegetation.

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following description, with reference to the accompanying drawings, describes an embodiment of a landscape greening system for steep rock slopes in high-temperature areas.

[0039] Reference Figure 1 This application discloses a landscape greening system for steep rock slopes in high-temperature areas, comprising:

[0040] The planting module is set on the first walkway of the rock slope 15. The planting module includes a water interception ditch 4, a planting trough 3 and a drainage ditch 5. The planting trough 3 includes a surface layer 301, an infiltration layer 302 and a water retention layer 303 arranged from top to bottom. The bottom of the water interception ditch 4 is connected to the water retention layer 303. The drainage ditch 5 is connected to the infiltration layer 302 through a first drainage channel and to the water interception ditch 4 through a second drainage channel.

[0041] The slope protection module is set below the planting module. The slope protection module includes a coconut blanket 8 set on the surface of the rock slope 15 and a small drainage pipe 9 set in the same direction as the coconut blanket 8. The small drainage pipe 9 is connected to the drainage ditch 5 through the drainage hole 7 on the drainage ditch 5. The small drainage pipe 9 is provided with multiple surface holes.

[0042] Reference Figure 2 In this embodiment, the soil in the planting trough 3 is divided into three layers from top to bottom: a surface layer 301, a wetting layer 302, and a water-retaining layer 303. The water-retaining layer 303 is always filled with water to ensure that the roots of the vegetation 1 are not short of water. The wetting layer 302 facilitates the drainage of water in the planting trough 3 into the drainage ditch 5, preventing the vegetation 1 from drowning due to excessively high water levels in the planting trough 3. The surface layer 301 is dry, and the surface covering reduces the evaporation of water from the underlying soil while providing sufficient nutrients for the vegetation 1. At the same time, grasses 2 are planted in the gaps between the vegetation 1 in the surface layer 301 to further reduce soil moisture evaporation and soil erosion.

[0043] Interception ditches 4 are installed on the side of the walkway near the mountain at each level platform, and drainage ditches 5 are installed on the open side. The bottom of the interception ditches 4 is connected to the planting troughs 3, allowing surface water to drain into the planting troughs 3 through the interception ditches 4. The drainage ditches 5 are connected to the saturation layer 302 through a first drainage channel to drain excess water from the saturation layer 302. In addition, the drainage ditches 5 are also connected to the interception ditches 4 through a second drainage channel, so that excess water in the interception ditches 4 can be drained after the water-retaining layer 303 is filled with water.

[0044] Specifically, the first drainage channel is located on the side of the impregnation layer 302 near the drainage ditch 5, and the height of the first drainage channel is higher than the bottom of the impregnation layer 302; when the water level in the impregnation layer 302 is higher than the lowest point of the first drainage channel, the water in the impregnation layer 302 overflows from the first drainage channel into the drainage ditch 5.

[0045] Specifically, in one embodiment of this example, the length of the planting trough 3 is set according to the platform walkway, the width can be set to 1 to 1.2m, the depth can be 70 to 80cm, and the soil thickness of each layer of the surface layer 301, the impregnation layer 302 and the water-retaining layer 303 in the planting trough 3 is controlled to be 20cm.

[0046] The drainage ditch 4 has a bottom width of 30cm and a height of 60cm. The height is flush with the top of the surface layer 301 in the planting trough 3. The bottom of the ditch 4 is left open by 20cm on the side close to the planting trough 3, which is connected to the planting trough 3 to supply water to the bottom water-retaining layer 303 in the planting trough 3, ensuring that the water-retaining layer 303 always has water.

[0047] The drainage ditch 5 is 30cm wide at the bottom and 40cm high. The side closest to the planting trough 3 is connected to the immersion layer 302, facilitating the drainage of water from the planting trough 3 into the drainage ditch 5 through the first drainage channel. This ensures that water flows through the immersion layer 302 without stagnant water, preventing the vegetation 1 from drowning due to excessive water intake. Therefore, no water seeps into the surface soil layer 301, which serves to provide nutrient soil while reducing water evaporation from the immersion layer 302 and the water-retaining layer 303.

[0048] Reference Figure 3 In one embodiment of this example, a water-retaining sill 6 is provided between the drainage ditch 5 and the intercepting ditch 4. The drainage ditch 5, the water-retaining sill 6 and the intercepting ditch 4 constitute a second drainage channel. When the water level in the intercepting ditch 4 reaches the height of the water-retaining sill 6, the water in the intercepting ditch 4 overflows from the water-retaining sill 6 into the drainage ditch 5.

[0049] Specifically, the two ends of the drainage ditch 5 are connected to the intercepting ditch 4, and a water-retaining sill 6 is installed at each connection point. The bottom of the intercepting ditch 4 is connected to the water-retaining layer 303 of the planting trough 3, allowing surface water to drain into the water-retaining layer 303 through the intercepting ditch 4. It is worth mentioning that the height of the water-retaining sill 6 is the same as the height of the water-retaining layer 303, thus ensuring that water can only be drained into the drainage ditch 5 after the water-retaining layer 303 is full of water.

[0050] For example, on the same platform walkway, the intercepting ditch 4 and the drainage ditch 5 are connected at both ends of the planting trough 3, and a 20cm high water-retaining sill 6 is arranged at the connection. When the water in the intercepting ditch 4 is below 20cm, it can all enter the water-retaining layer 303 in the planting trough 3. When the water in the intercepting ditch 4 exceeds 20cm, it passes over the water-retaining sill 6 and flows into the drainage ditch 5.

[0051] Furthermore, a row of drainage holes 7 is arranged at the bottom of the drainage ditch 5 on the free side of the platform walkway. The diameter of the drainage holes 7 is 5-8cm. When the water in the intercepting ditch 4 crosses the water-retaining sill 6, it enters the drainage ditch 5. The water in the drainage ditch 5 enters the slope protection module through the drainage holes 7.

[0052] Reference Figure 1 and Figure 4 In the slope protection module, coconut fiber mats 8 are laid on the slope surface to protect the steep rock slope 15 from wind and stabilize the soil, ensuring that the slope surface is covered with soil. Small drainage pipes 9 are installed along the direction of the coconut fiber mats 8. Excess water from the platform walkway enters the water pipes through the drainage holes 7 at the bottom of the drainage ditch 5. Under the action of water pressure, the small water pipes spray outward through the surface pores to the slope of the rock slope 15, providing water to the climbing plants 16 on the steep slope and preventing the plants from dying due to lack of water.

[0053] More specifically, multiple small drain pipes 9 are spaced apart. One end of each small drain pipe 9 is connected to a drain hole 7, and the other end extends away from the drain hole 7 to the bottom of the coconut fiber mat 8. The number of drain holes 7 is greater than the number of small drain pipes 9. The small drain pipes 9 are configured in a curved shape.

[0054] Specifically, the small drainage pipes 9 can be designed in a wavy shape. At both ends of the small drainage pipes 9 at the same elevation, they are fixed to the inside of the sunshade curtain 12 near the slope using fixing ends 901. At the middle of the same elevation, they are fixed to the frame of the sunshade curtain 12 using clips 902. The small drainage pipes 9 at the bottom of the drainage holes 7 are arranged at intervals. Therefore, water without small drainage pipes 9 at the bottom of the drainage holes 7 flows directly from the bottom to the slope surface of the rock slope 15, providing moisture to the vegetation 1 near the same level platform walkway.

[0055] The steep rock slope 15 typically has a slope of ≥60° and little soil on its surface. Therefore, the survival rate of vegetation 1 is low in the early stages due to strong sunlight, resulting in exposed rock slope 15, which affects the visual effect. At the same time, due to the lack of vegetation 1, the main control structure of the rock slope 15 is prone to geological disasters such as collapse, landslide, rockfall, or rockfall due to factors such as topography, meteorology, hydrology, and engineering excavation, which pose a serious threat to pedestrians and vehicles.

[0056] Therefore, refer to Figure 1 and Figure 5 This system also includes a sun protection module, which comprises:

[0057] A sun-protective curtain 12 is set above the coconut blanket 8;

[0058] The upper bracket 10 and lower bracket 11 of the sunshade curtain 12 are fixed. One side of the upper bracket 10 is fixed to the top of the drainage hole 7, and the other side extends horizontally away from the drainage hole 7. One side of the lower bracket 11 is fixed to the bottom of the coconut blanket 8, and the other side extends horizontally away from the coconut blanket 8.

[0059] In one embodiment of this example, an upper support 10 and a lower support 11 are respectively arranged on the upper and lower platform walkways of the rock slope 15. The supports are made of φ24 steel bars and the surface is uniformly sprayed with anti-corrosion material. A part of the support extends into the interior of the rock slope 15 to the main control structure surface. The length of the hanging section outside the slope surface is 20-40cm (the specific length is set according to the platform walkway of the rock slope 15). A cross-shaped frame is added to the two supports. The steel frame is made of stainless steel with a size of 30cm×40cm×50cm to enhance the overall stability and firmness of the sunshade curtain 12.

[0060] The sunscreen curtain 12 is made of polyester fiber material (polyester fiber material is a type of chemical fiber material. The fabric of this material has high strength and long life, and at the same time has good softness and plasticity). The curtain color is green to provide a visual effect.

[0061] The sunshade curtain 12, the coconut fiber blanket 8, and the small drainage pipe 9 are located on the same slope, together providing growing conditions for the climbing plants 16 on the rock slope 15. When the climbing plants 16 are planted and carried to the soil of the rock slope 15 by the wind or animals, they begin to take root and sprout on the surface of the rock slope 15.

[0062] The climbing plant 16 is fragile in its early stages. The sunshade curtain 12 blocks most of the strong light and reduces the surface temperature of the rock slope 15. At the same time, the small drainage pipes 9 can spray water in all directions on the slope surface to provide water for the climbing plant 16. Therefore, under mild weather and water conditions, the climbing plant 16 can grow well, greatly improving its early survival rate.

[0063] Furthermore, climbing holes 13 are provided on the upper support 10, and hanging holes 14 are provided on the lower support 11. When the climbing plants 16 enter their vigorous growth period, they are less affected by direct sunlight. The climbing plants 16 can propagate outward through the climbing holes 13 in the gaps of the upper support 10, and the climbing plants 16 can hang down through the hanging holes 14 in the gaps of the lower support 11.

[0064] Meanwhile, the upper climbing hole 13 and the lower hanging hole 14 can balance the air pressure inside and outside the sunshade curtain 12, preventing the sunshade curtain 12 from being blown away or damaged in severe weather such as strong winds. With sufficient root water, the climbing plant 16 grows rapidly and can continue to climb and hang along the surface of the sunshade curtain 12 until it covers the sunshade curtain 12.

[0065] At this point, the entire rock slope 15 is covered with green vegetation 1, greatly improving the local vegetation environment 1 and ecosystem.

[0066] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made to the above embodiments by those skilled in the art are within the protection scope of the present invention.
