[0001] The invention belongs to the technical field of ecological protection, and in particular relates to an ecological protection structure for soil and water conservation on a highway roadbed slope. Background Art

[0002] Roadbed slope refers to the slope with a certain slope built on both sides of the roadbed to ensure the stability of the roadbed. It can be divided into soil slope and rock slope according to the rock type of the slope. In order to ensure the overall stability of the slope and avoid slope instability caused by rain erosion, thereby causing disasters such as falling rocks, collapse, and mudslides, the slope needs to be protected. For soil slopes, water diversion and drainage structures are often built on the slope surface and then planting soil is laid to allow plants to grow, thereby playing a role in soil and water conservation and protection of the slope.

[0003] After the existing roadbed slopes are paved with vegetation soil, the root systems of the ecological plants are not well developed in the early stages of their growth, and the water-locking and soil-fixing effects are not significant. When the rainfall is heavy or the wind is strong, the ecological plants and planting soil are easily uprooted and the planting soil is lost under the action of rainwater erosion and wind, which greatly reduces the protective effect of the slope ecological protection structure on the slope.

[0019] like Figures 1 to 5 As shown, a highway roadbed slope soil and water conservation ecological protection structure of the present invention comprises a slope main body 1, a concrete enclosure 2 is arranged on the inclined surface of the slope main body 1, a planting area 3 for planting a plurality of ecological plants 15 is arranged on the concrete enclosure 2, the planting area 3 is connected with the inclined surface of the slope main body 1, a pipe network frame is arranged horizontally in the planting area 3, a plurality of U-shaped pins 10 are arranged on the pipe network frame, the plurality of U-shaped pins 10 fix the pipe network frame on the inclined surface of the slope main body 1, a plurality of evenly distributed conical springs 11 are arranged on the pipe network frame, the large diameter ends of the plurality of conical springs 11 are fixed on the pipe network frame, the plurality of conical springs 11 are each provided with an ecological plant 15 inside, the root system of the ecological plant 15 penetrates into the interior of the conical spring 11 from the small diameter end of the conical spring 11, the planting area 3 is filled with planting soil 16, the planting soil 16 fills the interior of the conical spring 11, and the conical spring 11 is entirely buried in the interior of the planting soil 16.

[0020] The working principle of the above technical solution is: After the construction of the concrete enclosure 2 is completed and the slope body 1 is anti-slip reinforced, the pipe network frame is fixed to the slope body 1 by the U-shaped pin 10, and then the roots of the ecological plants 15 are placed inside the conical springs 11. The roots of the ecological plants 15 are fixed and covered by filling the conical springs 11 with planting soil 16. After the ecological plants 15 are planted inside several conical springs 11, the cavity part in the planting area 3 is filled by covering it with concrete, thereby completing the construction of the ecological protection structure.

[0021] The advantage of the above scheme is that, firstly, the small diameter end of the conical spring 11 is arranged outward, that is, the plant root system covering the planting soil 16 is arranged in a conical shape, that is, the conical planting soil 16 will be blocked and restricted by the small diameter end of the conical spring 11, that is, the planting soil 16 inside the conical spring 11 will not be displaced, and then the root system of the ecological plant 15 inside it cannot be easily separated from the planting soil 16 under the squeezing of the planting soil 16, thereby ensuring the stability of the plant root system in the early stage of planting, and improving the wind resistance and The effect of resisting rain erosion; secondly, after the roots of the ecological plant 15 grow, the roots will pass through the inside of the conical spring 11 to the outside of the conical spring 11, and then be wrapped around the conical spring 11. Since the conical spring 11 is fixed in the planting area 3, the roots of the ecological plant 15 are wrapped around it, which further improves the stability of the roots of the ecological plant 15, further improves the wind resistance and anti-erosion effect of the ecological plant 15, and ensures the planting, growth and retention effect of the ecological plant 15 in the planting area 3.

[0022] At the same time, the setting of the concrete enclosure 2 can block the planting soil 16 in the planting area 3 to prevent the loss of the planting soil 16 therein. At the same time, the mutual combination of the planting soil 16 and the pipe network frame can also enhance the bonding ability of the planting soil 16 in the planting area 3, further ensuring the retention effect of the planting soil 16 in the planting area 3.

[0023] In one practicable manner, the pipe network frame arranged in the planting area 3 includes several main water inlet pipes 7 arranged horizontally, and one end of the several main water inlet pipes 7 is provided with a connecting pipe 8, which is connected to the ends of the several main water inlet pipes 7. The ends of the several main water inlet pipes 7 located in the middle that are not provided with the connecting pipe 8 are closed, the interior of the conical spring 11 is hollow, and one end of the conical spring 11 is connected to the interior of the pipe network frame, the other end of the conical spring 11 is closed, and a plurality of seepage holes 12 are provided on the inward side of the conical spring 11, and the plurality of seepage holes 12 are evenly distributed on the surface of the conical spring 11.

[0024] In the early stage of planting or during drought, high-pressure water can be injected into the main water inlet pipe 7 to transport water to the inside of the conical spring 11. The water is discharged from the infiltration holes on the inner side of the conical spring 11 and directly acts on the root system of the ecological plant 15, thereby ensuring the water absorption effect of the ecological plant 15 and improving the maintenance effect of the ecological plant 15. At the same time, this method does not need to water all the planting soil 16 in the planting area 3, and can achieve fixed-point watering of the root system of the ecological plant 15, which can save water resources to a certain extent.

[0025] In one feasible manner, a plurality of connecting branch pipes 9 are provided between a plurality of main water inlet pipes 7. The plurality of connecting branch pipes 9 are distributed in a network pattern and connect a plurality of main water inlet pipes 7. The provision of the connecting branch pipes 9 enables the supplied water to flow from multiple directions, thereby avoiding partial blockage of the main water supply pipe 13, resulting in the problem that the rear section of the blocked part cannot supply water.

[0026] In one feasible manner, a drainage ditch 5 is provided on the slope main body 1 on one side of the planting area 3, and a water collecting ditch 4 is provided on the slope main body 1 at the upper end of the drainage ditch 5. The drainage ditch 5 and the water collecting ditch 4 are connected, and a water supply pipe 13 is provided in the drainage ditch 5. The water supply pipe 13 is arranged parallel to the length direction of the drainage ditch 5, and the unclosed ends of the two main water inlet pipes 7 located on the outermost side are extended to the drainage ditch 5 and connected with the water supply pipe 13. The drainage ditch 5 is arranged on the slope main body 1 to divert rainwater at one end to prevent rainwater from directly eroding the planting soil 16. At the same time, the water supply pipe 13 is arranged, and the end of the water supply pipe 13 is arranged in the water collecting ditch 4. The main water inlet pipes 7 in several planting areas 3 in the length direction of the drainage ditch 5 can be supplied with water by supplying water to the end of the water supply pipe 13. There is no need to supply water to multiple planting areas 3 separately, thereby improving maintenance efficiency.

[0027] In one feasible manner, a water trough 6 is provided on the slope body 1, the upper end of the water trough 6 is connected to the water collecting ditch 4, a water pump 14 is provided inside the water trough 6, one end of the water supply pipe 13 extends into the water trough 6 and is connected to the output end of the water pump 14. The setting of the water trough 6 can collect rainwater when it rains to achieve the purpose of water storage. When it is necessary to water the ecological plants 15, the rainwater in the water trough 6 can be directly transported to the planting area 3 by controlling the water pump 14 to pump water. Of course, the number and size of the water troughs 6 can be set according to actual conditions. Of course, if construction conditions permit, the end of the water supply pipe 13 can also be connected to the municipal pipeline network to achieve water supply on demand.

[0028] In one practicable manner, a filter net is provided at the portion where the water tank 6 communicates with the water collecting ditch 4 to prevent debris in the water collecting ditch 4 from entering the water tank 6 and causing the water pump 14 to be blocked.

[0029] In one feasible manner, an arc-shaped guide groove is provided on the bottom surface of the water collecting ditch 4 near the water trough 6. The arc-shaped guide groove guides the water in the water collecting ditch 4 to the water trough 6. When the rainfall is small, the rainwater can be preferentially guided into the water trough 6 for collection through the arc-shaped guide groove. When the water trough 6 is full of water and overflows, it is discharged through the drainage ditch 5, which can improve the efficiency of rainwater collection.

[0030] In one feasible manner, the conical spring 11 has a large stiffness and a small deformation under the squeezing action in the planting soil 16. It can be understood that the conical spring 11 is not easily compressed and stretched. In some places where the soil is relatively loose, when water is supplied, under the action of water pressure, the conical spring 11 is not easily deformed, and will not cause pulling and prying on the roots and soil of the plant, further ensuring the planting effect of the ecological plants 15; of course, in another embodiment, the conical spring 11 has a small stiffness and is easy to deform. The advantage of this method is that it can be used in places where drought or soil is easily compacted, that is, each water supply will pry the compacted soil, making the compacted soil fluffy, so that the plant roots can better contact and grow with water. It can be selected and used according to actual conditions.

[0031] In an practicable manner, a plurality of evenly distributed water seepage holes 12 are also provided on the outer side surface of the conical spring 11, so as to further improve the water supply area around the root system of the ecological plant 15 and enhance the water supply effect.

[0032] In one feasible manner, the inner wall of the water tank 6 is paved with a waterproof cloth, so that the collected rainwater is not easily infiltrated and discharged from the soil, thereby ensuring the water storage effect of the water tank 6.

[0033] It should be noted that, since the various components in the present technical solution are buried under the planting soil 16, they all need to be made of anti-corrosion materials, such as PVC, and no further elaboration is given here.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
