Description

Technical Field

[0001] The invention relates to the technical field of slope vegetation systems, and in particular to a slope vegetation system and a construction method thereof. Background Art

[0002] Slope vegetation system refers to the vegetation coverage system established on the surface of natural or artificial slopes. It is mainly composed of plant individuals, plant communities, and environmental elements such as soil and microorganisms that interact with them. Its purpose is to utilize the ecological functions of vegetation, such as maintaining water and soil, stabilizing slopes, and beautifying the environment.

[0003] The traditional method of vegetation protection is to directly sow grass seeds or plant simple herbaceous plants on the slope. However, this method faces many problems. The soil on the slope is usually poor and has poor water and fertilizer retention capacity. The conditions required for seed germination and plant growth are difficult to meet. In areas with heavy rainfall, the slope is easily washed away by rainwater, and newly sown or planted vegetation is easily washed away, making it difficult to increase the vegetation coverage rate. Moreover, in the long run, the root system of a single herbaceous vegetation protection has limited effect on the reinforcement of the slope soil. For some slopes with large slopes or poor soil quality, there is still the risk of geological disasters such as landslides. At the same time, traditional vegetation protection lacks effective regulation of slope moisture and nutrients, and it is difficult to adapt to complex and changing climate conditions. Summary of the invention

[0004] To overcome the deficiencies of the prior art, the present invention provides a slope vegetation system and a construction method, which solves the technical problems that plants are difficult to grow on slopes with poor soil and the slope vegetation coverage rate is difficult to increase.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: The slope vegetation system includes: a slope body, a regulating pipeline component, and a water collection ditch. The slope body is provided with: a protective layer, a planting layer, and a vegetation layer from the inside to the outside. The regulating pipeline component is buried in the protective layer. The regulating pipeline component is used to remove moisture or transport water and nutrients. The water collection ditch is arranged at the bottom of the slope body. The water collection ditch is connected to the regulating pipeline component. The planting layer includes a bidirectional permeable material. The planting layer is used to remove or transport moisture to the vegetation layer.

[0006] Based on the above structure, the principle of the slope vegetation system is as follows: the protective layer is located between the slope and the planting layer, which can effectively prevent the slope from being directly eroded by external factors. The protective layer works closely with the planting layer and the vegetation layer to jointly enhance the stability of the slope surface; the regulating pipe assembly buried in the protective layer is used to remove moisture or transport water and nutrients. The protective layer provides a stable installation environment for the regulating pipe assembly to ensure that the regulating pipe assembly can function normally. When it rains, the protective layer can guide rainwater to flow into the regulating pipe assembly. Since the ditch is connected to the regulating pipe assembly, excess water can be discharged from the slope in time and stored in the ditch. In addition to the drainage function, the regulating pipe assembly can also transport nutrients in the protective layer. When nutrients need to be transported, the nutrients are first released into the ditch, and then the water is used. The pump draws the nutrient-containing rainwater from the ditch into the regulating pipe assembly and transports it to different locations on the slope. The planting layer uses bidirectional permeable materials. When there is too much water in the planting layer, the pores in the bidirectional permeable materials quickly take effect. Under the guidance of gravity and the pores of the bidirectional permeable materials, the water penetrates toward the slope. This drainage mechanism can effectively avoid water accumulation in the planting layer and prevent the roots of vegetation from rotting due to long-term immersion in water. It also reduces the risk of geological disasters such as landslides caused by excessive water accumulation on the slope. In drought conditions, the bidirectional permeable materials demonstrate their ability to infiltrate water. The water stored in the bidirectional permeable materials will slowly penetrate from the materials to the vegetation layer under the action of the soil moisture gradient, providing the roots of vegetation with the necessary water and nutrients to ensure the stability of the slope vegetation system of the entire slope.

[0007] Furthermore, in the slope vegetation system of the present application, the bidirectional permeable material is one of ceramsite, vermiculite, coconut bran, and artificially synthesized sponge-like polymer materials. As a preferred embodiment of the present application, the slope vegetation system of the present invention has a large number of pores inside the bidirectional permeable material, which can absorb a large amount of water and store water. When the water content in the planting layer is oversaturated, the water in the planting layer will seep into the protective layer under the action of the bidirectional permeable material to reduce the water content in the planting layer and prevent the roots of the vegetation from rotting due to long-term immersion in water; when the water content in the planting layer is insufficient, the bidirectional permeable material can release the water stored in its internal pores to provide the necessary water and nutrient supply for the roots of the vegetation, thereby ensuring the stability of the slope vegetation system of the entire slope.

[0008] Furthermore, in the slope vegetation system of the present application, the regulating pipeline assembly includes: a group of transverse pipes, a group of the transverse pipes are evenly spaced along the inclination direction of the slope, a group of longitudinal pipes are arranged between two adjacent pairs of transverse pipes, a group of longitudinal pipes are evenly spaced along the extension direction of the transverse pipes, and the two ends of the longitudinal pipes are respectively connected to the two adjacent transverse pipes, and the outer walls of the transverse pipes and longitudinal pipes are provided with through holes, and the through holes are used to collect rainwater in the protective layer or transport water and nutrients. As a preferred embodiment of the present application, in the slope vegetation system of the present invention, a group of transverse pipes cooperate with the longitudinal pipes, and when it rains, when rainwater infiltrates into the protective layer, the rainwater will enter the regulating pipeline assembly through the through holes provided on the transverse pipes and longitudinal pipes. Since the water collection ditch is connected to the regulating pipeline assembly, the rainwater will eventually enter the water collection ditch, complete the collection of rainwater, and prevent the protective layer from being eroded by rainwater, thereby improving the stability of the protective layer; when the vegetation layer needs water and nutrients, the regulating pipeline assembly serves as a transport channel, and transports the nutrient solution to different positions on the slope through the through holes.

[0009] Furthermore, in the slope vegetation system of the present application, the outer sides of the transverse pipe and the longitudinal pipe are provided with a filter layer, and the filter layer is covered on the outer side of the through hole. As a preferred embodiment of the present application, in the slope vegetation system of the present invention, the filter layer is used to intercept soil particles in the protective layer, prevent the soil structure in the protective layer from being damaged, ensure the integrity of the soil structure, prevent soil particles in the protective layer from entering the control pipeline assembly, prevent the blockage of the transverse pipe and the longitudinal pipe, and extend the service life of the transverse pipe and the longitudinal pipe.

[0010] Furthermore, the slope vegetation system in the present application, the vegetation layer includes: a first vegetation area, a second planting area, and a third planting area, and the first vegetation area, the second planting area, and the third planting area are arranged in sequence along the bottom of the slope toward the foot of the slope. As a preferred embodiment of the present application, the slope vegetation system of the present invention adopts a multi-layered vegetation planting structure for the vegetation layer, and carries out layered planting according to the growth characteristics and ecological niches of different plants. The first vegetation area is planted with trees with developed root systems, drought and waterlogging resistance, to provide a stable support for the slope surface; the second planting area is planted with shrubs to enhance the erosion resistance of the slope surface; the third planting area is planted with herbaceous plants to play a role in rapid coverage and soil and water conservation; this three-dimensional layered structure can make full use of space and improve the ecological protection effect of the slope vegetation system.

[0011] Furthermore, the slope vegetation system in the present application also includes: a group of slope platform components, a group of the slope platform components are arranged on the slope body, a group of the slope platform components are respectively located between the first vegetation area, the second planting area and between the second planting area and the third planting area, the slope platform components include: a slope platform, a group of anchor rods, the slope platform is arranged at the upper end of a group of anchor rods, a group of the anchor rods are evenly spaced along the extension direction of the slope platform, and a group of the anchor rods all extend axially into the slope body. As a preferred embodiment of the present application, in the slope vegetation system of the present invention, the slope platform components are used to change the path and speed of slope runoff. When rainwater forms runoff on the slope, a group of slope platform components can play a role of blocking and buffering, slowing down the runoff speed, thereby reducing the possibility of slope soil being washed away, and effectively preventing soil erosion; a group of anchor rods are used to firmly anchor the slope platform on the slope body to ensure the stability of the slope platform.

[0012] The method for constructing a slope vegetation system comprises the following steps: S1, first level the slope surface, remove loose stones, debris and inorganic waste on the slope surface, and ensure that the slope surface is clean. S2, then install the control pipeline assembly on the slope according to the preset position, backfill the soil and compact it to the preset compaction degree to form a protective layer, S3, then the bidirectional permeable material is mixed evenly with the soil to be filled, and backfilled to a preset height to form a planting layer. S4, then a group of anchor rods are injected according to the preset spacing, and the slope platform is connected to the group of anchor rods. S5, then construct the water collection ditch according to the preset position, and connect the water collection ditch with the control pipeline assembly, S6, according to the division of the slope terraces, trees, shrubs and herbaceous plants are planted in the first vegetation zone, the second planting zone and the third planting zone from the bottom to the top of the slope to obtain a slope vegetation system.

[0013] The step S2 specifically comprises: according to the slope inclination direction of the slope, the horizontal pipe and the vertical pipe are sequentially installed and temporarily positioned on the slope, with the through holes facing upward; then the filter layer is covered on the outside of the through holes and fixed; then the soil material to be filled is backfilled to a preset elevation and compacted according to a preset compaction degree to form a protective layer.

[0014] It can be seen from the above technical solution that the present invention has the following beneficial effects: The present invention provides a slope vegetation system and a construction method. By constructing a multi-level vegetation planting structure in the vegetation layer, layered planting is performed according to the growth characteristics and ecological niches of different plants, thereby improving the ecological protection effect of the vegetation. The regulating pipe component buried in the protective layer can drain the water in time and guide it to the collection ditch when the moisture in the protective layer is too much, so as to ensure the water and soil stability of the protective layer. When the moisture in the protective layer is insufficient, the water stored in the collection ditch can be pumped out and recharged to different positions on the slope through the regulating pipe component. The planting layer adopts a bidirectional permeable material to enhance the water retention of the planting layer. When it rains, rainwater can smoothly pass through the bidirectional permeable material into the planting layer, thereby increasing the water content in the planting layer. In drought periods, the bidirectional permeable material can help store a certain amount of water, providing a continuous water supply for the vegetation, thereby ensuring that the withering of the vegetation due to lack of water is reduced, and improving the stability of the slope vegetation system.

DETAILED DESCRIPTION

[0017] like Figure 1 As shown, the slope vegetation system includes: a slope body 1, a regulating pipe component 5, and a drainage ditch 6. The slope body 1 is provided with: a protective layer 2, a planting layer 3, and a vegetation layer 4 from the inside to the outside. The regulating pipe component 5 is buried in the protective layer 2. The regulating pipe component 5 is used to remove moisture or transport water and nutrients. The drainage ditch 6 is arranged at the bottom of the slope body 1. The drainage ditch 6 is connected to the regulating pipe component 5. The planting layer 3 includes a bidirectional permeable material. The planting layer 3 is used to remove or transport moisture to the vegetation layer 4.

[0018] Based on the above structure, the principle of the slope vegetation system is as follows: the protective layer 2 is located between the slope 1 and the planting layer 3, which can effectively prevent the slope 1 from being directly eroded by external factors. The protective layer 2 cooperates closely with the planting layer 3 and the vegetation layer 4 to jointly enhance the stability of the slope 1; the regulating pipe assembly 5 buried in the protective layer 2 is used to remove moisture or transport water and nutrients. The protective layer 2 provides a stable installation environment for the regulating pipe assembly 5 to ensure that the regulating pipe assembly 5 can function normally. When it rains, the protective layer 2 can guide rainwater to flow into the regulating pipe assembly 5. Since the water collection ditch 6 is connected to the regulating pipe assembly 5, excess moisture can be discharged from the slope 1 in time and stored in the water collection ditch 6. In addition to the drainage function, the regulating pipe assembly 5 can also transport nutrients in the protective layer 2. When nutrients need to be transported, the nutrients are first released into the water collection ditch 6. A water pump (not shown) is then used to pump the nutrient-containing rainwater in the ditch 6 into the regulating pipe assembly 5 and transport it to different positions on the slope 1; the planting layer 3 adopts a bidirectional permeable material. When there is too much water in the planting layer 3, the pores in the bidirectional permeable material quickly take effect, and the water penetrates toward the slope 1 under the guidance of gravity and the pores of the bidirectional permeable material. This drainage mechanism can effectively avoid water accumulation in the planting layer 3 and prevent the roots of the vegetation from rotting due to long-term immersion in water. At the same time, it also reduces the risk of geological disasters such as landslides caused by excessive water accumulation on the slope; in drought conditions, the bidirectional permeable material demonstrates its ability to infiltrate water. The water stored in the bidirectional permeable material will slowly penetrate from the material to the vegetation layer 4 under the action of the soil moisture gradient, providing the necessary water and nutrient supply for the roots of the vegetation to ensure the stability of the slope vegetation system of the entire slope 1.

[0019] In this embodiment, the bidirectional permeable material is one of ceramsite, vermiculite, coconut bran, and artificially synthesized sponge-like polymer materials. There are a large number of pores inside the bidirectional permeable material, which can absorb a large amount of water and store water. When the water in the planting layer 3 is oversaturated, the water in the planting layer 3 will seep into the protective layer 2 under the action of the bidirectional permeable material to reduce the water content in the planting layer 3 and prevent the roots of the vegetation from rotting due to long-term immersion in water; when the water in the planting layer 3 is insufficient, the bidirectional permeable material can release the water stored in its internal pores to provide the necessary water and nutrient supply for the roots of the vegetation, thereby ensuring the stability of the slope vegetation system of the entire slope 1.

A group of transverse pipes 51 cooperates with the longitudinal pipes 52. When it rains, when rainwater infiltrates into the protective layer 2, the rainwater will enter the regulating pipe assembly 5 through the through holes 50 provided on the transverse pipes 51 and the longitudinal pipes 52. Since the water collecting ditch 6 is connected to the regulating pipe assembly 5, the rainwater will eventually enter the water collecting ditch 6, completing the collection of rainwater and preventing the protective layer 2 from being eroded by rainwater, thereby improving the stability of the protective layer 2. When the vegetation layer 4 needs water and nutrients, the regulating pipe assembly 5 serves as a conveying channel and conveys the nutrient solution to different positions on the slope 1 through the through holes 50.
