Description

Technical Field

[0001] This invention relates to the field of slope ecological restoration technology, and in particular to a slope ecological restoration system and method based on lattice beams. Background Technology

[0002] The lattice beam slope ecological restoration technology is an important technical means in the current intersection of geotechnical engineering and environmental engineering. It aims to stabilize the slope through engineering structure and realize ecological functions in combination with vegetation restoration.

[0003] Currently, transverse lattice beams are only regarded as pure slope reinforcement components, and their huge potential as a natural load-bearing platform is completely ignored. In order to achieve rapid greening, engineering practice generally adopts methods such as fixing geocells in the frame, stacking ecological bags, or spraying topsoil to force full slope soil coverage, with an average thickness of more than 10cm.

[0004] This conventional approach has led to numerous irreconcilable conflicts. First, the transverse lattice beams significantly block natural rainfall and artificial sprinkler irrigation. Coupled with rapid runoff loss from the slope, the soil moisture content in the critical 30-40cm area directly below the beams remains below the plant survival threshold, forming stubborn strip-shaped areas of bare degradation and ultimately resulting in severely uneven vegetation cover on the slope. Second, covering the entire slope with soil provides a breeding ground for weeds. With their strong competitive advantage, weeds quickly suppress target plants in terms of water, nutrients, and light, resulting in poor vegetation restoration and difficulty in forming a stable landscape. Manual weeding is inefficient and poses significant safety hazards on steep slopes, while chemical weeding carries risks of inaccurate control, environmental pollution, and damage to target plants, thus contradicting the original intention of ecological restoration.

[0005] Therefore, developing a new ecological restoration system and method that can overcome the above-mentioned defects has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a slope ecological restoration system and method based on lattice beams.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: Design a slope ecological restoration system based on lattice beams, including lattice beams formed on the slope surface, wherein the lattice beams divide the slope into multiple planting grids; A planting trough is installed above the crossbeam of the lattice beam, and the bottom of the planting trough is inserted into the planting grid along the crossbeam; The planting trough has a planting cavity inside, and the planting trough is equipped with a water-guiding structure that conforms to the slope of the planting grid.

[0008] Furthermore, the planting trough includes; The bottom surface, the side elevations perpendicularly connected to the two sides of the bottom surface, and the front elevation perpendicularly connected to the bottom surface; The front facade connects between the two side facades, and the bottom, side facades, and front facade together form the implantation cavity.

[0009] Furthermore, mounting holes are provided on the end faces of both the bottom surface and the side elevation, and the mounting holes are fixedly connected to the lattice beams by fasteners; At least a portion of the bottom surface is inserted into the interior of the planting grid, and the height baseline of the front facade and the slope is parallel.

[0010] Furthermore, the water-guiding structure includes; A support plate, an arc-shaped plate, and a baffle are fixed between the two side facades, with the baffle connected to the rear of the support plate and the arc-shaped plate; The middle part of the arc-shaped plate protrudes upward toward the planting trough, the support plate is located below the arc-shaped plate, and a support plate supporting the lower side of the arc-shaped plate is fixedly installed in the middle of the support plate, wherein the arc-shaped plate is attached to the front side of the slope of the planting grid.

[0011] Furthermore, drip holes are provided on the end faces of both the support plate and the arc-shaped plate, and drainage holes are also provided on the end face of the side facade, with the drainage holes located on the upper side of the arc-shaped plate.

[0012] Furthermore, the interior of the planting cavity is filled with a planting substrate layer, which is attached to the slope of the planting grid; A plurality of drainage holes are provided on the end face of the bottom surface, and a filler is provided between the planting substrate layer and the drainage holes.

[0013] Furthermore, a barrier sheet is fixed above the bottom surface, and the filler is located on the side of the barrier sheet; The barrier sheet has a root guide structure on its side away from the filler.

[0014] Furthermore, the rhizome guiding structure includes; Multiple cone-shaped bodies are fixedly installed on the end face of the barrier sheet; The cone-shaped body has a hollow structure with an open end. An air-proof hole is provided on the upper side of the cone-shaped body. A cotton strip is filled in the hollow structure. One end of the cotton strip extends to the front end of the cone-shaped body, and its outer side covers the area below the air-proof hole.

[0015] Furthermore, the bottom surface, side facades, and front facade are all made of stainless steel, and a water-retaining layer is bonded to the inner side of the side facades and front facades.

[0016] In addition, this invention also proposes a slope ecological restoration method based on lattice beams, which uses the above-mentioned system. Specifically, the method includes the following steps; Based on the ecological restoration schedule, the planting troughs are processed and installed before the weeds seed or after the seeds fall. When installing the planting trough, the bottom and sides are placed between the slope soil and the grid beam, and the slope soil is wrapped in the planting trough until the water guiding structure comes into contact with the slope soil. Fill the planting cavity of the planting trough with a layer of planting substrate, with the substrate surface 20mm below the trough opening, and sow plants with a drooping effect. Based on the actual situation, perform routine management such as weeding, fertilizing, spraying pesticides, and watering on the plants in the planting trough; As the plants grow well, the drooping branches can extend to the top of the next planting grid, forming a plant community with the native plants in the next planting grid, ultimately achieving a stable natural state and a good landscape effect.

[0017] The present invention proposes a slope ecological restoration system and method based on lattice beams, the beneficial effects of which are: In this invention, by installing a planting trough on the crossbeam of each planting grid, the crossbeam can be transformed from a shielding component into a stable planting platform, thus effectively increasing the vegetation coverage of the slope. In addition, the planting trough integrates a water-guiding structure, which can accurately capture slope runoff and directionally replenish the plants in the trough. After the plants in the planting trough hang down, they can extend to the upper part of the next planting grid along with the plants in the planting grid below, forming a plant community with the native plants on the upper part of the planting grid. This not only stabilizes and protects the soil and water above the planting grid, but also creates a good landscape effect. Meanwhile, the plants in the planting troughs will coexist with the plants in the planting grids above the beams, creating "ecological anchor points" to suppress weeds and forming a stable community structure. Through the self-organized succession of the native plant community, the amount of weeds is effectively reduced, completely eliminating the need for later maintenance. This effectively solves the industry's chronic problems such as water imbalance, uncontrolled weeds, poor slope vegetation stability, and poor landscape effect on grid beam slopes. In this way, engineering measures (grid beams) and ecological measures can be integrated, playing an important supporting role in slope stability protection and ecological landscape construction.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-9 As an embodiment of the present invention, a slope ecological restoration system based on lattice beams is disclosed. This restoration system is used to solve the industry problems of water imbalance, uncontrolled weeds, poor slope vegetation stability and poor landscape effect of lattice beam slopes. Specifically, the repair system includes a grid beam 2 formed on the slope 1, which divides the slope 1 into multiple planting grids 10. Of course, the grid beam 2 is made of steel cage and concrete. Drainage channels can also be set on the longitudinal beams of the grid beam 2 to realize slope drainage. The specific setting method is a conventional design method for those skilled in the art, and will not be elaborated here. A planting trough 3 is installed above the crossbeam 20 of the lattice beam 2, and the bottom of the planting trough 3 is inserted into the planting grid 10 along the crossbeam 20; The planting trough 3 has a planting cavity 30 inside, and a water guiding structure 4 that conforms to the slope of the planting grid 10 is provided inside the planting trough 3. The water guiding structure 4 is used to quickly drain the rainwater that enters the planting trough 3, so as to achieve controllable water in the planting trough 3, complete retention of substrate, and prevent the substrate from overflowing the planting trough 3 due to short-term excessive water, thus providing a longer effective space for plant root growth.

[0022] In other words, by installing a planting trough 3 on the crossbeam 20 of each planting grid 10, the crossbeam 20 can be transformed from a shielding component into a stable planting platform, thus effectively increasing the vegetation coverage of the slope 1. In addition, the planting trough 3 integrates a water guiding structure 4, which can accurately capture slope runoff and directionally replenish the plants in the trough. After the plants in the planting trough 3 hang down, they can extend to the upper part of the next planting grid 10 together with the plants in the planting grid 10 below, and form a plant community with the native plants on the upper part of the planting grid 10. This not only stabilizes and protects the soil and water above the planting grid 10, but also creates a good landscape effect.

[0023] In some embodiments, the planting trough 3 of the present invention includes; The bottom surface 31, the side elevations 32 perpendicularly connected to the two sides of the bottom surface 31, and the front elevation 33 perpendicularly connected to the bottom surface 31; The front elevation 33 is connected between the two side elevations 32, and the implantation cavity 30 is formed between the bottom surface 31, the side elevations 32 and the front elevation 33.

[0024] Specifically, the bottom surface 31, side surface 32, and front surface 33 of this invention are all made of stainless steel. The soil surface near the slope 1 and the top surface are empty surfaces. The size of the bottom surface 31 in this embodiment can be customized according to the actual width of the grid beam and the soil layer. For example, in an optional embodiment, the size of the bottom surface 31 of this invention can be set to 1500mm*400mm.

[0025] Furthermore, the bottom surface 31 is located between the top surface of the beam 20 and the soil, serving to support the planting soil and transfer the weight of the substrate in the planting trough 3 to the beam 20 of the cement grid beam.

[0026] Of course, in order to facilitate the installation of the entire planting trough 3, mounting holes 34 are provided on the end faces of the bottom surface 31 and the side surface 32 in this invention. The mounting holes 34 are fixedly connected to the lattice beam 2 by fasteners. At least a portion of the bottom surface 31 is inserted into the interior of the planting grid 10, and the height baseline of the front surface 33 and the slope 1 are parallel.

[0027] Specifically, the fasteners described in this invention can be expansion bolts. In this embodiment, four mounting holes 34 are distributed in a matrix on the end face of the side facade 32, and three mounting holes 34 are provided on the end face of the bottom surface 31. During installation, the prefabricated planting trough 3 is inserted into the slope soil along the upper side of the crossbeam 20 of the lattice beam 2 until the top water guiding structure 4 contacts the soil, and the planting trough 3 is fixed with expansion bolts. This creates a plant growth space that retains water and fertilizer, is easy to manage, and is integrated with the slope.

[0028] Based on the above embodiments, the water-guiding structure 4 in this invention includes; A support plate 41, an arc plate 42, and a baffle 43 are fixed between the two side facades 32. The baffle 43 is connected to the rear of the support plate 41 and the arc plate 42. The baffle 43 and the arc plate 42 have an L-shaped structure. The middle part of the arc-shaped plate 42 protrudes upward toward the planting trough 3. The support plate 41 is located below the arc-shaped plate 42. A support plate 44 supporting the lower side of the arc-shaped plate 42 is fixedly installed in the middle part of the support plate 41. The arc-shaped plate 42 is attached to the front side of the slope of the planting grid 10.

[0029] Specifically, the support plate 41 described in this invention is used to enhance the stability of the arc plate 42. Of course, the support plate 44 is also used to reinforce the arc surface of the arc plate 42. Optionally, the support plate 41, the arc plate 42 and the baffle 43 described in this invention are also made of stainless steel.

[0030] During installation, the bottom of the support plate 41 must be in contact with the slope soil. When the slope runoff flows downward, it is intercepted by the curved plate 42. The curvature can quickly guide the water flow to both sides, thereby achieving controllable water in the planting trough and complete retention of the substrate. The substrate will not overflow the planting trough 3 due to short-term excessive water, providing a longer effective space for plant root growth.

[0031] In this invention, the use of an arc-shaped plate 42, which is designed to be high in the middle and low on both sides, with its opening facing the soil surface to intercept slope runoff and guide it to both sides of the grid beam, leaves the top surface of the planting trough 3 empty for planting plants, thus enhancing the landscape effect of the slope. The remaining side is empty, allowing the planting substrate to connect with the slope soil. This means that the plant roots are not limited to growing in the planting trough 3, but can also grow towards the slope soil.

[0032] In some embodiments, drip holes 45 are provided on the end faces of the support plate 41 and the arc plate 42 in this invention, and drainage holes 35 are also provided on the end face of the side facade 32. The drainage holes 35 are located on the upper side of the arc plate 42. Specifically, 16 drip holes 45 with a diameter of 10 mm can be provided on the end faces of the support plate 41 and the arc plate 42 in this invention. The drip holes 45 are used to leak water to replenish a certain amount of water to the planting trough 3. The intercepted water can drip into the planting trough 3 in an appropriate amount, increasing the water content in the planting trough 3 and increasing the soil moisture content of the slope surface connected to the planting trough 3, which is conducive to the growth of plant roots towards the slope. The drainage hole 35 is used to quickly discharge water from the arc plate 42. In this embodiment, the lower edge of the drainage hole 35 is in contact with the upper edge of the arc plate 42.

[0033] In some embodiments, the planting cavity 30 of the present invention is filled with a planting substrate layer 36, which is attached to the slope of the planting grid 10. A plurality of drainage holes 37 are provided on the end face of the bottom surface 31, and a filler 38 is provided between the planting substrate layer 36 and the drainage holes 37.

[0034] Preferably, the filler 38 in this embodiment of the invention can be made of non-woven fabric, gauze, ceramsite, or cinder, etc., to reduce the loss of planting substrate 36 and further solve the problem of substrate clogging the drainage holes 37. Specifically, the drainage holes 37 in this invention are designed to drain water in the trough in a timely manner, avoid water accumulation in the planting trough causing root rot of plants, and effectively prevent water accumulation from having an adverse effect on plant growth. Optionally, the drainage holes 37 in this invention can be designed to be distributed in two rows, with a diameter of 10-20 mm and a hole spacing of 200 mm. Of course, the water drained through the drainage holes 37 can also flow slowly downwards and eventually penetrate into the upper part of the next planting grid 10, thereby nourishing the plants in the planting grid 10 below.

[0035] Optionally, the planting substrate layer 36 described in this embodiment of the invention can be specially formulated according to different plants, such as commonly used garden soil: peat soil: chicken manure organic fertilizer = 5:3:2.

[0036] In a further embodiment, a barrier sheet 39 is also fixed above the bottom surface 31 of the present invention, and the filler 38 is located on the side of the barrier sheet 39. The barrier plate 39 has a root guide structure 5 on its side away from the filler 38. Specifically, the barrier plate 39 designed in this invention is to stop the filler 38 to prevent the filler 38 from shifting position during the filling of the substrate. In addition, the root guide structure 5 in this invention is used to guide the growth of the plants in the planting trough 3, so that they can grow stably towards the soil of the planting grid 10 to form a soil-stabilizing complex.

[0037] Based on the above embodiments, the rootstock guiding structure 5 in this embodiment of the invention includes; Multiple conical bodies 51 are fixedly installed on the end face of the barrier plate 39; The cone-shaped body 51 has a hollow structure with an open end. An air-proof hole 52 is provided on the upper side of the cone-shaped body 51. A cotton strip 53 is filled in the hollow structure. One end of the cotton strip 53 extends to the front end of the cone-shaped body 51, and its outer side covers the bottom of the air-proof hole 52.

[0038] In other words, by adopting the design of the cone-shaped body 51 in this invention, when the planting trough 3 is inserted into the soil of the planting grid 10, the cone-shaped body 51 will also be inserted into the planting grid 10. The structural design of the cone-shaped body 51 is to facilitate its overall insertion. When the cone-shaped body 51 is inserted into the planting grid 10, the design of the cotton strip 53 will generate a water absorption effect, that is, the water at the bottom of the planting grid 10 will be stably transferred to the air-proof hole 52. The air-proof hole 52 of the present invention faces the top of the planting trough 3. Since plants have the characteristic of liking water, when the plants are planted in the planting trough 3, their roots will grow towards the side of the cone-shaped body 51. In this way, they slowly extend and take root into the soil of the planting grid 10, thus forming a soil-stabilizing complex of substrate and plants in the planting trough 3 and soil and plants in the planting grid 10, and forming a plant community. Natural recovery is achieved by the seed diffusion and root expansion of the mature plants in the trough, or by the natural growth and succession of the slope plants, so that artificially planted plants and native plants coexist, constructing an "ecological anchor" to suppress weeds and forming a stable community structure.

[0039] It should be noted that, in this embodiment of the invention, a water-retaining layer is bonded to the inner side of both the side facade 32 and the front facade 33. Optionally, the water-retaining layer in this invention can be set as a non-woven fabric, sponge, or water-retaining coating layer, which is used to reduce water loss and ensure the stability of plant growth in the planting trough 3.

[0040] In addition, this invention also proposes a slope ecological restoration method based on lattice beams, which uses the above-mentioned system. Specifically, the method includes the following steps; S1. Based on the ecological restoration schedule, the planting trough 3 is processed and installed before the weeds seed or after the seeds fall. S2. When installing the planting trough 3, the bottom and sides are placed between the slope soil and the grid beam 2, and the slope soil is wrapped in the planting trough 3 until the water guiding structure 4 comes into contact with the slope soil. S3. Fill the planting cavity 30 of the planting trough 3 with the planting substrate layer 36, the substrate surface is 20mm lower than the opening of the trough, and sow plants with a drooping effect. The substrate can be a general type (garden soil: peat moss: bio-organic fertilizer = 5:3:2), or the types and proportions of substrate can be increased or decreased according to the soil conditions and plant needs. The evenly mixed substrate is filled into planting trough 3. Plants such as bougainvillea, winter jasmine, creeping magnolia, and Rangoon creeper can be selected to form a hanging plant structure. The planting density is determined reasonably according to the seedling specifications, and the plants are planted in a triangular pattern to ensure that the branches grow orderly and droop outwards. By selecting drooping plants, they can provide shade and protection to the upper part of the lower planting grid 10 after they grow, thus reducing water runoff caused by sunlight. At the same time, these plants will form a plant community with the plants in the lower planting grid 10, thereby achieving the protection of soil and water on the upper part of the lower planting grid 10.

[0041] S4. Based on the actual situation, perform routine management such as weeding, fertilizing, spraying pesticides, and watering on the plants in the planting trough 3. Of course, in other embodiments, automatic sprinkler irrigation and integrated water and fertilizer systems can also be combined to reduce labor costs. S5. As the plants grow well, the drooping branches can extend to the upper part of the next planting grid 10, forming a plant community with the native plants in the next planting grid 10, ultimately achieving a stable natural state and a good landscape effect.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
