Description

Technical Field

[0001] This utility model relates to the field of ecological slope protection technology, and in particular to a landscape ecological slope protection structure for preventing soil erosion. Background Technology

[0002] Landscape ecological slope protection is a slope protection technology that integrates ecological protection, soil and water conservation, and landscape design. It combines planting (such as herbs, shrubs, and trees), engineering measures (such as laying ecological bricks, mesh, and gabions), and natural materials (such as wooden piles, pebbles, and humus) to construct a slope protection system with natural ecological functions and aesthetic value, while ensuring slope stability and safety. This slope protection method not only prevents soil erosion but also restores the biodiversity of the slope, creating a landscape effect that harmonizes with the surrounding environment, achieving multiple goals of "engineering safety + ecological restoration + landscape beautification."

[0003] A search revealed Chinese patent publication number CN214508556U, which discloses an environmentally friendly ecological slope protection system for landscaping. This system includes an installation shell, an installation structure, a filter structure, and an irrigation structure. The installation structure includes a reinforcing plate fixed to the side of the installation shell. A fixing wedge is fixed to the bottom of the reinforcing plate. A connecting block is fixed to one end of the installation shell, and a first protective plate is fixed to the top of the connecting block. A buffer column is fixed to one side of the first protective plate. This application utilizes a second protective plate and buffer springs to protect the ecological slope, reducing water damage and increasing its service life. A rainwater collection tank collects rainwater, which can be used to irrigate the plants on the ecological slope using a water pump and sprinkler heads, saving water resources. A cleaning brush cleans the first filter screen, facilitating the removal of filtered impurities from the collection tank and improving its overall cleanliness.

[0004] Regarding the aforementioned technologies, the inventors believe that the above patents mention beneficial effects such as: "The installation of ecological slope protection can be facilitated by structures such as reinforcing plates and fixing wedges; the first and second protective plates can protect the area near the water flow, preventing the water flow from carrying away the riverbank soil when it hits the riverbank; the second protective plate and buffer springs can protect the ecological slope protection, reducing the damage to the ecological slope protection by the water flow and increasing the service life of the ecological slope protection." However, during the use of ecological slope protection in landscape architecture, as the slope height increases during the construction of mountain roads, the cross-sectional dimensions of gravity retaining walls need to be continuously increased to maintain stability. This not only consumes a large amount of building materials and significantly increases construction costs, but also, on soft soil foundations, the excessively heavy walls can lead to foundation settlement, causing the walls to tilt, crack, or even collapse, creating safety hazards. Therefore, in order to address the above shortcomings, a landscape ecological slope protection structure for preventing soil erosion is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a landscape ecological slope protection structure to prevent soil erosion, aiming to improve the problem of some existing landscape ecological slope protection structures collapsing due to foundation settlement caused by increased slope height.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A landscape ecological slope protection structure for preventing soil erosion includes a trapezoidal slope. Multiple pebble layers are provided on the top side of the trapezoidal slope. A retaining wall is fixedly connected to the right end of the top side of the trapezoidal slope. Multiple drainage pipes are fixedly connected inside the trapezoidal slope. A water interception ditch is fixedly connected to the top of the left end of the trapezoidal slope. Multiple pressure balancing mechanisms are slidably connected to the top of the trapezoidal slope. Each pressure balancing mechanism includes a wall surface. The bottom ends of the multiple wall surfaces are slidably connected to the inside of the top of the trapezoidal slope. Reinforcing plates are fixedly connected to both sides of the wall surface. A pressing plate is slidably connected inside the wall surface. A reset component is slidably connected inside the pressing plate. A guide cylinder is fixedly connected to the bottom side of the reinforcing plate. Two transmission plates are fixedly connected to the bottom side of the guide cylinder via a disc. An extension plate is slidably connected to the bottom end of the transmission plate via a transmission column. An anchor rod is fixedly connected to the bottom side of the wall surface.

[0008] As a further description of the above technical solution:

[0009] The intercepting ditch includes an intercepting frame. The outside of the intercepting frame is fixedly connected to the inside of the left end of the trapezoidal slope. A stable support layer is fixedly connected to the bottom of the inner wall of the intercepting frame. A seepage-proof and soil-retaining layer is fixedly connected to the top side of the stable support layer. A water-passing section layer is fixedly connected to the top side of the seepage-proof and soil-retaining layer. An anti-erosion layer is fixedly connected to the top of the water-passing section layer. Multiple water outlets are opened on the bottom side of the intercepting frame.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes a guide post, the outside of which is slidably connected to the inside, and a spring is sleeved on the outside of the guide post;

[0012] As a further description of the above technical solution:

[0013] The top end of the spring is fixedly connected to the top side of the inner wall of the wall, and the bottom end of the spring is fixedly connected to the top side of the pressing plate.

[0014] As a further description of the above technical solution:

[0015] The top side of the guide post is fixedly connected to the top side of the inner wall of the wall, and the outside of the guide post is slidably connected to the inside of the guide cylinder.

[0016] As a further description of the above technical solution:

[0017] The two extension plates are slidably connected to the bottom left and right ends of the anchor rod, respectively, and the extension plates are slidably connected to the inside of the trapezoidal slope protection.

[0018] As a further description of the above technical solution:

[0019] The extension plate has an inclined opening inside, and the transmission column is slidably connected to the inside of the inclined opening.

[0020] As a further description of the above technical solution:

[0021] The material of the stabilizing support layer is cobblestone, the material of the seepage-proof and soil-retaining layer is crushed stone, the material of the water-passing section layer is sand and gravel, and the material of the erosion-proof layer is dry-laid stone.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, when the slope is subjected to external pressure, the wall transmits the pressure. Through a unique transmission structure, the extension plate slides to both sides and penetrates deeper into the slope, further enhancing the anchoring effect in conjunction with anchor rods, effectively dispersing and balancing the pressure. This allows it to actively adapt to changes in slope pressure, significantly improving the stability and durability of the slope protection structure. Whether dealing with soil expansion caused by rainwater soaking or pressure from other natural factors, this structure ensures long-term slope stability, reducing later maintenance costs and potential safety risks, and providing reliable safety protection for landscaped areas.

[0024] 2. In this invention, a pebble layer initially buffers rainwater erosion. The stabilizing support layer, impermeable soil-retaining layer, water-passing cross-section layer, and erosion-resistant layer of the intercepting ditch sequentially intercept, filter, and divert rainwater, effectively reducing soil loss from the slope. The drainage pipe promptly removes rainwater from the slope, preventing the soil from becoming soft due to prolonged waterlogging and maintaining the integrity of the slope's soil structure. This not only prevents soil erosion but also creates favorable soil conditions for plant growth on the slope, promoting vegetation restoration, enhancing ecosystem stability and biodiversity, and achieving an organic combination of ecological protection and landscape construction.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an ecological slope protection structure for preventing soil erosion in a garden landscape, comprising a trapezoidal slope protection 1, which serves as the basic framework of the entire ecological slope protection structure. Multiple pebble layers 2 are provided on the top side of the trapezoidal slope protection 1. These pebble layers 2 not only serve a decorative purpose, enhancing the natural beauty of the garden landscape, but also mitigate the direct erosion of the slope by rainwater to a certain extent, protecting the slope soil. A retaining wall 3 is fixedly connected to the right end of the top side of the trapezoidal slope protection 1. The retaining wall 3 is constructed of brick or concrete to hold back soil and prevent it from flowing out. Multiple drainage pipes 4 are fixedly connected inside the trapezoidal slope protection 1 to guide rainwater. A water interception ditch 5 is fixedly connected to the top of the left end of the trapezoidal slope protection 1. The water interception ditch 5 includes a water interception frame 51, the exterior of which is fixedly connected to the interior of the left end of the trapezoidal slope protection 1 by reinforced concrete pouring, forming a basic drainage channel structure.

[0035] The external connection of the intercepting frame 51 is fixedly connected to the inside of the left end of the trapezoidal slope 1. A stable support layer 52 is fixedly connected to the bottom of the inner wall of the intercepting frame 51. The stable support layer 52 is made of pebbles, which are uniform in size and hard in texture. Lay at the bottom of the intercepting frame 51, it provides stable support for the entire intercepting ditch 5, preventing the bottom of the ditch from collapsing due to water erosion, and also helps to disperse the impact force of the water flow. A seepage-proof soil-retaining layer 53 is fixedly connected to the top side of the stable support layer 52. The seepage-proof soil-retaining layer 53 is made of crushed stone. The pores between the crushed stone effectively filter rainwater, reducing soil particle loss with the water flow and playing a role in soil conservation. A water-passing cross-section layer 54 is fixedly connected to the top side of the seepage-proof soil-retaining layer 53. The water-passing cross-section layer 54 is made of sand and gravel. The sand and gravel particles are of moderate size, ensuring smooth water flow and forming a good water-passing cross-section, while also providing preliminary filtration of sediment in the water flow, reducing sediment deposition in the intercepting ditch 5. A scour-resistant layer 55 is fixedly connected to the top of the water-passing section layer 54. The scour-resistant layer 55 is made of dry-laid stone, which is cleverly stacked by hand to form a solid surface with a certain degree of roughness. This effectively slows down the water flow, reduces the scouring and erosion of the inner wall of the intercepting ditch 5, and extends the service life of the intercepting ditch 5. Multiple water outlets 56 are opened on the bottom side of the intercepting frame 51. Through the water outlets 56, rainwater is introduced into the interior of the diversion pipe 4.

[0036] Reference Figure 2 , Figure 3 and Figure 5The top of the trapezoidal slope protection 1 is slidably connected to multiple pressure balancing mechanisms 6, each of which includes a wall 61, which is formed by concrete pouring. The bottom ends of the multiple wall surfaces 61 are slidably connected to the inside of the top of the trapezoidal slope protection 1 by sliding the wall surface 61 into the interior of the trapezoidal slope protection 1 and then fixing it by pouring concrete. Reinforcing plates 62 are fixedly connected to both sides of the wall surface 61 by welding, thereby increasing the contact area between the reinforcing plates 62 and the surface of the trapezoidal slope protection 1. A pressing plate 63 is slidably connected inside the wall surface 61, allowing the pressing plate 63 to slide due to the constraint of the wall surface 61. A reset component 64 is slidably connected inside the pressing plate 63, providing a reset force for the pressing plate 63.

[0037] Reference Figures 5 to 6 The reset assembly 64 includes a guide post 6401. The top side of the guide post 6401 is fixedly connected to the top side of the inner wall of the wall 61 by welding, thus providing support for the guide post 6401. The outer side of the guide post 6401 is slidably connected to the inside of the pressing plate 63, guiding the pressing plate 63 to slide. A spring 6402 is sleeved on the outside of the guide post 6401, restricting the spring 6402 to ensure uniform force distribution. The top end of the spring 6402 is fixedly connected to the top side of the inner wall of the wall 61, ensuring uniform force distribution. The bottom end of the spring 6402 is fixedly connected to the top side of the pressing plate 63. The pressing plate 63 slides to compress the spring 6402, causing the spring 6402 to store elastic potential energy, which then applies a force in the opposite direction to the pressing plate 63 for reset. A guide cylinder 65 is fixedly connected to the bottom side of the reinforcing plate 62. By pushing the reinforcing plate 62 to slide, the guide cylinder 65 will then slide. The guide post 6401 is externally slidably connected to the inside of the guide cylinder 65, and the guide cylinder 65 guides the guide post 6401 to slide.

[0038] Two transmission plates 67 are fixedly connected to the bottom side of the guide cylinder 65 via a disc 66. The guide cylinder 65 slides, and the disc 66 drives the transmission plates 67 to slide. An extension plate 69 is slidably connected to the bottom end of the transmission plate 67 via a transmission column 68. The transmission column 68 transmits the sliding force of the transmission plate 67 to the two extension plates 69. An inclined opening is provided inside the extension plate 69, allowing for movement. The transmission column 68 is slidably connected to the inside of the inclined opening, guiding its sliding motion. Multiple extension plates 69 are slidably connected to the inside of the trapezoidal slope protection 1, reinforcing it by sliding into the slope protection 1. An anchor rod 610 is fixedly connected to the bottom side of the wall 61, reinforcing it by inserting the anchor rod 610 into the trapezoidal slope protection 1. The two extension plates 69 are slidably connected to the left and right ends of the bottom of the anchor rod 610, ensuring stable sliding by the anchor rod 610.

[0039] Working principle: When rainwater falls on the slope, the pebble layer 2 first buffers the rainwater, reducing its scouring force and also acting as a guide. Next, some rainwater flows down the slope to the intercepting ditch 5 at the top left end of the trapezoidal slope 1, where the sturdy nature of the pebbles resists the impact of the water flow and protects the bottom of the ditch. The impermeable soil-retaining layer 53 filters the rainwater, leaving soil particles to prevent loss. The water-passing cross-section layer 54 ensures rapid rainwater passage and secondary silt filtration. The scour-resistant layer 55 slows the water flow and protects the inner wall of the intercepting ditch 5. Finally, the rainwater flows into the diversion pipe 4 through the outlet 56 at the bottom of the intercepting frame 51. The diversion pipe 4 drains the rainwater from the slope, reducing the soil moisture content and maintaining the slope's dryness and stability.

[0040] By pushing the anchor rod 610 into the trapezoidal slope 1, and then releasing the upward tension on the reinforcing plate 62, the force of the spring 6402 returning to its original position is transmitted to the pressing plate 63, which then drives the guide cylinder 65 to slide downward, subsequently driving the disc 66 to slide. The disc 66 drives the two transmission plates 67 to slide, and then drives the transmission column 68 to slide. Subsequently, through the inclined opening inside the extension plate 69, the transmission column 68 can slide against the two extension plates 69 to the opposite side and extend into the interior of the trapezoidal slope 1. At the same time, if the slope is subjected to external pressure (such as soil expansion due to rainwater soaking), the pressure will act on the wall 61 of the pressure balancing mechanism 6. After the wall 61 is subjected to force, it transmits the pressure to the anchor rod 610, and the two outwardly extending extension plates 69 increase the stability of the installation, thereby strengthening the connection strength between the pressure balancing mechanism 6 and the slope, and realizing the balanced adjustment of the slope pressure.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
