Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to an ecological slope protection structure for riverbank slopes in water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. River channel construction is a type of water conservancy project. During the construction of river channels, slope protection is required. River slope protection is to protect river slopes from severe erosion, which can lead to serious soil erosion and subsequent riverbank collapse. However, existing river slope protection structures are susceptible to soil erosion from the surface of vegetation under the scouring of rainwater or river water, which is not conducive to soil and water protection of river slopes. Utility Model Content

[0003] In order to address the problem described in the background art that existing riverbank slope protection structures suffer from soil and water loss on the surface of vegetation due to rainwater or river water erosion, which is not conducive to soil and water protection of riverbanks, this utility model proposes an ecological slope protection structure for riverbanks in water conservancy projects.

[0004] This utility model includes a riverbank slope as the main protective element. The surface of the riverbank slope is provided with a concrete protective frame. Inside the protective frame are slope protection plants planted within the riverbank slope. Several fixing grooves are formed on the surface of the riverbank slope. Several slots corresponding to the fixing grooves are formed on the protective frame. A soil stabilizing mechanism is embedded within each fixing groove. The soil stabilizing mechanism includes a soil stabilizing sheet, a waterproof sheet, and an anti-slip outer sheet. A through-groove is formed in the middle of each of the soil stabilizing sheet, the waterproof sheet, and the anti-slip outer sheet, surrounding the slope protection plants. The soil stabilizing sheet is positioned between the protective frame and the riverbank slope, covering the soil. A waterproof sheet made of waterproof material is placed on top of the soil stabilizing sheet. An anti-slip outer sheet is placed on top of the waterproof sheet to protect and fix it. Multiple telescopic baffles are set within the anti-slip outer sheet. These telescopic baffles can extend into the middle of the through-groove and support the slope protection plants.

[0005] Furthermore, the soil-stabilizing sheet is embedded in the fixing groove of the riverbank slope and connected to the slope soil by anchor bolts.

[0006] Furthermore, the waterproof membrane is disposed on the outside of the soil stabilization sheet and located inside the through groove of the protective frame. The size of the waterproof membrane is smaller than that of the soil stabilization sheet, and the edge of the waterproof membrane is sealed and bonded to the inner wall of the through groove of the protective frame. The waterproof membrane and the soil stabilization sheet form a stepped waterproof structure, preventing water from penetrating into the slope soil, reducing the saturated water content of the soil, and preventing the risk of landslides.

[0007] Furthermore, the anti-slip outer plate includes a protective outer layer and a fastening pad made of elastic material. The outer layer is snapped into the through groove of the protective frame, and the outer layer is fixedly connected around its perimeter with fastening pads that fit against the inner wall of the through groove of the protective frame.

[0008] Furthermore, the outer plate has multiple baffle receiving cavities on the groove surface of the through groove for placing telescopic baffles. The baffle receiving cavities are arranged in a two-stage stepped shape from the groove surface downwards, with the smaller one being larger than the larger one. One end of the telescopic baffle has a radially protruding convex plate, and one end of the telescopic baffle is placed in the cavity with the larger inner diameter in the baffle receiving cavity. The convex plate is used to prevent the telescopic baffle from falling out of the baffle receiving cavity. The other end of the telescopic baffle is provided with an arc-shaped fastening piece made of elastic material.

[0009] Furthermore, the top of the movable connecting end of the telescopic baffle is provided with a detachable end cover, which is snapped into the snap-fit ​​groove on the top of the outer layer plate.

[0010] Furthermore, the detachable end cap includes a sealing cap for sealing the top of the outer layer plate, a support spring made of elastic metal, and a clamping rubber gasket for fastening the sealing cap; one end of the sealing cap is provided with a clamping protrusion that engages with the bottom of the clamping groove of the outer layer plate; the support spring is fixedly installed inside the other end of the sealing cap, and the clamping rubber gasket is fixedly installed on the outer end of the support spring; the clamping rubber gasket is tightly fitted to the other end of the clamping groove of the outer layer plate; and a manually operable toggle block is provided on the top of the clamping rubber gasket.

[0011] Furthermore, the surface of the outer layer is provided with anti-slip texture. The anti-slip texture increases water flow resistance, reduces erosion speed, and, together with the waterproof membrane, enhances the slope's resistance to erosion.

[0012] Furthermore, the waterproof membrane is made of EPDM rubber. The rubber material used in the waterproof membrane can adapt to minor deformations of the slope.

[0013] Furthermore, the surface of the soil stabilizing plate is rough. The rough surface of the soil stabilizing plate can increase the friction with the soil, reduce the loss of topsoil caused by rainwater erosion, and further improve the soil stabilization efficiency.

[0014] Compared with the prior art, this utility model has the following advantages: (1) Multi-layer soil stabilization protection: By covering the soil around the plants with soil stabilization thin plates, the erosion and loss of exposed soil is reduced. Waterproof plates block rainwater and river water infiltration, reducing the risk of soil erosion. Anti-slip outer plates reinforce the overall structure, prevent the slope protection materials from slipping, and improve stability. Through the three-layer structure of soil stabilization thin plates (physical covering) + waterproof plates (chemical barrier) + anti-slip outer plates (mechanical reinforcement), gradient protection is constructed, which effectively solves the problem of soil erosion on river slopes. (2) High plant stability and strong adaptability: The telescopic baffle can be adjusted to adapt to the growth needs of different plants, provide dynamic support, and prevent plants from falling over; the through-groove design of the soil-stabilizing thin plate, waterproof plate and anti-slip outer plate ensures normal plant growth and limits the range of soil loss. (3) Modular construction and maintenance convenience: The protective frame can be made of precast concrete components, which are easy to assemble quickly on site and improve construction efficiency; the soil stabilization mechanism can be embedded in the fixing groove, which is easy to replace individually when damaged, reducing maintenance costs; (4) Ecological and engineering integration: Water-tolerant herbaceous slope protection plants such as reeds and calamus form a "plant-mechanical" composite soil stabilization system with the slope protection structure. Through the synergistic effect of ecological and engineering integration, the soil is stabilized and the ecological function is maintained. Compared with pure concrete slope protection, this structure takes into account both soil and water conservation and the needs of natural vegetation growth.

[0015] In summary, this utility model incorporates a soil-stabilizing thin plate between the riverbank slope and the protective frame to cover the soil. This plate secures the soil around the plants, reducing soil exposure. A waterproof and anti-slip outer plate further protects the plate, while an adjustable extension baffle adapts to different plant growth needs, providing dynamic support and preventing lodging. By combining mechanical soil stabilization with plant-based slope protection, this invention further enhances the fixation and protection of the soil within the riverbank slope, reducing soil erosion around the plants and effectively minimizing soil and water loss. It also improves the stability and durability of the slope protection structure, making it highly suitable for riverbank slope protection in water conservancy projects. Attached Figure Description

Detailed Implementation

[0017] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. The positional relationships described in the embodiments are consistent with those shown in the accompanying drawings.

[0018] An ecological slope protection structure for riverbanks in water conservancy projects, the whole structure is as follows: Figure 1 As shown, the riverbank slope 1 serves as the main protective structure. A concrete protective frame 2 is installed on the surface of the riverbank slope 1, and slope-stabilizing plants 3 are planted inside the protective frame 2. Specifically, several fixing grooves are formed on the surface of the riverbank slope 1, and several corresponding slots are formed on the protective frame 2. Soil-stabilizing mechanisms are embedded within the fixing grooves. The protective frame 2, formed by concrete pouring onto the surface of the riverbank slope 1, creates a rigid frame. Its internal slots provide planting space for the slope-stabilizing plants 3 while restricting soil displacement. The concrete resists water erosion and freeze-thaw damage. In this embodiment, the fixing grooves of the riverbank slope 1 are arranged in a grid pattern, meaning the soil-stabilizing mechanism is also arranged in a grid pattern.

[0019] like Figure 2 and Figure 3 As shown, the soil stabilization mechanism consists of a soil stabilization sheet 4, a waterproof sheet 5, and an anti-slip outer sheet 6. Each of the soil stabilization sheet 4, waterproof sheet 5, and anti-slip outer sheet 6 has a channel in its center, which surrounds the outer side of the slope protection vegetation 3. The soil stabilization sheet 4 is positioned between the protective frame 2 and the riverbank slope 1, covering the soil. A waterproof sheet 5 made of waterproof material is placed on top of the soil stabilization sheet 4. An anti-slip outer sheet 6 is placed on top of the waterproof sheet 5 to protect and fix it. Multiple telescopic baffles 7 are installed in the anti-slip outer sheet 6, which can extend into the center of the channel and support the slope protection vegetation 3.

[0020] The soil stabilizing sheet 4 is fixedly connected to the interior of the riverbank slope 1. Specifically, the soil stabilizing sheet 4 is embedded in the fixing groove of the riverbank slope 1 and connected to the slope soil by anchor bolts. The soil stabilizing sheet 4 covers the exposed soil surface. The through groove in the middle of the soil stabilizing sheet 4 allows the slope protection vegetation 3 to pass through. The surface of the soil stabilizing sheet 4 is rough, which increases the friction with the soil, reduces the loss of topsoil caused by rainwater erosion, and further improves the soil stabilization efficiency.

[0021] The waterproof membrane 5 is installed on the outside of the soil stabilization sheet 4 and inside the protective frame 2. The size of the waterproof membrane 5 is smaller than that of the soil stabilization sheet 4, and the edge of the waterproof membrane 5 is sealed and bonded to the inner wall of the through groove of the protective frame 2. The waterproof membrane 5 can be made of EPDM rubber. The waterproof membrane 5 and the soil stabilization sheet 4 form a stepped waterproof structure, preventing water from penetrating into the slope soil, reducing the saturated water content of the soil, and preventing the risk of landslides. The rubber material used in the waterproof membrane 5 can adapt to minor deformations of the slope.

[0022] like Figure 3 As shown, the anti-slip outer plate 6 is composed of an outer protective plate 61 and fastening pads 62 made of elastic material. The outer plate 61 is snapped into the through groove of the protective frame 2, and the fastening pads 62, which are in contact with the inner wall of the through groove of the protective frame 2, are fixedly connected around the outer plate 61. The fastening pads 62 can be made of neoprene rubber. The fastening pads 62 fill the gaps to form an elastic seal. The surface of the outer plate 61 can be provided with anti-slip texture to increase water flow resistance and reduce erosion speed. Together with the waterproof plate 5, this improves the slope's resistance to erosion.

[0023] Multiple baffle receiving cavities are provided on the groove surface of the outer plate 61. The baffle receiving cavities are arranged in a two-stage stepped pattern, starting from the groove surface and gradually increasing in size. One end of the telescopic baffle 7 has a radially protruding convex plate, and this end is movably connected to the radially larger cavity within the baffle receiving cavity. The convex plate prevents the telescopic baffle 7 from detaching from the baffle receiving cavity. The other end of the telescopic baffle 7 is provided with an arc-shaped fastening piece 9 made of elastic material. The telescopic baffle 7 slides within the outer plate 61, and its arc-shaped fastening piece 9 conforms to the stem of the slope protection plant 3, providing support through elastic deformation to prevent the plant from falling over. The baffle's telescopic extension adapts to the plant at different growth stages, and the convex design prevents the telescopic baffle 7 from falling off.

[0024] like Figure 3 and Figure 4 As shown, a detachable end cap 8 is provided on the top of the movable connecting end of the telescopic baffle 7. The detachable end cap 8 is snapped into the snap-fit ​​groove on the top of the outer layer plate 61. The detachable end cap 8 includes a sealing cap 81 that seals the top of the outer layer plate 61, a support spring 82 made of elastic metal, and a clamping rubber gasket 83 that secures the sealing cap 81. One end of the sealing cap 81 is provided with a snap-fit ​​boss 10 that snaps into the bottom of one end of the snap-fit ​​groove of the outer layer plate 61. The support spring 82 is fixedly installed inside the other end of the sealing cap 81, and the clamping rubber gasket 83 is fixedly installed on the outer end of the support spring 82. The clamping rubber gasket 83 is fitted and secured to the other end of the snap-fit ​​groove of the outer layer plate 61. A manually operable toggle block is provided on the top of the clamping rubber gasket 83. The clamping pad 83 can be supported by silicone rubber. The sealing cover 81 engages with the outer plate 61 through the snap-fit ​​protrusion 10. The internal support spring 82 pushes the clamping pad 83 to seal the gap. The locking can be released by moving the toggle block on the top of the clamping pad 83, which can help adjust the position of the telescopic baffle 7, making it easier to fill the groove with planting soil or replace the plant.

[0025] The working principle of this slope protection structure is as follows: A protective frame 2 is poured on the surface of the riverbank slope 1 to form a rigid frame. A soil stabilizing sheet 4 is embedded in the fixing groove of the riverbank slope 1. The groove of the soil stabilizing sheet 4 allows plants to pass through to fix the topsoil. A waterproof sheet 5 is laid on the outside of the soil stabilizing sheet 4. Its edge is sealed with the protective frame 2 and then fixed by the outer layer 61 of the anti-slip outer plate 6. The surrounding tight rubber pads 62 form an elastic seal. The anti-slip texture on the surface of the outer layer 61 reduces the scouring speed of the water flow. The telescopic baffle 7 slides in the outer layer 61. Its arc-shaped fastening piece 9 elastically fits the plant stem to prevent it from falling over. The sealing cover 81 of the disassembly end cover 8 is used to lock the outer layer 61. The support spring piece 82 pushes the tight rubber pad 83 to seal the gap. The locking can be released by moving the toggle block, which can help adjust the position of the telescopic baffle 7, so as to facilitate filling the groove with planting soil or replacing the plants, realizing the coordinated operation of slope protection and plant support.

However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
