Description

Technical Field

[0001] This utility model relates to the field of riverbank protection technology, and in particular to a riverbank protection vegetation fixing device. Background Technology

[0002] Riverbank vegetation stabilization devices are specialized equipment used in river ecological revetment projects. Their core function is to address the problems of poor ecological performance of traditional hard revetments and the susceptibility of simple vegetation revetments (or "vegetation substrate") to erosion through a combination of physical structure and ecological guidance. They can stabilize the vegetation substrate, resist water erosion, provide a stable environment for vegetation growth, restore the exchange of substances between water and land, contribute to biodiversity conservation, and achieve the dual goals of bank stabilization and ecological restoration. Common types include vegetation mats, eco-bags, and interlocking revetment bricks.

[0003] When using interlocking revetment bricks for ecological protection and stabilization of riverbanks, the core is to combine vegetation with the revetment through the pre-set planting cavities in the bricks. Adjacent bricks are interlocked laterally through side grooves, mortise and tenon structures, or metal connectors. In some construction processes, permeable mortar is also poured in after the bricks are spliced ​​to strengthen the horizontal shear resistance and prevent the bricks from being misaligned due to the lateral scouring of water flow. This ensures that the planting cavities form a continuous space for vegetation growth and provides a stable environment for the initial expansion of the root system.

[0004] However, the geological environment of riverbank revetments is complex and subject to long-term influence from natural factors and hydrological conditions, making it difficult to completely avoid the risk of longitudinal displacement. On the one hand, the foundation of riverbank slopes is mostly soft soil or backfill soil. If the compaction is insufficient during construction, or if the soil is affected by rainwater infiltration and groundwater level fluctuations over a long period, the foundation soil will gradually compress and deform, leading to settlement of the surface bricks (i.e., longitudinal displacement). On the other hand, the impact of floodwaters on the bottom of the slope may hollow out the soil at the toe, causing the upper soil to lose support and slide down the slope, resulting in longitudinal misalignment of the bricks (exacerbating longitudinal displacement). When bricks experience longitudinal displacement, they appear as some bricks bulging and others sinking, or sliding up and down the slope. The root system of the vegetation in the planting cavity is the first to be damaged, which can lead to root breakage of seedlings and affect their survival rate. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where longitudinal movement of bricks leads to breakage of seedling roots and affects seedling survival rates, and to propose a riverbank vegetation fixing device.

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

[0007] Design a riverbank vegetation fixing device, including a hexagonal brick, a planting trough is opened in the middle of the hexagonal brick, and a connecting groove is opened at equal intervals through the outer circumference of the hexagonal brick. A longitudinal limiting block is set in the connecting groove, and a connecting hole is vertically opened on the longitudinal limiting block. A fixing column is set in the connecting hole, and the fixing column is connected to a planar limiting mechanism.

[0008] Preferably, the inner wall of the planting trough is provided with an inclined surface, and the upper opening of the planting trough is larger than the lower opening.

[0009] Preferably, the inner wall of the planting trough is provided with multiple through holes, and the diameter of the through holes gradually decreases from the inside to the outside.

[0010] Preferably, the fixing column is made of stainless steel.

[0011] Preferably, the planar limiting mechanism includes a vertical groove, which is formed on the outer wall of the hexagonal brick. A limiting groove is formed on the inner wall of the vertical groove. An insertion part is inserted into the limiting groove. A slot is formed on both sides of the insertion part, and the slot abuts against the inner wall of the vertical groove.

[0012] Preferably, the lower end of the vertical groove is closed.

[0013] Preferably, the insertion part has a fixing hole, and the lower end of the fixing post extends into the fixing hole, which is a blind hole.

[0014] Preferably, the upper end of the fixing post is located inside the connecting hole.

[0015] The beneficial effects of the riverbank vegetation fixing device proposed in this utility model are: it can longitudinally connect and fix two adjacent hexagonal bricks, preventing local depressions or bulges in the hexagonal bricks, thereby avoiding root breakage of seedlings in the planting area and helping to ensure the survival rate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A riverbank vegetation fixing device includes hexagonal bricks 1, with a planting trough 13 in the middle of the hexagonal bricks 1 for planting vegetation. Connecting grooves 2 are equidistantly formed on the outer circumference of the hexagonal bricks 1. A longitudinal limiting block 8 is installed within the connecting groove 2, and a connecting hole 10 is vertically formed on the longitudinal limiting block 8. A fixing post 9 is installed within the connecting hole 10 and connected to a planar limiting mechanism. By placing the longitudinal limiting block 8 in the connecting groove 2, the device longitudinally connects and fixes adjacent hexagonal bricks 1, preventing local depressions or protrusions in the hexagonal bricks 1, thus avoiding root breakage of seedlings in the planting area and ensuring a high survival rate.

[0023] Example 2: Refer to Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, the inner wall of the planting trough 13 is provided with an inclined surface 3, and the upper opening of the planting trough 13 is larger than the lower opening. The inclined surface 13 can prevent the roots from spreading disorderly in the horizontal direction and from becoming congested and entangled in the upper part of the planting trough 13. Guiding the roots to grow downwards can make the root distribution more uniform and the layers clearer, which not only reduces local root competition, but also makes full use of the longitudinal space of the planting trough, providing sufficient space for the roots to spread out and promoting stronger root development.

[0024] Example 3: Reference Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 2, a plurality of through holes 5 are provided through the inner wall of the planting trough 13. The diameter of the through holes 5 gradually decreases from the inside to the outside. After the roots pass through the through holes 5, they can wrap around the adjacent hexagonal bricks. Furthermore, since the diameter of the through holes 5 is larger inside and smaller outside, it can prevent the roots from being squeezed and damaged at the point of exiting the trough. This allows the roots to more stably connect the bricks, thereby improving the overall resistance to water flow impact and slope slippage.

[0025] The fixed column 9 is made of stainless steel. Riverbank protection is constantly exposed to a humid environment and is susceptible to erosion from rainwater, river water, and corrosive substances in the soil. Stainless steel effectively resists corrosion, preventing the fixed column from weakening and failing due to corrosion, thus extending the overall service life of the equipment and reducing later maintenance costs. The upper end of the fixed column 9 is located inside the connecting hole 10, preventing the upper end of the fixed column 9 from protruding and avoiding the risk of collisions caused by the upper end of the fixed column protruding, ensuring safety during construction and later maintenance. On the other hand, it allows the fixed column 9 and the connecting hole 10 to form a tight nesting relationship. With the wrapping force of the hole wall on the column, the pull-out resistance of the fixed column is greatly enhanced, effectively preventing the fixed column 9 from being pulled out due to external forces such as water flow impact and slight slope displacement after the connection is completed, further improving the stability and reliability of the revetment structure.

[0026] Example 4: Reference Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 3, the planar limiting mechanism includes a vertical groove 4, which is formed on the outer wall of the hexagonal brick 1. A limiting groove 6 is formed on the inner wall of the vertical groove 4, and an insertion part 7 is inserted into the limiting groove 6. A locking groove 12 is formed on both sides of the insertion part 7, and the locking groove 12 abuts against the inner wall of the vertical groove 4. The lower end of the vertical groove 4 is closed. The limiting groove 6 limits the connection between the insertion parts 7, thus limiting the connection between the hexagonal bricks 1 in the plane, resisting the lateral thrust caused by water flow, preventing brick misalignment, preventing brick movement from squeezing or pulling the plant roots, reducing root breakage and damage, and ensuring stable plant growth.

[0027] The insertion part 7 has a fixing hole 11. The lower end of the fixing post 9 extends into the fixing hole 11. The fixing hole 11 is a blind hole. The bottom of the blind hole can form a vertical support for the fixing post 9. The insertion part 7 is connected to the fixing hole 11, which plays a limiting role for the longitudinal limiting block 8, preventing the longitudinal limiting block 8 from disengaging from the connecting groove 2, and ensuring the longitudinal connection effect of the hexagonal brick 1.

[0028] When connecting hexagonal bricks 1, first align the sides of adjacent hexagonal bricks 1, then insert the insertion part 7 into the limiting groove 6. Through the cooperation of the insertion part 7 and the limiting groove 6, the initial connection and fixation of the two hexagonal bricks 1 are achieved. Next, insert the longitudinal limiting block 8 into the connecting groove 2 at the joint of the two bricks. After aligning the fixing holes 11 corresponding to the connecting holes 10 on the two longitudinal limiting blocks 8, insert the fixing post 9 to complete the fixation of the longitudinal limiting block 8, further enhancing the connection stability between the hexagonal bricks 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
