Description

Technical Field

[0001] This utility model relates to the field of riverbank protection technology, specifically to an ecological flexible articulated block willow pile composite anchoring device. Background Technology

[0002] In engineering fields such as slope stabilization and riverbank protection, anchoring devices are core components for ensuring structural safety. They typically consist of an anchor head, an anchor rod, and an anchor body. The anchor head connects to the fixed object, transferring external forces to the anchor rod, which then distributes them to the foundation structure through the anchor body. This effectively resists various loads such as tension, shear, and bending moment, ensuring the stability and safety of slopes, riverbanks, and other areas.

[0003] Traditional anchoring devices mostly use rigid materials such as reinforced concrete and metal anchors to resist external forces (such as water flow impact, soil self-weight, and seismic loads) through "hard resistance". Although such structures can provide short-term high-strength anchoring, they cannot adapt to stress concentration caused by soil settlement, uneven foundation deformation, or dynamic loads (such as water level fluctuations and minor slope slippage). They are prone to overall failure due to local fractures and cracks. For example, precast concrete blocks or masonry structures commonly used in riverbank protection are prone to block detachment due to stress concentration under long-term water flow impact, and maintenance requires large-scale excavation, further damaging the surrounding environment. Therefore, an ecological flexible articulated block willow pile composite anchoring device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an ecological flexible articulated block willow pile composite anchoring device, which has the advantages of strong adaptability to deformation. It solves the problem that traditional rigid anchoring such as reinforced concrete and metal anchor rods cannot adapt to soil deformation and dynamic loads, and are prone to local fractures and cracks due to stress concentration, leading to overall failure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ecological flexible hinge block willow pile composite anchoring device, including a ground surface, shallow willow piles and deep willow piles, with multiple anchor rods evenly spaced below the ground surface, and flexible hinge blocks sleeved on the multiple anchor rods, with a flexible connector installed between each two flexible hinge blocks; The lower ends of multiple anchor rods are connected to shallow and deep willow piles via semi-rigid connectors. Each semi-rigid connector includes a connecting block sleeved on the anchor rod. An anchor cable, a buffer spring, and an installation block are sequentially arranged below each connecting block. Each anchor cable is used to connect the shallow and deep willow piles.

[0006] Preferably, the plurality of flexible hinge blocks are designed as block structures adapted to the anchor bolt arrangement, and the flexible hinge blocks have through holes in the middle for the anchor bolts to pass through.

[0007] Preferably, the flexible connector is a bendable rope-like structure, and its two ends are respectively connected to adjacent flexible hinge blocks.

[0008] Preferably, the top of each buffer spring is fixedly connected to the bottom of the connecting block, and the other end of each buffer spring is fixedly connected to the top of the mounting block.

[0009] Preferably, each of the anchor cables extends into the interior of the connecting block, and each buffer spring is sleeved on the surface of the anchor cable.

[0010] Preferably, the shallow willow piles are located in a shallower soil layer below the surface, and the deep willow piles are located in a deeper soil layer below the shallow willow piles.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This ecological flexible hinged block willow pile composite anchoring device can adaptively adjust its position according to the slight deformation of the soil by setting flexible hinged blocks and flexible connectors, thereby eliminating local stress concentration and avoiding the risk of fracture caused by the "hard confrontation" of traditional rigid structures; the buffer spring in the semi-rigid connector can further absorb the dynamic load energy such as water flow impact and earthquake, converting instantaneous strong external force into elastic deformation and delaying stress accumulation.

[0012] 2. This ecological flexible articulated block willow pile composite anchoring device combines shallow and deep willow piles. The shallow layer relies on soil friction to provide basic anchoring, while the deep layer uses soil and rock to enhance stability. The anchor rods are connected to achieve "shallow-deep" synergistic force. Even if there is local soil deformation, the overall anchoring efficiency can be maintained through stress redistribution of different structural layers, which greatly improves the long-term durability of the device and reduces the cost of repeated maintenance due to structural failure.

[0015] 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.

[0016] Please see Figure 1-3 An ecological flexible articulated block willow pile composite anchoring device in this embodiment includes a ground surface 1, shallow willow piles 2 and deep willow piles 3. The shallow willow piles 2 are located in a shallower soil layer below the ground surface 1, and the deep willow piles 3 are located in a deeper soil layer below the shallow willow piles 2. Multiple anchor rods 4 are arranged at equal intervals below the ground surface 1, and flexible articulated blocks 5 are sleeved on the multiple anchor rods 4. A flexible connector 6 is installed between every two flexible articulated blocks 5.

[0017] The lower ends of multiple anchor rods 4 are connected to shallow willow piles 2 and deep willow piles 3 through semi-rigid connectors 7. Each semi-rigid connector 7 includes a connecting block 701 sleeved on the anchor rod 4. An anchor cable 702, a buffer spring 703 and an installation block 704 are sequentially arranged below each connecting block 701. Each anchor cable 702 is used to connect the shallow willow pile 2 and the deep willow pile 3.

[0018] In this embodiment, when faced with external forces such as water flow impact and soil self-weight, the flexible hinge block 5 and flexible connector 6 first "flexibly respond," adjusting their posture according to the slight deformation of the soil to dissipate local stress; the buffer spring 703 in the semi-rigid connector 7 further absorbs and releases the load, transferring the force to the anchor cable 702; then the shallow willow pile 2 uses the friction of the soil layer and the deep willow pile 3 relies on the deep rock and soil embedding force, working together with the anchor rod 4 to disperse the external force to the foundation structure, like a relay race, unloading the force layer by layer, ensuring the stability of the slope and riverbank, just like putting an "elastic protective coat" on the soil, "softening-buffering-dispersing" when external forces come, and steadily bearing the load.

[0019] The device adapts to soil deformation through flexible hinge block 5 and flexible connector 6, buffers load with semi-rigid connector 7, and coordinates shallow willow piles 2 and deep willow piles 3 for anchoring. It not only solves the problem of failure of traditional rigid anchoring due to stress concentration, but also avoids secondary damage to the environment by taking advantage of the ecological properties and low disturbance design of willow piles. It achieves the dual goals of long-term stability and ecological friendliness of slope and riverbank protection, making the structure "breathable" and the environment "less damaged".

[0020] The flexible connector 6 is a bendable rope-like structure, and its two ends are respectively connected to the adjacent flexible hinge block 5.

[0021] In this embodiment, the flexible connector 6's bendability allows it to flexibly adjust its shape according to the relative displacement of adjacent flexible hinge blocks 5 caused by soil deformation, avoiding stress concentration caused by rigid connection during displacement and reducing the risk of breakage at the connection point; its rope-like structure is lightweight and easy to connect, facilitating quick assembly with adjacent flexible hinge blocks 5, reducing construction complexity and improving installation efficiency; the design of connecting adjacent flexible hinge blocks 5 at both ends can transfer the external force borne by a single flexible hinge block 5 to the surrounding blocks, realizing the distributed transfer of load and enhancing the overall structure's cooperative stress-bearing capacity.

[0022] The top of each buffer spring 703 is fixedly connected to the bottom of the connecting block 701, and the other end of each buffer spring 703 is fixedly connected to the top of the mounting block 704. Each anchor cable 702 extends into the interior of the connecting block 701, and each buffer spring 703 is sleeved on the surface of the anchor cable 702.

[0023] In this embodiment, the buffer spring 703 is fixedly connected to the connecting block 701 and the mounting block 704 at both ends, respectively. When subjected to external force, it can absorb impact energy through its own deformation, effectively buffering dynamic loads such as water flow impact and soil vibration, and avoiding stress concentration caused by the load acting directly on the connection part.

[0024] The buffer spring 703 is sleeved on the surface of the anchor cable 702, which can provide lateral restraint and protection for the anchor cable 702, reduce the shaking of the anchor cable 702 during the stress process or the friction with other components, and extend the service life of the anchor cable 702.

[0025] In this embodiment, the anchor cable 702 extends into the interior of the connecting block 701. Combined with the fixed connection method of the buffer spring 703, the load can be orderly transferred from the connecting block 701 through the buffer spring 703 and the mounting block 704 to the anchor cable 702, and then distributed by the anchor cable 702 to the shallow willow pile 2 and the deep willow pile 3, realizing the hierarchical transmission and distribution of force and improving the stress stability of the overall structure.

[0026] This structural design enables the buffer spring 703 and the anchor cable 702 to work synergistically. The buffer spring 703 provides elastic cushioning, while the anchor cable 702 ensures the effective transmission of force. The combination of the two can adapt to minor deformations while ensuring anchoring strength, thus enhancing the device's adaptability to complex working conditions.

[0027] In summary, this ecological flexible articulated block willow pile composite anchoring device includes a surface layer 1, shallow willow piles 2, deep willow piles 3, anchor rods 4, flexible articulated blocks 5, flexible connectors 6, and semi-rigid connectors 7. The semi-rigid connectors 7 further include a connecting block 701, an anchor cable 702, a buffer spring 703, and an installation block 704. During operation, the flexible articulated blocks 5 and flexible connectors 6 adjust their posture according to minor soil deformations to alleviate local stress. Then, the buffer spring 703 in the semi-rigid connectors 7 absorbs and mitigates the load, transferring it to the anchor cable 702. Finally, the load is released through the soil friction of the shallow willow piles 2 and the deep willow piles 3. The deep soil and rock embedment of pile 3, together with anchor rod 4, disperses external forces to the foundation structure, achieving layer-by-layer stress relief. This device, through the synergistic effect of its components, not only solves the problem of traditional rigid anchors failing due to stress concentration, but also avoids secondary environmental damage through the ecological properties and low-disturbance design of willow piles. Meanwhile, the flexible rope-like structure of flexible connector 6 reduces the risk of breakage, improves installation efficiency and overall synergistic stress-bearing capacity. The cooperation between buffer spring 703 and anchor cable 702 can buffer dynamic loads, protect anchor cable 702, and achieve layer-by-layer force transmission, enhancing structural stability and adaptability to complex working conditions.
