The stability control of soil slope is the key link to ensure engineering safety and ecological environment, especially in the mining area of water conservation, the supporting structure not only needs to have the function of slope reinforcement, but also needs to consider water resource protection.

[0003] In the prior art, the soil slope supporting method mainly consists of rigid support and flexible support, the rigid support can provide strong support but cannot adapt to complex terrain, the flexible support can adapt to terrain but the supporting capacity and structural stability are insufficient, especially for soil slope with complex terrain and concave-convex, the existing supporting structure either needs high cost and environmental cost to adapt to the structure or cannot effectively match the slope surface, resulting in low supporting effect and serious safety hidden danger. SUMMARY

[0004] In view of the above shortcomings of the prior art, the present application provides an energy dissipation supporting structure for reinforcing soil slope, which can effectively solve the problem that in the prior art, the soil slope supporting method mainly consists of rigid support and flexible support, the rigid support can provide strong support but cannot adapt to complex terrain, the flexible support can adapt to terrain but the supporting capacity and structural stability are insufficient, especially for soil slope with complex terrain and concave-convex, the existing supporting structure either needs high cost and environmental cost to adapt to the structure or cannot effectively match the slope surface, resulting in low supporting effect and serious safety hidden danger.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme:

[0006] The present application provides an energy dissipation supporting structure for reinforcing soil slope, comprising:

[0007] An anchoring unit, the anchoring unit comprises a fixed pile, a connecting ball groove is formed on the outer surface of the fixed pile, a communication hole is formed in the middle part of the fixed pile, a plurality of connecting ball grooves are provided, and the plurality of connecting ball grooves are distributed in a circular array with the communication hole as the center;

[0008] A supporting unit, the supporting unit comprises a supporting frame, a cavity is formed in the middle part of the supporting frame, and a protective net is arranged in the cavity;

[0009] The energy dissipation unit includes a spherical bearing, wherein the spherical outer surface of the spherical bearing is in rolling connection with the inner wall surface of the connecting spherical groove, and a sleeve is embedded in the support frame near the corner.

[0010] Furthermore, the anchoring unit also includes an anchor rod, the outer end of which passes through a connecting hole and is embedded inside the slope, and the outer surface of the anchor rod adopts a threaded structure design.

[0011] Furthermore, the fixed pile adopts a regular hexagonal structure design, and the support frame adopts a triangular structure design.

[0012] Furthermore, the end of the spherical bearing away from the fixed pile penetrates the outer surface of the sleeve and is fixedly connected to a piston head, the outer circumferential surface of the piston head being in contact with the inner wall surface of the sleeve.

[0013] Furthermore, a viscous fluid is provided inside the sleeve, and the viscous fluid is distributed on both sides of the piston head.

[0014] Furthermore, the plant protection net adopts a double-layer structure, which includes an upper layer net and a lower layer net. The upper layer net and the lower layer net are distributed from top to bottom. The outer surfaces of the upper layer net and the lower layer net are fixedly connected to the inner wall surface of the cavity. The interior of the upper layer net and the lower layer net are provided with hollow openings.

[0015] Furthermore, the support frame has a hollow layer that communicates with the cavity inside. A hollow frame is slidably connected inside the hollow layer. A connecting rod is fixedly connected to the outer surface of the hollow frame. The outer end of the connecting rod extends into the sleeve and is fixedly connected to the outer surface of the piston head.

[0016] Furthermore, three hollow frames are provided, and the three hollow frames are stacked and their internal hollow parts are interconnected to form a triangular mesh. The triangular mesh is formed by the overlapping hollow areas of the three hollow frames, and the area of ​​the hollow opening is larger than the area of ​​the triangular mesh.

[0017] The three hollow frames are stacked on top of each other at a 120-degree angle. The upper surface of the upper hollow frame is in contact with the lower surface of the upper mesh, and the lower surface of the lower hollow frame is in contact with the upper surface of the lower mesh.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] 1. This invention includes a support frame, fixed piles, spherical bearings, and sleeves. The support structure uses a spherical bearing connecting the fixed piles and the support frame to create a universal hinge design, allowing the support frame to rotate around the fixed piles within a small range and at multiple angles. This enables it to adapt to changes in the overall slope inclination (such as the transition between steep and gentle slopes) and local unevenness of the slope. It eliminates the need for slope cutting and leveling, reduces earthwork volume, and avoids disturbance of the original soil, thus reducing the risk of instability during construction from the source.

[0020] 2. While existing flexible netting can adapt to slope undulations, it is prone to becoming suspended in areas of rapid slope change and localized unevenness. These suspended sections cannot transmit geological pressure, and stress concentration points can lead to damage to the netting or anchorages. In contrast, in this structure, fixed piles are embedded into deep, stable strata via anchor rods. The support frame is universally connected to the fixed piles via spherical bearings. When there is a localized bulge, the edges of the support frame can be rolled away from the bulge using the spherical bearings, with controllable offset and no suspended areas. When there is a localized depression, the support frame can rotate using the spherical bearings to form a cantilevered cover. Simultaneously, adjacent support frames distribute the load to multiple fixed piles through a triangular structure, eliminating stress concentration points and ensuring that the overall protective effect is not weakened.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to embodiments.

[0033] Example:

[0034] Please see Figures 1-8 This invention provides a technical solution: an energy dissipation support structure for reinforcing soil slopes, comprising:

[0035] Anchoring unit 1 includes a fixed pile 11. The outer surface of the fixed pile 11 is provided with a connecting ball groove 111. The middle part of the fixed pile 11 is provided with a connecting hole 112. Multiple connecting ball grooves 111 are provided and are arranged in a circular array around the connecting hole 112.

[0036] Support unit 2 includes support frame 21, with cavity 211 in the middle of support frame 21, and planting net 22 installed inside cavity 211.

[0037] Energy dissipation unit 3 includes a ball bearing 31, the outer spherical surface of the ball bearing 31 is in rolling connection with the inner wall surface of the connecting ball groove 111, and a sleeve 32 is embedded in the support frame 21 near the corner.

[0038] The anchoring unit 1 also includes an anchor rod 12, the outer end of which passes through the connecting hole 112 and is embedded inside the slope. The outer surface of the anchor rod 12 adopts a threaded structure design.

[0039] The fixed pile 11 adopts a regular hexagonal structure design, and the support frame 21 adopts a triangular structure design.

[0040] The end of the ball bearing 31 away from the fixed pile 11 passes through the outer surface of the sleeve 32 and is fixedly connected to the piston head 33. The outer circumferential surface of the piston head 33 is in contact with the inner wall surface of the sleeve 32.

[0041] The sleeve 32 is provided with a viscous fluid 34, which is distributed on both sides of the piston head 33.

[0042] The planting net 22 adopts a double-layer structure, which includes an upper net 221 and a lower net 222. The upper net 221 and the lower net 222 are distributed from top to bottom. The outer surfaces of the upper net 221 and the lower net 222 are fixedly connected to the inner wall surface of the cavity 211. The upper net 221 and the lower net 222 are both provided with hollow openings 2211.

[0043] The support frame 21 has a hollow layer 212 that communicates with the cavity 211. A hollow frame 23 is slidably connected inside the hollow layer 212. A connecting rod 231 is fixedly connected to the outer surface of the hollow frame 23. The outer end of the connecting rod 231 extends into the sleeve 32 and is fixedly connected to the outer surface of the piston head 33.

[0044] There are three hollow frames 23, which are stacked and their internal hollow parts are interconnected to form a triangular mesh 232. The triangular mesh 232 is formed by the overlapping hollow areas of the three hollow frames 23. The area of ​​the hollow opening 2211 is larger than the area of ​​the triangular mesh 232, and the number of triangular mesh 232 and hollow opening 2211 is the same.

[0045] The three hollow frames 23 are stacked on top of each other at a 120-degree angle. The upper surface of the upper hollow frame 23 is in contact with the lower surface of the upper mesh 221, and the lower surface of the lower hollow frame 23 is in contact with the upper surface of the lower mesh 222.

[0046] In existing technologies, soil slope protection methods are mainly divided into two categories: rigid support and flexible support. Rigid structures usually require construction on a flat base. For the commonly existing uneven natural slopes, large-scale slope cutting and leveling are necessary to build retaining walls or cast grid beams, which greatly increases the amount of earthwork. At the same time, large-scale excavation will severely disturb the original soil, destroy its natural structure, and induce new instability risks during construction. Although flexible mesh can adapt to a certain degree of slope undulation, its support strength depends on the tight fit between the mesh and the slope and the effective fixation of the anchor points. In areas with slope changes and local unevenness, the flexible mesh is prone to suspension. The suspended parts cannot effectively transmit soil pressure, and stress concentration points can lead to local damage to the mesh or anchors, thereby weakening the overall protection effect.

[0047] The anchoring unit 1 serves as the foundation for connecting the entire support structure to the stable stratum. Its core is the fixed pile 11. In this embodiment, the fixed pile 11 preferably adopts a regular hexagonal structure design, which offers better directional stability and torsional resistance compared to circular or square structures. Each of the six faces of the fixed pile 11 has a connecting ball groove 111 at its center. These connecting ball grooves 111 are arranged in a circular array, centered on the connecting hole 112 in the center of the fixed pile 11. To firmly embed the fixed pile 11 into the slope, the anchoring unit 1 also includes an anchor rod 12. The outer surface of the anchor rod 12 has a threaded groove. Its outer end penetrates the connecting hole 112 and is embedded into the stable soil layer or bedrock deep within the slope through drilling and grouting, forming a reliable anchoring force.

[0048] Installation and initial state:

[0049] First, anchor holes are drilled on the slope to be reinforced, and anchor rods 12 are inserted and grouted for fixation. Then, fixing piles 11 are fitted onto the outer end of anchor rods 12 through their connecting holes 112 and tightened to ensure that fixing piles 11 are tightly fitted to the slope surface. At this point, fixing piles 11 are firmly fixed to the slope surface.

[0050] The corners of the support frame 21 are aligned with the connecting ball grooves 111 of the fixed piles 11. A portion of the spherical bearing 31 is embedded in the connecting ball grooves 111, forming a universal hinge connection. The other end of the spherical bearing 31 is inserted into a sleeve 32 pre-embedded inside the corner of the support frame 21. The spherical outer surface of the spherical bearing 31 is in a rolling connection with the inner wall of the connecting ball groove 111, which allows the support frame 21 to rotate within a small range of multiple angles relative to the fixed piles 11. This perfectly adapts to uneven and complex slopes, ensuring that each support frame 21 can effectively conform to the slope, avoiding the huge costs and environmental damage caused by traditional rigid structures for slope cutting and leveling.

[0051] Inside the sleeve 32, a viscous fluid 34, such as silicone oil, is pre-filled. A piston head 33 is fixedly connected to the end of the ball bearing 31. The outer circumferential surface of the piston head 33 is in close contact with the inner wall surface of the sleeve 32, dividing the interior of the sleeve 32 into two independent chambers, which are filled with the viscous fluid 34.

[0052] The fixed pile 11 adopts a regular hexagonal structure with six faces, each corresponding to a support frame 21. The support frame 21 has a triangular structure design, with its corners corresponding to the sides of the fixed pile 11. With the fixed pile 11 as the center, the six support frames 21 are evenly distributed around its perimeter, with the angle between any two adjacent support frames 21 being 60 degrees. With the support frame 21 as the center, three fixed piles 11 are evenly distributed at the three corners of the support frame 21, with the angle between any two adjacent fixed piles 11 being 120 degrees. Multiple sets of fixed piles 11 and support frames 21 are connected by energy dissipation units 3, forming a large-area support structure.

[0053] Inside the support frame 21, in addition to the cavity 211, there is a hollow layer 212 that communicates with the cavity 211. A perforated frame 23 is slidably connected inside the hollow layer 212. Three perforated frames 23 are provided, and the three frames 23 are stacked on top of each other to form a stable triangular mesh 232. A connecting rod 231 is fixedly connected to the outer surface of each perforated frame 23, and the outer end of the connecting rod 231 extends into the sleeve 32 and is fixedly connected to the outer surface of the piston head 33.

[0054] The upper surface of the uppermost perforated frame 23 is in contact with the lower surface of the upper layer net 221 in the planting net 22; the lower surface of the lowermost perforated frame 23 is in contact with the upper surface of the lower layer net 222 in the planting net 222, and the perforations 2211 inside the upper layer net 221 and the lower layer net 222 are completely aligned. At the same time, the area of ​​the perforations 2211 on the planting net 22 is larger than the area of ​​the triangular mesh 232 formed by the perforated frame 23. Therefore, in actual use, the actual area on which plants grow from the outer surface of the slope is equal to the area of ​​the triangular mesh 232.

[0055] When the slope undergoes an overall change in tilt angle (such as transitioning from a steeper slope to a gentler slope), the anchoring unit 1 adjusts the installation angle of the fixing piles 11 according to the slope tilt direction. The rotation of the spherical bearing 31 within the connecting groove 111 keeps the triangular plane of the support frame 21 parallel to the slope tilt direction. For example, when the slope tilts downwards to the right, the spherical bearing 31 near the downward right inflection point rolls along the inside of the connecting groove 111, causing the support frame 21 near the downward right inflection point to tilt with the slope, preventing the frame from forming an angle with the slope and experiencing stress.

[0056] Simultaneously, the piston head 33 of the energy dissipation unit 3 experiences slight sliding within the sleeve 32. When the slope inclination causes a height difference at the corners of the support frame 21, the connecting rod 231 drives the piston head 33 to compress the viscous fluid 34 on one side. The viscous resistance of the fluid not only consumes the impact energy during the adjustment process but also stabilizes the adjustment posture through fluid pressure. Ultimately, the triangular structure of the support frame 21, through multi-directional rotation and sliding adjustment, ensures that the support frame 21 always remains in contact with the slope, preventing localized pulling or loosening of the vegetation net 22 and the slope surface due to inclination.

[0057] When there are local protrusions on the slope, the protruding parts directly contact the corners of the support frame 21. The compressive force generated by the protrusion is transmitted to the sleeve 32. At this time, the ball bearing 31 rolls in the connecting ball groove 111, causing the corners of the support frame 21 to shift away from the protrusion. The amount of shift can be controlled by the rotation angle of the ball bearing 31, just avoiding the compression range of the protrusion. At the same time, the piston head 33 inside the sleeve 32 slides as the sleeve 32 shifts. The viscous fluid 34 flows through the gap between the piston head 33 and the inner wall of the sleeve 32, consuming the impact energy generated by the protrusion and preventing the corners of the frame from cracking due to the hard resistance to the protrusion.

[0058] After the protrusion causes a single support frame 21 to shift, the adjacent support frames 21 transmit the force to three sides through their own triangular structure: the spherical bearings 31 of the adjacent support frames 21 rotate synchronously, and through the circumferential array distribution characteristics of the connecting ball grooves 111, the local load of the protrusion is distributed to multiple fixed piles 11, and then transmitted to the deep soil of the slope through the anchor rods 12, so as to avoid support failure caused by local stress concentration at the protrusion.

[0059] Static working state:

[0060] Under normal circumstances, the lateral earth pressure of the slope soil is transmitted to the support frame 21 through the vegetation net 22. The force on the support frame 21 is transmitted to the fixed pile 11 through the sleeves 32 and ball bearings 31 embedded in its corners, and finally to the deep stable strata by the anchor rods 12. At this time, due to the small and stable load, the piston head 33 remains basically stationary inside the sleeve 32, and the energy dissipation unit 3 mainly plays the role of connection and force transmission.

[0061] The perforated frame 23 is fixedly connected to the outer end of the piston head 33 via a connecting rod 231. Three perforated frames 23 are stacked and located inside the hollow layer 212. The three layers of perforated frames 23 are stacked, and their perforated parts interweave to form triangular mesh holes 232. The number of triangular mesh holes 232 is the same as the number of perforated openings 2211. The triangular mesh holes 232 are completely within the range of the perforated openings 2211, allowing plant seeds to be planted into the slope soil through the perforated openings 2211 and the triangular mesh holes 232.

[0062] After the seeds are sown on the slope covered by the planting net 22, they first absorb water and germinate in the soil. After the seedlings emerge from the soil, their stems and leaves grow outward through the perforations 2211 and triangular mesh 232 of the planting net 22. However, as time goes by, and the plants gradually grow, their roots spread in the soil, and their above-ground branches and leaves become more lush, it will be found that the growth range of the plants basically coincides with the boundary of the triangular mesh 232.

[0063] Dynamic energy dissipation process:

[0064] When the slope encounters vibrations such as earthquakes, rainstorms, sudden impacts, or vehicle traffic, the load acting on the support frame 21 will increase sharply and generate dynamic impacts.

[0065] Vibration of shallow soil will generate lateral thrust or vertical disturbance force on the fixed pile 11. However, because the anchor rod 12 is locked to the deep stable soil (dense clay layer, weathered rock layer) through the threaded groove, the fixed pile 11 is firmly fixed in the initial anchoring position. Only the surface of the pile body will bear the vibration stress transmitted by the soil, and it will not move as a whole. The vibration stress borne by the fixed pile 11 is transmitted to the spherical bearing 31 through the connecting ball groove 111. Since the spherical bearing 31 and the connecting ball groove 111 are in a spherical rolling fit, the vibration stress is converted into a torque that pushes the spherical bearing 31 to rotate along the inner wall of the connecting ball groove 111, and at the same time drives the piston head 33, which is fixedly connected to the spherical bearing 31, to generate a tendency to move.

[0066] The movement trend of the piston head 33 is transmitted to the hollow frame 23 through the connecting rod 231, which in turn causes the support frame 21 to produce a displacement trend consistent with the direction of soil vibration (such as left and right swaying in the horizontal direction and up and down swaying in the vertical direction). At this time, the support frame 21 acts as a slope protection carrier, which evenly distributes the vibration load to the entire triangular structure and avoids local stress concentration.

[0067] The thrust forces the support frame 21 to move outwards from the slope. Since the support frame 21 is connected to the fixed pile 11 via a ball bearing 31, this tendency to move is translated into axial movement of the piston head 33 within the sleeve 32. As the piston head 33 moves axially within the sleeve 32, it forcefully compresses the viscous fluid 34 in front of it. The viscous fluid 34 is forced to flow from the high-pressure chamber to the low-pressure chamber through the tiny gap between the piston head 33 and the inner wall of the sleeve 32, or through a pre-set damping hole on the piston head 33. This process generates a huge damping force, converting a large amount of the kinetic energy of the impact load into heat energy and dissipating it, thereby significantly reducing the peak load transmitted to the anchoring system and protecting the safety of the anchoring unit 1 and the deep slope.

[0068] Using the connecting ball groove 111 of the fixed pile 11 as a fixed fulcrum, the spherical outer surface of the spherical bearing 31 achieves multi-directional rolling along the inner wall of the connecting ball groove 111. If the vibration direction is horizontal, the spherical bearing 31 rotates horizontally along the connecting ball groove 111, causing the support frame 21 to sway laterally with the soil. If the vibration direction is oblique, the spherical bearing 31 rolls obliquely along the connecting ball groove 111, satisfying the tilt displacement of the support frame 21 and avoiding the breakage caused by the angle mismatch of traditional rigid connections.

[0069] After the impact load, the piston head 33 will gradually slow down and eventually stop moving due to the rebound force of the slope itself and the damping effect of the viscous fluid 34. Due to the universal joint effect of the ball bearing 31, the support frame 21 can adaptively return to the equilibrium position that fits the slope surface without permanent misalignment or jamming.

[0070] Because the area of ​​the perforated opening 2211 of the vegetation net 22 is larger than the area of ​​the triangular mesh 232, and the perforated frame 23 is fixedly connected to the piston head 33 in the energy dissipation unit 3 via the connecting rod 231, when the slope vibrates, the position of the fixed pile 11 is relatively stationary, while the perforated frame 23 is fixedly connected to the ball bearing 31 inside the fixed pile 11 via the connecting rod 231 and the piston head 33. Therefore, the positions of the perforated frame 23, the fixed pile 11, and the vegetation on the upper surface of the slope are relatively stationary, while the support frame 21 and the vegetation net 22 inside it are displaced under the action of the energy dissipation unit 3. The position of the perforated frame 23 and the plant roots is relatively stationary, while the position of the vegetation net 22 and the perforated opening 2211 inside it moves relative to the plant roots. However, because the area of ​​the perforated opening 2211 in the vegetation net 22 is larger than the area of ​​the triangular mesh 232 in the initial case, a pre-reserved margin is provided. This avoids the situation where, when both the planting netting 22 and the perforated frame 23 shift, the holes between them would trap the plants along with them, leading to the pulling and breaking of the plant roots. Especially for plants whose roots have penetrated deep into the slope soil, the relative displacement of the roots, soil, and planting netting 22 would severely damage the root structure, reduce the soil-stabilizing effect, and even cause plant death, weakening the ecological slope protection function. Therefore, by providing a margin in the area of ​​the perforated openings 2211 inside the planting netting 22 and maintaining the relative stillness between the perforated frame 23 and the fixed piles 11, the netting adapts to displacement through expansion, contraction, and slight deformation, preventing the roots from being pulled as a whole, protecting the plant roots, reducing rigid tension, and preserving the ecological soil-stabilizing effect.

[0071] In summary, the support unit 2 and energy dissipation unit 3 have the following advantages:

[0072] Advantage 1: Existing rigid supports require construction on a flat base surface. For uneven natural slopes, large-scale slope cutting is necessary, which not only increases the amount of earthwork but also disturbs the original soil, damages the natural structure, and induces the risk of instability during construction. This support structure uses a ball bearing 31 connecting the fixed pile 11 and the support frame 21 to a ball groove 111 universal hinge design, which allows the support frame 21 to rotate around the fixed pile 11 in a small range and at multiple angles. It can adapt to the overall tilt changes of the slope (such as the transition between steep and gentle slopes) and local unevenness, without the need for slope cutting and leveling. This reduces the amount of earthwork and avoids disturbance of the original soil, reducing the risk of instability during construction from the source.

[0073] Advantage 2: While existing flexible nets can adapt to certain slope undulations, they are prone to becoming suspended in areas with rapid slope changes and local unevenness. Suspended portions cannot transmit soil pressure, and stress concentration points can lead to damage to the netting or anchors. In this structure, the fixed piles 11 are embedded into deep, stable strata through anchor rods 12, and the support frame 21 is universally connected to the fixed piles 11 through ball bearings 31. When there is a local bulge, the corners of the support frame 21 can be rolled away from the bulge by the ball bearings 31 to avoid it, with controllable offset and no suspended areas. When there is a local depression, the support frame 21 can be rotated by the ball bearings 31 to form a cantilevered cover. At the same time, adjacent support frames 21 distribute the load to multiple fixed piles 11 through a triangular structure, eliminating stress concentration points and ensuring that the overall protection effect is not weakened.

[0074] Thirdly, existing anchorage foundations for supports are mostly circular or square structures, which have poor directional stability and weak torsional resistance, making them prone to torsional displacement under load. The fixed pile 11 in this structure adopts a regular hexagonal design, which increases the contact area with the soil compared to circular or square structures, and the six sides can evenly distribute the load, improving directional stability. At the same time, the regular hexagonal structure has a larger torsional section modulus, enhancing torsional resistance and effectively resisting torsional loads generated by vibration or soil pressure, preventing torsional deformation of the fixed pile 11.

[0075] Fourthly, this structure centers on the fixed pile 11, with six support frames 21 evenly distributed around the circumference, extending outwards in multiple groups. Each support frame 21 is triangular in design, with its three corners connected to three fixed piles 11 (the included angle between adjacent fixed piles 11 is 120 degrees). Multiple groups of fixed piles 11 and support frames 21 are spliced ​​together through energy dissipation units 3 to form a large-area support system. In a static state, lateral earth pressure travels through the vegetation net 22, support frames 21, sleeves 32, spherical bearings 31, fixed piles 11, and anchor rods 12 before finally reaching the deep, stable strata. The force transmission path is clear and stress-free. Under localized stress, the load can be quickly dispersed to multiple anchor points through the triangular frames and the circumferentially distributed fixed piles 11, avoiding structural damage caused by localized overload.

[0076] Fifthly, in the energy dissipation unit 3 of this structure, the sleeve 32 is filled with viscous fluid 34, and the piston head 33 is tightly attached to the inner wall of the sleeve 32. During vibration, the displacement of the support frame 21 causes the piston head 33 to slide back and forth in the sleeve 32. The viscous fluid 34 is forced to flow through the gap between the piston head 33 and the sleeve 32. The friction of fluid molecules converts the vibration kinetic energy into heat energy dissipation, which significantly reduces the peak load transmitted to the anchoring unit 1 and protects the anchoring unit 1 and the deep slope body.

[0077] Advantage 6: In existing ecological support systems, structural displacement easily leads to the pulling and breaking of plant roots, weakening the ecological soil stabilization effect. This structure's plant protection net 22 adopts a double-layer design (upper net 221, lower net 222), with internal perforations 2211. Three perforated frames 23 within the hollow layer 212 of the support frame 21 overlap to form multiple triangular mesh holes 232, and the area of ​​the perforations 2211 is larger than the mold of the triangular mesh holes 232, allowing for displacement allowance. During vibration, the fixed pile 11 and the perforated frames 23 remain relatively stationary (the perforated frames 23 are connected to the piston head 33 and the ball bearing 31 via connecting rods 231, and the ball bearing 31 is hinged to the fixed pile 11). The support frame 21 and the plant protection net 22 move with the energy dissipation unit 3, and the perforations 2211 move within the range of the triangular mesh holes 232, without rigidly pulling on the plant roots. Meanwhile, the triangular mesh 232 provides a stable growth boundary for the roots, avoiding stress damage caused by disordered root spread and ensuring that the effect of plant soil fixation is not weakened.
