Description

Technical Field

[0001] This invention relates to the field of ecological slope protection technology, specifically to an ecological slope protection block connector and an ecological slope protection system. Background Technology

[0002] Ecological slope protection blocks are commonly used slope protection components in river, lake, reservoir, municipal water system, and road slope protection projects. They typically consist of multiple blocks laid on the slope surface, forming a continuous slope protection layer through the self-weight of the blocks, the jointing between adjacent blocks, and necessary anchoring structures. This layer resists slope erosion, water flow impact, and the loss of surface soil. Some ecological slope protection blocks also include planting areas for filling with planting substrate and planting slope protection vegetation, thus combining slope protection with ecological restoration functions.

[0003] Existing ecological slope protection blocks can generally be spliced ​​together by structures such as connecting grooves, snap-fit ​​parts, and limiting holes, or adjacent blocks can be connected and limited by block connectors. If necessary, nails, anchor rods, embedded parts, or grouting structures can be used to further fix the blocks to the slope to improve the blocks' resistance to sliding and erosion.

[0004] However, existing ecological slope protection blocks and their connecting structures still have the following problems:

[0005] 1. Existing block connectors are usually mainly used to limit the relative displacement between adjacent blocks, and they do not have the function of expanding anchorage into the slope soil. When the surface soil of the slope is softened and loosened by rainfall, water level fluctuations or water erosion, the fixing effect of relying solely on the self-weight of the blocks, splicing limit or conventional anchors is easily reduced.

[0006] 2. After the blocks are laid, the exchange path between the soil under the blocks and the outside air is relatively limited; in a long-term humid environment, the soil pores are easily occupied by water, and the permeability near the plant root zone is insufficient, which affects the growth of the root system of the slope protection plants.

[0007] 3. Rainfall or slope runoff tends to flow downwards along the surface of the blocks, the gaps between the blocks, or the surface of the planting area. When the local water flow is concentrated, it can easily cause the loss of the planting substrate. At the same time, if ventilation or drainage channels are set in the soil contact area, these channels are easily blocked by mud, fine particles, or roots.

[0008] Therefore, there is still room for improvement in existing ecological slope protection block connectors. In particular, there is a need for an ecological slope protection block connector that can connect and limit adjacent blocks while simultaneously achieving expansion anchoring within the slope soil, aeration of the soil beneath the blocks, dispersion and infiltration of water on the slope surface, and prevention of duct blockage. Summary of the Invention

[0009] The purpose of this invention is to provide an ecological slope protection block connector and an ecological slope protection system to solve the problems mentioned in the background art.

[0010] This invention is achieved through the following technical solution:

[0011] On the one hand, the present invention proposes an ecological slope protection block connector, including a connector body, a hollow tube body, and a pressure-expanding ventilated anchoring component;

[0012] The side wall of the connector body has at least two connecting ends, and the bottom surface of the connector body is provided with a plug-in part. The plug-in part is provided with a plug hole that penetrates the connector body, and the compression-expansion venting anchoring assembly is slidably disposed in the plug hole.

[0013] The bottom of the plug is connected to a limiting ring by a plurality of brackets spaced apart circumferentially, and a window is formed between adjacent brackets. The top surface of the limiting ring is provided with a tapered guide surface that gradually decreases from the inner circle to the outer circle of the limiting ring.

[0014] The pressure-expansion ventilation anchoring assembly includes a hollow central seat and multiple hollow legs connected to the lower part of the hollow central seat. A central cavity is formed inside the hollow central seat, and a leg cavity is formed inside the hollow leg that communicates with the central cavity. An air outlet and water outlet hole is opened on the hollow leg that communicates with the leg cavity.

[0015] The hollow tube is inserted into the insertion hole and can press down on the hollow center seat along the insertion hole. The hollow tube forms a cavity that communicates with the central cavity.

[0016] When the pressure-expansion ventilation anchoring assembly moves downward to the limiting ring under the action of the hollow tube, the multiple hollow legs switch from the retracted state to the expanded state under the guidance of the conical guide surface. The expanded hollow legs extend out through the window to the outside of the insertion part to insert into the slope soil.

[0017] Optionally, the bottom of the hollow tube is provided with a pressure surface, which is used to press the hollow center seat to move downward along the insertion hole. The limiting ring is used to limit the hollow center seat when the hollow tube presses down on the hollow center seat, so as to prevent the hollow center seat from coming out of the lower end of the insertion hole.

[0018] Optionally, the number of hollow legs corresponds to the number of windows, and each window is used for at least one hollow leg to extend outward; the windows are distributed circumferentially along the insertion part so that multiple hollow legs can be inserted into the slope soil in different directions after expansion.

[0019] Optionally, the upper opening of the hollow tube is provided with an anti-clogging cover, which is provided with filter holes, filter screen or sand-proof and breathable layer to allow outside air and some slope water to enter the tube cavity, and to block mud, fallen leaves or debris from entering the tube cavity.

[0020] Optionally, the outer wall of the hollow support leg is provided with a long strip-shaped elastic cover that covers the air outlet and water outlet. The long strip-shaped elastic cover has a connecting part that connects to the hollow support leg and a free end that is disposed opposite to the connecting part. The connecting part is located above the free end.

[0021] During the process of the hollow support leg expanding and inserting into the slope soil, the free end is blocked by the soil, causing the long strip elastic cover to arch in a restricted manner. An opening channel is formed between the long strip elastic cover and the outer wall of the hollow support leg, connecting the air and water outlet holes with the external soil.

[0022] Optionally, the elongated elastic cover is formed by a slit cut in the leg wall of the hollow leg, and slits are formed between the two sides of the elongated elastic cover and the leg wall of the hollow leg. The upper end of the elongated elastic cover is integrally connected to the leg wall of the hollow leg to form the connecting part, and the lower end of the elongated elastic cover forms the downward-facing free end.

[0023] Optionally, the outer wall of the hollow support leg is provided with a recessed mounting area, the air outlet and water outlet are opened in the recessed mounting area, and the elongated elastic cover covers the outside of the recessed mounting area.

[0024] When the elongated elastic cover is confined and arched, the opening channel is formed between the elongated elastic cover and the recessed mounting area.

[0025] Optionally, the outer surface of the elongated elastic cover is roughened to increase the friction between the elongated elastic cover and the surrounding soil.

[0026] And / or, the free end of the elongated elastic cover is provided with a wedge-shaped trigger part, which is used to increase the jamming effect of the soil on the free end when the hollow support leg is inserted into the soil, so as to cause the elongated elastic cover to arch in a restricted manner.

[0027] On the other hand, the present invention also proposes an ecological slope protection method, including a slope body, multiple block bodies, and multiple ecological slope protection block connectors as described above; the block body has at least two connecting mating parts, the multiple block bodies are laid on the surface of the slope body, the block body is provided with a planting area, and adjacent block bodies are connected and limited by the connecting end of the ecological slope protection block connector and the connecting mating part, and the multiple block bodies and the multiple ecological slope protection block connectors together form a mesh slope protection structure.

[0028] Optionally, the connecting end includes a snap-fit ​​part and a limiting step, and the connecting mating part is a connecting groove, snap-fit ​​groove, dovetail groove, T-groove, L-shaped snap-fit ​​groove or limiting hole opened on the side wall of the block body;

[0029] The snap-fit ​​part is used to enter the connecting and mating part of the block body, and the limiting step is used to abut against the side wall of the block body to restrict the block body from moving upward or coming out laterally relative to the ecological slope protection block connector.

[0030] Compared with the prior art, the present invention has at least the following beneficial effects:

[0031] 1. This invention features an insertion portion on the bottom surface of the connector body, and a pressure-expanding ventilated anchoring assembly that slides within the insertion hole of the insertion portion. Simultaneously, a pressure-expanding guide structure is formed by a bracket, a limiting ring, and a window. When the hollow central seat is pressed down, a conical guide surface guides multiple hollow legs from a retracted state to an expanded state, extending through the window to the outside of the insertion portion. Thus, the hollow legs can be inserted into the slope soil in multiple directions, forming a multi-directionally distributed expansion anchoring range, improving the overall stability of the connector and adjacent masonry blocks.

[0032] 2. The hollow tube body, hollow center seat, and hollow support legs of this invention are internally interconnected, and the hollow support legs are provided with air and water outlet holes. Outside air or some slope water can enter the hollow center seat through the hollow tube body, then enter the hollow support legs, and finally enter the slope soil through the air and water outlet holes. Therefore, the block connector not only serves a connecting and anchoring function but also forms a ventilation and drainage path extending into the slope soil, helping to improve the air permeability and moisture dispersion and infiltration effect of the soil beneath the blocks.

[0033] 3. When rainfall or slope runoff passes over the slope protection surface, some water can enter the slope soil through the air and water outlet holes of the hollow pipe, hollow center seat and multiple hollow legs, reducing the loss of planting substrate and local erosion of the slope caused by concentrated discharge of water along the surface of the block body, the gaps between the blocks body or the surface of the planting area.

[0034] 4. This invention features a long, elastic cover plate on the outer wall of the hollow outrigger, covering the air and water outlet holes. When the hollow outrigger expands and inserts into the slope soil, the free end of the long, elastic cover plate is obstructed by the soil, causing a restricted arch that creates an opening channel between the long, elastic cover plate and the outer wall of the hollow outrigger. This opening channel prevents soil from directly pressing against the air and water outlet holes, reducing the possibility of the air and water outlet holes being directly blocked by soil or fine particles after the hollow outrigger is inserted into the soil.

[0035] 5. The elongated elastic cover of the present invention forms a relatively controlled opening channel after being confined and arched. This opening channel allows air or water to flow out from the air and water outlet holes, while restricting large particles of mud, planting substrate, or roots from directly entering the support leg cavity. Thus, while ensuring the air and water channels remain connected, the risk of blockage caused by mud recharge and root intrusion is reduced, making the ventilation and drainage function of the hollow support leg more stable.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example: Figures 1 to 5As shown, this embodiment provides an ecological slope protection block connector, which is used to connect and limit adjacent block bodies 1. The block body 1 can be laid on the surface of the slope 8. A planting area 11 is provided on the block body 1, which is used to fill the planting substrate and plant slope protection plants. A connecting mating part 12 is also provided on the block body 1, which is used to cooperate with the ecological slope protection block connector to limit the relative displacement between adjacent block bodies 1.

[0044] The ecological slope protection block connector of this embodiment includes a connector body 2, a hollow tube body 3, and a pressure-expanding ventilation anchoring assembly 4. The side wall of the connector body 2 has at least two oppositely arranged connection ends 21, which are used to connect and cooperate with the connection mating parts 12 on the adjacent block body 1.

[0045] The bottom surface of the connector body 2 is provided with a plug-in portion 22, which faces the slope 8. A plug-in hole 23 is provided on the plug-in portion 22, extending vertically through the connector body 2. The expansion and ventilation anchoring assembly 4 is circumferentially fixed and axially slidable within the plug-in hole 23, allowing it to move up and down along the plug-in hole 23. When it is necessary to restrict its circumferential rotation, a guide key and a guide groove can be provided between the hole wall of the plug-in hole 23 and the outer wall of the hollow center seat 41, allowing the expansion and ventilation anchoring assembly 4 to move up and down along the plug-in hole 23 while restricting its circumferential rotation.

[0046] The bottom of the insertion part 22 is connected to a limiting ring 25 via multiple brackets 24 spaced circumferentially, forming a window 26 between adjacent brackets 24. The window 26 allows the hollow outrigger 42 to extend outward in the expanded state. The top surface of the limiting ring 25 is provided with a tapered guide surface 251 that gradually decreases from the inner ring to the outer ring. This tapered guide surface 251 is used to obliquely guide the hollow outrigger 42 when the compression-expansion ventilating anchor assembly 4 moves downward, so that the hollow outrigger 42 switches from the retracted state to the expanded state.

[0047] The compression-expansion ventilated anchoring assembly 4 includes a hollow central seat 41 and multiple hollow support legs 42 connected to the lower part of the hollow central seat 41. A central cavity 411 is formed inside the hollow central seat 41, and support legs 421 are formed inside the hollow support legs 42, which communicate with the central cavity 411. Air and water outlet holes 422 are provided on the hollow support legs 42, communicating with the support legs 421. Multiple hollow support legs 42 are spaced apart circumferentially along the hollow central seat 41. The hollow support legs 42 can be connected to the hollow central seat 41 through elastic bending parts, weak connection parts, or hinged structures, allowing the hollow support legs 42 to switch between a retracted state and an expanded state.

[0048] The hollow tube 3 is inserted into the insertion hole 23 and can be pressed downward along the insertion hole 23. A cavity 31 is formed inside the hollow tube 3, which communicates with the central cavity 411 of the hollow central seat 41. A pressing surface 32 is provided at the bottom of the hollow tube 3. The pressing surface 32 is used to press against the hollow central seat 41 when the hollow tube 3 is pressed downward, causing the hollow central seat 41 to move downward along the insertion hole 23. The pressing surface 32 can be the end face of the bottom of the hollow tube 3, an annular step surface, or a flange surface, as long as it can press against the hollow central seat 41 and push it downward. The upper end of the tapered guide surface 251 has a through hole 252 communicating with the central cavity 411, so that after the hollow central seat 41 is pressed into place, the bottom of the insertion part 22 communicates with the central cavity 411.

[0049] When the hollow tube 3 is pressed downwards, the pressing surface 32 presses against the hollow center seat 41, causing the expansion and ventilation anchoring assembly 4 to move downwards along the insertion hole 23. When the hollow center seat 41 moves to the limiting ring 25, the limiting ring 25 engages with the hollow center seat 41 to prevent the hollow center seat 41 from dislodging from the lower end of the insertion hole 23. At this time, the hollow support leg 42 abuts against the conical guide surface 251 on the top surface of the limiting ring 25, and switches from a retracted state to an expanded state under the guidance of the conical guide surface 251. The expanded hollow support leg 42 extends out through the window 26 between adjacent supports 24 to the outside of the insertion part 22 and is inserted into the soil of the slope 8.

[0050] Therefore, the ecological slope protection block connector of this embodiment can connect and limit the adjacent block body 1 through the connecting end 21, and can also form a multi-directional expansion anchoring structure in the soil of the slope 8 through the hollow support leg 42, thereby improving the overall stability of the connector and the adjacent block body 1.

[0051] Furthermore, the number of hollow outriggers 42 corresponds to the number of windows 26, with each window 26 allowing at least one hollow outrigger 42 to extend outward. Multiple windows 26 are spaced apart circumferentially along the insertion portion 22, enabling multiple hollow outriggers 42 to be inserted into the soil of the slope 8 in different directions after expansion, thereby increasing the range of expansion anchoring.

[0052] A clogging-proof cover 33 may be installed at the upper opening of the hollow tube body 3. The clogging-proof cover 33 is provided with filter holes, filter screen or sand-proof and breathable layer to allow outside air and some slope water to enter the tube cavity 31, while blocking mud, fallen leaves and debris from entering the tube cavity 31. The clogging-proof cover 33 can be integrally formed with the hollow tube body 3, or it can be detachably installed on the upper end of the hollow tube body 3 for cleaning or replacement.

[0053] During use, outside air or some slope water can enter the cavity 31 of the hollow tube 3 through the anti-blocking cover 33, then enter the central cavity 411 of the hollow central seat 41 and the leg cavity 421 of the hollow support leg 42, and enter the soil of the slope 8 through the air and water outlet holes 422 on the hollow support leg 42. Thus, the ecological slope protection block connector not only undertakes the functions of connection and anchoring, but also forms a ventilation and drainage path that extends into the soil of the slope 8, which helps to improve the permeability of the soil below the block body 1 and allows some slope water to disperse into the soil.

[0054] Based on the above embodiment, the outer wall of the hollow support leg 42 is provided with a long strip-shaped elastic cover 43 covering the air and water outlet holes 422. The long strip-shaped elastic cover 43 has a connecting part 431 connected to the hollow support leg 42 and a free end 432 disposed opposite to the connecting part 431, with the connecting part 431 located above the free end 432. During the process of the hollow support leg 42 expanding and inserting into the soil of the slope 8, the free end 432 is blocked by the soil, causing the long strip-shaped elastic cover 43 to arch in a restricted manner, forming an opening channel 433 between the long strip-shaped elastic cover 43 and the outer wall of the hollow support leg 42, connecting the air and water outlet holes 422 and the external soil.

[0055] Specifically, the elongated elastic cover 43 can be formed by slits in the leg wall of the hollow leg 42. Two lateral slits extending along the length of the leg and a transverse slit communicating with the lower ends of the two lateral slits are provided on the leg wall of the hollow leg 42, so that the cut leg wall area forms the elongated elastic cover 43. The upper end of the elongated elastic cover 43 is not cut off and is integrally connected to the leg wall of the hollow leg 42 to form a connecting portion 431; the lower end of the elongated elastic cover 43 is cut open to form a downward-facing free end 432.

[0056] Because the free end 432 is positioned downwards, as the hollow support leg 42 expands outwards and inserts into the soil of the slope 8, the soil will obstruct the free end 432, causing the elongated elastic cover 43 to arch in a restricted manner. This restricted arching of the elongated elastic cover 43 and the outer wall of the hollow support leg 42 forms an opening channel 433, making it less likely for soil to directly press against the opening of the air and water outlet holes 422, thus reducing the possibility of the air and water outlet holes 422 being directly blocked by soil or fine particles.

[0057] Furthermore, the outer wall of the hollow support leg 42 may be provided with a recessed installation area 423, with air and water outlet holes 422 formed within the recessed installation area 423, and a long strip-shaped elastic cover 43 covering the outside of the recessed installation area 423. When the long strip-shaped elastic cover 43 is restricted from arching, an opening channel 433 is formed between the long strip-shaped elastic cover 43 and the recessed installation area 423. By providing the recessed installation area 423, the arching space of the long strip-shaped elastic cover 43 can be restricted, reducing its excessive disturbance to the surrounding soil, while ensuring a stable air and water flow space outside the air and water outlet holes 422.

[0058] The outer surface of the elongated elastic cover plate 43 can be roughened to increase the friction between the elongated elastic cover plate 43 and the surrounding soil. The free end 432 of the elongated elastic cover plate 43 can also be provided with a wedge-shaped trigger part 434 to guide the soil to act on the free end 432 when the hollow support leg 42 is inserted into the soil, so as to cause the elongated elastic cover plate 43 to arch in a restricted manner.

[0059] In this embodiment, the elongated elastic cover 43 does not keep the air and water outlets 422 completely open for extended periods. Instead, it arches up during the insertion of the hollow support leg 42 into the soil, forming a relatively controlled opening channel 433. This opening channel 433 allows air or water to flow out of the air and water outlets 422 while restricting large particles of silt, planting substrate, or roots from directly entering the support leg cavity 421, thereby reducing the risk of silt recharge and root intrusion causing blockage.

[0060] Based on the above embodiments, this embodiment provides an ecological slope protection, including a slope body 8, multiple block bodies 1, and multiple ecological slope protection block connectors as described above.

[0061] Multiple block bodies 1 are laid on the surface of the slope 8. Planting areas 11 are provided on the block bodies 1. The planting areas 11 are used to fill the planting substrate and plant slope protection plants. The block bodies 1 have at least two connecting parts 12. Adjacent block bodies 1 are connected and limited by the connecting end 21 of the ecological slope protection block connector to the connecting parts 12. Multiple block bodies 1 and multiple ecological slope protection block connectors together form a mesh slope protection structure.

[0062] The connecting end 21 may include a snap-fit ​​portion 211 and a limiting step 212. The connecting mating portion 12 may be a connecting groove, snap-fit ​​groove, dovetail groove, T-groove, L-shaped snap-fit ​​groove, or limiting hole formed on the side wall of the block body 1. The snap-fit ​​portion 211 is used to enter the connecting mating portion 12 of the block body 1, and the limiting step 212 is used to abut against the side wall of the block body 1 to limit the block body 1 from moving upward or disengaging laterally relative to the ecological slope protection block connector.

[0063] During construction, multiple block bodies 1 are first laid on the surface of the slope 8. Then, the connecting end 21 of the ecological slope protection block connector is engaged with the connecting mating part 12 of the adjacent block body 1, so that the adjacent block bodies 1 are connected and limited. Subsequently, the hollow tube 3 is pressed down along the insertion hole 23, so that the hollow tube 3 presses against the hollow center seat 41 and drives the pressure expansion and ventilation anchoring component 4 to move down. The hollow support leg 42 switches from the retracted state to the expanded state under the action of the conical guide surface 251 of the limiting ring 25, and extends out through the window 26 to the outside of the insertion part 22, and is inserted into the soil of the slope 8.

[0064] After installation, the ecological slope protection block connectors connect and limit adjacent block bodies 1 through the connecting end 21, and anchor the expanded hollow support legs 42 to the slope 8 soil. Outside air or some slope surface water can enter the hollow center seat 41 and hollow support legs 42 through the hollow tube 3, and then disperse into the slope 8 soil through the air and water outlet holes 422. If the hollow support legs 42 are equipped with long, elastic covers 43, air or water can also enter the surrounding soil through the opening channel 433.

[0065] In other embodiments, the connector body 2 can be configured as a rod-shaped, cross-shaped, T-shaped, I-shaped or other structure according to the arrangement of the block body 1; the connector end 21 can be inserted, snapped, pressed or slidably engaged with the connector mating part 12.

[0066] In other embodiments, the hollow support leg 42 can be an elastic support leg or a hinged support leg; the number of hollow support legs 42 can be three, four, six or more. The number of windows 26 can be the same as the number of hollow support legs 42, or one window 26 can correspond to multiple hollow support legs 42.

[0067] In other embodiments, the air outlet and water outlet 422 can be a round hole, an elongated hole, a slit hole, or a group of holes. A strip-shaped elastic cover 43 can cover one air outlet and water outlet 422 or a group of air outlet and water outlets 422.

[0068] In other embodiments, the pressure-expanding ventilating anchoring assembly 4 can be made of metal, engineering plastics, glass fiber reinforced composite materials, or corrosion-resistant elastic materials. The lower end of the hollow tube 3 and the hollow center seat 41 can be connected by a plug-in, abutment, or sleeve structure, as long as it can press the hollow center seat 41 downward during the pressing of the hollow tube 3 and connect the tube cavity 31 with the center cavity 411 after installation.
