Description

Technical Field

[0001] This application relates to the field of soil and water conservation technology, and more specifically, to slope protection devices. Background Technology

[0002] During the construction of highways in high-altitude and cold regions, a large number of shallow rock and soil masses are often encountered. In recent years, with the gradual expansion of highway construction in plateau areas, strong frost weathering has led to frequent geological disasters along the highways.

[0003] Due to their unique climatic conditions, high-altitude and cold regions experience large temperature differences between day and night. Under the action of freeze-thaw cycles, the expansion of water freezing in winter causes the cracks in the soil and rock to widen. After thawing in spring, the soil becomes saturated and softened, increasing its self-weight and easily forming a "rubble pile" structure. This significantly reduces the shear strength of the soil and rock, making shallow landslides in high-altitude and cold regions prone to various diseases. These diseases not only affect the stability of the slope and the ecological environment, but may also pose a threat to the surrounding infrastructure and human activities.

[0004] However, existing slope protection devices are used outdoors year-round, which can easily reduce their service life and pose safety hazards. Utility Model Content

[0005] The purpose of this application is to provide a slope protection device with a long service life.

[0006] To achieve the above objectives, this utility model provides a slope protection device, comprising:

[0007] The slope protection net includes fixed piles, guy ropes, and slope protection vegetation. The guy ropes are arranged in a grid structure to cover the slope soil. The fixed piles are set at the nodes of the grid structure formed by the guy ropes. One end of the fixed pile is fixed in the slope soil, and the other end of the fixed pile is connected to the node of the grid structure. The slope protection vegetation is set in the grid of the grid structure.

[0008] The fixed pile includes a pile body and a protective layer covering the pile body.

[0009] In an optional embodiment, the protective layer is an asphalt coating.

[0010] In an optional embodiment, a drainage ditch is also included, which is disposed on the slope and above the slope protection net, and is used to block water flowing from above the slope to the slope protection net.

[0011] In an optional embodiment, the fixed pile body is divided into an driven section driven into the slope and an exposed section located outside the slope soil, wherein the ratio of the length L of the driven section to the length M of the exposed section is R, where 5≤R≤7.

[0012] In an optional embodiment, the fixed pile body is divided into an driven section driven into the slope and an exposed section located outside the slope soil.

[0013] The fixed stake has a through hole for the pull rope to pass through, and the through hole is located at the connection between the driven section and the exposed section.

[0014] In an optional embodiment, the pull rope includes a horizontal rope, a first inclined rope inclined in one direction relative to the horizontal rope, and a second inclined rope inclined in another direction relative to the horizontal rope, the horizontal rope, the first inclined rope and the second inclined rope defining the triangular grid of the mesh structure.

[0015] In an optional embodiment, a fastener for securing the end of the pull rope is also included.

[0016] In an optional embodiment, a tensioning member is further included for tensioning the rope. The tensioning member includes a spool for winding the end of the rope and a mounting base for providing a mounting foundation for the spool. The mounting base is mounted on the fixed stake, and the spool is rotatably mounted on the mounting base. Rotating the spool in the forward direction causes the rope to wind around the spool to tension the rope.

[0017] In an optional embodiment, the tensioning member further includes a ratchet mechanism for preventing the spool from rotating in the reverse direction. The ratchet mechanism includes a ratchet gear sleeved on the spool and a stop block rotatably mounted on the mounting base. The ratchet gear is fixedly connected to the spool, and the stop block is used to prevent the ratchet gear from rotating in the reverse direction.

[0018] In an optional embodiment, the tensioner further includes a handle for driving the spool to rotate, the handle being detachably connected to the spool.

[0019] In this application, the fixed piles secure the grid-like structure formed by the guy ropes to the slope, and the protective layer surrounding the fixed piles enhances their strength. During slope protection, the fixed piles must withstand the tension of the guy ropes and the pressure of the slope soil. Stronger fixed piles better resist these external forces, are less prone to breakage or deformation, and thus ensure the stability and reliability of the slope protection net. The protective layer also reduces corrosion and sun exposure to the fixed piles. Slope environments are typically complex, and fixed piles exposed to air for extended periods are susceptible to corrosion and aging due to rain, humidity, and ultraviolet radiation. The protective layer effectively blocks these harmful factors, extends the service life of the fixed piles, and reduces maintenance costs.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Embodiments of this application provide a slope protection device for slope protection; such as Figure 1 As shown, the slope protection device includes a slope protection net 100, which is installed on the slope.

[0034] like Figure 1 As shown, the slope protection net 100 includes fixed piles 110, guy ropes 120 and slope protection vegetation 130. The guy ropes 120 are set in a grid structure to cover the slope soil. Fixed piles 110 are set at the nodes of the grid structure formed by the guy ropes 120. The fixed piles 110 are used to fix the guy ropes 120 on the slope.

[0035] The slope protection net 100 is fixed to the slope soil by fixing piles 110, and the ropes 120 are set into a grid structure to cover the slope soil, with fixing piles 110 set at the grid nodes for connection and fixation. This structure can form an integrated protection system, effectively wrapping and restraining the slope soil, enhancing the integrity and stability of the slope soil, reducing the risk of slope soil slippage and collapse, and providing reliable protection for the slope.

[0036] One end of the fixed pile 110 is fixed in the slope soil, and the other end of the fixed pile 110 is connected to the nodes of the grid structure; the grid structure formed by the ropes 120 is used to fix the slope soil. For example, the number and location of the nodes of the grid structure formed by the ropes 120 are matched with the number and location of the fixed piles 110.

[0037] The grid-like structure contains slope protection vegetation 130. The root system of the slope protection vegetation 130 can penetrate deep into the slope soil, playing a role in soil stabilization and further enhancing the stability of the slope soil. At the same time, the growth of the vegetation can also cover the slope surface, reducing rainwater erosion of the slope soil and lowering the risk of soil erosion.

[0038] like Figure 2 and Figure 3 As shown, the fixed pile 110 includes a pile body and a protective layer covering the pile body. The pile body is, for example, a wooden pile or a metal pile; the wooden pile is, for example, a pine wood pile, and the metal pile is, for example, a steel reinforcement pile.

[0039] The protective layer can improve the strength of the fixed piles 110. During the slope protection process, the fixed piles 110 need to withstand the tension of the ropes 120 and the pressure of the slope soil. The stronger fixed piles 110 can better resist these external forces and are less likely to break or deform, thereby ensuring the stability and reliability of the slope protection net 100.

[0040] The protective layer also reduces the corrosion and sun exposure of the fixed piles 110. Slope environments are typically complex, and the fixed piles 110, exposed to air for extended periods, are susceptible to corrosion and aging due to rainwater, humidity, and ultraviolet radiation. The protective layer effectively blocks these harmful factors, extending the service life of the fixed piles 110 and reducing maintenance costs.

[0041] like Figure 3 As shown, in one embodiment, the protective layer is an asphalt coating 116.

[0042] For example, the protective layer on the pile body of the fixed pile 110 can be achieved by applying asphalt or hot-dip asphalt.

[0043] Asphalt possesses chemical stability and can form a dense protective film on the surface of the fixed pile 110, effectively isolating the pile from direct contact with air, moisture, and corrosive substances in the soil. For example, in a damp slope environment, the soil may contain various salts and acidic substances, which can accelerate the corrosion of the metal pile. The asphalt coating 116 can prevent these substances from reacting chemically with the pile, thereby greatly extending the service life of the fixed pile 110 and reducing the problems of reduced pile strength and structural damage caused by corrosion.

[0044] Prolonged exposure to sunlight will cause the pile material to age due to ultraviolet radiation, resulting in reduced strength and increased brittleness. The asphalt coating 116 can absorb or reflect some ultraviolet rays, reducing direct damage to the pile and slowing down the aging process, allowing it to maintain good performance in outdoor environments for a long time.

[0045] like Figure 1As shown, in one embodiment, the slope protection device further includes a drainage ditch 300, which is disposed on the slope and above the slope protection net 100. The drainage ditch 300 is used to block the flow of water above the slope to the slope protection net 100.

[0046] Highways typically have slopes along their sides. During rainy weather, rainwater flows from the highway towards these slopes. Without the drainage ditch 300 to block it, the rainwater would directly erode the slope soil. Continuous erosion by rainwater can cause soil loss, leading to gullies on the slope surface and even triggering geological disasters such as landslides. The drainage ditch 300, located on the slope and above the retaining net 100, effectively prevents water from flowing from above the slope towards the retaining net 100, avoiding direct impact of rainwater on the slope soil, thus reducing soil erosion and maintaining slope stability.

[0047] like Figure 3 As shown, in one embodiment, the pile body of the fixed pile 110 is divided into a driven section 112 driven into the slope and an exposed section 114 located outside the slope soil. The ratio of the length L of the driven section 112 to the length M of the exposed section 114 is R, where 5≤R≤7.

[0048] The driven section 112 is the part of the fixed pile 110 that penetrates deep into the slope soil. Its length directly affects the friction and anchoring force between the fixed pile 110 and the soil. When the ratio R of the length of the driven section 112 to the exposed section 114 is between 5 and 7, it means that the driven section 112 has sufficient length to penetrate into the slope soil, thereby generating sufficient friction and anchoring force, making the fixed pile 110 more stable in the slope soil, less likely to be pulled out or loosened by external forces, and effectively resisting the sliding force of the slope soil and other external forces. If the ratio R is less than 5, the fixed pile 110 has insufficient friction and is easily pulled out, and the anchoring force to the slope soil is also insufficient, making the slope prone to collapse. If the ratio R is greater than 7, the fixed pile 110 is difficult to drive in, affecting construction efficiency. If the fixed pile 110 is driven in with excessive force, it is easy to cause the fixed pile 110 to bend and deform, affecting the anchoring effect.

[0049] Furthermore, when the ratio R of the length of the driven section 112 to the exposed section 114 is between 5 and 7, the fixed pile 110 can adapt to various soil conditions to a certain extent without repeated verification. In looser soil, the longer driven section 112 can penetrate into relatively stable soil layers, providing reliable anchorage; in harder soil, the appropriate length of the driven section 112 can also ensure sufficient interlocking force and friction between the fixed pile 110 and the soil, ensuring the stability of the fixed pile 110.

[0050] For example, the length of the inserted segment 112 is L = 50 cm, the length of the exposed segment 114 is M = 10 cm, and R = L / M = 5. In another embodiment, the length of the inserted segment 112 is L = 60 cm, the length of the exposed segment 114 is M = 10 cm, and R = L / M = 6. In yet another embodiment, the length of the inserted segment 112 is L = 70 cm, the length of the exposed segment 114 is M = 10 cm, and R = L / M = 7.

[0051] like Figure 3 As shown, in one embodiment, the fixed pile 110 has a through hole for the pull rope 120 to pass through. The through hole is located at the connection between the driven section 112 and the exposed section 114, so that the pull rope 120 is tightly attached to the surface of the slope soil, improving the binding capacity of the slope soil and effectively limiting the movement and slippage of the soil. When the slope is eroded by rainwater, the pull rope 120 can prevent the displacement of soil particles in different directions, reduce local loosening and loss of soil, thereby expanding the protection range of the slope soil and improving the overall protection effect of the slope.

[0052] If there is a gap between the guy rope 120 and the slope, the guy rope 120 is prone to swaying when exposed to wind. However, keeping the guy rope 120 close to the slope surface significantly reduces its wind-exposed area. When the guy rope 120 is parallel to the slope and in close contact, the force exerted by the wind on the guy rope 120 decreases, thereby reducing the amplitude and frequency of its swaying in the wind. This helps maintain the stable structure of the slope protection net 100 and prevents a decline in the overall performance of the slope protection net 100 due to excessive swaying of the guy rope 120. The guy rope 120 generates friction after contacting the slope soil, which further limits its swaying. When the guy rope 120 is subjected to an external force attempting to sway, the friction hinders its movement, keeping the guy rope 120 in a relatively stable position. Compared to the guy rope 120 being suspended in the air, the guy rope 120 with friction limiting it can better resist external disturbances and reduce the impact of swaying on the slope protection system.

[0053] When the guy rope 120 sways, it easily rubs against the slope vegetation 130 and the slope itself. Long-term friction causes wear on the surface of the guy rope 120, reducing its strength and service life. However, when the guy rope 120 is pressed tightly against the slope surface, swaying is reduced, and contact and friction with the slope vegetation 130 are correspondingly reduced. This effectively protects the guy rope 120, extends its service life, and reduces maintenance costs.

[0054] like Figure 1 and Figure 2As shown, in one embodiment, the tension rope 120 includes a horizontal rope 122, a first inclined rope 124 inclined in one direction relative to the horizontal rope 122, and a second inclined rope 126 inclined in another direction relative to the horizontal rope 122. The horizontal rope 122, the first inclined rope 124, and the second inclined rope 126 define a triangular grid of a mesh-like structure. When the slope is subjected to external forces, these forces are evenly distributed across each triangular grid. Due to the stability of the triangular grid, the forces are transmitted and balanced within the grid through the tension of the ropes, preventing the horizontal rope 122, the first inclined rope 124, or the second inclined rope 126 from breaking under individual stress.

[0055] like Figure 2 As shown, in one embodiment, the slope protection device further includes a fastener 400 for securing the end of the pull rope 120.

[0056] For example, the fastener 400 is provided on the fixing post 110 located at the edge of the slope protection net 100. Since the end of the pull rope 120 is provided on the fixing post 110 located at the edge of the slope protection net 100, the fastener 400 can fix the end of the pull rope 120 to the fixing post 110.

[0057] For example, the fastener 400 includes a screw 410 and a pressure block 420. One end of the screw 410 is threaded onto the fixing post 110. The pressure block 420 is provided with a threaded through hole. The pressure block 420 is threadedly engaged with the other end of the screw 410 through the threaded through hole. During forward rotation, the pressure block 420 can approach the fixing post 110 along the axial direction of the screw 410 on the thread. The end of the pull rope 120 (e.g., a horizontal rope 122) is placed between the pressure block 420 and the fixing post 110. By rotating the pressure block 420 forward, the pressure block 420 moves closer to the fixing post 110, thereby pressing and fixing the end of the pull rope 120 onto the fixing post 110.

[0058] like Figure 2 As shown, in one embodiment, the slope protection device further includes a tensioning member 500 for tensioning the rope 120. The tensioning member 500 includes a reel 510 for winding around the end of the rope 120 and a mounting base 520 for providing a mounting foundation for the reel 510. The mounting base 520 is mounted on the fixed pile 110, and the fixing method is, for example, snap-fit ​​or bolt connection.

[0059] The spool 510 is rotatably mounted on the mounting base 520. Rotating the spool 510 in the forward direction causes the pull rope 120 to be wound around the spool 510 to tension the pull rope 120. Then, the end of the pull rope 120 is fixed to the fixing member 400.

[0060] like Figure 2As shown, in one embodiment, the tensioner 500 further includes a ratchet mechanism for preventing the reel 510 from rotating in the opposite direction. The ratchet mechanism includes a ratchet gear 530 sleeved on the reel 510 and a stop block 540 rotatably mounted on the mounting base 520.

[0061] The ratchet 530 is fixedly connected to the reel 510, for example by welding, snap-fitting, or bolting. The forward rotation of the ratchet 530 drives the reel 510 to rotate forward, thereby tensioning the pull rope 120.

[0062] The stop block 540 is used to stop the ratchet 530 from rotating in the opposite direction.

[0063] For example, one end of the stop block 540 is hinged to the mounting base 520, and the other end of the stop block 540 abuts against the ratchet 530. The forward rotation of the ratchet 530 will cause the stop block 540 to rotate in the forward direction, and the stop block 540 follows the forward rotation of the ratchet 530. Therefore, the stop block 540 does not obstruct the forward rotation of the ratchet 530.

[0064] The mounting base 520 is provided with a stop part, which is used to stop the stop block 540 from rotating in the opposite direction. The ratchet 530 rotates in the opposite direction, which drives the stop block 540 to rotate in the opposite direction. During the reverse rotation, the stop block 540 abuts against the stop part, and the stop part hinders the reverse rotation of the stop block 540, thereby hindering the reverse rotation of the ratchet 530 through the stop block 540.

[0065] The mounting base 520 is provided with an elastic element 550, which is used to drive the stop block 540 to reset.

[0066] In one embodiment, the tensioner 500 further includes a handle for driving the spool 510 to rotate, the handle being detachably connected to the spool 510.

[0067] For example, a hexagonal mating groove is provided on the end face of the spool 510, and a hexagonal mating protrusion is provided on the handle to mate with the hexagonal mating groove. The hexagonal mating protrusion is inserted into the hexagonal mating groove of the spool 510, and the handle is rotated, which drives the spool 510 to rotate.

[0068] In one embodiment, the pull cord 120 is supplemented with a UV-resistant additive to increase its service life. The UV-resistant additive may be, for example, a benzotriazole additive, a triazine additive, or a nano-titanium dioxide additive.

[0069] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
