Abstract
Description
Technical Field
[0001] This utility model relates to the field of embankment slope reinforcement structure, specifically an embankment slope reinforcement structure. Background Technology
[0002] An embankment is the fill portion of a roadbed that is higher than the original ground level. It is a common road cross-section in urban roads and highway engineering. Embankments can be double-sided (filled on both sides) or single-sided (filled on one side, with one side relying on higher ground). Regardless of the type, since the top of the roadbed is higher than the original ground level, slope protection measures are required to ensure the stability of the embankment. Commonly used embankment slope protection methods include hexagonal block topsoil and grass planting or topsoil and grass planting within a water-cutting framework. However, many highway and railway construction projects use sandy soil as fill for embankments. Sandy soil filler embankments have poor erosion resistance, and seepage water within the fill can easily carry away fine sand particles, affecting embankment slope stability, especially in areas with high rainfall intensity.
[0003] The existing devices have the following shortcomings when in use: the reinforcement structure set on the embankment slope is not stable enough as a whole, the reinforcement effect of the reinforcement structure on the embankment slope is not good, and it cannot maintain the stability of the embankment in the long term, which poses a threat to the safety and stability of the road. Utility Model Content
[0004] The purpose of this utility model is to provide a road embankment slope reinforcement structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a road embankment slope reinforcement structure, comprising a foundation rock layer, an embankment slope, a reinforcement channel, a conical groove, reinforcement bars, and a concrete reinforcement strip. The embankment slope extends inclinedly along the foundation rock layer, with the foundation rock layer located below the embankment slope. Multiple anchor holes are provided on the embankment slope, and anchor cables are installed in the anchor holes. The surface of the embankment slope is provided with a reinforcement channel, and a conical groove is provided at the bottom of the reinforcement channel. Reinforcing bars are placed in the reinforcement channel, and toothed protrusions are provided on the outer wall of the reinforcing bars. Concrete is poured into the reinforcement channel to form a concrete reinforcement strip.
[0006] Using the above technical solution, anchor holes are rationally drilled according to the area of the embankment slope. Anchor cables are inserted into the foundation rock layer through these holes, and concrete is poured into the anchor holes to form concrete anchorage, thus fixing the concrete anchorage to the foundation rock layer. The anchor cables are then connected to the slope reinforcement structure installed on the outside of the embankment slope, ensuring a tight bond between the slope reinforcement structure and the embankment slope, forming a stable whole. Reinforcement channels are drilled on the surface of the embankment slope, providing reliable placement space for reinforcing steel bars. After the reinforcing steel bars are placed, one end of the reinforcing steel bars is tightly connected to one end of the anchor cable with reinforcing bars, forming a robust grid system. Concrete is then poured into the reinforcement channels to form a concrete reinforcement strip. This concrete reinforcement strip not only fills the reinforcement channels but also tightly wraps the connection between the reinforcing steel bars and the anchor cables, greatly enhancing the overall stability of the structure. The design of the toothed protrusions on the reinforcing steel bars enhances stability and durability, effectively increasing the interlocking force between the reinforcing steel bars and concrete, preventing slippage of the reinforcing steel bars within the concrete, and further improving the slope reinforcement effect. The conical grooves on the reinforcement channels increase the friction between the concrete and the channels, making the connection between the concrete reinforcement strip and the channels more secure. This ensures that the concrete reinforcement strip adheres more firmly to the slope, preventing loosening or detachment, and preventing slope instability caused by soil loosening or water erosion. Multiple reinforcement structures are firmly fixed together, forming a robust and durable slope protection structure. This structure not only improves slope stability but also extends the service life of the road, enhances the structural stability of the embankment slope, and significantly improves its resistance to sliding and shearing.
[0007] Preferably, a topsoil and grass layer is formed between the concrete reinforcement strips, and hooks are provided on the four walls of the topsoil and grass layer. Protective wire mesh is fixedly installed on the hooks, and vegetation is planted on top of the topsoil and grass layer.
[0008] By adopting the above technical solution, the combination of hooks and protective wire mesh further stabilizes the topsoil and grass layer, prevents soil erosion, and provides support for vegetation growth. The planting of vegetation allows the roots to penetrate deep into the soil, forming a stable root network, preventing soil loss. This not only beautifies the slope landscape but also enhances the slope's soil retention capacity, further consolidating the slope's stability.
[0009] Preferably, concrete is poured into the anchor hole to form a concrete anchor that is fixedly connected to the foundation rock layer.
[0010] By employing the above technical solution, concrete is poured into the anchor hole to form a concrete anchor to the foundation rock layer. Then, the anchor structure is connected to the slope reinforcement structure set on the outside of the embankment slope. With its strong bonding force and tensile strength, the concrete anchor firmly locks the slope reinforcement structure set on the outside of the embankment slope to the embankment slope, making the entire slope fixing system more stable and durable.
[0011] Preferably, a drainage ditch is provided at the bottom of the embankment slope, and the inner wall surface of the drainage ditch is provided with a concrete slope.
[0012] By adopting the above technical solution, the drainage ditch can effectively guide rainwater or accumulated water to flow smoothly out, avoiding water erosion and damage to the embankment slope. The concrete slope not only enhances the structural strength of the drainage ditch, but also improves its weather resistance and durability, ensuring that the drainage ditch maintains good drainage function during long-term use.
[0013] Preferably, the reinforcing channels are arranged in a crisscross pattern and the intersection point is located at the concrete anchorage, and the reinforcing steel bars are tightly connected to one end of the anchor cable by steel bar binding.
[0014] By employing the above technical solution, a robust grid system is formed through the crisscrossing layout of the reinforcement channels. The intersection points are located at the concrete anchorages, facilitating the tight connection between the reinforcing bars and anchor cables, thus creating a strong grid system. This arrangement makes the entire structure more tightly connected and less susceptible to external impacts. The reinforcing bars are tightly connected to one end of the anchor cables via steel reinforcement, which not only enhances the connection strength between the bars and anchor cables but also further improves the shear and tensile strength of the slope reinforcement structure.
[0015] Preferably, the anchor cable, reinforcing steel bar, and protective wire mesh have all undergone special anti-corrosion treatment.
[0016] By adopting the above technical solutions, these components can maintain good performance in harsh environments, effectively resist corrosion and rust, and extend their service life. This anti-corrosion treatment not only improves the durability of individual components, but also ensures the long-term stability and reliability of the entire slope reinforcement system.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The toothed protrusion design on the reinforcing steel effectively increases the interlocking force between the reinforcing steel and the concrete, preventing the reinforcing steel from slipping in the concrete and further improving the slope reinforcement effect. The conical grooves set on the reinforcement channel increase the friction between the concrete and the reinforcement channel, making the connection between the concrete reinforcement strip and the reinforcement channel more secure. This makes the concrete reinforcement strip more firmly attached to the slope, less prone to loosening or falling off, preventing slope instability caused by soil loosening or water erosion. Multiple reinforcement structures are firmly fixed together to form a sturdy and durable slope protection structure. This structure not only improves the stability of the slope but also extends the service life of the road, enhances the structural stability of the embankment slope, and greatly improves its resistance to sliding and shearing.
[0019] 2. The combined use of hooks and protective wire mesh further stabilizes the topsoil and grass layer, preventing soil erosion. It also provides support for vegetation growth. The planting of vegetation allows the roots to penetrate deep into the soil, forming a stable root network that prevents soil loss. This not only beautifies the slope landscape but also enhances the slope's soil retention capacity, further consolidating its stability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figure 1-4This utility model provides an embodiment of an embankment slope reinforcement structure, comprising a foundation rock layer 1, an embankment slope 2, a reinforcement channel 6, a conical groove 7, reinforcing steel bars 8, and a concrete reinforcement strip 9. The embankment slope 2 extends obliquely along the foundation rock layer 1, with the foundation rock layer 1 located below the embankment slope 2. Multiple anchor holes 3 are provided on the embankment slope 2, and anchor cables 4 are installed in the anchor holes 3. The surface of the embankment slope 2 is provided with a reinforcement channel 6, and a conical groove 7 is provided at the bottom of the reinforcement channel 6. Reinforcing steel bars 8 are placed in the reinforcement channel 6, and toothed protrusions 11 are provided on the outer wall of the reinforcing steel bars 8. Concrete is poured into the reinforcement channel 6 to form a concrete reinforcement strip 9. Anchor holes 3 are rationally constructed according to the area of the embankment slope 2. Anchor cables 4 are inserted into the foundation rock layer 1 through the anchor holes 3. Concrete is poured into the anchor holes 3 to form concrete anchors 5, which are then fixedly connected to the foundation rock layer 1. The anchor cables 4 are then connected to the slope reinforcement structure set on the outside of the embankment slope 2, ensuring a tight bond between the slope reinforcement structure and the embankment slope 2, forming a stable whole. Reinforcement channels 6 are opened on the surface of the embankment slope 2 to provide reliable placement space for the reinforcing steel bars 8. After the reinforcing steel bars 8 are placed, one end of the reinforcing steel bars 8 is tightly connected to one end of the anchor cable 4 with steel bars to form a strong grid system. Then, concrete is poured into the reinforcement channels 6 to form a concrete reinforcement strip 9. The concrete reinforcement strip 9 not only fills the reinforcement channels 6 but also tightly wraps the connection between the reinforcing steel bars 8 and the anchor cables 4, greatly enhancing the overall structure. The toothed protrusions 11 on the reinforcing steel bar 8 enhance the stability and durability of the slope. This design effectively increases the interlocking force between the reinforcing steel bar 8 and the concrete, preventing the reinforcing steel bar 8 from slipping in the concrete and further improving the slope reinforcement effect. The conical grooves 7 on the reinforcing channel 6 increase the friction between the concrete and the reinforcing channel 6, making the connection between the concrete reinforcing strip 9 and the reinforcing channel 6 more secure. This allows the concrete reinforcing strip 9 to adhere more firmly to the slope, making it less prone to loosening or falling off. This prevents slope instability caused by soil loosening or water erosion. Multiple reinforcement structures are firmly fixed together, forming a robust and durable slope protection structure. This structure not only improves the stability of the slope but also extends the service life of the road, enhances the structural stability of the embankment slope, and greatly improves its resistance to sliding and shearing.
[0027] A topsoil and grass layer 10 is formed between the concrete reinforcement strips 9. Hooks 12 are installed on the four walls of the topsoil and grass layer 10, and protective wire mesh 13 is fixedly installed on the hooks 12. Vegetation is planted on top of the topsoil and grass layer 10. The combined use of hooks 12 and protective wire mesh 13 further stabilizes the topsoil and grass layer 10, prevents soil erosion, and provides support for vegetation growth. The planting of vegetation allows the roots to penetrate deep into the soil, forming a stable root network, preventing soil loss. This not only beautifies the slope landscape but also enhances the slope's soil retention capacity, further consolidating the slope's stability.
[0028] Concrete is poured into the anchor hole 3 to form a concrete anchor 5, which is fixedly connected to the foundation rock layer 1. The concrete anchor 5 is then connected to the foundation rock layer 1 by pouring concrete into the anchor hole 3, and then the anchor structure is connected to the slope reinforcement structure set outside the embankment slope 2. The concrete anchor 5, with its strong bonding force and tensile strength, firmly locks the slope reinforcement structure set outside the embankment slope 2 onto the embankment slope 2, making the entire slope fixing system more stable and durable.
[0029] A drainage ditch 14 is provided at the bottom of the embankment slope 2, and the inner wall surface of the drainage ditch 14 is provided with a concrete slope 15. The drainage ditch 14 can effectively guide rainwater or accumulated water to flow smoothly out, avoiding erosion and damage to the embankment slope 2. The concrete slope 15 not only enhances the structural strength of the drainage ditch 14, but also improves its weather resistance and durability, ensuring that the drainage ditch 14 maintains good drainage function during long-term use.
[0030] The reinforcing channels 6 are arranged in a crisscross pattern, with their intersection points located at the concrete anchorages 5. The reinforcing steel bars 8 are tightly connected to one end of the anchor cables 4 via steel reinforcement. This crisscrossing layout of the reinforcing channels 6 forms a robust grid system. The intersection points at the concrete anchorages 5 facilitate the tight connection between the reinforcing steel bars 8 and the anchor cables 4, creating a strong grid system. This arrangement makes the entire structure more tightly connected and less susceptible to external impacts. The tight connection between the reinforcing steel bars 8 and the anchor cables 4 not only enhances the connection strength between the steel bars and the anchor cables but also further improves the shear and tensile strength of the slope reinforcement structure.
[0031] The anchor cables 4, reinforcing bars 8, and protective wire mesh 13 have all undergone special anti-corrosion treatment. This ensures that these components maintain good performance even in harsh environments, effectively resisting corrosion and rust, and extending their service life. This anti-corrosion treatment not only improves the durability of individual components but also ensures the long-term stability and reliability of the entire slope reinforcement system.
[0032] Working principle: Anchor holes 3 are rationally constructed according to the area of the embankment slope 2. Anchor cables 4 are inserted into the foundation rock layer 1 through the anchor holes 3. Concrete is poured into the anchor holes 3 to form concrete anchors 5, which are then fixedly connected to the foundation rock layer 1. The anchor cables 4 are then connected to the slope reinforcement structure set on the outside of the embankment slope 2, ensuring a tight bond between the slope reinforcement structure and the embankment slope 2, forming a stable whole. Reinforcement channels 6 are opened on the surface of the embankment slope 2 to provide reliable placement space for the reinforcing steel bars 8. After the reinforcing steel bars 8 are placed, one end of the reinforcing steel bars 8 is tightly connected to one end of the anchor cables 4 with steel bars, forming a strong grid system. Then, concrete is poured into the reinforcement channels 6 to form a concrete reinforcement strip 9. The concrete reinforcement strip 9 not only fills the reinforcement channels 6 but also tightly wraps the connection between the reinforcing steel bars 8 and the anchor cables 4, greatly enhancing the structural integrity. The overall stability and durability of the structure are enhanced by the toothed protrusions 11 on the reinforcing steel bar 8, which effectively increases the interlocking force between the reinforcing steel bar 8 and the concrete, preventing the reinforcing steel bar 8 from slipping in the concrete and further improving the reinforcement effect of the slope. The conical grooves 7 set on the reinforcing channel 6 increase the friction between the concrete and the reinforcing channel 6, making the connection between the concrete reinforcing strip 9 and the reinforcing channel 6 more secure. This makes the concrete reinforcing strip 9 more firmly attached to the slope, less prone to loosening or falling off, and prevents slope instability caused by soil loosening or water erosion. Multiple reinforcing structures are firmly fixed together to form a sturdy and durable slope protection structure. This structure not only improves the stability of the slope, but also extends the service life of the road, enhances the structural stability of the embankment slope, and greatly improves its resistance to sliding and shear.
