Description

Technical Field

[0001] This invention belongs to the field of slope reinforcement technology, and in particular to a reinforcement structure and method for use on rock and soil slopes. Background Technology

[0002] Slope reinforcement aims to enhance slope stability and prevent geological disasters such as soil erosion, landslides, and slope collapses. Common methods of slope protection include: for rock faces, anchoring the slope protection netting by driving anchors into the rock strata; the netting's support prevents rocks from rolling down and protects the slope from weathering and erosion; for slopes with soil layers, vegetation protection is often used as an auxiliary reinforcement method, using plant roots to stabilize the topsoil, reduce erosion, and prevent soil loss. However, existing reinforcement structures have limited adjustment capabilities, which restricts their applicability.

[0003] A search revealed a Chinese patent document (authorization announcement number CN118481160B) for a slope reinforcement device in geotechnical engineering. This device includes positioning components and geogrid modules. Several geogrid modules are spliced ​​and fixed to several positioning components. Each positioning component includes an anchor rod with external threads, a positioning seat rotatably sleeved on the anchor rod, a knob threadedly connected to the anchor rod, and a clamping seat rotatably sleeved on the knob. The positioning seat and clamping seat clamp the corners of the geogrid modules. The clamping seat has several positioning sleeves and a channel connecting the positioning sleeves. A sleeve is detachably inserted between the positioning sleeves of adjacent clamping seats. Several discharge holes are provided on the side wall of the sleeve. A cylindrical positioning element is provided on the side of the geogrid module. The sleeve passes through the cylindrical positioning element, and a baffle extends axially from the cylindrical positioning element. The positioning angle of the sleeve on the positioning sleeve can be adjusted to adjust the angle and flow rate of the discharge holes, or to adjust the discharge holes until they are blocked by the baffle. The reinforcement structure of the above patent has weak adjustment capabilities, which may affect its applicability. Summary of the Invention

[0004] The purpose of this invention is to provide a reinforcement structure and method for use on rock and soil slopes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reinforcement structure for rock and soil slopes, comprising: a protective net for protecting the rock and soil slopes, wherein four reinforcement components are provided on the outer periphery of the protective net for reinforcing both the protective net and the rock and soil slopes, and the protective net is also connected to multiple adjustment and fixing components for improving the stability between the protective net and the rock and soil slopes;

[0006] Each of the four reinforcement components includes multiple fixing plates, which are staggered. Insert blocks are fixedly connected to the sides of the fixing plates. Multiple rectangular channels for the insert blocks to pass through are opened on the outer periphery of the fixing plates. Multiple threaded channels communicating with the rectangular channels are opened at the top of the fixing plates. T-shaped fixing anchor rods are threadedly connected to the threaded channels. The top of each insert block also has a round hole for the fixing anchor rod to pass through.

[0007] As a preferred embodiment, the bottom end of the fixing plate is also provided with a plurality of auxiliary holes corresponding to the positions of the threaded channels for the fixing anchor rods to pass through.

[0008] As a preferred embodiment, the top of the reinforcement component is provided with an inclined connecting plate to enhance stability, and the top of the inclined connecting plate has two round holes for the fixed anchor rods to pass through.

[0009] As a preferred embodiment, the adjustment and reinforcement assembly includes a pressure plate for pressing and fixing the protective net and a T-shaped adjustment anchor rod. The top of the pressure plate has a plurality of threaded holes arranged at equal intervals to fit the adjustment anchor rod.

[0010] In a preferred embodiment, the adjusting anchor is threadedly connected to the threaded hole and penetrates into the interior of the rock and soil slope.

[0011] As a preferred embodiment, the pressure plate has a combination channel on its outer periphery, and an L-shaped insert plate for matching the combination channel is fixedly connected to the outer periphery of the pressure plate. After the insert plate is inserted into the combination channel, it is used for combination assembly.

[0012] In a preferred embodiment, the side of the insert plate is rotatably connected to an anti-detachment block via a damping shaft, and the cross-section of the insert plate is the same as that of the anti-detachment block.

[0013] A method for using a reinforcement structure for rock and soil slopes includes the following steps:

[0014] Step 1: Material preparation: Select appropriate size protective netting for laying according to the required dimensions of the soil and rock slope to be reinforced;

[0015] Step 2, Soil and Rock Slope Reinforcement: Select an appropriate number of fixing plates, then arrange them in a staggered manner. Next, prepare inclined connecting plates and use several fixed anchor rods to fix the fixing plates and inclined connecting plates to achieve reinforcement and stability of the protective net and soil and rock slope.

[0016] Step 3: Adjustment and reinforcement: Adjust and reinforce specific locations in the soil and rock slope area. If the reinforcement area is large, multiple adjustment and fixing components can be fixed. Insert the insert plate of the pressure plate into the combination channel of another pressure plate, then rotate the anti-detachment block to hold the pressure plate, and use the adjusting anchor rod to connect with the threaded hole and insert it into the interior of the soil and rock slope for fixation.

[0017] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0018] The reinforcement structure and application method for this soil and rock slope benefit from the design of the reinforcement components. The staggered combination of multiple fixing plates can adapt to the reinforcement needs of different lengths. When using inserts for combination, fixed anchor rods can also be used for fixation, ensuring the stability of the combination and the stability of the soil and rock slope reinforcement.

[0019] The reinforcement structure and application method for this soil and rock slope benefit from the combination of reinforcement components and inclined connecting plates. The arrangement of multiple reinforcement components in different forms and orientations can adapt to the reinforcement of soil and rock slopes with different needs. The design of the inclined connecting plates can improve the stability and adaptability of the connection.

[0020] The reinforcement structure and application method for this soil and rock slope benefit from the design of the adjustable fixing components. For specific unstable locations on the soil and rock slope, the protective net can be pressed with pressure plates and then fixed with adjusting anchor rods. If the area of ​​the location is large, insert plates can be used for combination, and anti-detachment blocks can be rotated to limit the position and ensure the stability of the combination.

[0021] The reinforcement structure and application method for this rock and soil slope can be adjusted and reinforced to meet various application needs. Attached Figure Description

[0033] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0034] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0035] This application is suitable for relatively uniform soil and rock slopes, and the soil and rock slopes are convenient for anchor bolts to be drilled and fixed. It is not suitable for harder or softer soil and rock types.

[0036] The differences between soil slopes and rock slopes lie in three aspects: material composition, failure mechanism, and stability calculation methods. The material composition of a slope is the difference between soil and rock. Soil and rock are similar in material composition (soil is a weathering product of rock), but their structures differ greatly. Soil is a loose accumulation of particles, while rock mass is a blocky mass with various irregular joints and faults. The failure mechanisms of the two differ. Failure of soil slopes is mainly a problem of soil stability, generally resulting from sliding failure, caused by shear stress on the sliding surface exceeding its shear strength. Instability failure of rock slopes is often closely related to the development of joints in the sliding surface and rock mass. Besides sliding failure, rock slope failure can also be classified as collapse failure, which lacks a clear failure surface and is caused by stress exceeding the strength of the rock mass. In analysis and calculation, both are based on sliding failure, but the methods used differ. Soil slopes are generally calculated using the Swedish circular arc slice method, while soil and rock slopes, due to the existence of multiple structural surfaces, generally use the transfer coefficient method.

[0037] Please see Figures 1 to 6 A reinforcement structure for rock and soil slopes, in this embodiment, includes: a protective net 1 for protecting the rock and soil slope; a protective net 1 of appropriate size is selected and laid according to the size of the rock and soil slope to be reinforced; four reinforcement components 2 are provided on the outer periphery of the protective net 1 for reinforcing both the protective net 1 and the rock and soil slope; the protective net 1 is also connected to multiple adjustment and fixing components 3 to improve the stability between the protective net 1 and the rock and soil slope.

[0038] Each of the four reinforcement components 2 includes multiple fixing plates 21, which are staggered. Insert blocks 22 are fixedly connected to the sides of each fixing plate 21. Multiple rectangular channels for the insert blocks 22 to pass through are opened on the outer periphery of each fixing plate 21. Multiple threaded channels communicating with the rectangular channels are opened at the top of each fixing plate 21. T-shaped anchor rods 23 are threadedly connected to the threaded channels. Circular holes for the anchor rods 23 to pass through are also opened at the top of each insert block 22. Multiple auxiliary holes corresponding to the positions of the threaded channels are also opened at the bottom of each fixing plate 21 for the anchor rods 23 to pass through. A suitable number of fixing plates 21 are selected and then staggeredly combined. An inclined connecting plate 4 is then prepared, and several anchor rods 23 are used to fix the fixing plates 21 and the inclined connecting plate 4, thereby achieving reinforcement and stability of the protective netting 1 and the soil slope.

[0039] The top of the reinforcement component 2 is provided with an inclined connecting plate 4 to improve stability, and the top of the inclined connecting plate 4 has two round holes for the fixed anchor rod 23 to pass through.

[0040] The adjusting and reinforcing component 2 includes a pressure plate 31 for pressing and fixing the protective netting 1 and a T-shaped adjusting anchor rod 32. The top of the pressure plate 31 has multiple equally spaced threaded holes adapted to the adjusting anchor rods 32. The adjusting anchor rods 32 are threadedly connected to the threaded holes and penetrate into the interior of the soil slope. A combination channel is formed on the outer periphery of the pressure plate 31. An L-shaped insert plate 33 adapted to the combination channel is fixedly connected to the outer periphery of the pressure plate 31. After the insert plate 33 is inserted into the combination channel, it is used for assembly. The side of the insert plate 33 is rotatably connected to the anti-detachment block 34 via a damping shaft. The cross-section of the insert plate 33 is the same as that of the anti-detachment block 34. It is used to adjust and reinforce specific locations in the soil and rock slope area. If the reinforcement area is large, multiple adjustment and fixing components 3 can be fixed. The insert plate 33 of the pressure plate 31 is inserted into the combined channel of another pressure plate 31. Then, the anti-detachment block 34 is rotated to abut against the pressure plate 31. The adjusting anchor rod 32 is threadedly connected to the threaded hole and inserted into the interior of the soil and rock slope for fixation.

[0041] If the time is long, the limiting effect of the anti-detachment plate 34 will weaken, and after the pressure plate 31 is fixed, the insertion plate 33 will not easily come out of the pressure plate 31, thus ensuring the stability of the assembly.

[0042] Since this application is exposed to the elements for extended periods, all structures and instruments have been treated with waterproofing and corrosion protection to ensure safe use.

[0043] A method for using a reinforcement structure for rock and soil slopes includes the following steps:

[0044] Step 1: Material preparation: Select a suitable size of protective netting 1 for laying according to the size of the rock and soil slope to be reinforced;

[0045] Step 2, Soil and Rock Slope Reinforcement: Select an appropriate number of fixing plates 21, then combine them in a staggered manner, and then prepare the inclined connecting plate 4. Use several fixing anchors 23 to fix the fixing plates 21 and the inclined connecting plate 4 to achieve reinforcement and stability of the protective net 1 and the soil and rock slope.

[0046] Step 3: Adjustment and reinforcement: Adjustment and reinforcement are carried out at specific locations in the soil and rock slope area. If the reinforcement area is large, multiple adjustment and fixing components 3 can be fixed. Insert the insert plate 33 of the pressure plate 31 into the combination channel of another pressure plate 31, then rotate the anti-detachment block 34 to abut the pressure plate 31, and use the adjustment anchor rod 32 to connect with the threaded hole and insert it into the interior of the soil and rock slope for fixation.
