Description

Technical Field

[0001] This invention relates to the field of building slope protection technology, specifically to a slope reinforcement method for municipal engineering. Background Technology

[0002] Slope protection is an active protection system in municipal engineering. It consists of various flexible nets, primarily steel wire rope netting, covering and wrapping the slope or rock face requiring protection. This restricts weathering and erosion of the slope's rock and soil, preventing rockfalls and providing reinforcement. It also controls the movement of falling rocks within a certain range, acting as a retaining structure. In municipal engineering, the lower part of the slope is usually located near urban roads or areas with high population density and vehicle traffic, making slope stability crucial. Currently, slope protection involves fixing the netting to the slope with long spikes, followed by pouring a buffer platform on the upper part of the slope's base, with drainage ditches installed on the platform. This structure has the following problems: First, the overall pressure from the slope's gradient presses down on the buffer platform at the bottom, and without anchoring components, landslides are likely to occur. Second, the netting is directly fixed with long spikes, making it susceptible to loosening due to falling rocks, wind, or vegetation growth. Third, the netting is a single unit; damage in one area requires replacement of the entire unit, resulting in high maintenance costs and time-consuming and labor-intensive disassembly and reassembly. Therefore, it is necessary to design a slope reinforcement method for municipal engineering to solve the problems of existing slopes being prone to landslides due to lack of anchorage and the insecure fixation of long nails. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of this invention is to provide a slope reinforcement method for municipal engineering.

[0004] The technical solution adopted by this invention to solve its technical problem is: a slope reinforcement method for municipal engineering, comprising the following steps:

[0005] S1: Repair the slope, creating at least one buffer platform.

[0006] S2: Slope fixed-point reinforcement, pour concrete blocks on the buffer platform, and install anchoring mechanisms at the concrete blocks;

[0007] S3: The anchoring mechanism is inserted at an angle into the slope to form a rivet structure for the slope;

[0008] S4: Overall slope reinforcement. Protective netting mechanisms are installed on the slope's sloping sides and buffer platforms. The protective netting mechanisms are fixed to the slope using a nailing structure.

[0009] Specifically, in step S1), the lower part of the slope is trimmed to form a flat surface, and a buffer platform is set at the connection between the flat surface and the slope. A concrete block and a drainage ditch are set on the lowest buffer platform of the slope.

[0010] Specifically, the concrete block adopts a square structure and has a 45° inclined surface near the downward direction of the slope, and an anchoring mechanism is installed on the inclined surface.

[0011] Specifically, the anchoring mechanism in step S2) includes an anchoring hole, an anchoring end sleeve, and an anchor rod. The anchoring hole is drilled into the inclined surface of the concrete block. The horizontal inclination angle of the anchoring hole is 30°-50°. The anchoring end sleeve is provided with a first stop block, and the lower part of the anchor rod is provided with a second stop block. The anchor rod extends into the anchoring end sleeve, and the first and second stops block are staggered. The end of the anchor rod presses against the anchoring end sleeve and enters the anchoring hole. The outer end of the anchor rod is pushed in by a hydraulic jack. Then, the anchor rod is clamped and rotated by a wrench so that the second stop block is blocked inside the first stop block.

[0012] Specifically, the outer periphery of the anchoring end sleeve is provided with several protruding barbs, and the tips of the protruding barbs press against the inner wall of the anchoring hole.

[0013] Specifically, the anchor rod is provided with multiple fastening structures on its outer periphery. Each fastening structure includes three sets of support rods.

One end of the support rod is rotatably connected to the anchor rod through a second pivot, and the other end of the support rod is rotatably connected to the top plate through a first pivot. The outside of the top plate contacts the inner wall of the anchor hole. The support rods are inclined from bottom to top from the anchor rod side to the top plate side.

[0014] Specifically, the anchor rod has threads on its outer side, a nut is threaded onto the anchor rod, and a sealing cover plate is also fitted onto the anchor rod. The sealing cover plate is located between the nut and the concrete block. Tightening the nut fixes the anchor rod and presses the sealing cover plate.

[0015] Specifically, the protective netting mechanism in step S4) includes a net frame, long nails, a pressure nail structure, and a protective net. The protective net is fixed on the net frame, and the net frames are spliced ​​together to form an overall reinforcement structure on the slope. The net frame is provided with at least four mounting holes, and long nails are inserted into the mounting holes. The long nails pass through the net frame and are inserted into the slope, and the long nails fix the net frame on the slope.

[0016] Specifically, the pressure nail structure includes a pressure nail wheel, a pressure nail block, a pressure arm, a support seat, and a spring seat.

A handle is connected to the outer side of the pressure nail block for controlling the lifting or pressing of the pressure nail block by operating the handle. The pressure nail wheel rolls on the upper surface of the long nail. When the handle is below the horizontal plane, the pressure nail wheel presses the long nail.

[0017] Specifically, a compression spring is installed between the elastic seat and the support seat, and a bolt passes through the inside of the compression spring. The bolt passes through the elastic seat and is threaded to the bottom of the support seat.

[0018] The present invention has the following beneficial effects:

[0030] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. 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.

[0031] Example 1: As Figure 1-7 As shown, a slope reinforcement method for municipal engineering includes the following steps:

[0032] 1. Repair slope 3, and repair slope 3 to create four buffer platforms 4 to release the pressure of slope 3 in sections; repair the lower part of slope 3 to create a flat surface, and the connection between the flat surface and slope 3 is the lowest buffer platform 4. The lowest buffer platform 4 of slope 3 is equipped with concrete pouring blocks 5 and drainage ditches 6, while the other buffer platforms 4 in the middle are only equipped with concrete pouring blocks 5.

[0033] The concrete block 5 adopts a square structure and has a 45° inclined surface near the slope 3 in the downward direction. An anchoring mechanism 1 is installed on the inclined surface.

[0034] 2. Slope 3 is reinforced at fixed points. Concrete blocks 5 are poured on buffer platform 4, and anchoring mechanisms 1 are installed at the concrete blocks 5. The anchoring mechanisms 1 are inserted into the slope 3 at an angle to form a rivet structure for the slope. The inclined anchoring mechanisms 1 installed on buffer platform 4 increase the stability of slope 3 and greatly reduce the risk of landslides.

[0035] The anchoring mechanism 1 includes an anchoring hole 1.1, an anchoring end sleeve 1.2, a fastening structure, and an anchor rod 1.5. The anchoring hole 1.1 is drilled into the inclined surface of the concrete block 5. The horizontal inclination angle of the anchoring hole 1.1 is 45°. The anchoring end sleeve 1.2 has two opposing stops 1.3 inside. The lower part of the anchor rod 1.5 has two opposing stops 1.6. The anchor rod 1.5 extends into the anchoring end sleeve 1.2, and the stops 1.3 and 1.6 are staggered. The end of the anchor rod 1.5 presses against the anchoring end sleeve 1.2 and enters the anchoring hole 1.1. The outer end of the anchor rod 1.5 is pushed in by a hydraulic jack. Then, the anchor rod 1.5 is clamped and rotated by a wrench so that the stops 1.6 are blocked inside the stops 1.3. The stops 1.3 and 1.6 prevent the anchor rod from being pulled out.

[0036] The outer periphery of the anchor end sleeve 1.2 is provided with several protruding barbs 1.4. The tips of the protruding barbs 1.4 press against the inner wall of the anchor hole 1.1. The protruding barbs 1.4 prevent the anchor end sleeve 1.2 from being pulled away from the anchor hole 1.1 by the anchor rod 1.5.

[0037] The outer periphery of the anchor bolt 1.5 is provided with multiple sets of fastening structures. Each set of fastening structures includes three sets of support rods 1.7. The included angle between the three sets of support rods 1.7 on the cross-section of the anchor bolt 1.5 is 120°. Each set of support rods 1.7 has four rods.

The outer surface of the top plate 1.8 contacts the inner wall of the anchor hole 1.1, and the support rods 1.7 are self-anchored. The rod 1.5 is inclined from bottom to top towards the top plate 1.8. The fastening assembly is supported between the anchor rod 1.5 and the anchor hole 1.1 in a tripod structure. When the anchor rod 1.5 moves into the anchor hole 1.1, the support rod 1.7 and the top plate 1.8 are aligned. When the anchor rod 1.5 moves outward from the anchor hole 1.1, friction is generated between the top plate 1.8 and the inner wall of the anchor hole 1.1. The support rod 1.7 provides limiting support to prevent the anchor rod 1.5 from coming out of the anchor hole 1.1.

[0038] The anchor rod 1.5 has threads on its outer side and a threaded nut 1.12 on it. A sealing cover plate 1.11 is also fitted on the anchor rod 1.5. The sealing cover plate 1.11 is located between the nut 1.12 and the concrete block 5. Tightening the nut 1.12 fixes the anchor rod 1.5 and presses the sealing cover plate 1.11. At the same time, the support rod 1.7 and the protruding barb 1.4 both serve a supporting function.

[0039] 3. The slope 3 is reinforced as a whole. Protective netting mechanisms 2 are installed on both the sloping side of slope 3 and the buffer platform 4. The protective netting mechanisms 2 fix the mesh frame 2.1 to the slope 3 using a nailing structure. The protective netting structure is spliced ​​from the mesh frame 2.1, facilitating maintenance and replacement, reducing maintenance costs. Furthermore, quick-release nailing structures are installed on the long nails 2.2 to ensure their reliability, prevent loosening, and improve the stability of the slope 3 protection.

[0040] The protective netting mechanism 2 includes a net frame 2.1, long nails 2.2, a pressure nail structure, and a protective net. The protective net is fixed on the net frame 2.1. The net frames 2.1 are spliced ​​together to form an integral reinforcement structure on the slope 3. The net frame 2.1 is provided with four mounting holes. Long nails 2.2 are inserted into the mounting holes. The pressure nail structure is installed at the mounting holes. The long nails 2.2 pass through the net frame 2.1 and are inserted into the slope 3. The long nails 2.2 fix the net frame 2.1 to the slope 3.

[0041] The pressure rivet structure includes a pressure rivet wheel 2.3, a pressure rivet block 2.4, a pressure arm 2.5, a support seat 2.6, a spring seat 2.7, and a compression spring 2.8. The bottom of the support seat 2.6 is fixed to the space frame 2.1. The upper part of the support seat 2.6 has a U-shaped groove 1, and two pin holes for pins are provided on both sides of the U-shaped groove 1. The upper part of the spring seat 2.7 has a U-shaped groove 2, and two pin holes for pins are provided on both sides of the U-shaped groove 2. The pressure arm 2.5 has a strip-shaped pin hole on one side, and the strip-shaped pin hole of the pressure arm 2.5 is rotatably installed in the U-shaped groove 2 via a pin. The middle part of the pressure arm 2.5 is rotatably mounted in the U-shaped groove through a pin. The other side of the pressure arm 2.5 is rotatably connected to the nail pressing block 2.4 through a pin. Both sides of the lower part of the nail pressing block 2.4 are equipped with nail pressing wheels 2.3. The outer side of the nail pressing block 2.4 is connected to a handle 2.9, which is used to control the lifting or pressing of the nail pressing block 2.4 by operating the handle 2.9. The nail pressing wheel 2.3 rolls on the upper surface of the long nail 2.2. When the handle 2.9 is lower than the horizontal plane, the nail pressing wheel 2.3 presses the long nail 2.2, and the lever principle is used to achieve rapid pressing of the long nail 2.2.

[0042] A compression spring 2.8 is installed between the spring seat 2.7 and the support seat 2.6. A bolt passes through the inside of the compression spring 2.8. The bolt passes through the spring seat 2.7 and is threaded to the bottom of the support seat 2.6. The height of the spring seat 2.7 is adjusted by rotating the bolt, thereby adjusting the pressing tightness of the handle 2.9, and further adjusting the force of the nail pressing wheel 2.3 pressing the long nail 2.2.
