Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of anchor rod protection equipment, and specifically relates to a high and steep slope facade greening solidified fiber soil reinforced anchor rod protection structure. BACKGROUND

[0002] In the construction of infrastructures such as mountainous highways, railways and water conservancy projects and engineering activities such as mining, high and steep slopes are often encountered. Due to the large slope and high height of the high and steep slope, under the influence of natural factors (such as rainwater erosion, weathering, earthquakes, etc.) and human factors (such as engineering excavation, blasting, etc.), geological disasters such as landslides and collapses are prone to occur, which seriously threatens the safe operation of engineering facilities and the surrounding environment and the lives and property of personnel.

[0003] Referring to CN215053124U, an anchor rod protection structure for preventing high slope mountain landslide, comprising a fixing mechanism, a dismounting mechanism and an adjusting mechanism, the right side of the fixing mechanism is provided with the dismounting mechanism, and the left side of the fixing mechanism is provided with the adjusting mechanism; the adjusting mechanism comprises a slot arranged in the middle part of the surface of the fixing mechanism. The anchor rod protection structure for preventing high slope mountain landslide, when the anchor rod is fixed, the user twists the connecting plate and the connecting frame to dismount the fixing cylinder and the threaded rod, which facilitates the maintenance and replacement of the connecting plate, the connecting frame and the parts on the surface thereof. The user slides the lower hook along the sliding groove, which facilitates the adjustment of the metal net to the appropriate position. Then, the rotating rod is rotated to move upward. Since the rotating rod constitutes a rotating structure through the fixing disc and the rotating groove, the rotation of the rotating rod does not affect the upward movement of the movable plate. When the limiting block at the end of the movable plate passes through the limiting hole, the lower hook is fixed.

[0004] When the limiting block at the end of the movable plate passes through the limiting hole, the lower hook is fixed.

[0005] There are various traditional slope protection methods, such as soil retaining wall protection, which mainly relies on the weight and structural strength of the wall body to resist the lateral pressure of the slope soil body. However, for high and steep slopes, the height and foundation of the soil retaining wall require higher cost and have great construction difficulty in some complex geological conditions. There is also vegetation protection, which can reduce soil and water loss on the slope to some extent, but for high and steep slopes with poor stability, the reinforcement effect is limited and cannot effectively prevent deep sliding of the soil body. As a relatively effective slope reinforcement means, anchor rod protection technology has been widely applied in engineering practice.

[0006] However, some existing anchor rod protection structures still have some deficiencies. Some anchor rods have insufficient anchoring force under complex geological conditions and are prone to loosening and pulling out. Some anchor rod protection structures have low protection effect when subjected to long-term rainwater erosion and weathering. CONTENT OF THE UTILITY MODEL

[0007] The purpose of this application is to address the problems mentioned above, such as insufficient anchoring force of some anchors under complex geological conditions, which makes them prone to loosening and pull-out, and the low protective effect of some anchor protection structures when subjected to long-term rainwater erosion and weathering. This application provides a high-steep slope facade greening and solidification fiber soil reinforced anchor protection structure.

[0008] The technical solution adopted in this application is as follows: a high and steep slope facade greening and solidification fiber soil reinforcement anchor protection structure, including a grouting anchor, one end of which is fixedly connected to a first cone head, the surface of which is fixedly connected to a first barb, the side of which is threadedly connected to a threaded cylinder, the side of which is away from the grouting anchor is fixedly connected to a knob plate, the surface of which is fixedly fitted with a pressure plate, the surface of which is fixedly connected to a connecting plate, the side of which is away from the pressure plate is fixedly connected to a protective frame plate, and the inner ring surface of which is fixedly connected to a protective net.

[0009] By adopting the above technical solution, firstly, external drilling equipment is used to drill holes in the slope. Then, grouting anchors are placed into the drill holes, and the first cone is inserted deep into the slope. Next, cement grout is poured into the grouting anchors. The cement grout flows out from the grout outlet on the surface of the grouting anchors to seal the drill holes. Then, the knob plate is rotated, which drives the threaded cylinder to rotate. The threaded cylinder rotates and is fixed to the grouting anchors. At this time, the plug blocks the grouting anchors, and the edge of the threaded cylinder seals the gap between the grouting anchors and the inner wall of the drill holes. Then, the pressure plate is passed through the screw and the nut is rotated to fix the pressure plate to the threaded cylinder. Finally, the second cone is passed through the round hole and chiseled into the slope, so that the equipment can effectively strengthen the protection of the slope.

[0013] By adopting the above technical solution and setting grout flow holes, cement can flow out from the grouting anchor to seal the gap between the grouting anchor and the drill hole. At the same time, the anti-corrosion coating protects the grouting anchor and reduces its corrosion.

[0014] In a preferred embodiment, a plug is fixedly connected to the inner wall of the threaded cylinder, and the surface of the plug is adapted to the inner wall of the grouting anchor rod.

[0015] By adopting the above technical solution, the plugging block can enter the grouting anchor rod to seal the grout when the threaded cylinder is fixed on the surface of the grouting anchor rod, thereby reducing the occurrence of grout leakage.

[0016] In a preferred embodiment, a screw is fixedly connected to the side of the knob plate away from the grouting anchor rod, and a nut is threaded onto the surface of the screw rod.

[0017] By adopting the above technical solution and by setting a nut, the pressure plate can be fixed to the knob plate by a screw after rotation.

[0018] In a preferred embodiment, a gasket is fitted onto the surface of the screw.

[0019] By adopting the above technical solution and setting a shim, the fixing between the pressure plate and the knob plate can be strengthened in conjunction with the nut.

[0020] In a preferred embodiment, the pressure plate has a through hole on its side, and the inner wall of the through hole is adapted to the surface of the screw.

[0021] By adopting the above technical solution and setting through holes, the screw can pass through the pressure plate, which makes it easier for the pressure plate to be fixed after the nut rotates.

[0022] In a preferred embodiment, the grouting anchor has a circular hole on its side, and a second cone is provided on the inner wall of the circular hole. A hammer plate is fixedly connected to one end of the second cone, and a second barb is fixedly connected to the surface of the second cone.

[0023] By adopting the above technical solution and setting a hammer plate, it is possible to facilitate the use of external tools to drive the second cone head into the slope.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0025] 1. In this application, firstly, external drilling equipment is used to drill holes in the slope. Then, grouting anchors are placed into the drill holes, and the first cone is inserted deep into the slope. Cement grout is then injected into the grouting anchors, and the cement grout flows out from the grout outlet on the surface of the grouting anchors to seal the drill holes. Next, the knob plate is rotated, which drives the threaded cylinder to rotate. The threaded cylinder rotates and is fixed to the grouting anchors. At this time, the plug blocks the grouting anchors, and the edge of the threaded cylinder seals the gap between the grouting anchors and the inner wall of the drill holes. Then, the pressure plate is passed through the screw and the nut is rotated to fix the pressure plate to the threaded cylinder. Finally, the second cone is passed through the round hole and chiseled into the slope, so that the device can effectively strengthen the protection of the slope. Attached Figure Description

A threaded cylinder 12 is threadedly connected to the side of the grouting anchor 1. A knob plate 11 is fixedly connected to the side of the threaded cylinder 12 away from the grouting anchor 1. A pressure plate 5 is fixedly fitted onto the surface of the knob plate 11. A connecting plate 9 is fixedly connected to the surface of the pressure plate 5. First, a hole is drilled in the slope using external drilling equipment. Then, the grouting anchor 1 is inserted into the drilled hole, and the first cone head 13 is inserted deep into the slope. Cement grout is injected into the grouting anchor rod 1. The cement grout flows out from the grout flow hole 2 on the surface of the grouting anchor rod 1 to seal the borehole. Then, the knob plate 11 is rotated, which drives the threaded cylinder 12 to rotate. The threaded cylinder 12 rotates and is fixed on the grouting anchor rod 1. At this time, the plug block 15 seals the grouting anchor rod 1. The edge of the threaded cylinder 12 seals the gap between the grouting anchor rod 1 and the inner wall of the borehole. Then, the pressure plate 5 is passed through the screw rod 4 and the nut 3 is rotated to fix the pressure plate 5 on the threaded cylinder 12. Then, the second cone 7 is passed through the round hole 19 and chiseled into the slope. The protective frame plate 10 is fixedly connected to the side of the connecting plate 9 away from the pressure plate 5.

[0034] Reference Figures 2-4The inner ring surface of the protective frame plate 10 is fixedly connected with a protective net 18. By setting the protective frame plate 10, the protective net 18 can be attached to the slope, reducing the collapse of large soil blocks on the slope and strengthening the protection of the slope.

[0035] Reference Figures 2-3 The grouting anchor 1 has a grout flow hole 2 on its surface, and the surface of the grouting anchor 1 is coated with an anti-corrosion coating. By setting the grout flow hole 2, cement can flow out from the grouting anchor 1 to seal the gap between the grouting anchor 1 and the drill hole. At the same time, the anti-corrosion coating protects the grouting anchor 1 and reduces the corrosion of the grouting anchor 1.

[0036] Reference Figures 1-2 A plug 15 is fixedly connected to the inner wall of the threaded cylinder 12. The surface of the plug 15 is adapted to the inner wall of the grouting anchor rod 1. Through the plug 15, when the threaded cylinder 12 is fixed to the surface of the grouting anchor rod 1, the plug 15 enters the grouting anchor rod 1 to seal the mud and reduce the occurrence of mud outflow.

[0038] Reference Figures 1-3 The screw 4 is fitted with a washer 16. By setting the washer 16, it can be used to reinforce the fixation between the pressure plate 5 and the knob plate 11 in conjunction with the nut 3.

[0039] Reference Figures 1-3 The pressure plate 5 has a through hole 17 on its side. The inner wall of the through hole 17 is adapted to the surface of the screw 4. By setting the through hole 17, the screw 4 can pass through the pressure plate 5, which makes it easy for the nut 3 to rotate and fix the pressure plate 5.

[0040] Reference Figures 1-2 The side of the grouting anchor 1 has a round hole 19, and the inner wall of the round hole 19 is provided with a second cone 7. One end of the second cone 7 is fixedly connected to a hammer plate 6, and the surface of the second cone 7 is fixedly connected to a second barb 8.

[0041] The implementation principle of this application for a high and steep slope facade greening and solidification fiber soil reinforcement anchor protection structure is as follows: First, the slope is drilled using external drilling equipment. Then, the grouting anchor 1 is placed into the drill hole, and the first cone 13 is inserted deep into the slope. Then, cement grout is injected into the grouting anchor 1. The cement grout flows out from the grout outlet 2 on the surface of the grouting anchor 1 to seal the drill hole. Next, the knob plate 11 is rotated, which drives the threaded cylinder 12 to rotate. The threaded cylinder 12 rotates and is fixed on the grouting anchor 1. At this time, the plug 15 seals the grouting anchor 1. The edge of the threaded cylinder 12 seals the gap between the grouting anchor 1 and the inner wall of the drill hole. Then, the pressure plate 5 is passed through the screw 4 and the nut 3 is rotated to fix the pressure plate 5 on the threaded cylinder 12. Then, the second cone 7 is passed through the round hole 19 and chiseled into the slope, so that the device can easily strengthen the slope protection effect.
