Description

Technical Field

[0001] This utility model relates to the field of embankment slope construction, specifically a reinforcing anchor rod for embankment slope construction. Background Technology

[0002] Slope reinforcement refers to measures to improve the stability of open-pit mine slopes. It involves installing retaining walls at the slope angle of the fractured zone, inserting reinforcing anchors, installing anti-slide piles in local fractured zones or on the slope, and grouting rock strata with open joints and fissures. Do anchors need to be removed? Anchors are the most basic component of roadway support in modern coal mines. They reinforce the surrounding rock of the roadway, allowing the surrounding rock to support itself. Anchors are not only used in mines but also in engineering technology for the main reinforcement of slopes, tunnels, and dams.

[0003] Currently, anchor bolts are usually rod-shaped anchor bolts with tapered ends. The small contact area when the anchor bolt is directly inserted into the slope soil reduces the reinforcement effect and causes loosening. Some anchor bolts also have an extension structure at the end to increase the anchor bolt's grip, but the installation of anchor bolts is relatively laborious and the subsequent disassembly and removal of the anchor bolts is inconvenient. Therefore, it is necessary to design a reinforcement anchor bolt for embankment slope construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcing anchor for embankment slope construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforcing anchor rod for embankment slope construction, comprising an anchor rod body, a fixing block screwed to the outside of the anchor rod body, a fixing component for reinforcing the slope installed on the outside of the fixing block, an anti-detachment component for preventing the anchor rod body from detaching installed on the outside of the anchor rod body near the end, and a drive component for opening and closing the anti-detachment component installed on the inside of the anchor rod body.

[0006] Preferably, the anti-detachment component includes a pull rod that is slidably connected to the inner side of the rod body.

The fixing cones have two protrusions on their outer sides. The connecting ring is rotatably connected to the fixing block and does not detach. Each set of fixing cones includes multiple cones.

[0009] Preferably, a stop block for blocking the connecting rod is fixedly connected to the outside of the rod body and to the side of the fixing hole.

[0010] Preferably, multiple soil-breaking strips are fixedly connected to the bottom edge of the rod.

[0011] Preferably, a plurality of limiting strips are fixedly connected to the inner side of the rod, and the limiting strips are slidably connected to the pull rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a reinforcing anchor for embankment slope construction, including an anchor body 1, a fixing block 2 screwed to the outside of the anchor body 1, a fixing component for reinforcing the slope installed on the outside of the fixing block 2, an anti-detachment component for preventing the anchor body 1 from detaching installed on the outside of the anchor body 1 near the end, a driving component for opening and closing the anti-detachment component installed on the inside of the anchor body 1, and a plurality of soil-breaking strips 14 fixedly connected to the bottom edge of the anchor body 1.

[0024] In addition, the end of the pole 1 is tapered, and the multiple soil-breaking strips 14 on the outer side of the end of the pole 1 can facilitate the pole 1 to cut through the soil and enter the soil. The fixing block 2 is a frustum ring, and the fixing block is screwed on the outer side of the pole 1 to increase the contact area of ​​the pole 1 to squeeze the slope. The driving component can drive the anti-detachment component to open and close, so as to facilitate the insertion of the pole 1 into the soil and increase the contact area of ​​the pole 1. At the same time, it can also facilitate the subsequent disassembly and removal of the pole 1.

[0025] Specifically, the anti-detachment component includes a pull rod 3 that is slidably connected to the inner side of the rod body 1. Multiple circumferentially arranged fixing holes 4 are opened on the outer side of the rod body 1 near the bottom. A fixing shaft 5 is fixedly connected to the inner side of the fixing holes 4. A connecting rod 6 is hinged to the outer side of the fixing shaft 5. The pull rod 3 is hinged to the connecting rod 6. An anti-detachment plate 7 is fixedly connected to the outer side of the multiple connecting rods 6 by bolts. The anti-detachment plate 7 is made of rubber. The driving component includes a lead screw 8 that is rotatably connected to the top of the pull rod 3. A limit part 9 is fixedly connected to the end of the lead screw 8. Multiple limit strips 15 are fixedly connected to the inner side of the rod body 1. The limit strips 15 are slidably connected to the pull rod 3. A stop block 13 for blocking the connecting rod 6 is fixedly connected to the outer side of the rod body 1 on one side of the fixing holes 4. The limit part 9 is rotatably connected to the pull rod 3 and does not detach. The lead screw 8 passes through the rod body 1 and is screwed to it.

[0026] The lead screw 8 can be screwed to the end of the rod body 1, so that the lead screw 8 drives the pull rod 3 to slide up and down inside the rod body 1 through the limiting part 9. Multiple limiting strips 15 can guide and limit the pull rod 3 to prevent the pull rod 3 from deviating. The pull rod 3 can drive the connecting rod 6 to rotate hingedly outside the fixed shaft 5. The fixing hole 4 can provide the connecting rod 6 with a space for movement. The connecting rod 6 can drive the anti-detachment plate 7 to expand and contract. Multiple stops 13 can support the connecting rod 6 to prevent the connecting rod 6 from expanding excessively and increase the strength of the connecting rod 6 in supporting the expansion of the anti-detachment plate 7. The anti-detachment plate 7 can increase the contact area between the rod body 1 and the soil and improve the stability of the rod body 1 in reinforcing the slope soil.

[0027] More specifically, the fastener includes a connecting ring 10 embedded at the outer edge of the fixing block 2. Two sets of circumferentially arranged fixing cones 11 are fixedly connected to the outer side of the connecting ring 10. Two protrusions 12 are provided on the outer side of the fixing cones 11. The connecting ring 10 is rotatably connected to the fixing block 2 and does not detach. Each set of fixing cones 11 includes multiple cones.

[0028] Furthermore, the fixing block 2 rotates screwed on the outside of the rod body 1, and then the fixing block 2 pushes multiple fixing cones 11 into the soil through the connecting ring 10. The two protrusions 12 on the outside of the fixing cones 11 can increase the contact area between the fixing cones 11 and the soil, so that the rod body 1 can reinforce the slope through the fixing block 2 and the anti-detachment plate 7, thereby improving the stability and practicality of the rod body 1 in reinforcing the slope.

[0029] Working principle: First, the rod 1 is inserted into the soil. Then, multiple soil-breaking strips 14 at the end of the rod 1 break the soil. Then, multiple blocks 13 squeeze the soil. Then, the screw 8 is rotated. At this time, the screw 8 drives the pull rod 3 to slide upward inside the rod 1 through the limiting part 9. At the same time, the limiting strip 15 slides outside the pull rod 3. At this time, the pull rod 3 drives the connecting rod 6 to expand around the fixed shaft 5. At the same time, multiple connecting rods 6 drive the anti-detachment plate 7 to expand. Then, the fixing block 2 is screwed and rotated in the rod 1. Then, the fixing block 2 is inserted into the soil through the fixing cone 11 outside the connecting ring 10. At the same time, the protrusion 12 on the outside of the fixing cone 11 is embedded in the soil, so that the fixing block 2 and the anti-detachment plate 7 reinforce and fix the slope through the rod 1.
