A geotechnical engineering slope anchoring and supporting structure

Abstract

This invention provides a slope anchoring support structure for geotechnical engineering. The support structure includes anchor rods and a soil layer. Installation holes are formed on the surface of the soil layer, and the anchor rods are installed inside these holes. Each anchor rod contains a first cavity and a second cavity, with multiple second cavities. A power assembly is housed within the first cavity, and an anchoring assembly is housed within the second cavity. The power assembly provides power to the anchoring assembly. By incorporating the power assembly and anchoring assembly, after the anchor rod is inserted into the pre-drilled installation hole in the soil layer, the power assembly operates, providing power to the anchoring assembly. This allows the anchoring assembly to extend into the soil layer, increasing the anchoring area of ​​the anchor rod and resulting in higher embedment strength between the anchor rod and the surrounding soil. This improves the anchoring force and reliability of the anchor rod. Furthermore, with the assistance of reinforcement components, the anchoring area can be further increased, thereby enhancing the anchoring effect.

Description

Technical Field

[0001] This invention relates to the field of slope anchoring and support technology, and in particular to a slope anchoring and support structure for geotechnical engineering. Background Technology

[0002] Slope protection refers to the measures taken to support, reinforce, and protect slopes to ensure their safety and that of their environment. Commonly used support structures include: gravity retaining walls, buttress retaining walls, cantilever supports, plate-ribbed or lattice-type anchored retaining walls, pile-type anchored retaining walls, and shotcrete anchoring. Based on the stress transfer method, anchors can be divided into tension anchors and compression anchors. Tension anchors are directly bonded to the grout, achieving anchoring between the anchor and the soil through the bond force between the anchor and the grout. Compression anchors convert the tension of the anchor body into pressure in the grout, fully utilizing the good compressive strength of the grout. The bearing capacity applies compressive stress to the grout, creating frictional resistance between the grout and the surrounding soil and rock, thus providing the required bearing capacity for the anchor.

[0003] Currently, when using anchor bolts, the bolts need to be inserted into the soil layer, and then grout is poured into the bolt. The grout enters the installation hole between the bolt and the soil layer through the bolt's through-hole, thus encapsulating the bolt. After the grout solidifies, the bolt makes full contact with the soil layer, achieving anchoring. However, because the contact area between the bolt and the soil layer is small, the anchoring performance is poor, and the mechanical strength is low. Therefore, the pull-out resistance is low, resulting in poor anchoring force and reliability. Thus, a geotechnical engineering slope anchoring support structure needs to be designed. Summary of the Invention

[0004] This invention addresses the problems existing in the prior art by providing a geotechnical engineering slope anchoring support structure. This support structure adds anchoring components to the anchor rods, including components that can increase the anchoring area of ​​the anchor rods, thereby increasing the embedment strength between the anchor rods and the surrounding soil, improving the anchoring force and reliability of the anchor rods, and thus improving the anchoring effect.

Reinforcement holes communicating with the second cavity are respectively provided on the upper and lower sides of each anchor hole on the outer wall of the anchor rod. When the rotating shaft drives the anchor rod to move, it simultaneously drives the two reinforcement rods connected to it to move towards the outer wall of the anchor rod, extend out of the corresponding reinforcement holes, and insert into the soil layer.

[0009] A preferred technical solution of the present invention is as follows: one or more casting channels are provided on the upper end face of the anchor rod, and multiple through holes are provided on the circumferential surface of the anchor rod.

The two first connecting blocks are located on the upper and lower sides of the anchor hole, respectively. A second connecting block is provided on the side of the middle of each reinforcement rod near the anchor rod. The second connecting block is fixedly connected to the reinforcement rod. One end of each transmission rod is rotatably connected to the first connecting block, and the other end is rotatably connected to the second connecting block.

[0015] A preferred technical solution of the present invention is as follows: a lifting assembly is provided between the anchoring assembly and the reinforcing rod.

Under the action of the power component, power can be provided to multiple sets of anchoring components at the same time, so that multiple sets of anchoring components can be inserted into the soil layer at the same time. This can increase the anchoring area of ​​the anchor rod, make the anchor rod and the surrounding soil have higher embedment strength, and improve the anchoring force and reliability of the anchor rod.

[0018] (2) Each set of anchoring components of the present invention is provided with two sets of reinforcing components. The reinforcing components include a rotating seat, a reinforcing rod, a transmission rod, a first connecting block and a second connecting block.

This can further increase the anchoring area of ​​the anchoring rod, thereby improving the anchoring effect.

[0019] (3) The present invention also provides grouting holes on the anchor rod, which lead to the first cavity, and provides multiple sets of through holes on the anchor rod wall, so that grouting can be performed again after the anchor rod is fixed to ensure the overall anchoring effect of the anchor rod.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] An embodiment provides a geotechnical engineering slope anchoring support structure, such as Figures 1 to 11 As shown, the structure includes an anchor rod 1 and a soil layer 9. An installation hole 10 is formed on the surface of the soil layer 9. The anchor rod 1 is installed inside the installation hole 10. The anchor rod 1 has a first cavity 13 and a second cavity 14 inside. The first cavity 13 is arranged along the length of the anchor rod 1. Multiple second cavities 14 are provided and symmetrically distributed on both sides of the first cavity 13. A power assembly 2 is provided inside the first cavity 13. An anchoring assembly 3 and a reinforcement assembly 4 are provided inside each second cavity 14. An anchoring hole 12 for the anchoring assembly 3 to extend out of the anchor rod 1 and a reinforcement hole 11 for the reinforcement assembly 4 to extend out of the anchor rod 1 are correspondingly formed on the surface of the anchor rod 1. The power assembly 2 provides power to the anchoring assembly 3 and the reinforcement assembly 4.

[0034] During the installation of anchor rod 1, anchor rod 1 is installed into the installation hole 10. Then, the power component 2 operates, providing power to the anchoring component 3. This causes the anchoring component 3 to extend out of the anchoring hole 12 on the surface of anchor rod 1 along the second cavity 14 and into the soil layer 9. This increases the anchoring area of ​​anchor rod 1, resulting in higher embedment strength between anchor rod 1 and the surrounding soil, thus improving the anchoring force and reliability of anchor rod 1. Simultaneously, the movement of the anchoring component 3 also drives the reinforcement component 4 to operate, causing the reinforcement component 4 to extend out of the reinforcement hole 11 on the surface of anchor rod 1 along the second cavity 14 and into the soil layer 9. With the assistance of the lifting component 17, the reinforcement component 4 can be opened, further increasing the anchoring area of ​​anchor rod 1 and improving the anchoring effect.

[0035] An embodiment provides a geotechnical engineering slope anchoring support structure, such as Figures 4 to 7As shown, the power assembly 2 includes a rotating shaft 201, a rotating block 202, a first bevel gear 204, and a second bevel gear 205. The rotating shaft 201 is vertically placed inside the first cavity 13, and both its upper and lower ends are rotatably connected to the anchor rod 1. The rotating block 202 is fixedly connected to the upper end of the rotating shaft 201, and the rotating block 202 is rotatably connected to the anchor rod 1. The rotating block 202 extends to the top surface of the anchor rod 1, and a hexagonal groove 203 is provided on the upper surface of the rotating block 202. The first bevel gear 204 is fixedly connected to the rotating shaft 201 at the position corresponding to each second cavity 14, and the second bevel gear 205 meshes on both sides of the first bevel gear 204 at the position corresponding to each second cavity 14. The anchoring assembly 3 includes a threaded rod 301 and an anchoring rod 302. The anchoring rod 302 is located inside the second cavity 14, with one end facing the anchoring hole 12 and the other end having a threaded hole. The length of the threaded hole is 1 / 2 to 2 / 3 of the length of the anchoring rod 302, and the end facing the anchoring hole 12 has a tapered tip. One end of the threaded rod 301 is embedded in the threaded hole of the anchoring rod 302 and threadedly connected to the anchoring rod 302. The other end passes through the second cavity 14, extends into the first cavity 13, and connects to the corresponding second bevel gear 205. Since the cross-section of the anchoring rod 302 is circular, the anchoring hole 12 is also circular, with a diameter matching that of the anchoring rod 302. The anchoring hole 12 communicates with the second cavity 14 and corresponds to the anchoring rod 302. During operation, by providing the anchoring hole 12, the anchoring rod 302 can easily extend out of the anchoring rod 1. The inner wall of the second cavity 14 has a limiting groove 16, and a limiting block 15 is slidably connected inside the limiting groove 16. The limiting block 15 is fixedly connected to the anchor rod 302. During operation, by setting the limiting groove 16 and the limiting block 15, the movement of the anchor rod 302 can be limited, so that the anchor rod 302 can only move horizontally.

[0036] In this embodiment, the working process of the anchoring component is as follows: a hexagonal wrench is inserted into the hexagonal groove 203 of the rotating block 202, and then the rotating block 202 is rotated. This will drive the rotating shaft 201 to rotate, and the rotation of the rotating shaft 201 will drive the first bevel gear 204 to rotate. In turn, the cooperation of the first bevel gear 204 and the second bevel gear 205 will provide power for the movement of the anchoring component 3. As the second bevel gear 205 rotates, the threaded rod 301 will rotate. Since the anchoring rod 302 is threadedly connected to the threaded rod 301, when the thread rotates, it will drive the anchoring rod 302 to slide inside the second cavity 14. The anchoring rod 302 can then extend along the corresponding anchoring hole 12, move towards the soil layer 9, and insert into the soil layer 9, increasing the anchoring area of ​​the anchor rod 1, so that the anchor rod 1 has a higher embedment strength with the surrounding soil, and improving the anchoring force and reliability of the anchor rod 1.

[0037] In the embodiments, such as Figure 6 and Figure 7As shown, the reinforcement component 4 includes two reinforcement rods 402 symmetrically arranged on the upper and lower sides of the anchor rod 302 and a transmission rod 403 located between each reinforcement rod 402 and the anchor rod 302. Rotating seats 401 are fixedly installed on the upper and lower ends of the anchor rod 302 away from the conical tip. Each reinforcement rod 402 is rotatably connected to the corresponding rotating seat 401, and the end of each reinforcement rod 402 away from the rotating seat 401 is pointed. Two first connecting blocks 404 are fixedly connected to the side of the second cavity 14 away from the first cavity 13. The two first connecting blocks 404 are located on the upper and lower sides of the anchor hole 12, respectively. A second connecting block 405 is provided on the side of the middle of each reinforcement rod 402 near the anchor rod 302. The second connecting block 405 is fixedly connected to the reinforcement rod 402. One end of each transmission rod 403 is rotatably connected to the first connecting block 404, and the other end is rotatably connected to the second connecting block 405. Each anchoring hole 12 is symmetrically provided with two reinforcing holes 11, and the reinforcing holes 11 are vertical strips with a width that matches the diameter of the reinforcing rod 402. The tip of each reinforcing rod 402 faces the corresponding reinforcing hole 11, and when the anchoring rod 302 moves horizontally toward the anchoring hole 12, the upper and lower reinforcing rods 402 extend out of the two reinforcing holes 11 respectively.

[0038] As the anchor rod 302 moves outward, it also drives the two reinforcing rods 402 to move outward. During the movement, with the cooperation of the rotating seat 401, the transmission rod 403, the first connecting block 404, and the second connecting block 405, the reinforcing rods 402 can extend and open at the same time, so that the reinforcing rods 402 extend obliquely out of the corresponding reinforcing holes 11 and into the soil layer 9. This can further increase the anchoring area of ​​the anchor rod 1, thereby improving the anchoring effect.

[0039] To facilitate the opening of the reinforcing rod 402, a lifting assembly 17 is provided between the anchor rod 302 and the reinforcing rod 402, such as... Figure 7 and Figure 11 As shown, the lifting assembly 17 includes a circular groove 1701, a spring 1702, an extension cylinder 1703, and a lifting rod 1704. The anchor rod 302 has a circular groove 1701 on its circumferential surface, which corresponds to the reinforcing rod 402. The extension cylinder 1703 is fixedly connected to the circumferential surface of the anchor rod 302, and the extension cylinder 1703 is aligned with the circular groove 1701. The lifting rod 1704 is slidably connected inside the extension cylinder 1703. The spring 1702 is fixedly connected inside the circular groove 1701. One end of the spring 1702 away from the bottom of the circular groove 1701 is fixedly connected to the lifting rod 1704. During operation, as the anchor rod 302 extends, the reinforcing rod 402 no longer holds the lifting rod 1704. Then, under the action of the compressed spring 1702, the lifting rod 1704 can be pushed out, thereby lifting the reinforcing rod 402, which is conducive to the opening of the reinforcing rod 402.

[0040] An embodiment provides a geotechnical engineering slope anchoring support structure, such as Figure 1 and Figure 2 As shown, a fixing plate 5 is fixedly connected to the upper circumferential surface of the anchor rod 1. Four fixing plates 5 are arranged in a circular array. An insertion rod 6 is fixedly connected to the lower end of each fixing plate. During operation, when the anchor rod 1 is installed into the mounting hole 10, after the insertion rod 6 contacts the soil layer 9, pressing the anchor rod 1 further inserts the insertion rod 6 into the soil layer 9. After the insertion rod 6 is inserted into the soil layer 9, the cooperation of the insertion rod 6 and the fixing plate 5 not only further increases the anchoring area between the anchor rod 1 and the soil layer 9, but also prevents the anchor rod 1 from rotating, facilitating the insertion of the anchor rod 302 into the soil layer 9. Figure 4 and Figure 8 As shown, two pouring channels 7 are opened on the upper end face of the anchor rod 1, and multiple through holes 8 are opened on the circumferential surface of the anchor rod 1. The through holes 8 and the pouring channels 7 are all connected to the first cavity 13. During operation, when it is necessary to pour grout, the grout is poured into the first cavity 13 through the pouring channels 7, and then enters the installation hole 10 through the through holes 8, thereby achieving the purpose of pouring grout. After the grout solidifies, the anchoring effect between the anchor rod 1 and the soil layer 9 can be further improved.

[0041] The construction process of this invention is as follows: When installing the anchor rod 1, the anchor rod 1 is installed into the installation hole 10. After the insertion rod 6 contacts the soil layer 9, the anchor rod 1 is pressed down further, so that the insertion rod 6 can be inserted into the soil layer 9. After the insertion rod 6 is inserted into the soil layer 9, the cooperation between the insertion rod 6 and the fixing plate 5 can not only further increase the anchoring area between the anchor rod 1 and the soil layer 9, but also prevent the anchor rod 1 from rotating, which is conducive to inserting the anchor rod 302 into the soil layer 9. Then, a hexagonal wrench is inserted into the hexagonal groove 203 of the rotating block 202 to control the rotation of the rotating block 202, the rotating shaft 201 rotates, and at the same time drives multiple anchor rods to rotate. The anchor rod 302 slides inside the corresponding second cavity 14, causing the tip of the anchor rod 302 to extend along the corresponding anchor hole 12 and insert into the soil layer 9, increasing the anchoring area of ​​the anchor rod 1 and giving the anchor rod 1 a higher embedment strength with the surrounding soil, thus improving the anchoring force and reliability of the anchor rod 1. As the anchor rod 302 moves outward, it also drives the two reinforcing rods 402 to move outward. During the movement, the reinforcing rods 402 extend and open at the same time, so that the reinforcing rods 402 extend obliquely out of the corresponding reinforcing hole 11 and insert into the soil layer 9, which can further increase the anchoring area of ​​the anchor rod 1, thereby improving the anchoring effect. After the anchor rod 302 and the reinforcing rod 402 are inserted into the soil layer and fixed, grout is poured through the two pouring channels 7 on the end face of the anchor rod 1. The grout is poured into the first cavity 13 through the pouring channels 7, and then enters the installation hole 10 through the through hole 8, thereby achieving the purpose of pouring grout. After the grout solidifies, the anchoring effect between the anchor rod 1 and the soil layer 9 can be further improved.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
