Description

Technical Field

Common types of support structures include: gravity retaining wall, buttress retaining wall, cantilever support, plate rib or lattice anchor retaining wall support, pile anchor retaining wall support, anchor spraying support, etc. According to the stress transfer method, anchor rods can be divided into tension anchor rods and pressure anchor rods. The anchor rod body of the tension anchor rod is directly bonded to the grouting body, and the anchoring between the anchor rod and the soil is achieved through the bonding force between the anchor rod body and the grouting body; the pressure anchor rod can convert the tension of the anchor rod body into the pressure of the grouting body, making full use of the good compressive resistance of the grouting body, applying compressive stress to the grouting body through the bearing body, so that the grouting body and the surrounding rock and soil body produce friction resistance to provide the bearing capacity required by the anchor rod.

[0003] At present, when using anchor rods, it is necessary to insert the anchor rods into the soil layer, and then pour slurry into the anchor rods, so that the slurry enters the installation hole between the anchor rods and the soil layer along the anchor rod through hole, so that the slurry can wrap the anchor rods, and after the slurry solidifies, the anchor rods can be fully in contact with the soil layer, thereby achieving the purpose of anchoring.

The first cavity 13 is arranged along the length direction of the anchor rod 1, and a plurality of second cavities 14 are arranged, and are symmetrically distributed on both sides of the first cavity 13; a power component 2 is arranged inside the first cavity 13, and an anchor component 3 and a reinforcement component 4 are arranged inside each second cavity 14. Anchor holes 12 for the anchor component 3 to extend out of the anchor rod 1 and reinforcement holes 11 for the reinforcement component 4 to extend out of the anchor rod 1 are correspondingly opened on the surface of the anchor rod 1; the power component 2 is used to provide power to the anchor component 3 and the reinforcement component 4.

[0034] When the anchor rod 1 is installed, the anchor rod 1 is installed inside the installation hole 10, and then the power component 2 starts to work. Under the action of the power component 2, power can be provided to the anchor component 3, so that the anchor component 3 extends out of the anchor hole 12 on the surface of the anchor rod 1 along the second cavity 14, and extends into the soil layer 9. In this way, the anchoring area of ​​the anchor rod 1 can be increased, and the anchor rod 1 and the surrounding soil have a higher embedding strength, thereby improving the anchoring force and reliability of the anchor rod 1; at the same time, the movement of the anchor component 3 also drives the reinforcement component 4 to work, so that the reinforcement component 4 also extends out of the reinforcement hole 11 on the surface of the anchor rod 1 along the second cavity 14, and penetrates into the soil layer 9. At the same time, with the cooperation of the jacking component 17, it is convenient for the reinforcement component 4 to be opened, so that the anchoring area of ​​the anchor rod 1 can be further increased, thereby improving the anchoring effect.

[0035] The 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 upper and lower ends are rotatably connected to the anchor rod 1. The upper end of the rotating shaft 201 is fixedly connected to the rotating block 202, and the rotating block 202 is rotatably connected to the anchor rod 1. The rotating block 202 extends to the top end surface of the anchor rod 1, and a hexagonal groove 203 is provided on the upper end surface of the rotating block 202; a first bevel gear 204 is fixedly connected to the rotating shaft 201 at a position corresponding to each second cavity 14, and a second bevel gear 205 is meshed at a position corresponding to each second cavity 14 on both sides of the first bevel gear 204. The anchor assembly 3 includes a threaded rod 301 and an anchor rod 302. The anchor rod 302 is located in the second cavity 14, with one end facing the anchor hole 12 downward, 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 anchor rod 302, and the end facing the anchor hole 12 is a conical tip. One end of the threaded rod 301 is embedded in the threaded hole of the anchor rod 302 and is threadedly connected with the anchor rod 302. The other end passes through the second cavity 14, extends into the first cavity 13, and is connected with the corresponding second bevel gear 205. Since the cross section of the anchor rod 302 is circular, the anchor hole 12 is a circular hole, and its diameter matches the anchor rod 302. The anchor hole 12 is connected to the second cavity 14 and corresponds to the anchor rod 302. When working, by setting the anchor hole 12, the anchor rod 302 is convenient to extend out of the anchor rod 1 under the action of the anchor hole 12. A limiting groove 16 is provided on the inner wall of the second cavity 14, 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. When working, the movement of the anchor rod 302 can be limited by setting the limiting groove 16 and the limiting block 15, so that the anchor rod 302 can only move horizontally.

[0036] In the embodiment, the working process of the anchoring assembly is: inserting the hexagonal wrench into the hexagonal groove 203 of the rotating block 202, and then rotating the rotating block 202, then the rotating shaft 201 can be driven to rotate, and the rotation of the rotating shaft 201 drives the first bevel gear 204 to rotate, and then the first bevel gear 204 and the second bevel gear 205 cooperate to provide power for the movement of the anchoring assembly 3; with the rotation of the second bevel gear 205, the threaded rod 301 can be driven to rotate, and since the anchoring rod 302 is threadedly connected to the threaded rod 301, when the thread rotates, the anchoring rod 302 is driven to slide inside the second cavity 14, and the anchoring rod 302 can extend along the corresponding anchoring hole 12, move toward the inside of the soil layer 9, and be inserted into the inside of the soil layer 9, thereby increasing the anchoring area of ​​the anchor rod 1, so that the anchor rod 1 has a higher embedding strength with the surrounding soil, thereby improving the anchoring force and reliability of the anchor rod 1.

[0037] In the embodiment, 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, and a rotating seat 401 is fixedly installed on the upper and lower tails of the anchor rod 302 away from the conical tip, each reinforcement rod 402 is rotatably connected to the corresponding rotating seat 401, and one 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, and the two first connecting blocks 404 are respectively located on the upper and lower sides of the anchor hole 12, and a second connecting block 405 is provided on the side of the middle part of each reinforcement rod 402 adjacent to the anchor rod 302, and 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 anchor hole 12 is symmetrically provided with two reinforcement holes 11 above and below, and the reinforcement holes 11 are vertical strips, and their width matches the diameter of the reinforcement rod 402. The tip of each reinforcement rod 402 faces the corresponding reinforcement hole 11, and when the anchor rod 302 moves horizontally toward the anchor hole 12, the upper and lower reinforcement rods 402 can extend the anchor rod 1 from the two reinforcement holes 11 respectively.

[0038] During the outward movement of the anchor rod 302, the two reinforcement rods 402 are also driven 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 reinforcement rod 402 can be extended and opened at the same time, so that the reinforcement rod 402 extends obliquely from the corresponding reinforcement hole 11 and extends into the soil layer 9. This can further increase the anchoring area of ​​the anchor rod 1, thereby improving the anchoring effect.

[0039] In order to make it easier to open the reinforcement rod 402, a lifting assembly 17 is provided between the anchor rod 302 and the reinforcement rod 402. Figure 7 and Fig.11 As shown, the lifting assembly 17 includes a circular groove 1701, a spring 1702, an extension tube 1703 and a lifting rod 1704. The circular groove 1701 is opened on the circumferential surface of the anchor rod 302, and the circular groove 1701 corresponds to the reinforcement rod 402. The circumferential surface of the anchor rod 302 is fixedly connected with the extension tube 1703, and the extension tube 1703 is aligned with the circular groove 1701. The lifting rod 1704 is slidably connected inside the extension tube 1703; the circular groove 1701 is fixedly connected with the spring 1702, and the end of the spring 1702 away from the bottom of the circular groove 1701 is fixedly connected to the lifting rod 1704. When working, as the anchor rod 302 is extended, the reinforcement rod 402 no longer presses the lifting rod 1704, and then the lifting rod 1704 can be driven out under the action of the compression spring 1702, thereby lifting the reinforcement rod 402, which is conducive to the opening of the reinforcement rod 402.

[0040] The embodiment provides a geotechnical engineering slope anchoring support structure, such as Figure 1 and Figure 2 As shown, the upper circumferential surface of the anchor rod 1 is fixedly connected with a fixing plate 5, and there are four fixing plates 5, which are arranged in a circumferential array, and the lower end of the reinforcement rod is fixedly connected with an insertion rod 6; during operation, when the anchor rod 1 is installed inside the installation hole 10, after the insertion rod 6 contacts the soil layer 9, the anchor rod 1 is continued to be pressed, 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 of 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. Figure 4 and Figure 8 As shown, two pouring channels 7 are provided on the upper end surface of the anchor rod 1, and a plurality of through holes 8 are provided on the circumferential surface of the anchor rod 1, and the through holes 8 and the pouring channels 7 are both connected to the first cavity 13. During operation, when it is necessary to pour slurry, the slurry is poured into the first cavity 13 through the pouring channels 7, and then enters the mounting hole 10 through the through holes 8, thereby achieving the purpose of pouring slurry. After the slurry solidifies, the anchoring effect between the anchor rod 1 and the soil layer 9 can be further improved.

[0041] The construction process of the present invention is as follows: when installing the anchor rod 1, the anchor rod 1 is installed inside the installation hole 10. After the insertion rod 6 contacts the soil layer 9, the anchor rod 1 is continued to be pressed, 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 of 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 insert the hexagonal wrench into the hexagonal groove 203 of the rotating block 202, control the rotation of the rotating block 202, and rotate the rotating shaft 201, while driving multiple roots. The anchor rod 302 slides inside the corresponding second cavity 14, so that the tip of the anchor rod 302 extends out along the corresponding anchor hole 12 and is inserted into the soil layer 9, thereby increasing the anchoring area of ​​the anchor rod 1, making the anchor rod 1 have a higher embedding strength with the surrounding soil, and improving the anchoring force and reliability of the anchor rod 1; in the process of the anchor rod 302 moving outward, the two reinforcement rods 402 are also driven to move outward, and in the process of movement, the reinforcement rod 402 is extended and opened at the same time, so that the reinforcement rod 402 is obliquely extended out of the corresponding reinforcement hole 11 and inserted into the soil layer 9, thereby further increasing the anchoring area of ​​the anchor rod 1, thereby improving the anchoring effect. After the anchor rod 302 and the reinforcement rod 402 are inserted into the soil layer and fixed, the slurry is poured through the two pouring channels 7 on the end face of the anchor rod 1, and the slurry is poured into the first cavity 13 through the pouring channel 7, and then enters the installation hole 10 through the through hole 8, thereby achieving the purpose of pouring the slurry. After the slurry 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 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 aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
