[0001] This invention relates to the field of ground anchor reinforcement technology, and in particular to a ground anchor structure that is not easily detached. Background Technology

[0002] Ground anchors can be divided into anchor piles, anchor points, anchor ingots, and drag pits. Ground anchors are commonly used in lifting operations to fix drag ropes, guy ropes, winches, guide pulleys, etc. Ground anchors are generally made by embedding steel wire ropes, steel pipes, precast reinforced concrete components, round logs, etc. into the ground.

[0003] A search revealed that the patent, CN219195945U, entitled "A Utility Model of a Novel Ground Anchor Structure," includes a fixing component, a positioning ring disposed on the fixing component, and a fixing rod disposed on the positioning ring. Research and analysis revealed that although it facilitates angle adjustment according to the needs of steel mold installation, it also has the following drawbacks to a certain extent.

[0004] For example, the structure mainly focuses on innovative improvements to the hoisting components above the pre-embedded parts. The installation stability of the pre-embedded parts anchored into the ground at the bottom is generally poor, and it does not have the function of expansion and reinforcement. The bottom installation stability is generally poor, and it is impossible to carry out side reinforcement treatment. The overall linkage of the structure is also generally poor. In order to solve the above technical problems, we designed a ground anchor structure that is not easy to fall off. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ground anchor structure that is not easily detached, comprising a mounting base, a storage shell fixedly mounted at the center of the bottom of the mounting base, insertion holes through the four corners of the top of the mounting base, auxiliary positioning and reinforcement mechanisms mounted on the sides of the mounting base, angle-changing reinforcement mechanisms mounted on the left and right sides of the top of the mounting base, and a penetration reinforcement mechanism through the center of the top of the mounting base. The penetration reinforcement mechanism includes a main anchor rod and a sleeve, a frustum tray fixedly mounted on the top of the surface of the main anchor rod, and auxiliary positioning and reinforcement mechanisms including an auxiliary shell and auxiliary anchor rods, four of each. The top of the auxiliary shell is fixedly connected to the bottom of the mounting base, the auxiliary anchor rod is slidably mounted through the insertion hole, a crossbar is slidably mounted through the inner cavity of the auxiliary shell, a spring is sleeved on the surface of the crossbar, a locking block is fixedly connected to the outer end of the crossbar, and an inclined plate is fixedly connected to the inner end of the crossbar. One end of the spring is connected to... The crossbar is fixedly connected to the surface, and the other end of the spring is fixedly connected to the inner wall of the auxiliary shell. The inclined plate, on the side away from the crossbar, penetrates the inner cavity of the housing and contacts the frustum tray. The surface of the auxiliary anchor rod is provided with a slot for engaging the locking block. An installation bolt is installed through the top of the auxiliary anchor rod. A threaded groove is provided on the top of the auxiliary anchor rod. A stud is threaded into the inner cavity of the threaded groove. A second anchor ring is welded to the top of the stud. The variable angle reinforcement mechanism includes a housing groove and a fixing frame. The housing groove is opened laterally on the top of the mounting base. The bottom of the fixing frame is fixedly connected to the top of the mounting base. A movable plate is movably fitted on the surface of the fixing frame. Rotating side plates are movably installed on both the front and rear sides of the movable plate. A pressing bolt is threaded at the center of the movable plate. Positioning holes are opened through the inner cavity of the housing groove and the surface of the rotating side plates in the front and rear directions. An anti-loosening screw is installed through the inner cavity of the positioning hole. An anti-loosening nut is threaded on the rear side of the anti-loosening screw.

[0007] Preferably, the main anchor rod is slidably installed at the center of the top of the mounting base plate, the frustum tray is adapted to the storage shell, and a disc-shaped sleeve is fixedly fitted on the surface of the main anchor rod and inside the cavity of the shell.

[0008] Preferably, an elastic vibration strip is embedded in the inner wall of the casing, an elastic expansion strip is fixedly installed at the bottom of the casing, a pressure block is welded to the bottom of the main anchor rod and located at the bottom of the casing, and a soil-breaking cone is welded to the center of the bottom of the pressure block.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention has the advantage of convenient angle adjustment by setting up a variable angle reinforcement mechanism. It can flexibly adjust the angle of the movable plate and the rotating side plate to cooperate with the anti-loosening screw and the anti-loosening nut for positioning and installation.

The present invention has the advantage of bottom reinforcement by setting an insertion reinforcement mechanism. When the main anchor rod is moved up for installation, the bottom installation area of ​​the elastic expansion strip is expanded by the pressure block, and the disc-shaped sleeve contacts the elastic vibration strip, so that the elastic vibration strip vibrates continuously, which helps to rearrange the particles in the landfill soil, reduce voids, and improve the compaction of the landfill soil. 3. This invention, by setting up a frustum tray, an auxiliary positioning and reinforcement mechanism, and a storage shell, has the function of side reinforcement. Multiple auxiliary anchor rods can be inserted and installed to ensure the stability of the mounting base. When the frustum tray moves upward, it abuts into the storage shell, causing the locking block to move outward to position and lock the auxiliary anchor rods, further improving the overall stability of the structure.

One end of the spring 411 is fixedly connected to the surface of the crossbar 410, and the other end of the spring 411 is fixedly connected to the inner wall of the auxiliary shell 408. Please refer to the figure. Figure 3 , Figure 6 and Figure 7 The inclined plate 409, on the side away from the crossbar 410, penetrates the inner cavity of the storage shell 5 and contacts the frustum tray 302. The surface of the auxiliary anchor rod 403 is provided with a slot 404 for use with the locking block 407. Please refer to the figure. Figure 3 , Figure 6 and Figure 7 An installation bolt 402 is installed through the top of the auxiliary anchor rod 403. A threaded groove 405 is opened on the top of the auxiliary anchor rod 403. A stud 406 is threadedly connected to the inner cavity of the threaded groove 405. A second anchor ring 401 is welded to the top of the stud 406. Please refer to the figure. Figure 1 and Figure 5 The angle-reinforcing mechanism 2 includes a storage slot 201 and a fixing frame 205. The storage slot 201 is horizontally opened on the top of the mounting base plate 1. The bottom of the fixing frame 205 is fixedly connected to the top of the mounting base plate 1. A movable plate 203 is movably sleeved on the surface of the fixing frame 205. Please refer to the figure. Figure 1 and Figure 5 Rotating side plates 206 are movably installed on both the front and rear sides of the surface of the movable plate 203, and a pressing bolt 202 is threadedly connected at the center of the surface of the movable plate 203. Please refer to the figure. Figure 1 and Figure 5 The inner cavity of the storage slot 201 and the surface of the rotating side plate 206 are provided with positioning holes 207 extending through from front to back. The inner cavity of the positioning hole 207 is provided with an anti-loosening screw 208, and the rear side of the anti-loosening screw 208 is threaded with an anti-loosening nut 209. Please refer to the figure. Figure 3 and Figure 4 The main anchor rod 301 is slidably installed at the center of the top of the mounting base plate 1. The frustum tray 302 is adapted to the storage shell 5. The surface of the main anchor rod 301 and the inner cavity of the sleeve 308 are fixedly fitted with a disc-shaped sleeve 303. Please refer to the figure. Figure 3 and Figure 4 The inner wall of the casing 308 is inlaid with an elastic vibration strip 307, the bottom of the casing 308 is fixedly installed with an elastic expansion strip 306, the bottom of the main anchor rod 301 and located at the bottom of the casing 308 are welded with a pressure block 304, and the center of the bottom of the pressure block 304 is welded with a soil breaking cone 305. Please refer to the figure. Figure 3 and Figure 4 The number of disc-shaped sleeves 303 is several and they are evenly distributed on the main anchor rod 301. The outer diameter of the disc-shaped sleeves 303 is smaller than the inner diameter of the sleeve 308. This design is used to provide space for elastic deformation of the inner end of the elastic vibration strip 307. The pressing block 304 is shaped like a frustum, which can compress multiple elastic expansion strips 306 to expand outward when it moves upward. The elastic expansion strips 306 are evenly pressed into the soil, further improving the overall stability of the structure. The elastic vibration strip 307 is made of stainless spring steel, and a rubber strip is embedded at the connection with the housing 308. The presence of the rubber strip can meet the vibration space requirements of the elastic vibration strip 307 and prevent the elastic vibration strip 307 from detaching from the housing 308. The storage slot 201 has several positioning holes 207, which can be aligned with the positioning holes 207 on the rotating side plate 206 when the movable plate 203 rotates at different angles. In addition, the rotating side plate 206 can be positioned and installed in conjunction with the anti-loosening screw 208 and the anti-loosening nut 209. When the anti-compression bolt 202 is installed, it contacts and tightens with the main anchor rod 301. This installation method can effectively improve the installation stability of the main anchor rod 301 and the movable plate 203, prevent the movable plate 203 from rotating at will, and prevent the main anchor rod 301 from moving down at will. The top of the mounting base plate 1 and the outer ring of the insertion hole 6 are provided with screw holes for use with mounting bolts 402, so that the auxiliary anchor rod 403 can be fastened to the mounting base plate 1 by mounting bolts 402. By setting the storage slot 201, the space requirement for inserting one end of the rotating side plate 206 can be met, and the requirement for opening multiple positioning holes 207 can be met. By setting the pressing bolt 202, it can be threadedly connected to the movable plate 203, and can contact and abut against the main anchor rod 301 in the installation state, thereby improving the overall stability of the structure. By setting the fixed frame 205, the movable plate 203 can be installed in a movable manner. By setting the rotating side plate 206, it can cooperate with the fixed frame 205 to form a triangular stable structure in the installed state, ensuring the installation stability of the first anchor ring 204. By setting a positioning hole 207, an anti-loosening screw 208, and an anti-loosening nut 209, the anti-loosening screw 208 can pass through the positioning hole 207 to position one end of the rotating side plate 206, and the anti-loosening nut 209 can be screwed in to ensure the installation stability of the anti-loosening screw 208. By setting up a frustum tray 302, an inclined plate 409 and a storage shell 5, when the frustum tray 302 moves up into the storage shell 5, multiple inclined plates 409 can be pressed outwards simultaneously, causing the inclined plates 409 to drive the locking block 407 to move outwards together. By setting up a disc-shaped sleeve 303 and an elastic vibration strip 307, when the disc-shaped sleeve 303 moves upward and contacts and separates from the elastic vibration strip 307, the inner end of the elastic vibration strip 307 vibrates up and down at a high frequency, and transmits the vibration to the outer end of the elastic vibration strip 307, thereby helping to improve the compaction of the backfill soil on the outside of the casing 308. By setting up the pressing block 304 and the elastic expansion bar 306, multiple elastic expansion bars 306 can be expanded outward to press up when the pressing block 304 moves upward, increasing the bottom installation area of ​​the insertion reinforcement mechanism 3 and improving the overall stability of the structure. By setting up the mounting bolt 402, it can cooperate with the screw hole on the mounting base plate 1 to stably install the auxiliary anchor rod 403 on the mounting base plate 1. By setting the auxiliary anchor rod 403 and the insertion hole 6, the positioning and installation functions can be achieved, making it convenient for workers to accurately nail the auxiliary anchor rod 403 into the soil. By setting the slot 404 and the locking block 407, the positioning and locking functions can be achieved, and the auxiliary anchor rod 403 can be prevented from moving up and down randomly during installation. By setting the threaded groove 405 and the stud 406, a threaded connection can be achieved, making the second anchor ring 401 detachable, which facilitates the subsequent replacement and installation of the second anchor ring 401. By setting the auxiliary shell 408, the left and right displacement of the crossbar 410 can be guided, and the installation requirements of the spring 411 can be met. By setting the spring 411, the crossbar 410 can be provided with an elastic restoring force, preventing the crossbar 410 from moving arbitrarily.

[0013] A method for using a ground anchor structure that is not easily detached includes the following steps: A: The anchor is pre-installed. The insertion reinforcement mechanism 3, the mounting base plate 1, and the auxiliary anchor rod 403 are designed separately. First, a pit is dug at a suitable location. Then, the soil-breaking cone 305 is lowered and nailed into the bottom of the pit to ensure the verticality of the casing 308. Soil is filled in, and the casing 308 is knocked down to make it move down in the soil. At the same time, the inner end of the elastic vibration strip 307 moves down and contacts the disc-shaped sleeve 303. Its outer end provides auxiliary vibration to the backfill soil to improve the compaction of the backfill soil. As the casing 308 moves down, the elastic expansion strip 306 contacts the pressing block 304 and automatically expands outward to penetrate into the soil, increasing the bottom installation area and ensuring the installation stability of the insertion reinforcement mechanism 3. Then, the workers need to compact the soil again, and the soil should cover the casing 308. B: Side reinforcement. First, adjust the position of the mounting base plate 1 so that the housing 5 on the mounting base plate 1 is aligned with the frustum tray 302. Then, move the mounting base plate 1 down so that the frustum tray 302 enters the housing 5. At this time, leave a certain installation gap between the main anchor rod 301 and the housing 5. Then, nail the auxiliary anchor rod 403 through the auxiliary positioning and reinforcement mechanism 4 into the soil. Due to the design of the top of the auxiliary anchor rod 403, when the bottom of the auxiliary anchor rod 403 is nailed into the soil, it will drive the auxiliary anchor rod 401 again. 3. The downward movement will cause the mounting base plate 1 to move downward synchronously. The frustum tray 302 enters the storage shell 5 and fits into the storage shell 5. The slot 404 is aligned with the block 407. When the frustum tray 302 is introduced into the storage shell 5, multiple inclined plates 409 are squeezed and displaced outward. The block 407 is inserted into the slot 404, and the spring 411 is compressed to prevent the auxiliary anchor rod 403 from moving up and down at will. Then, the mounting bolt 402 is screwed in to reinforce the auxiliary anchor rod 403 on the mounting base plate 1. C: Flexible angle adjustment. According to the actual engineering requirements for anti-slip, anti-collapse, anti-tilting or anti-buoyancy, the position of the rotating side plate 206 in the receiving groove 201 is adjusted, and the movable plate 203 is rotated simultaneously to adjust the angle of the first anchor ring 204. After the adjustment is completed, the anti-loosening screw 208 is passed through the positioning hole 207 and the rotating side plate 206 and locked with the anti-loosening nut 209. The movable plate 203 and the rotating side plate 206 form a stable triangle, and the pressing bolt 202 is screwed in to press against the main anchor rod 301 to ensure the stability of the position of the first anchor ring 204. D: Steel cable assembly. The steel cable to be pulled is divided into two strands, both of which converge from the second anchor ring 401 to the first anchor ring 204. At this time, the two strands of steel cable will form a triangular pulling structure to ensure pulling stability and better meet the engineering requirements.

[0014] In summary, this non-detachable ground anchor structure, by setting up an installation base plate 1, a variable angle reinforcement mechanism 2, an insertion reinforcement mechanism 3, an auxiliary positioning reinforcement mechanism 4, and a housing shell 5, solves the problems of the general installation stability of the pre-embedded parts anchored into the ground at the bottom of the structure, the lack of expansion reinforcement function, the general installation stability at the bottom, the inability to carry out side reinforcement treatment, and the general overall linkage of the structure.
