[0002] The subgrade slope is the sloping part on the side of the subgrade, connecting the subgrade main body with the natural ground. Its main functions are to maintain the stability of the subgrade, prevent the subgrade from deforming or collapsing due to lateral pressure, and also help to guide water flow and reduce the erosion of rainwater on the subgrade; When the common slope anchoring devices are currently in use, usually the approximate construction area is first determined on the slope, and simple drilling or piling is carried out as the anchoring foundation, and then the whole anchoring device is placed at the predetermined position and preliminarily fixed by basic fixing parts such as bolts; However, in this process, the ability to adjust the angle matching degree between the device and the slope surface is limited, it is difficult to ensure that the device array reaches the best stress angle with the slope surface, thus affecting the dispersion effect of the lateral pressure of the slope. In the stage of anchoring deep into the soil mass, in the face of the change of soil hardness at different depths, it cannot adapt and form a stable support, and it is very easy to have problems such as deviation and uneven stress when encountering hard soil layers; Therefore, in view of the above problems, a reinforcement device for subgrade slope construction is proposed.

[0008] Preferably, vertical plates are fixedly connected to both sides of the top end of the installation cover, an extension plate is fixedly connected to the outside of one of the vertical plates, and a sliding rod is fixedly connected to the outside of the other vertical plate.

[0009] The technical effects of adopting the above technical solution are as follows: Through the combination of the vertical plates, the extension plate and the sliding rod, multi-point fixation and multi-directional force application can be achieved, enhancing the stability of the installation cover and the entire device; the extension plate can provide additional connection points, facilitating connection with external support structures or adjacent devices, enhancing the synergy of the overall structure, and the sliding rod provides a basis for subsequent sliding adjustment or connection of other movable parts, improving the adaptability of the device.

[0010] Preferably, a slider is slidably connected inside the extension plate, one end of the sliding rod is fixedly connected to the slider, and an octagonal block is fixedly connected to the top end of the installation cover.

[0011] The technical effects of adopting the above technical solution are as follows: Through the sliding connection of the slider inside the extension plate, combined with the fixed connection between the sliding rod and the slider, the horizontal or vertical position adjustment of the sliding rod inside the extension plate can be achieved, thereby providing horizontal or vertical adjustability for the entire device, adapting to installation requirements of different widths or positions, and the setting of the octagonal block facilitates rotation operation through tools or manually.

[0021] The technical effects of adopting the above technical solution are as follows: The convex rod increases the contact area and the gripping force between the reverse nail rod and the soil body, and the limiting baffle restricts the telescopic range of the telescopic column to ensure its linear movement.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. The multi-layer telescopic sleeve adopts a nested structure. Each layer of the sleeve is matched with a locking pin through a limiting card slot. When the positioning column drills downward in a spiral manner, the sleeve extends step by step according to the soil hardness. When encountering a hard soil layer, the locking pin of the outer layer sleeve is triggered to pop out and engage with the inner layer card slot; designed in this way, the sleeve can respond to the soil changes in real time, maintain flexible follow-up in the soft soil layer and form a rigid support in the hard soil layer, ensuring that the positioning column always penetrates into the soil body in a vertical posture, reducing the downward drilling resistance while maintaining stability, and effectively solving the problem of skew caused by uneven stress of the traditional anchoring device in the hard soil layer; 2. The reverse nail rod drives the second rotating sliding column through the pulling column to generate a lever effect, and combines with the ball bearing of the inner rotating shaft to realize the directional expansion of the barbed convex rod. The barbs at its end bite with the soil through the wedging effect. With such a design, the barbed structure enhances the biting force between the soil and the device through mechanical wedging, forming an outward-expanded anchoring support, significantly improving the friction and uplift resistance between the device and the soil, and effectively solving the problem of anchoring failure caused by soil loosening or uneven stress. 3. Through the linkage design of the extension rope and the driving rotating block, when the extension rope is stretched, the driving rotating block slides circumferentially in the circular groove, and at the same time, the connecting bottom block and the connecting top block change the inclination angle of the device through overlapping adjustment. With such a design, construction workers can finely adjust the angle of each anchoring device according to the actual curvature of the slope, so that the device array fits the slope surface at the best stress angle, maximizing the contact area between the anchoring device and the slope, and avoiding local stress concentration caused by angle deviation.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 - 6 shown, this embodiment provides a technical solution: a reinforcement device for subgrade slope construction, including a connecting ring 1; A positioning and reinforcement assembly 2, the positioning and reinforcement assembly 2 includes multiple layers of telescopic sleeves 21 fixedly connected inside the connecting ring 1, a central ring 22 is fixedly connected inside the multiple layers of telescopic sleeves 21, a first thread groove 23 is opened inside the central ring 22, a positioning post 24 is arranged inside the central ring 22, and the positioning post 24 is threadedly connected inside the central ring 22 through the first thread groove 23, and a hollow groove 25 is opened inside the central ring 22; The connecting ring 1 is mainly used to integrate other components and play a role of connection and bearing. In the construction of subgrade slopes, it can be conveniently connected to other structures of the slope or adjacent reinforcement devices. The multi-layer telescopic sleeve 21 can adapt to different slope terrains and sizes. During the construction process, the slope gradient and width are not fixed, and the telescopic sleeve can adjust its length according to the actual slope conditions, and can accurately position the central ring 22 in a suitable position. The first thread groove 23 and the hollow groove 25 inside the central ring 22 are both key structures. The first thread groove 23 is mainly used to connect with the positioning column 24. Through the threaded connection method, the positioning column 24 can be firmly fixed inside the central ring 22, so as to achieve the precise positioning of the slope. The first thread groove 23 cooperates with the positioning column 24, and the detachable and adjustable installation of the positioning column 24 is realized through threaded connection. This connection method enables the position and depth of the positioning column 24 to be adjusted according to actual needs during the construction process to achieve the best reinforcement effect. The positioning column 24 is a component that directly contacts the slope soil body. The main function of the positioning column 24 is to firmly anchor the reinforcement device on the slope. By inserting a certain depth into the slope soil body, the friction and embedding effect of the soil on the positioning column 24 are used to fix the entire device, so as to achieve the purpose of reinforcing the slope. The hollow groove 25 can reduce the weight of the central ring 22 itself and reduce the resistance during the positioning of the positioning column 24; As Figures 6 - 8 shown, the extended positioning component 3, the extended positioning component 3 includes a second thread groove 31 opened inside the positioning column 24. A telescopic column 32 is arranged inside the positioning column 24. An inner rotating shaft 33 is rotatably connected inside the telescopic column 32. A reverse nail rod 34 is fixedly connected to the outer side of the inner rotating shaft 33. A convex rod 35 is fixedly connected to one end of the reverse nail rod 34 away from the inner rotating shaft 33. A limiting baffle 36 is fixedly connected to one end of the telescopic column 32 close to the inner rotating shaft 33; The second thread groove 31 cooperates with the telescopic column 32 for connecting and fixing the telescopic column 32, enabling the telescopic column 32 to perform telescopic adjustment inside the positioning column 24, while ensuring the stability and reliability of the connection. The telescopic column 32 serves as the main support part of the extended positioning assembly 3, and its extended length is adjustable, capable of adjusting the positioning depth according to the specific conditions of the slope, so as to better anchor in the soil body and enhance the reinforcement effect on the slope. The inner rotating shaft 33 serves as the rotation center of the reverse nail rod 34, and the inner rotating shaft 33 enables the reverse nail rod 34 to rotate inside the telescopic column 32, so as to deploy or retract the reverse nail rod 34 when needed, thereby maintaining the stability of the installation through the reverse fixing force. After the reverse nail rod 34 is deployed by rotation, it can increase the contact area and friction force with the soil body, thereby enhancing the anchoring force of the telescopic column 32 in the soil body and further improving the stability of the entire reinforcement device. The convex rod 35 serves as the end structure of the reverse nail rod 34, and when the reverse nail rod 34 extends outward, the resistance from the outside increases, thereby pushing out the reverse nail rod 34. The limit baffle 36 is fixed at one end of the telescopic column 32 close to the inner rotating shaft 33, mainly serving to limit the movement range of the reverse nail rod 34 and the inner rotating shaft 33, preventing them from rotating or shifting excessively, and ensuring the structural stability of the entire assembly and the normal functioning of its functions; As Figures 6 - 8 shown, the retraction assembly 4, the retraction assembly 4 includes a linear chute 41 opened inside the reverse nail rod 34, a first rotating sliding column 42 is movably connected to the linear chute 41, a connecting rod 43 is fixedly connected to the outside of the first rotating sliding column 42, a second rotating sliding column 44 is fixedly connected to one end of the connecting rod 43 away from the first rotating sliding column 42, an internal pull column 46 is slidably connected to the inside of the telescopic column 32, a receiving groove 45 is opened on the outside of the internal pull column 46, and the outside of the second rotating sliding column 44 is rotatably connected to the receiving groove 45; The linear sliding groove 41 provides a track for the linear movement of the first rotating sliding column 42, restricting its movement path and enabling it to slide smoothly along a predetermined direction, thereby achieving the guidance and control of the movement of subsequent components. The first rotating sliding column 42 moves within the linear sliding groove 41, connecting the guiding function of the linear sliding groove 41 with the connecting rod 43, playing a role in force transmission and motion conversion. It can transmit the motion and force in the direction of the linear sliding groove 41 to the connecting rod 43, and at the same time, it can rotate relative to itself to adapt to changes in different angles and motion requirements. The connecting rod 43, as an intermediate component connecting the first rotating sliding column 42 and the second rotating sliding column 44, transmits the motion and force of the first rotating sliding column 42 to the second rotating sliding column 44, realizing the linkage between different components and enabling the entire retraction assembly 4 to work in coordination. The second rotating sliding column 44 is connected to the connecting rod 43 and cooperates with the receiving groove 45 on the inner pull column 46 through a rotating connection on the outside, further transmitting the motion and force transmitted by the connecting rod 43 to the inner pull column 46. At the same time, it can rotate relative to itself to adapt to the movement direction and angle changes of the inner pull column 46 and avoid jamming. The inner pull column 46 slides inside the telescopic column 32, driving components such as the reverse nail rod 34 through its own movement to achieve the retraction action, and at the same time providing a path for power transmission during the entire retraction process. When the inner pull column 46 expands and contracts, it will drive the connecting rod 43 to achieve the pushing and pulling forces. The receiving groove 45 is opened on the outside of the inner pull column 46, used to accommodate and install the outer rotating connection part of the second rotating sliding column 44, providing a stable installation and motion basis for the second rotating sliding column 44, ensuring its reliable connection with the inner pull column 46 and the transmission of motion and force; As Figure 1 , Figure 2 shown in Figure 4 , a rigid connection assembly 5 is provided at the top of the connecting ring 1. The rigid connection assembly 5 includes a third threaded groove 51 opened inside the top of the connecting ring 1. A mounting cover 52 is threadedly connected to the third threaded groove 51. Both sides of the top of the mounting cover 52 are fixedly connected with vertical plates 53. An extension plate 54 is fixedly connected to the outside of one of the vertical plates 53, and a sliding rod 56 is fixedly connected to the outside of the other vertical plate 53. A slider 55 is slidably connected inside the extension plate 54. One end of the sliding rod 56 is fixedly connected to the slider 55. An octagonal block 57 is fixedly connected to the top of the mounting cover 52; The third thread groove 51 cooperates with the mounting cover 52 to threadedly connect the mounting cover 52 to the inner top of the connecting ring 1, realizing the detachable installation of the mounting cover 52, facilitating the assembly and disassembly of components. The mounting cover 52 is fixed to the top of the connecting ring 1 through the third thread groove 51, playing a role in closing and protecting the internal structure of the connecting ring 1, and at the same time providing an installation foundation for components such as the vertical plate 53. The vertical plate 53 is rotatably connected to both sides of the top of the mounting cover 52, serving as the installation foundation for the extension plate 54 and the slide rod 56, providing side support and connection points for the entire rigid connection assembly 5, enabling the assembly to form a whole. The extension plate 54 forms an extended rigid connecting rod, playing a role in limiting and supporting. The slider 55 is slidably connected to the inside of the extension plate 54. The slider 55 is connected to the slide rod 56. By sliding the slider 55 on the extension plate 54, the position of the slide rod 56 can be adjusted. The slide rod 56 is mainly used to realize the connection with the vertical plate 53. The octagonal block 57 is mainly used to facilitate the construction personnel to use tools to rotate the mounting cover 52, realizing the quick installation and disassembly of the mounting cover 52; As Figure 1 , Figure 3 shown in Figure 4 , an angle adjustment assembly 6 is provided on the outer side of the connecting ring 1. The angle adjustment assembly 6 includes a circular groove 61 opened on the outer side of the connecting ring 1. A rotating block 62 is slidably connected to the circular groove 61. An extension rope 63 is fixedly connected to the outer side of the rotating block 62. Connecting bottom blocks 64 are fixedly connected to the outer sides of two of the extension ropes 63, and connecting top blocks 65 are fixedly connected to the outer sides of the other two extension ropes 63. The top end of the connecting bottom block 64 is in contact with the bottom end of the connecting top block 65; The circular groove 61 provides a predetermined circular trajectory for the sliding of the rotating block 62, enabling the rotating block 62 to perform stable circular motion on the outer side of the connecting ring 1, playing a role in guiding and limiting, ensuring that the rotating block 62 will not shift or break away during the sliding process. The rotating block 62 is installed in the circular groove 61 and realizes the function of angle adjustment through sliding connection. The rotating block 62, as a key component for connecting the extension rope 63, transmits the tension or pressure of the extension rope 63 to the connecting ring 1, thereby realizing the adjustment of the angle of the entire device. One end of the extension rope 63 is fixed on the outer side of the rotating block 62, and the other end is respectively connected to the connecting bottom block 64 and the connecting top block 65. The extension rope 63 adjusts the relative position between the connecting bottom block 64 and the connecting top block 65 through its own tension or relaxation, thereby realizing the fine adjustment of the angle of the device. The connecting bottom block 64 is fixedly connected to the outer sides of the two extension ropes 63, and its top is in contact with the bottom of the connecting top block 65. The connecting bottom block 64, as the bottom support point of the entire angle adjustment assembly 6, acts together with the connecting top block 65 to form an adjustable support structure for supporting and fixing the entire reinforcement device. The connecting top block 65 is fixedly connected to the outer sides of the other two extension ropes 63, and its bottom is in contact with the top of the connecting bottom block 64. The connecting top block 65, as the top support point of the entire angle adjustment assembly 6, acts together with the connecting bottom block 64 to form a complete support structure for fixing and supporting the entire reinforcement device.

[0027] Working principle; As Figures 1 - 8 shown, Before construction, according to the slope topographic survey data, the connecting bottom block 64 and the connecting top block 65 are stretched along the extension rope 63 to an overlapping state and arranged in an array form in the predetermined construction area. Fixing parts such as high-strength bolts or ground anchors are used to penetrate the connecting bottom block 64, the connecting top block 65 and the foundation to complete the preliminary positioning of the device group. During this process, the length adjustment driving block 62 of the extension rope 63 slides in a circular motion in the circular groove 61. By changing the tension of the extension rope 63, the angle fine adjustment of a single device within a certain range can be realized, ensuring that the device array fits perpendicular to the slope surface or at the optimal stress angle, effectively dispersing the lateral pressure of the slope. After the pre-positioning is completed, the positioning column 24 is rotated by using a special torque wrench, and the spiral drilling of the positioning column 24 is realized through the first thread groove 23 inside the central ring 22. During the drilling process of the positioning column 24, the sleeve automatically extends step by step according to the soil hardness at different depths of the slope. When encountering a hard soil layer, the locking pin of the outer sleeve triggers and pops out, engaging with the inner sleeve clamping groove to form a rigid support structure, ensuring that the positioning column 24 penetrates into the soil in a vertical posture. The hollow groove 25 of the central ring 22 reduces the self-weight while reducing the soil resistance during the drilling of the positioning column 24. When the positioning column 24 reaches the designed depth, the telescopic column 32 is rotated in the reverse direction, and through the transmission of the second thread groove 31, it extends out from inside the positioning column 24. The inner rotating shaft 33 at the end of the telescopic column 32 adopts a ball bearing design and can achieve free rotation of °. When pushing the internal pull column 46, the outer accommodating groove 45 and the second rotating sliding column 44 form a lever transmission mechanism, converting the linear motion into a rotational force through the connecting rod 43, driving the reverse nail rod 34 to expand outward along the inner rotating shaft 33. The convex rod 35 at the end of the reverse nail rod 34 is in a barbed shape and generates a wedging effect with the surrounding soil during the expansion process. When the reverse nail rod 34 expands into an outward-expanded shape, the anchoring effect of the device is enhanced. Finally, the installation cover 52 is screwed into the third thread groove 51 at the top of the connecting ring 1. The extension plate 54 on the vertical plate 53 and the sliding rod 56 form an adjustable connection structure, and the distance can be slidably adjusted within the extension plate 54. Combining with the telescopic function of the sliding rod 56, the distance between adjacent connecting rings 1 can be adjusted. The construction personnel can quickly disassemble and assemble the installation cover 52 through the octagonal block 57.
