Description

Technical Field

[0001] The present invention relates to the technical field of highway construction, in particular to a reinforcement device for roadbed slope construction. Background Art

[0002] The side slope of the roadbed is the sloping part of the roadbed that connects the main body of the roadbed to the natural ground. Its main function is to maintain the stability of the roadbed and prevent the roadbed from deformation or collapse due to lateral pressure. It also helps to guide water flow and reduce rainwater erosion on the roadbed.

[0003] At present, when using common slope anchoring devices, the general construction area is usually determined on the slope first, simple drilling or piling is performed as the anchor foundation, and then the anchoring device is placed in the predetermined position and initially fixed with basic fixing parts such as bolts.

[0004] However, during this process, the ability to adjust the angle between the device and the slope surface is limited, making it difficult to ensure that the device array and the slope surface achieve the optimal force-bearing angle, thereby affecting the dispersion of the lateral pressure of the slope. When anchoring deep into the soil, facing the changes in soil hardness at different depths, it is unable to adapt and form a stable support. When encountering hard soil layers, problems such as deflection and uneven force are easily caused.

[0005] Therefore, in response to the above problems, a reinforcement device for roadbed slope construction is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and provide a reinforcement device for roadbed slope construction.

The interior of the telescopic column is slidably connected to an internal pull column, and an accommodating groove is opened on the outer side of the internal pull column.

[0011] The technical effect of adopting the above technical solution is: achieving precise angle adaptation between the device and the slope surface and dynamic adaptation to different soil layer hardness during the anchoring process, effectively dispersing lateral pressure and avoiding deflection of hard soil layers, and significantly improving the stability of the roadbed slope.

[0013] The technical effect of adopting the above technical solution is: through the threaded connection between the third thread groove and the mounting cover, the device can be quickly installed and fixed, which is convenient for connection with the preset fixings or structures on the roadbed slope, ensuring the overall stability and firmness of the device; at the same time, the rigid connection assembly can provide a stable support foundation for subsequent angle adjustment, anchoring and other operations, ensuring the force uniformity and reliability of the entire reinforcement device.

[0014] Preferably, both sides of the top of the mounting cover are fixedly connected with vertical plates, an outer side of one of the vertical plates is fixedly connected with an extension plate, and an outer side of the other vertical plate is fixedly connected with a sliding rod.

[0015] The technical effect of adopting the above technical solution is: through the combination of vertical plates, extension plates and sliding rods, multi-point fixation and multi-directional force can be achieved, thereby enhancing the stability of the installation cover and the entire device; the extension plates can provide additional connection points, which are convenient for connection with external support structures or adjacent devices, thereby enhancing the coordination of the overall structure, and the sliding rods provide a basis for subsequent sliding adjustments or connecting other movable parts, thereby improving the adaptability of the device.

[0016] Preferably, a slider is slidably connected to the interior of the extension plate, one end of the slide rod is fixedly connected to the slider, and the top end of the mounting cover is fixedly connected to an octagonal block.

[0017] The technical effect of adopting the above technical solution is: through the sliding connection of the slider inside the extension plate, combined with the fixed connection between the slide rod and the slider, the horizontal or vertical position adjustment of the slide rod inside the extension plate can be realized, thereby providing horizontal or vertical adjustability for the entire device to adapt to installation requirements of different widths or positions. The setting of the octagonal block facilitates rotation operation by tools or manual operation.

[0018] Preferably, the angle adjustment assembly includes a circular groove provided on the outside of the connecting ring, a rotating block is slidably connected to the circular groove, and an extension rope is fixedly connected to the outside of the rotating block.

[0019] The technical effect of adopting the above technical solution is: through the sliding connection between the circular groove and the rotating block, the angle of the device on the slope surface can be adjusted to adapt to slopes of different slopes, ensuring that the device fits tightly with the slope surface.

[0020] Preferably, outer sides of two of the extension ropes are fixedly connected to connecting bottom blocks, and outer sides of the other two extension ropes are fixedly connected to connecting top blocks.

[0021] The technical effect of adopting the above technical solution is: the connecting bottom block and the connecting top block fix the bottom and top of the device respectively, enhance the overall stability, and are connected by extension ropes to adapt to slopes of different slopes to ensure that the device fits tightly to the slope surface.

[0022] Preferably, a first thread groove is provided inside the center ring, and the positioning column is threadedly connected to the inside of the center ring through the first thread groove.

[0023] The technical effect of adopting the above technical solution is: through the threaded connection between the first thread groove and the positioning column, the positioning column can be adjusted and fixed in the center circle to adapt to the geological conditions and construction requirements of different slopes.

[0024] Preferably, the outer side of the second rotating slide is rotatably connected to the accommodating groove, and the top end of the connecting bottom block is in contact with the bottom end of the connecting top block.

[0025] The technical effect of adopting the above technical solution is: forming a stable support structure, enhancing the stability of the entire device, and preventing displacement or tilting during construction and use.

[0026] Preferably, the end of the reverse nail rod away from the inner rotating shaft is fixedly connected to a protruding rod, and the end of the interior of the telescopic column close to the inner rotating shaft is fixedly connected to a limit baffle.

[0027] The technical effect of adopting the above technical solution is: the convex rod increases the contact area and gripping force between the reverse nail rod and the soil, and the limit baffle limits the telescopic range of the telescopic column to ensure its linear movement.

[0028] Compared with the prior art, the advantages and positive effects of the present invention are:

[0029] 1. The multi-layer telescopic sleeve adopts a nested structure. Each sleeve layer cooperates with the locking pin through the limit slot. When the positioning column spirally drills, the sleeve gradually extends according to the hardness of the soil. When encountering a hard soil layer, the locking pin of the outer sleeve is triggered to pop out and engage with the inner slot. This design allows the sleeve to respond to changes in soil quality in real time, maintaining flexible follow-up in soft soil layers and forming rigid support in hard soil layers. This ensures that the positioning column always penetrates the soil in a vertical posture, reducing drilling resistance while maintaining stability, and effectively solving the deflection problem caused by uneven force in hard soil layers caused by traditional anchoring devices.

[0030] 2. The reverse nail rod drives the second rotating slide column through the pull column to generate a lever effect. Combined with the ball bearing of the inner rotating shaft, the barb-shaped protrusion is directionally deployed. The barb at the end engages with the soil through a wedging effect. This design strengthens the engagement between the soil and the device through mechanical wedging, forming an outward-expanding anchor support, significantly improving the friction and pull-out resistance between the device and the soil, and effectively solving the problem of anchor failure caused by loose soil or uneven force.

[0031] 3. Through the linkage design of the extension rope and the driving rotary block, when the extension rope is stretched, the driving rotary block slides in a 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. This design allows construction personnel to fine-tune the angle of each anchor device according to the actual curvature of the slope, so that the device array and the slope surface form the optimal force-bearing angle fit, maximize the contact area between the anchor device and the slope, and avoid local stress concentration caused by angle deviation.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] like Figures 1-6 As shown, this embodiment provides a technical solution: a reinforcement device for roadbed slope construction, comprising a connecting ring 1;

[0048] The positioning and reinforcement component 2 includes a multi-layer telescopic sleeve 21 fixedly connected to the interior of the connecting ring 1. The interior of the multi-layer telescopic sleeve 21 is fixedly connected to the center ring 22. The interior of the center ring 22 is provided with a first thread groove 23. The interior of the center ring 22 is provided with a positioning column 24. The positioning column 24 is threadedly connected to the interior of the center ring 22 through the first thread groove 23. The interior of the center ring 22 is provided with a hollow groove 25.

[0049] The connecting ring 1 is mainly used to integrate the other components and plays a role of connection and bearing. In the construction of roadbed slopes, it can be easily connected with 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 and width of the slope are not fixed. The telescopic sleeve can be telescoped and adjusted in length according to the actual slope conditions, and the center ring 22 can be accurately positioned in the appropriate position. The first thread groove 23 and the hollow groove 25 inside the center ring 22 are both key structures. The first thread groove 23 is mainly used to connect with the positioning column 24. The positioning column 24 can be firmly fixed inside the center ring 22 by means of threaded connection. In order to achieve precise positioning of the slope, the first thread groove 23 cooperates with the positioning column 24, and the positioning column 24 is detachable and adjustable through the threaded connection. This connection method allows 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. The main function of the positioning column 24 is to firmly anchor the reinforcement device on the slope. By inserting it into the slope soil to a certain depth, the friction and embedding effect of the soil on the positioning column 24 are used to fix the entire device, thereby achieving the purpose of reinforcing the slope. The hollow groove 25 can reduce the weight of the center ring 22 itself and reduce the resistance when positioning the positioning column 24;

[0050] like Figure 6-Figure 8 As shown, the extended positioning assembly 3 includes a second threaded groove 31 provided inside the positioning column 24, a telescopic column 32 is provided inside the positioning column 24, the inner portion of the telescopic column 32 is rotatably connected to an inner shaft 33, the outer side of the inner shaft 33 is fixedly connected to a reverse nail rod 34, the end of the reverse nail rod 34 away from the inner shaft 33 is fixedly connected to a protruding rod 35, and the inner end of the telescopic column 32 close to the inner shaft 33 is fixedly connected to a limit stopper 36;

[0051] The second thread groove 31 cooperates with the telescopic column 32 to connect and fix the telescopic column 32, so that the telescopic column 32 can be telescoped and adjusted inside the positioning column 24, while ensuring the stability and reliability of the connection. The telescopic column 32 serves as the main supporting part of the extended positioning component 3. Its extended length is adjustable, and the positioning depth can be adjusted according to the specific conditions of the slope, so as to better anchor it in the soil and enhance the reinforcement effect of the slope. The inner rotating shaft 33 serves as the rotation center of the reverse nail rod 34. The inner rotating shaft 33 enables the reverse nail rod 34 to rotate inside the telescopic column 32, so that the reverse nail rod 34 can be expanded or retracted when needed, so that the reverse fixed force can be used to To maintain the stability of the installation, the reverse nail rod 34 can increase the contact area and friction with the soil after being rotated and expanded, thereby enhancing the anchoring force of the telescopic column 32 in the soil and further improving the stability of the entire reinforcement device. The protruding rod 35 serves as the end structure of the reverse nail rod 34. When the reverse nail rod 34 extends outward, the resistance with the outside increases, thereby pushing the reverse nail rod 34 out. The limit baffle 36 is fixed to one end of the telescopic column 32 near the inner shaft 33, mainly to limit the movement range of the reverse nail rod 34 and the inner shaft 33, preventing them from excessive rotation or displacement, and ensuring the structural stability and normal function of the entire assembly.

[0052] like Figure 6-Figure 8 As shown, the retraction assembly 4 includes a linear slide 41 provided inside the reverse nail rod 34, a first rotating slide post 42 is movably connected to the linear slide 41, a connecting rod 43 is fixedly connected to the outer side of the first rotating slide post 42, and a second rotating slide post 44 is fixedly connected to the end of the connecting rod 43 away from the first rotating slide post 42. An internal pull column 46 is slidably connected to the interior of the telescopic column 32, and an accommodating groove 45 is provided on the outer side of the internal pull column 46. The outer side of the second rotating slide post 44 is rotatably connected to the accommodating groove 45;

[0053] The linear slide 41 provides a track for the linear motion of the first rotating slide 42, limiting its motion path so that it can slide smoothly in a predetermined direction, thereby guiding and controlling the movement of subsequent components. The first rotating slide 42 moves in the linear slide 41, connecting the guiding function of the linear slide 41 with the connecting rod 43, playing the role of force transmission and motion conversion, and can transmit the movement and force in the direction of the linear slide 41 to the connecting rod 43. At the same time, it can rotate relatively to adapt to changes in different angles and motion requirements. The connecting rod 43 serves as an intermediate component connecting the first rotating slide 42 and the second rotating slide 44, transmitting the movement and force of the first rotating slide 42 to the second rotating slide 44, realizing the linkage between different components, so that the entire retraction assembly 4 can work together, and the second rotating slide 44 is connected to the connecting rod 43 , and through the outer rotation connection and the receiving groove 45 on the inner pull column 46, the movement and force transmitted by the connecting rod 43 are further transmitted to the inner pull column 46, and at the same time it can rotate relatively to adapt to the movement direction and angle changes of the inner pull column 46 to avoid getting stuck. The inner pull column 46 slides inside the telescopic column 32, and drives the reverse nail rod 34 and other components to achieve retraction through its own movement, while providing a power transmission path for the entire retraction process. When the inner pull column 46 is extended and retracted, it drives the connecting rod 43 to achieve the pushing and pulling force. The receiving groove 45 is opened on the outer side of the inner pull column 46 for accommodating and installing the outer rotation connection part of the second rotating slide column 44, providing a stable installation and movement foundation for the second rotating slide column 44, ensuring that it can be reliably connected to the inner pull column 46 and transmit movement and force;

[0054] like Figure 1 、 Figure 2 and Figure 4 As shown, a rigid connection assembly 5 is provided at the top of the connection ring 1. The rigid connection assembly 5 includes a third threaded groove 51 provided inside the top of the connection ring 1. A mounting cover 52 is threadedly connected to the third threaded groove 51. Vertical plates 53 are fixedly connected to both sides of the top of the mounting cover 52. An extension plate 54 is fixedly connected to the outer side of one vertical plate 53. A sliding rod 56 is fixedly connected to the outer side of the other vertical plate 53. A slider 55 is slidably connected to the interior of 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.

[0055] The third thread groove 51 cooperates with the mounting cover 52 to thread the mounting cover 52 into the top inner part of the connecting ring 1, thereby realizing the detachable installation of the mounting cover 52 and facilitating the assembly and disassembly of the component. The mounting cover 52 is fixed to the top of the connecting ring 1 through the third thread groove 51, thereby playing the role of sealing and protecting the internal structure of the connecting ring 1, and at the same time providing an installation basis 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 basis for the extension plate 54 and the slide bar 56, providing side support and connection points for the entire rigid connection component 5, so that the component can form a whole. The extension plate 54 forms an extended rigid connection rod, which plays the role of limiting support. The slider 55 is slidably connected to the inside of the extension plate 54. The slider 55 is connected to the slide bar 56. The position of the slide bar 56 can be adjusted by sliding the slider 55 on the extension plate 54. The slide bar 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, thereby realizing the rapid installation and disassembly of the mounting cover 52.

[0056] like Figure 1 、 Figure 3 and Figure 4 As shown, an angle adjustment assembly 6 is provided on the outside of the connecting ring 1. The angle adjustment assembly 6 includes a circular groove 61 provided on the outside 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 outside of the rotating block 62. Two of the extension ropes 63 are fixedly connected to the outside of the connecting bottom block 64, and the other two extension ropes 63 are fixedly connected to the outside of the connecting top block 65. The top end of the connecting bottom block 64 contacts the bottom end of the connecting top block 65.

[0057] The circular groove 61 provides a predetermined circular trajectory for the sliding of the rotating block 62, so that the rotating block 62 can perform stable circular motion on the outside of the connecting ring 1, playing a guiding and limiting role, ensuring that the rotating block 62 will not deviate or detach during the sliding process. The rotating block 62 is installed in the circular groove 61, and the angle adjustment function is achieved through the sliding connection. The rotating block 62 is a key component for connecting the extension rope 63, which transmits the tension or pressure of the extension rope 63 to the connecting ring 1, thereby achieving adjustment of the angle of the entire device. One end of the extension rope 63 is fixed to the outside 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 connection between the bottom block 64 and the connecting top block 65 by its own tension or relaxation. The relative position between the top blocks 65 can realize fine adjustment of the angle of the device. The connecting bottom block 64 is fixedly connected to the outside of the two extension ropes 63, and its top end is in contact with the bottom end of the connecting top block 65. The connecting bottom block 64 serves as the bottom support point of the entire angle adjustment component 6, and works 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 outside of the other two extension ropes 63, and its bottom end is in contact with the top end of the connecting bottom block 64. The connecting top block 65 serves as the top support point of the entire angle adjustment component 6, and works together with the connecting bottom block 64 to form a complete support structure for fixing and supporting the entire reinforcement device.

[0058] Working principle;

[0059] like Figures 1-8 As shown,

[0060] Before construction, according to the slope topography 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 the form of an array in the predetermined construction area. High-strength bolts or anchors and other fixings 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 of the extension rope 63 is adjusted to drive the rotating block 62 to slide in a circle in the circular groove 61. By changing the tension of the extension rope 63, the angle of a single device can be fine-tuned within a range to ensure that the device array is aligned with the slope surface. The vertical or optimal force angle fits effectively to disperse the lateral pressure of the slope. After completing the pre-positioning, use a special torque wrench to rotate the positioning column 24, and realize the spiral drilling of the positioning column 24 through the first thread groove 23 inside the center ring 22. During the drilling process of the positioning column 24, the sleeve automatically extends step by step according to the hardness of the soil at different depths of the slope. When encountering a hard soil layer, the locking pin of the outer sleeve is triggered to pop out and engage with the slot of the inner sleeve to form a rigid support structure, ensuring that the positioning column 24 penetrates into the soil in a vertical posture, and the hollow groove of the center ring 22 While reducing its own weight, the soil resistance of the positioning column 24 during drilling is reduced. When the positioning column 24 reaches the designed depth, the telescopic column 32 rotates in the opposite direction and is extended from the inside of the positioning column 24 through the transmission of the second threaded groove 31. The inner rotating shaft 33 at the end of the telescopic column 32 adopts a ball bearing design, which can achieve free rotation. When the inner pulling column 46 is pushed, its outer receiving groove 45 and the second rotating slide column 44 form a lever transmission mechanism, which converts the linear motion into rotational force through the connecting rod 43, driving the reverse nail rod 34 outward along the inner rotating shaft 33. Unfold, the protruding rod 35 at the end of the reverse nail rod 34 is in the shape of a barb, which produces a wedge effect with the surrounding soil during the unfolding process. When the reverse nail rod 34 is unfolded into an outward-expanding shape, the anchoring effect of the device is enhanced. Finally, the installation cover 52 is screwed into the third threaded groove 51 on the top of the connecting ring 1. The extension plate 54 on the vertical plate 53 and the slide rod 56 form an adjustable connection structure, which can be slid in the extension plate 54 to adjust the distance. With the telescopic function of the slide rod 56, the spacing between adjacent connecting rings 1 can be adjusted. The construction personnel can quickly complete the disassembly and assembly of the installation cover 52 through the octagonal block 57.
