Description

Technical Field

[0001] This application relates to the technical field of slope protection, and in particular to a slope protection structure. Background Technology

[0002] Currently, with the development of the construction field and the improvement of construction technology, slope protection has become the main research object of new buildings on existing urban mountains and integrated municipal engineering projects in order to make full use of slope resources.

[0003] Slope protection refers to the measures taken to support, reinforce, and protect slopes to ensure their safety and that of their environment. Commonly used slope protection structures include: gravity retaining walls, buttress retaining walls, cantilever supports, ribbed or lattice anchored retaining walls, pile anchored retaining walls, shotcrete supports, and the slope ratio method.

[0004] Among them, lattice-type anchor retaining wall support has high adaptability to different types of slopes, so it is also suitable for multi-level slopes and has a good support effect. In the construction process of lattice-type anchor retaining wall support, several anchors are first fixed on the slope, then a steel formwork is built on the slope surface, and finally concrete is poured to form a lattice (frame) structure. After the concrete solidifies, the anchors are connected, thereby providing support for the slope.

[0005] However, in existing methods of supporting multi-level slopes with lattice-type anchor retaining walls, the lattice-type anchor retaining wall structures on adjacent slopes are also connected through lattice-type anchor retaining wall structures. Because anchor structures are difficult to fix at the edges of the slope, connecting the lattice-type anchor retaining wall structures on adjacent slopes through lattice-type anchor retaining wall structures is quite challenging. Furthermore, when geological movements occur on the slope, the stress between the lattice-type anchor retaining wall structures on adjacent slopes is significant, thus requiring high connection strength between them. Summary of the Invention

[0006] This application provides a slope protection structure that can reduce construction difficulty and improve the overall structural strength of the slope protection structure, thereby improving the slope protection effect.

[0007] This application provides a slope protection structure, which adopts the following technical solution:

[0008] A slope protection structure includes a plurality of slope protection components and a plurality of connecting devices for connecting adjacent slope protection components. Each slope protection component includes a plurality of anchor bolts. Each connecting device includes two abutment plates, a plurality of first positioning elements, and a plurality of second positioning elements. The two abutment plates are rotatably connected, and each abutment plate has a plurality of first through holes. The plurality of first positioning elements and the plurality of second positioning elements are respectively inserted into different first through holes. The structure also includes a plurality of connecting elements, each connecting element being disposed at the end of an abutment plate away from the other abutment plate, and each connecting element having a second through hole for the anchor bolts to pass through.

[0009] By adopting the above technical solution, the connecting device is installed at the junction of the slopes. Adjusting the rotation of the two abutment plates allows them to adapt to different angles on adjacent slopes, ensuring that the two abutment plates are in contact with and abut against the adjacent slopes. Then, several first positioning pieces and several second positioning pieces are passed through the two abutment plates to fix their positions to the slope. After the anchor rods pass through the connecting pieces, construction continues to form a slope support assembly. Several connecting devices are then connected through this assembly. This improves the structural strength of the slope support structure at the slope junction, thereby increasing the overall structural strength of the slope support structure and enhancing its support effect on the slope. Furthermore, the construction process of the connecting device is convenient and quick, with low construction difficulty, thus reducing the construction difficulty of multi-level slope support structures and improving construction efficiency and effectiveness.

[0010] Optionally, the connecting device includes a plurality of guide members, each of which corresponds to one of the plurality of first through holes, and the guide members are disposed on the abutment plate; the guide members have an inner cavity through which the first positioning member or the second positioning member passes, and the inner cavity communicates with the first through hole.

[0011] By adopting the above technical solution, during the process of passing the first positioning component and the second positioning component through the abutment plate, the guide component can be used to assist construction personnel in using drilling tools to drill holes in the slope through the first perforation, and can also be used to assist the first positioning component and the second positioning component in passing through the abutment plate and entering the hole, thereby reducing the construction difficulty of the connecting device and making the process of positioning the connecting device on the slope more convenient and faster.

[0012] Optionally, a plurality of the guide members are inserted into the first through hole, and the guide members are threadedly engaged with the abutment plate.

[0013] By adopting the above technical solution, during the construction of the connecting device, after the two abutment plates are positioned, the guide is rotated to allow part of the guide to penetrate the slope, thereby initially positioning the two abutment plates on the slope, reducing the probability of displacement of the abutment plates during subsequent construction, and thus ensuring the construction effect of the connecting device; moreover, the guide is inserted into the slope by screwing in, which is more labor-saving, reduces the construction difficulty of inserting the guide into the slope, and makes it easier for construction personnel to control the depth of the guide inserted into the slope.

[0014] Optionally, the guide member has a limiting portion on its periphery. When the limiting portion abuts against the abutting plate, the guide member partially penetrates the slope and partially lies on the outside of the slope surface.

[0015] By adopting the above technical solution, when the guide component is rotated and partially inserted into the slope, the limiting part can limit the depth of the guide component's insertion into the slope, so that the depth of several guide components' insertion into the slope is the same. This facilitates construction specifications and ensures that several guide components are subjected to balanced forces when the abutment plate has a displacement tendency, thereby further improving the positional stability of the connecting device on the slope.

[0016] Optionally, the first positioning member includes an abutment rod and a movable rod, the movable rod passing through the abutment rod, and both ends of the movable rod extending out of the abutment rod; one end of the second positioning member is provided with a clearance groove; after the first positioning member and the second positioning member are both inserted into the corresponding guide member, the abutment rod abuts against the second positioning member, and the movable rod is engaged in the clearance groove.

[0017] By adopting the above technical solution, when the first positioning component and the second positioning component pass through different abutment plates, the first positioning component is passed through the abutment plate first, and then the second positioning component is passed through the abutment plate, so that the movable rod is engaged in the clearance groove, thereby making the first positioning component and the second positioning component engage and cooperate, forming a connection between the two, and further improving the positional stability of the connecting device on the slope; in addition, after pouring concrete, the engagement of the first positioning component and the second positioning component can further improve the overall structural stability of the connecting device.

[0018] Optionally, the end of the movable rod has a locking block, the movable rod is threadedly engaged with the abutment rod, and the abutment rod and the locking block respectively abut against the two sides of the corresponding second positioning member.

[0019] By adopting the above technical solution, after the movable rod is inserted into the clearance groove, the movable rod is controlled to rotate relative to the abutment rod, so that the locking block moves towards the abutment rod, thereby clamping the second positioning member by the locking block and the end of the abutment rod, improving the connection strength between the first positioning member and the second positioning member, thereby further improving the positional stability of the connecting device on the slope, and thus improving the structural strength of the connecting device after construction.

[0020] Optionally, after a plurality of the first positioning members and a plurality of the second positioning members are inserted into the corresponding guide members, the same abutment plate is simultaneously pierced by both the first positioning members and the second positioning members.

[0021] By adopting the above technical solution, after the first positioning component and the second positioning component are engaged, the connection between the two has the greatest resistance to the force along the length direction of the first positioning component; the first positioning component and the second positioning component are provided on different abutment plates on the connecting device, so that the directions of the greatest resistance of the first positioning component and the second positioning component that form the engagement are different, thereby improving the overall structural strength of the connecting device and thus improving its connection effect between the two slope support components.

[0022] Optionally, the connector is slidably connected to the abutment plate, and the sliding direction of the connector is parallel to the rotation axis of the abutment plate relative to the other abutment plate.

[0023] By adopting the above technical solution, after the connection device is constructed, the connecting parts can slide and adjust their position relative to the abutment plate, which facilitates the matching of the second perforation and the anchor rod at the corresponding slope position, thereby improving the adaptability of the connection device, making it easier for the slope support structure on adjacent slopes to form a connection through the connection device, and improving the fault tolerance rate during construction, further reducing the construction difficulty of the slope support structure.

[0024] Optionally, it may also include a plurality of drive components for driving the connector to slide, the drive components including a rotating rod, the rotating rod being rotatably connected to the abutment plate, the rotation axis of the rotating rod being parallel to the sliding direction of the connector, and the rotating rod being threadedly engaged with the connector.

[0025] By adopting the above technical solution, controlling the rotation of the rotating rod can drive the connecting part to slide relative to the abutment plate, making it convenient for construction personnel to adjust the position of the connecting part; furthermore, controlling the sliding of the connecting part using the principle of the lead screw can improve the accuracy of the construction personnel in adjusting the position of the connecting part, thereby improving the construction effect.

[0026] Optionally, the driving assembly further includes a driving member, which is rotatably connected to the abutment plate, and the rotation axis of the driving member is perpendicular to the plane where the abutment plate is located; one end of the driving member is linked to the rotating rod, and the other end of the driving member is located on one side of the abutment plate.

[0027] By adopting the above technical solution, controlling the rotation of the drive component can drive the rotating rod to rotate, thereby causing the connecting component to slide relative to the abutment plate. One end of the drive component extends through the abutment plate, providing construction personnel with more space to adjust the position of the connecting component. This allows construction personnel to adjust the position of the connecting component after several connecting devices have been initially positioned on the slope.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. It can reduce the construction difficulty of slope support structures on multi-level slopes, while improving the overall structural strength of the slope support structure, thereby improving the support effect on multi-level slopes.

[0030] 2. It can improve the structural strength of the slope support structure on multi-level slopes at the adjacent slope positions, reduce the probability of damage to the slope support structure at the slope interface due to geological movement, and thus ensure the support effect of the slope support structure on multi-level slopes.

[0031] 3. While reducing the construction difficulty of slope support structure, it makes the process of connecting slope support components on adjacent slopes more convenient. The connection device has high adaptability to different slope support components and can increase the fault tolerance rate during construction.

[0032] 4. It can enhance the connection strength between the connecting device and the slope after construction on the slope, thereby improving the reliability and stability of the connection effect between the connecting device and the two slope support components. Attached Figure Description

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0042] Reference Figure 1 and Figure 2 This application discloses a slope support structure for supporting multi-level slopes. In this embodiment, for ease of explanation, a multi-level slope with alternating inclined surfaces of the same inclination angle and horizontal surfaces is used as an example. In other embodiments, i.e., when the slope surfaces of the multi-level slope are inclined surfaces with different inclination angles, the technical solution provided in this application can also be applied.

[0043] The slope support structure includes several slope support components 1 and several connecting devices 2. The slope support components 1 are constructed on the slope surface, and the several connecting devices 2 are constructed at the junction of adjacent slope surfaces. The slope support components 1 on adjacent slope surfaces are connected by several connecting devices 2, so that the slope support structure can provide overall support for multi-level slopes.

[0044] The slope support component 1 includes several anchor rods 11 and a steel formwork 12. The anchor rods 11 are inserted into the slope in a direction perpendicular to the slope and fixed on the slope. The anchor rods 11 are distributed in a rectangular array on the same slope. After the anchor rods 11 are installed, the steel formwork 12 is erected on the slope. The steel formwork 12 forms a space for pouring concrete 10. After the concrete 10 is poured, the steel formwork 12 and the anchor rods 11 are embedded in the concrete 10. After the concrete 10 solidifies, the slope support component 1 forms a grid-like concrete 10 structure on the slope. Since the slope support component 1 (i.e., the grid-type anchor rod 11 retaining wall support) is a common slope support structure in this field, it will not be described in detail here, and only a brief representation is given in the accompanying drawings.

[0045] In this embodiment, during the construction of the slope support structure, several anchor rods 11 are fixedly installed on several slope surfaces, and several connecting devices 2 are installed at the junctions of several adjacent slope surfaces. After the two ends of the connecting devices 2 are fixedly connected to different slope support components 1, a steel formwork 12 is erected. After the concrete 10 is poured, several anchor rods 11, several connecting devices 2, and the steel formwork 12 are all embedded in the concrete 10. After the concrete 10 solidifies, it strengthens the connection between the slope support components 1 and several connecting devices 2. Finally, after the slope support structure is completed, the concrete 10 structure on the slope surface is in a stepped and grid-like shape.

[0046] Reference Figure 2 and Figure 3 The connecting device 2 includes two abutment plates 3, a number of first positioning elements 4, and a number of second positioning elements 5. The abutment plate 3 is a rectangular plate structure in general. The long side of the abutment plate 3 is hinged to the long side of the other abutment plate 3 to form a rotatable connection, that is, the rotation axis of the abutment plate 3 relative to the other abutment plate 3 is parallel to the length direction of any abutment plate 3.

[0047] Reference Figure 3 and Figure 4 In this embodiment, it is preferable that the angle at which the abutting plate 3 can rotate relative to the other abutting plate 3 is equal to 180°, so that the two abutting plates 3 can be rotated and adjusted so that they can fit and abut against the corresponding slope.

[0048] Reference Figure 2 and Figure 5 A plurality of first through holes 31 are provided at the center position along the width direction of the abutment plate 3. The first through holes 31 are provided on the abutment plate 3 in a direction perpendicular to the plane on which the abutment plate 3 is located. The plurality of first through holes 31 on the same abutment plate 3 are distributed at equal intervals along the length direction of the abutment plate 3.

[0049] Preferably, both the first positioning member 4 and the second positioning member 5 are cylindrical structures, and the outer diameter of the first positioning member 4 is equal to that of the second positioning member 5. Correspondingly, the first through hole 31 is preferably a circular hole, and the radial dimension of the first through hole 31 is larger than the outer diameter of the first positioning member 4, so that the first positioning member 4 and the second positioning member 5 can pass through the first through hole 31.

[0050] Reference Figure 6 and Figure 7The connecting device 2 also includes several connecting members 6. The connecting members 6 are located on the side of the abutment plate 3 away from the other abutment plate 3. The connecting members 6 have a second through hole 61 through which the anchor rod 11 passes. The opening direction of the second through hole 61 is parallel to the opening direction of the first through hole 31 on the adjacent abutment plate 3. In this embodiment, it is preferable that the second through hole 61 is also a round hole, and the radial dimension of the second through hole 61 is equal to the radial dimension of the straight hole drilled in the slope for the anchor rod 11 to pass through. For ease of illustration, in this embodiment, it is preferable that one connecting member 6 is installed on each abutment plate 3.

[0051] Furthermore, preferably, the connector 6 is slidably connected to the corresponding abutment plate 3, and the sliding direction of the connector 6 is parallel to the length direction of the abutment plate 3. Also, when the abutment plate 3 is in contact with the slope surface, the corresponding connector 6 is also in contact with the corresponding slope surface. And when the anchor rod 11 passes through the second perforation 61 and is fixed on the slope, the anchor rod 11 will apply a force to the connector 6, causing the connector 6 to press firmly against the slope surface, thereby fixing the connector 6 in position on the slope surface.

[0052] During the construction of the connecting device 2, firstly, the two abutment plates 3 are rotated to make them abut against the two adjacent slope surfaces. Then, a drilling tool is used to drill straight holes in the slope through several first perforations 31 for the first positioning piece 4 and the second positioning piece 5 to pass through. Next, several first positioning pieces 4 and several second positioning pieces 5 are passed through the first perforations 31 into the corresponding straight holes, so that the abutment plate 3 is initially positioned on the slope. Then, the connecting piece 6 is controlled to slide to determine a point on the slope for the anchor rod 11 to pass through. Then, based on several second perforations 61 on several connecting devices 2, a row of points for the anchor rod 11 to pass through is determined on the slope. Finally, the distribution of several points on the slope for the anchor rod 11 to pass through is determined. By controlling the sliding of the connecting piece 6 relative to the abutment plate 3, it is convenient for construction personnel to select a suitable location for drilling straight holes within a certain range at the junction of adjacent slope surfaces. This allows construction personnel to avoid locations that are difficult to drill or where the drilling quality is difficult to guarantee due to geological conditions, thereby improving the error tolerance rate during the construction of the slope support structure and reducing the construction difficulty.

[0053] Furthermore, preferably, a drive assembly 7 is installed on the abutment plate 3 to facilitate the control of the sliding of the connecting piece 6 by the construction personnel. Each abutment plate 3 is equipped with one drive assembly 7, which includes a rotating rod 71 and a drive component 72. The rotating rod 71 is a cylindrical structure with threads on its surface. The rotating rod 71 passes through the connecting piece 6 and is threadedly engaged with the connecting piece 6. Both ends of the rotating rod 71 are rotatably connected to the abutment plate 3, and the rotation axis of the rotating rod 71 is parallel to the sliding direction of the connecting piece 6. One end of the drive component 72 is rotatably connected to the abutment plate 3, and its rotation axis is perpendicular to the plane of the corresponding abutment plate 3. It penetrates into the interior of the abutment plate 3 and is linked with one end of the rotating rod 71 through bevel gear meshing. The other end of the drive component 72 is located on one side of the abutment plate 3 to facilitate the control of its rotation by the construction personnel. Controlling the rotation of the drive component 72 will drive the rotating rod 71 to rotate, and ultimately drive the connecting piece 6 to slide relative to the abutment plate 3.

[0054] Reference Figure 3 and Figure 5 Furthermore, the connecting device 2 also includes several guide members 8, which correspond one-to-one with several first through holes 31 on the two abutment plates 3. The guide member 8 is generally cylindrical in shape, with an internal cavity inside. Part of the guide member 8 passes through the corresponding first through hole 31, and the inner diameter of the guide member 8 is adapted to the outer diameter of the first positioning member 4 and the outer diameter of the second positioning member 5.

[0055] After the two abutment plates 3 are positioned at the junction of adjacent slopes, the inner cavity of the guide member 8 can assist construction personnel in using drilling tools to drill straight holes on the slope for the first positioning member 4 and the second positioning member 5 to pass through, so that the opening direction of the straight holes is perpendicular to the slope. At the same time, after the straight holes are drilled, during the process of the first positioning member 4 and the second positioning member 5 being inserted into the corresponding straight holes, the inner cavity of the guide member 8 can guide the first positioning member 4 and the second positioning member 5, making it easier for the first positioning member 4 and the second positioning member 5 to be inserted and installed.

[0056] When the included angle between the two slopes corresponding to the two abutting plates 3 is between 90° and 180°, the several straight holes drilled on the slope with the assistance of several guide members 8 are independent of each other; when the included angle between the two slopes corresponding to the two abutting plates 3 is between 180° and 270°, the bottoms of the two corresponding straight holes drilled on the slope with the assistance of several guide members 8 are interconnected.

[0057] Furthermore, the guide member 8 is threadedly engaged with the abutment plate 3, and one end of the guide member 8 has a pointed structure 82 that facilitates insertion into the slope. After the two abutment plates 3 are positioned at the junction of adjacent slope surfaces, the guide member 8 is controlled to rotate relative to the abutment plate 3, so that the pointed structure 82 of the guide member 8 penetrates into the slope until the guide member 8 is partially inside and partially outside the slope. At this time, several guide members 8 will fix the positions of the two abutment plates 3 on the corresponding slope surfaces. At the same time, the guide member 8 can loosen the soil on the slope surface during the process of penetrating the slope, which facilitates the subsequent drilling of straight holes for the first positioning member 4 and the second positioning member 5 to pass through.

[0058] Furthermore, the outer side of the guide member 8 has a limiting part 83, which is a circular ring structure. When the guide member 8 is rotated relative to the abutment plate 3 until the limiting part 83 abuts against the abutment plate 3, the limiting part 83 restricts the guide member 8 from continuing to rotate in the original direction. At this time, half of the guide member 8 is inserted into the slope. This makes the process of controlling the rotation of several guide members 8 more standardized for construction personnel. The portion of several guide members 8 inserted into the slope is equal, that is, the force on several guide members 8 is balanced, which can improve the effect of the guide members 8 in fixing the position of the abutment plate 3.

[0059] Furthermore, the first positioning component 4 includes an abutment rod 41 and a movable rod 42. The abutment rod 41 is generally cylindrical, and the movable rod 42 is generally cylindrical. The abutment rod 41 is fitted through the inner cavity of the guide component 8, and the abutment rod 41 can slide relative to the guide component 8 in a direction perpendicular to the corresponding abutment plate 3. After the abutment rod 41 is fitted through the guide component 8, its rotation about its own axis is restricted. The movable rod 42 is fitted through the abutment rod 41 and threaded. The axis of the movable rod 42 coincides with the axis of the abutment rod 41, and the length of the movable rod 42 is greater than the length of the abutment rod 41.

[0060] The second positioning member 5 also passes through and engages with the inner cavity of the guide member 8. The second positioning member 5 can slide relative to the guide member 8 in a direction perpendicular to the corresponding abutment plate 3, and the rotation of the second positioning member 5 about its own axis is restricted after it passes through and engages with the guide member 8. A relief groove 51 is provided at one end of the second positioning member 5, which passes through both sides of the second positioning member 5 in the same radial direction and through one end of the second positioning member 5 in the length direction.

[0061] When the angle between the two slopes corresponding to the two abutting plates 3 is between 90° and 180°, first install the first positioning piece 4, insert one end of the abutting rod 41 into the slope; then insert the end of the corresponding second positioning piece 5 away from the relief groove 51 into the slope, so that the relief groove 51 is located on the side of the corresponding abutting plate away from the slope; then insert the movable rod 42 into the abutting rod 41 and thread it into it. At this time, the movable rod 42 passes through the relief groove 51 at the same time, so that the first positioning piece 4 and the corresponding second positioning piece 5 form a snap-fit ​​engagement.

[0062] When the angle between the two slopes corresponding to the two abutting plates 3 is between 180° and 270°, the first positioning piece 4 is installed first, and the movable rod 42 is inserted into the abutting rod 41 and threaded together, so that both ends of the movable rod 42 protrude from the abutting rod 41; then one end of the abutting rod 41 is inserted into the slope, and the movable rod 42 is inserted into the slope along with the abutting rod 41; then the end of the corresponding second positioning piece 5 near the relief groove 51 is inserted into the slope, so that the end of the movable rod 42 located in the slope is engaged in the relief groove 51, so that the first positioning piece 4 and the corresponding second positioning piece 5 form a snap-fit ​​engagement.

[0063] Reference Figure 5 Furthermore, preferably, one end of the movable rod 42 has a locking block 421, and one end of the abutting rod 41 has a locking part 411. The locking block 421 has a chamfer at the end near the other end of the movable rod 42, and the locking part 411 also has the same chamfer, and both the locking block 421 and the locking part 411 can be partially engaged in the relief groove 51.

[0064] When the movable rod 42 passes through the clearance groove 51 and the locking block 421 and the locking part 411 are respectively located on both sides of the second positioning member 5 near the clearance groove 51, the movable rod 42 is controlled to rotate relative to the abutment rod 41, causing the movable rod 42 to move towards the second positioning member 5 until the locking block 421 partially enters the clearance groove 51 and abuts against the second positioning member 5. At this time, if the movable rod 42 is controlled to rotate in the original direction, the abutment rod 41 can be moved towards the second positioning member 5 relative to the second positioning member 5, causing the locking part 411 to partially enter the clearance groove 51 and abut against the second positioning member 5. At this time, the locking block 421 and the locking part 411 clamp and position the second positioning member 5, so that a fixed connection is formed between the first positioning member 4 and the second positioning member 5.

[0065] Furthermore, both the movable rod 42 and the second positioning component 5 have grouting holes 9 for pouring concrete 10. After the first positioning component 4 and the second positioning component 5 are installed, construction personnel can inject concrete 10 into the remaining space of the straight hole through one end of the grouting hole 9, thereby forming a fixed connection between the first positioning component 4 and the second positioning component 5 and the slope through the solidified concrete 10. Moreover, the step of pouring concrete 10 through the grouting hole 9 must precede the overall pouring of concrete 10 for the slope support structure.

[0066] Reference Figure 2 and Figure 3 Furthermore, at least two first through holes 31 are provided on the same abutting plate 3. In this embodiment, it is preferable that two first through holes 31 are provided on each abutting plate 3, and preferably two first positioning members 4 or two second positioning members 5 are allowed to pass through the same abutting plate 3.

[0067] The connecting device 2 has multiple sets of first positioning elements 4 and second positioning elements 5, and the first positioning elements 4 and the corresponding second positioning elements 5 can form a fixed connection, thereby improving the overall structural strength of the connecting device 2.

[0068] Furthermore, in this embodiment, it is preferable that at least one first positioning member 4 and at least one second positioning member 5 pass through each abutting plate 3, that is, one first positioning member 4 and one second positioning member 5 pass through the same abutting plate 3 respectively (not shown in the figure).

[0069] Since the first positioning member 4 and the second positioning member 5 are fixedly connected, the connection position of the two has the strongest resistance to the force along the length direction of the first positioning member 4; on the same connecting device 2, the two sets of first positioning members 4 and second positioning members 5 have different directions of the strongest resistance at their connection positions, which can improve the overall structural strength of the connecting device 2.

[0070] The implementation principle of a slope protection structure according to an embodiment of this application is as follows:

[0071] During the construction of the slope protection structure, several connecting devices 2 connect the slope protection components 1 on adjacent slopes. The connecting devices 2 themselves are fixed in position on the slope through several guides 8, several first positioning parts 4 and second positioning parts 5, and the corresponding first positioning parts 4 and second positioning parts 5 are fixedly connected. This can further improve the structural strength of the connecting devices 2 and its positional stability on the slope, thereby improving the overall structural strength of the slope protection structure and thus improving the support effect of the slope protection structure on multi-level slopes.

[0072] The position of the connector 6 can be adjusted by the drive component 7, thereby reducing the difficulty of constructing the slope support component 1 on the slope and improving the fault tolerance rate.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
