Description

Technical Field

[0001] The utility model relates to a slope protection technology, in particular to a slope protection structure. Background Art

[0002] In most mountainous areas or construction sites where vegetation is damaged, protection systems are often needed to prevent sudden dangers such as rolling stones, falling rocks, avalanches, and mudslides. The most important component of the protection system is the wire mesh or wire rope mesh, which is woven with special steel wires or wire ropes with excellent strength and flexibility. During the use of the wire mesh or wire rope mesh, it is necessary to tighten the connection between the two meshes of the wire mesh or wire rope mesh. The traditional method is to tighten it with iron wire winding, or to use ordinary steel wire or wire rope to thread the knot, but such a fastening method is easy to cause the winding wire to loosen and slide during actual use, and the construction and installation are extremely slow and the installation cost is high. When the wire mesh or wire rope mesh is subjected to great impact, there are great safety hazards. At the same time, the mesh structure of the wire mesh cannot prevent objects or fluids such as mud, mortar, and small gravel that can pass through the mesh. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a slope protection structure, which includes

[0004] a ground anchor anchored in the ground; and

[0005] A guard assembly, the guard assembly is erected on the ground and fixedly connected to the ground anchor via a steel wire rope;

[0006] The guard assembly comprises

[0007] A connecting frame body, which is erected on the ground, and includes a frame body, wherein one end of the frame body away from the slope side is provided with a first connecting portion, and the other end of the frame body is correspondingly provided with a second connecting portion, wherein the first connecting portion can be inserted into the second connecting portion, and the connection between adjacent connecting frames is achieved by bolts penetrating and fixing the first connecting portion and the second connecting portion; and

[0008] The baffle is fixedly mounted on one side of the connecting frame body provided with the first connecting portion and the second connecting portion.

[0009] The utility model sets up a baffle on the periphery of the slope, through which fluids such as gravel, mud, mortar or small objects are blocked to avoid danger. The baffle is inserted into the first connecting part through the first connecting part and then fixed by bolts to achieve connection between adjacent guarding components, thereby realizing rapid assembly of the protective structure. The installation is simple and convenient. Compared with the protective net, the structure in the utility model is easier to process and has low cost.

[0010] Furthermore, the two ends of the connecting frame body away from the baffle are provided with third connecting parts;

[0011] A connecting assembly is provided between the third connecting parts of adjacent connecting frames, and the connection between the connecting assembly and the third connecting part is used to realize the connection of adjacent connecting frames away from the baffle side. The connecting assembly can adjust the spacing between adjacent connecting frames away from the baffle side.

[0012] Furthermore, the connection component includes

[0013] A movable part, which is rotatable along its own circumferential direction, and has external threads at both ends of the movable part; and

[0014] A fourth connecting part, one end of which can be plugged into the above-mentioned third connecting part, and a bolt is passed through the fourth connecting part and the third connecting part to fix the fourth connecting part and the third connecting part, and an end of the fourth connecting part away from the third connecting part is provided with a threaded hole matching the above-mentioned external thread, and the fourth connecting part is threadedly matched with the movable part.

[0015] By rotating the movable part, the fourth connecting part can be moved along the axial direction of the movable part, so that the angle between adjacent baffles can be adjusted.

[0016] Furthermore, the ground anchor includes an anchor rod, which can be anchored underground. The anchor rod includes

[0017] A stranded wire, wherein a plurality of stranded wires are provided, and the plurality of stranded wires form a rod portion of the anchor rod;

[0018] A grouting pipe, which is arranged parallel to the stranded wire; and

[0019] A pad, on the lower surface of which is provided a sleeve extending vertically downward, the sleeve wraps the upper part of the above-mentioned stranded wire and the upper part of the grouting pipe, and on the upper surface of the pad is provided an anchor plate, in which is opened an anchor hole for the above-mentioned stranded wire and the grouting pipe to pass through.

[0020] By inserting the part below the base plate of the ground anchor into the anchor hole, and then filling the anchor hole with anchor mortar through a grouting pipe, after it solidifies, the solidified mortar and the stranded wire form an anchor rod fixed to the ground. The connection strength is high and the construction is simple. The stranded wire in the mortar can effectively improve the shear resistance of the anchor rod, thereby improving the anchoring strength of the protective structure.

[0021] Furthermore, the anchor rod also includes an isolation plate, and the isolation plate is provided with isolation holes for the stranded wire and the grouting pipe to pass through.

[0022] The stranded wire and grouting pipe are equidistantly separated by isolation plates so that they are evenly distributed in the anchor hole, avoiding excessive concentration or dispersion of the stranded wire, which would lead to reduced shear resistance of the anchor rod. At the same time, by setting up several isolation plates perpendicular to the axis of the stranded wire, the tensile strength of the anchor rod can be effectively improved, thereby improving the overall anchoring effect of the ground anchor.

[0023] Furthermore, a guide cap is fixedly installed at the bottom of the stranded wire.

[0024] The guide cap guides the stranded wire to move toward the bottom of the anchor hole, so that the anchoring part of the anchor can be easily inserted into the anchor hole, thereby preventing the stranded wire from being deformed when being inserted into the anchor hole.

[0025] Furthermore, the ground anchor also includes a buffer portion above the ground, the buffer portion is fixed to the anchor plate of the anchor rod, the guard assembly is connected to the buffer portion through a steel wire rope, and the buffer portion includes

[0026] A connecting column, which is fixed to the anchor plate;

[0027] a connecting plate, the connecting plate being fixedly connected to the steel wire rope; and

[0028] The damper is arranged between the connecting column and the connecting plate, and an elastic part is arranged on the outer sleeve of the damper.

[0029] Furthermore, the connecting column is threadedly connected to the anchor plate.

[0030] After the baffle or connecting frame receives an impact, the guard assembly will pull the buffer assembly through the steel wire rope to stretch the damper and the elastic part in the buffer assembly. During the stretching process, the movement of the damper and the deformation of the elastic part will absorb part of the impact kinetic energy. At the same time, during the movement of the damper, the friction between the damping medium in the damper and the damper piston rod will also consume part of the impact kinetic energy, thereby reducing the tension on the anchor and improving the stability of the protective structure.

[0031] The utility model has the following advantages:

[0032] The utility model sets up a baffle on the periphery of the slope, through which fluids such as gravel, mud, mortar or small objects are blocked to avoid danger. The baffle is inserted into the first connecting part through the first connecting part and then fixed by bolts to achieve connection between adjacent guarding components, thereby realizing rapid assembly of the protective structure. The installation is simple and convenient. Compared with the protective net, the structure in the utility model is easier to process and has low cost.

[0033] By rotating the movable part, the fourth connecting part can be moved along the axial direction of the movable part, so that the angle between adjacent baffles can be adjusted.

[0034] By inserting the part below the base plate of the ground anchor into the anchor hole, and then filling the anchor hole with anchor mortar through a grouting pipe, after it solidifies, the solidified mortar and the stranded wire form an anchor rod fixed to the ground. The connection strength is high and the construction is simple. The stranded wire in the mortar can effectively improve the shear resistance of the anchor rod, thereby improving the anchoring strength of the protective structure.

[0035] The stranded wire and grouting pipe are equidistantly separated by isolation plates so that they are evenly distributed in the anchor hole, avoiding excessive concentration or dispersion of the stranded wire, which would lead to reduced shear resistance of the anchor rod. At the same time, by setting up several isolation plates perpendicular to the axis of the stranded wire, the tensile strength of the anchor rod can be effectively improved, thereby improving the overall anchoring effect of the ground anchor.

[0036] The guide cap guides the stranded wire to move toward the bottom of the anchor hole, so that the anchoring part of the anchor can be easily inserted into the anchor hole, thereby preventing the stranded wire from being deformed when being inserted into the anchor hole.

[0037] After the baffle or connecting frame receives an impact, the guard assembly will pull the buffer assembly through the steel wire rope to stretch the damper and the elastic part in the buffer assembly. During the stretching process, the movement of the damper and the deformation of the elastic part will absorb part of the impact kinetic energy. At the same time, during the movement of the damper, the friction between the damping medium in the damper and the damper piston rod will also consume part of the impact kinetic energy, thereby reducing the tension on the anchor and improving the stability of the protective structure.

[0050] Embodiment 1:

[0051] In order to solve the technical problems existing in the prior art, this embodiment provides a slope protection structure, such as Figure 1 As shown, the slope protection structure in this embodiment includes

[0052] a ground anchor 100 anchored underground; and

[0053] A guard assembly 200, which is erected on the ground and fixedly connected to the ground anchor 100 via a steel wire rope 300;

[0054] like Figure 2 As shown, the shielding assembly 200 includes

[0055] The connecting frame 220 is erected on the ground. Figure 4 , 5 As shown, the connecting frame 220 in this embodiment includes a frame 221, and a first connecting portion 223 is provided at one end of the frame 221 away from the slope side, and a second connecting portion 224 is correspondingly provided at the other end of the side, and the first connecting portion 223 can be inserted into the second connecting portion 224, and the connection between adjacent connecting frames 220 is achieved by fixing the first connecting portion and the second connecting portion through bolts; and

[0056] The baffle 210 is fixedly mounted on one side of the connecting frame 220 where the first connecting portion and the second connecting portion are provided.

[0057] In this embodiment, a baffle is erected on the periphery of the slope to block fluids such as gravel, mud, mortar, or small objects to avoid danger. The baffle is inserted into the first connecting part through the first connecting part 223 and then fixed by bolts to achieve connection between adjacent guarding components, thereby achieving rapid assembly of the protective structure. The installation is simple and convenient. Compared with the protective net, the structure in the utility model is easier to process and has low cost.

[0058] In this embodiment, the structures of the first connecting portion and the second connecting portion can be as follows: Figure 4 , 5 As shown, two parallel plate structures are arranged. In order to enable the first connecting part to be inserted into the second connecting part, the spacing between the upper and lower parallel plate outer surfaces of the first connecting part should be smaller than the spacing between the upper and lower parallel plate inner surfaces of the second connecting part. In addition, insertion holes can be opened on the first and second connecting parts so that bolts can be inserted into the insertion holes to fix the first and second connecting parts.

[0059] In addition, the first connecting part can be designed into a rod shape, and the second connecting part can be designed into a sleeve shape that can wrap the first connecting part, and insertion holes can be opened in the first connecting part and the second connecting part so that bolts can be inserted into the insertion holes to fix the first connecting part and the second connecting part.

[0060] Embodiment 2:

[0061] In order to adjust the angle between adjacent baffles according to actual installation requirements, this embodiment proposes optimization based on the first embodiment.

[0062] like Figure 3 As shown, the difference from the first embodiment is that the third connection parts 222 are provided at both ends of the connecting frame 220 away from the baffle 210;

[0063] A connecting assembly 230 is provided between the third connecting portions 222 of adjacent connecting frames, and the connection between the connecting assembly 230 and the third connecting portion 222 is used to realize the connection of adjacent connecting frames away from the baffle side. The connecting assembly can adjust the spacing between adjacent connecting frames away from the baffle side.

[0064] The connection component includes

[0065] A movable part 231, wherein the movable part 231 can rotate along its own circumferential direction, and both ends of the movable part 231 are provided with external threads; and

[0066] The fourth connecting part 232, one end of which can be plugged into the third connecting part 222, and bolts are passed through the fourth connecting part and the third connecting part to fix the fourth connecting part and the third connecting part. The end of the fourth connecting part 232 away from the third connecting part 222 is provided with a threaded hole matching the above-mentioned external thread, and the fourth connecting part is threadedly matched with the movable part.

[0067] By rotating the movable portion 231 , the fourth connecting portion 232 can be moved along the axis direction of the movable portion, so that the angle between adjacent baffles can be adjusted.

[0068] In order to achieve relative rotation on the side of the connecting frame where the baffle is provided, the first connecting part and the second connecting part in this embodiment can select the parallel plate structure described in Example 1, and the first connecting part and the second connecting part can be relatively rotated by loosening the bolts. At this time, rotating the movable part 231 can make the fourth connecting part 232 move along the axial direction of the movable part. In this process, the first connecting part and the second connecting part rotate relative to each other, thereby achieving adjustment of the angle between adjacent baffles.

[0069] Of course, in addition to the above-mentioned method of adjusting the angle by means of threads, other methods can also be used. For example, the third connecting part and the fourth connecting part are not connected by threads, but a socket is opened at both ends of the third connecting part, and several connecting holes arranged along the axial direction of the fourth connecting part are opened in a section of the fourth connecting part close to the third connecting part. The connecting holes at different positions correspond to the sockets, and mounting bolts are inserted to achieve angle adjustment between adjacent baffles.

[0070] Embodiment 3:

[0071] In order to improve the anchoring effect of the slope protection structure, this embodiment proposes an optimization based on the above embodiment. Different from the above embodiment, the ground anchor 100 in this embodiment includes an anchor rod 120, which can be anchored underground. Figure 6 , 7 As shown, the anchor rod 120 includes

[0072] A strand 125, wherein a plurality of strands 125 are provided, and the plurality of strands 125 form a rod portion of the anchor rod 120;

[0073] A grouting pipe 124, which is arranged parallel to the stranded wire; and

[0074] A backing plate 121 is provided on its lower surface with a sleeve 122 extending vertically downward, the sleeve 122 wraps the upper part of the above-mentioned stranded wire and the upper part of the grouting pipe, and an anchor plate 123 is provided on its upper surface, the anchor plate 123 is provided with an anchor hole for the above-mentioned stranded wire and the grouting pipe to pass through.

[0075] By inserting the part below the base plate of the ground anchor into the anchor hole, and then filling the anchor hole with anchor mortar through a grouting pipe, after it solidifies, the solidified mortar and the stranded wire form an anchor rod fixed to the ground. The connection strength is high and the construction is simple. The stranded wire in the mortar can effectively improve the shear resistance of the anchor rod, thereby improving the anchoring strength of the protective structure.

[0076] Exemplarily, the stranded wire in this embodiment may be a stranded steel wire.

[0077] like Figure 8 As shown, in this embodiment, the anchor rod 120 may further include an isolation plate 126, on which isolation holes are provided for the stranded wire and the grouting pipe to pass through.

[0078] The stranded wire and grouting pipe are equidistantly separated by isolation plates so that they are evenly distributed in the anchor hole, avoiding excessive concentration or dispersion of the stranded wire, which would lead to reduced shear resistance of the anchor rod. At the same time, by setting up several isolation plates perpendicular to the axis of the stranded wire, the tensile strength of the anchor rod can be effectively improved, thereby improving the overall anchoring effect of the ground anchor.

[0079] In this embodiment, a guide cap 127 may also be fixedly installed at the bottom of the stranded wire.

[0080] The guide cap 127 guides the stranded wire to move toward the bottom of the anchor hole, so that the anchoring part of the anchor can be easily inserted into the anchor hole, thereby preventing the stranded wire from being deformed when being inserted into the anchor hole.

[0081] Embodiment 4:

[0082] In order to reduce the pulling force on the anchor when the baffle is impacted, this embodiment proposes an improvement based on the embodiment 3. The difference from the embodiment 3 is that Fig. 9 As shown, the ground anchor in this embodiment also includes a buffer portion 110 above the ground, the buffer portion 110 is fixed to the anchor plate of the anchor rod, the guard assembly is connected to the buffer portion 110 through a steel wire rope, and the buffer portion 110 includes

[0083] A connecting column 114, wherein the connecting column 114 is fixed to the anchor plate;

[0084] A connecting plate 111, the connecting plate 111 is fixedly connected to the steel wire rope; and

[0085] The damper 112 is disposed between the connection column 114 and the connection plate 111 , and an elastic portion 113 is disposed on the outer sleeve of the damper 112 .

[0086] In this embodiment, the connection column and the anchor plate can be connected by means of threads.

[0087] After the baffle or the connecting frame receives an impact, the guard assembly will pull the buffer assembly through the steel wire rope to stretch the damper 112 and the elastic part 113 in the buffer assembly. During the stretching process, the movement of the damper and the deformation of the elastic part will absorb part of the impact kinetic energy. At the same time, during the movement of the damper, the friction between the damping medium in the damper and the damper piston rod will also consume part of the impact kinetic energy, thereby reducing the tension on the anchor and improving the stability of the protective structure.

[0088] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
