Description

Technical Field

[0001] The present application relates to the field of road engineering construction, and in particular to a high-stability slope support structure. Background Art

[0002] Slope support structures are important structures used in civil engineering to stabilize slopes and side slopes. They are commonly found on mountain highways and on the slopes along the sides of highways. They are primarily used to prevent soil erosion, landslides, and collapses, ensuring project safety and the stability of the surrounding environment. Slope support structures must be constructed before road construction to ensure the stability of the roadbed, pavement, and surrounding mountains during construction.

[0003] Generally speaking, the common slope support structure is steel rods. Holes are drilled in advance on the inclined mountain surface or slope surface to be supported, and then the steel rods are inserted into the pre-drilled holes. Metal rods are then tied along the soil surface at the part of the steel rods protruding from the soil. That is, a layer of metal rod mesh is laid on the soil surface to stabilize the soil surface and prevent collapse. Finally, concrete slurry is injected into the drilled holes to stabilize the interior of the soil, thereby achieving full reinforcement of the soil.

[0004] Existing slope structures have some shortcomings, primarily due to the lack of adjustment mechanisms on the traditional steel rod bodies. Adjusting the metal rod connection position relies solely on adjusting the lashing points. Therefore, improvements could be made to the steel rod body to facilitate connection and adjustment of the connection position. Summary of the Invention

[0005] In order to improve the installation efficiency of the slope support device and simplify the installation method of the slope support structure, the present application provides a high-stability slope support structure.

[0006] The high-stability slope support structure provided in this application adopts the following technical solutions:

[0007] A high-stability slope support structure comprises a steel rod, one end of which is fixedly connected to a plurality of first lugs, the plurality of first lugs being symmetrically distributed along the central axis of the steel rod at both ends of a diameter of the steel rod, the first lugs being distributed at equal intervals along the axial direction of the steel rod, and the first lugs being provided with insertion holes;

[0008] A steel plate, wherein a main hole adapted to the steel rod and the first ear plate is opened in the center of the plate surface, and the steel rod is inserted into the main hole to connect the steel plate to the steel rod;

[0009] The limiting structure is arranged between the steel rod and two adjacent first ear plates, and is used to fix the position of the steel plate on the steel rod.

[0010] By adopting the above technical solution, construction workers insert steel rods into the drill hole. If the drill hole is deep, multiple steel rods need to be coaxially connected, so that the bottom steel rod abuts the bottom of the drill hole, and the top steel rod extends out of the soil. The part extending out of the soil is connected to the steel plate. The plate surface abuts the soil or there is a narrow gap between it and the soil surface, so that the surface of the steel plate effectively prevents the soil from collapsing.

[0011] After the steel disc is installed, the limiting mechanism is used to clamp the steel disc at a predetermined position.

[0012] Optionally, a connecting ring is provided at one end of the steel rod, the inner diameter of the connecting ring is equal to the outer diameter of the steel rod, and one end of the steel rod is sleeved on the connecting ring to connect multiple steel rods.

[0013] By adopting the above technical solution, a connecting ring is provided on the steel ring. When the steel ring is connected and plugged into the end of another steel ring, the inner diameter of the connecting ring on the steel ring is used to plug into one end of the steel ring to complete a stable connection.

[0014] Optionally, the limiting structure includes:

[0015] A second base plate, one end of which is fixed to the steel rod body and is parallel to the first ear plate, wherein the height and width of the second base plate are smaller than those of the first ear plate;

[0016] The second ear plate is rotatably connected to the top of the second base plate, and the plate surface is perpendicular to the axial direction of the steel rod.

[0017] By adopting the above technical solution, after the above steel disc is fixed on the steel rod, the second ear plate rotates on the second ear plate. During the rotation process, the second ear plate always remains perpendicular to the axial direction of the steel rod, rotates to be parallel to the surface of the steel disc, abuts against the surface of the steel disc, and remains stable under the action of the surface of the steel disc and no longer rotates, thereby enhancing the fixing effect of the surface of the steel disc;

[0018] The second base plate provides stable support for the rotation of the second ear plate.

[0019] Optionally, or alternatively, the limiting structure includes:

[0020] The steel plate is provided with a through hole perpendicular to the axial direction of the plate surface, and the through hole passes through the steel plate body;

[0021] The through-holes are provided through the portions of the steel plate corresponding to the plug-in holes on the two first ear plates, and the through-holes are used for plugging in metal rods.

[0022] By adopting the above technical solution, the stable support of the steel plate is achieved in another way. A metal rod is inserted into the steel plate body. The metal rod passes through the internal perforation of the steel plate body and the plug hole on the first ear plate at the same time. The steel plate is stabilized while the metal rod is installed. The metal rod is arranged with the help of the perforated structure inside the steel plate body.

[0023] This solution is usually chosen in practical applications.

[0024] Optionally, a first base plate is provided between each of the first ear plates and the steel rod body, and the first ear plate is rotatably connected to the first base plate.

[0025] By adopting the above technical solution, the above-mentioned first ear plate is set to be rotatable. When the slope to be fixed is a curved slope in the horizontal direction, the first ear plate is rotated to a reasonable angle so that a certain angle is formed between the metal rods to adapt to the curvature between the soil slope surfaces.

[0026] Optionally, the width of an edge on the same side of the second ear plate and the second base plate is smaller than the width of an edge on the other side.

[0027] By adopting the above technical solution, one side of the second ear plate and the second base plate, that is, the side inclined downward after the steel rod is inserted into the drilled hole, is the blade side. When the steel rod is inserted into the drilled hole, the resistance of the soil to the second ear plate and the second base plate during the insertion process is reduced.

[0028] Optionally, the main hole diameter is larger than the outer diameter of the rod body.

[0029] By adopting the above technical solution, the diameter of the main hole is larger than the outer diameter of the rod body, which can accommodate the flexible rotation of the rod body and adapt to the angle adjustment of the rod body at a reasonable angle.

[0030] Optionally, an extension groove adapted to the shape of the steel plate corner is opened at the corner of the side wall of the steel plate, and the extension groove is opened parallel to the steel plate;

[0031] An extension hole is provided at the corner portion of the steel plate perpendicular to the plate surface, and the extension hole is connected to the extension groove.

[0032] By adopting the above technical solution, the extension groove is opened at the corner of the steel plate. After the steel plate is installed on the soil surface or above the soil, the corresponding part of the other steel plate is installed in the extension groove of the steel plate to achieve the extension of the steel plate surface and fix the soil around the steel rod body.

[0033] Accordingly, the steel plate as the extension portion needs to be provided with a structure for adapting to the extension groove and the extension hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following is combined with Figure 1-7 This application is described in further detail.

[0043] The embodiment of the present application discloses a high stability slope support structure. Figure 1 A high-stability slope support structure includes a steel rod 1 and a steel plate 2. The interior of the steel rod 1 is evacuated into a circular tube. After the steel rod 1 is inserted into the drilled hole, concrete slurry can be injected into the steel rod 1 to fill the drilled hole. The steel plate 2 can be installed on the steel rod 1. After the steel rod 1 is inserted into the drilled hole opened on the soil, the remaining part is exposed outside the drilled hole, and the steel plate 2 is installed to the part of the soil exposed to the outside.

[0044] Reference Figure 1 and Figure 2 A connecting ring 11 is formed at one end of the rod body of the steel rod 1. The part where the connecting ring 11 is connected to the rod body of the steel rod 1 is arranged in a stepped shape. A connecting groove is opened inside the connecting ring 11. The shape and size of the connecting groove are adapted to the rod body of the steel rod 1, so that the other end of the rod body of the steel rod 1 is inserted into the connecting groove to complete the connection between the steel rods 1.

[0045] Reference Figure 1The body of the steel rod 1 is formed with a structure for fixing the steel disc 2 and adjusting the installation position of the steel disc 2. The structure mainly includes a first base plate 12 formed on the body of the steel rod 1. The surface of the first base plate 12 is perpendicular to the axial direction of the steel rod 1. The first base plates 12 are distributed at both ends of a diameter of the steel rod 1, and multiple first base plates 12 on the same side are evenly spaced along the axial direction of the steel rod 1. Each first base plate 12 is provided with a first ear plate 13 of equal width and length. The surface of the first ear plate 13 is perforated with a plug-in hole 131. The plug-in hole 131 is used to plug in a metal rod, thereby building a support net. The steel disc 2 is in the shape of a rectangular plate. The center part of its disc surface is perforated with a main hole 21. The aperture of the main hole 21 is not less than the aperture of the steel rod 1, so that the body part of the steel rod 1 can be completely plugged into the main hole 21. Corresponding through-holes 22 are provided on the parts of the main hole 21 corresponding to the two first ear plates 13, so that the first ear plate 13 can be smoothly plugged into the main hole 21. Thus, the connection between the portion of the steel rod 1 protruding from the drilled hole in the soil and the steel plate 2 is completed by plugging the main hole 21 into the main body of the steel rod 1 and the first ear plate 13 .

[0046] Reference Figure 3 and Figure 4 The inside of the steel plate 2 is provided with a through hole 22 in a direction parallel to the surface of the steel plate 2. The aperture of the through hole 22 is the same as the aperture of the plug-in hole 131 on the first ear plate 13. The through hole 22 is provided in the part of the main hole 21 on the steel plate 2 corresponding to the first ear plate 13. When the steel plate 2 is installed on the steel rod 1, the through hole 22 on the steel plate 2 is aligned with the plug-in hole 131, and the metal rod is plugged into the steel plate 2 and the steel rod 1 at the same time, which not only completes the fixation of the steel plate 2, but also completes the plug-in distribution of the metal rod.

[0047] Reference Figure 3 , the two opposite corner parts of the steel plate 2 are also provided with extension grooves 23, which are rectangular grooves and are opened parallel to the surface of the steel plate 2. The other two opposite corner parts of the steel plate 2 are formed with extension parts that adapt to the extension grooves 23. The steel plate 2 is in the diameter of the extension part. The extension part of one steel plate 2 is plugged into the extension groove 23 to realize the plug-in connection between the steel plates 2 and the steel plates 2. In order to fix the other steel plate 2 connected through the extension groove 23, the groove wall of the extension groove 23 and the corresponding position of the extension part of the steel plate 2 are penetrated by extension holes 24. The axial direction of the extension hole 24 is perpendicular to the disk surface of the steel plate 2, and the steel plate 2 is penetrated at the same time by inserting the metal rod.

[0048] Reference Figure 4 and Figure 5 The first ear plate 13 rotates to change the horizontal distribution angle of the metal rod. In order to accommodate the horizontal rotation of the metal rod, the aperture of the main hole 21 should be larger than the diameter of the steel rod 1. The steel plate 2 is fixed by fitting and clamping the main hole 21 and the first ear plate 13.

[0049] Reference Figure 6 and Figure 7In addition, this embodiment also introduces a method for fixing the steel plate 2, that is, a second base plate 14 is formed on the rod body of the steel rod 1, and the second base plate 14 corresponds to each first base plate 12 one by one, and is arranged on the side of each first base plate 12 close to the connecting ring 11, and the first base plate 12 and the second base plate 14 on the same side of the steel rod 1 are distributed in a straight line; a second ear plate 15 is rotatably connected to the second base plate 14, and after the steel plate 2 is fixed, the second ear plate 15 is rotated so that the plate surface of the second ear plate 15 is parallel to and abuts against the plate surface of the steel plate 2, thereby supporting the steel plate 2. This method is suitable for the situation where the through hole 22 on the plate body of the steel plate 2 is not aligned with the plug hole 131 on the first ear plate 13, and the steel plate 2 is fixed by relying on the metal rod body and the second ear plate 15 inserted in the plug hole 131.

[0050] In this embodiment, the rotation of the first ear plate 13 and the second ear plate 15 is achieved by relying on a rotating shaft, that is, a rotating pin is formed in the middle part of the bottom side of the first ear plate 13 and the second ear plate 15, and the rotating pin is inserted into the first base plate 12 and the second base plate 14. The rotation can be achieved by the construction personnel twisting the rotating pin.

[0051] Reference Figure 6 and Figure 7 When the second base plate 14 and the second ear plate 15 are added, the edge size of one side close to the rotating ring before the second base plate 14 rotates is smaller than the other side, so that the edge of this side is a sharp edge side. When the rod body of the steel rod 1 is inserted into the drill hole, the resistance of the drill hole wall in the soil to the steel rod 1 is reduced.

[0052] The implementation principle of a high-stability slope support structure in an embodiment of the present application is as follows: construction workers drill holes on the soil slope to be supported in advance, and then insert a steel rod 1, or multiple steel rods 1 into a drilled hole in sequence. If multiple steel rods 1 are inserted in sequence, the steel rods 1 are connected to each other through a connecting ring 11, and the steel plate 2 is inserted into the part of the soil where the steel rod 1 extends.

[0053] The construction personnel calculate the placement position of the steel plate 2. If the location of the plug hole 131 of the first ear plate 13 is within a reasonable position, the technical solution of aligning the through hole 22 of the steel plate 2 with the plug hole 131 is preferred, and the metal rod is inserted.

[0054] If the position of the plug-in hole 131 of the first ear plate 13 cannot be too high, the construction personnel will place the steel plate 2 on the second ear plate 15, rotate the second ear plate 15 so that the second ear plate 15 fits the steel plate 2 to play a supporting role, and then insert the metal rod into the plug-in hole 131 of the first ear plate 13, and fix the steel plate 2 by limiting the parallelism of the metal rod and the second ear plate 15.

[0055] If the soil slope is curved, the metal rod needs to change its angle in the horizontal plane. The first base plate 12 is rotated appropriately. Of course, the second base plate 14 also needs to be rotated accordingly, thereby driving the metal rod to change in the horizontal plane and tie it with the end of another metal rod to complete the construction of the support net.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
