DETAILED DESCRIPTION

[0042] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The present application will be further described in detail.

[0043] In combination with Figure 1 , Figure 2 and Figure 3 , the embodiments of the present application disclose an anchor rod supporting device for slope reinforcement, which comprises an outer sleeve rod 11, an inner sleeve rod 12, a screw rod 13, a supporting piece 2 and a driving assembly 3. The outer sleeve rod 11 is provided with a drilling head 16 at the lower end. The inner sleeve rod 12 is rotationally connected with the outer sleeve rod 11 through a rotating piece. The screw rod 13 is rotationally arranged in the inner sleeve rod 12, and the upper end of the screw rod 13 extends out of the inner sleeve rod 12. The supporting piece 2 is slidingly arranged in the inner sleeve rod 12. The driving assembly 3 is rotationally arranged on the screw rod 13 and is used to drive the supporting piece 2 to insert into the soil layer. The outer sleeve rod 11 and the inner sleeve rod 12 are provided with mounting grooves 14 on the circumferential side. The mounting grooves 14 are provided with guide inclined surfaces. The driving assembly 3 is spaced apart and provided with multiple groups along the length direction of the screw rod 13. The supporting piece 2 is symmetrically provided with two groups. The circumferential side of the outer sleeve rod 11 is provided with threads 15.

[0044] In the embodiments of the present application, the outer sleeve rod 11, the inner sleeve rod 12 and the screw rod 13 are all in cylindrical shape. It should be noted that the diameter of the outer sleeve rod 11 is sufficient to place the inner sleeve rod 12, the inner sleeve rod 12 is attached to the outer sleeve rod 11, and the length of the screw rod 13 is greater than the length of the inner sleeve rod 12. It should be noted that the outer sleeve rod 11 is provided with a drilling head 16, and the drilling head 16 includes a front-end sharp drill body. In actual use, the drill body is made of high-strength alloy material, such as high-speed steel (HSS) or hard alloy (WC-Co), to improve the wear resistance and impact resistance of the drilling head 16.

[0045] In addition, the front end of the drill body gradually decreases in diameter to form a sharp conical head to reduce resistance encountered when passing through the soil layer. The outer sleeve rod 11 is provided with threads 15 on the side surface, which is used to better fix the outer sleeve rod 11 in the soil layer during the reinforcement process, preventing the outer sleeve rod 11 from slipping, falling off and other problems when subjected to external forces. The material of the outer sleeve rod 11 is preferably high-carbon steel or stainless steel to ensure that there is no obvious wear or corrosion during long-term use.

[0046] The end of the screw rod 13 extending out of the inner sleeve rod 12 is provided with a rotating handle 17, which is in a disc shape, so that the support member 2 can be driven to pass through the inner sleeve rod 12 and the outer sleeve rod 11 in turn and inserted into the soil layer, thereby increasing the fixing stability of the anchor rod. The support member 2 is symmetrically provided with two groups, which can keep the anchor rod balanced. The driving assembly 3 is provided with multiple groups at intervals, which further increases the stability of the anchor rod in the soil layer.

[0047] In specific use, the outer sleeve rod 11 is rotated to make the outer sleeve rod 11 enter the soil layer. Since the outer sleeve rod 11 is provided with threads 15 on the outer periphery, the anchor rod can be preliminarily fixed in the soil layer, achieving preliminary fixation of the anchor rod, i.e., preliminary support. Then the rotating handle 17 is rotated to make the screw rod 13 rotate, so that the driving assembly 3 moves linearly along the vertical direction of the screw rod 13, thereby compressing the support member 2. Due to the arrangement of the guide slope, the support member 2 can pass through the installation slot 14 and be inserted into the soil layer. This further strengthens the fixation of the anchor rod with the soil layer, i.e., further strengthens the stability of the support. Thus, the anchor rod is quickly fixed in the soil layer, which reduces the dependence on grouting for support compared to grouting support, thereby improving the construction efficiency.

[0048] In a specific embodiment, the inner periphery of the inner sleeve rod 12 is vertically provided with a guide groove 34, and the driving assembly 3 includes a fixed disc 31 and a rotating disc 32. The fixed disc 31 is sleeved on the outer periphery of the screw rod 13, and the outer periphery of the fixed disc 31 is fixedly arranged on the inner periphery of the inner sleeve rod 12. The rotating disc 32 is connected to the screw rod 13 through the thread 15, and the rotating disc 32 is slidably arranged in the guide groove 34 through a guide block 33. One end of the guide block 33 is fixedly connected to the periphery of the rotating disc 32, and the other end of the guide block 33 is slidably arranged in the guide groove 34.

[0049] In combination with Figure 1 , Figure 2 and Figure 3 , in a specific embodiment, the fixed disc 31 and the rotating disc 32 are disc-shaped, and it should be noted that the rotating disc 32 has a threaded hole 15 at the center, that is, the threaded hole 15 at the center of the rotating disc 32 is engaged with the threaded hole 15 of the screw rod 13, so that the screw rod 13 drives the rotating disc 32 to rotate when the screw rod 13 rotates. The inner circumferential side of the fixed disc 31 is in contact with the screw rod 13, that is, the fixed disc 31 has a rotating hole at the center, and the size of the rotating hole can meet the rotation of the screw rod 13. The outer circumferential side of the fixed disc 31 can be integrally formed with the inner sleeve rod 12 or fixedly connected by welding or bolting, and the specific embodiment of the application is not limited. The guide block 33 is square-shaped, and one end of the guide block 33 can be integrally formed with the outer circumferential side of the fixed disc 31 or fixedly connected by welding or bolting, and the specific embodiment of the application is not limited. The guide groove 34 is rectangular-shaped, and the length of the guide groove 34 can meet the requirement that the support piece 2 passes through the mounting hole and penetrates into the soil layer. The width of the guide groove 34 can meet the requirement that the guide block 33 slides.

[0050] In specific use, the screw rod 13 is rotated, so that the rotating disc 32 rotates with the screw rod 13. Due to the arrangement of the guide block 33, when the screw rod 13 rotates, the rotating disc 32 moves vertically along the axis of the screw rod 13, thereby driving the support piece 2 to compress or open. When the support piece 2 is compressed, the support piece 2 passes through the mounting groove 14 under the action of the guide inclined surface, so that the support piece 2 is inserted into the soil layer. When the support piece 2 is opened, the support piece 2 is withdrawn from the inner sleeve rod 12, so that the support piece 2 is separated from the soil layer, which is simple and convenient.

[0051] In combination with Figure 1 , Figure 2 and Figure 3 , in a specific embodiment, the support piece 2 includes a first connecting rod 21 and a second connecting rod 22. The upper end of the first connecting rod 21 is rotationally connected to the lower end of the rotating disc 32. The upper end of the second connecting rod 22 is rotationally connected to the lower end of the first connecting rod 21, and the lower end of the second connecting rod 22 is rotationally connected to the upper end of the fixed disc 31.

[0052] In a specific embodiment, the first connecting rod 21 and the second connecting rod 22 are both arranged in an oblong shape, and the supporting piece 2 comprises the first connecting rod 21 and the second connecting rod 22. The upper end of the first connecting rod 21 is rotationally connected to the lower end of the rotating disc 32; the upper end of the second connecting rod 22 is rotationally connected to the lower end of the first connecting rod 21, and the lower end of the second connecting rod 22 is rotationally connected to the upper end of the fixed disc 31. The first connecting rod 21 and the second connecting rod 22 are made of high-strength steel and are connected by high-strength hinges, which ensures that the connection is reliable and less likely to break. The supporting piece 2 is symmetrically provided with two groups, forming a structure similar to a butterfly to ensure balance during reinforcement. The lengths of the first connecting rod 21 and the second connecting rod 22 can be adjusted according to actual conditions, and a telescopic design is adopted to adapt to different reinforcement needs.

[0053] In specific use, when the rotating disc 32 rotates towards the end close to the fixed disc 31, the first connecting rod 21 and the second connecting rod 22 are rotationally connected, causing the first connecting rod 21 and the second connecting rod 22 to approach each other, i.e., the first connecting rod 21 and the second connecting rod 22 are compressed.

[0054] The implementation principle of the embodiment of the present application is that the outer sleeve rod 11 is rotated, causing the outer sleeve rod 11 to enter the soil layer. Since the outer sleeve rod 11 is provided with threads 15 on the outer circumferential side, the anchor rod can be preliminarily fixed in the soil layer, achieving preliminary fixation of the anchor rod, i.e., achieving preliminary support. Then the rotating handle 17 is rotated, causing the screw rod 13 to rotate, so that the driving assembly 3 moves linearly along the vertical direction of the screw rod 13, thereby compressing the supporting piece 2. Due to the arrangement of the guide inclined surface, the supporting piece 2 can pass through the installation slot 14 and be inserted into the soil layer. The fixation of the anchor rod and the soil layer is further strengthened, i.e., the stability of the support is further improved. Thus, the anchor rod is quickly fixed in the soil layer, and compared with support by grouting, the dependence on grouting liquid is reduced, thereby improving the construction efficiency.

[0055] The specific embodiment is merely an explanation of the present application, and is not a limitation of the present application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the present specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the Patent Law.
