[0025] Please see Figs. 1-3This utility model provides a slope support structure, including: a retaining structure 1 laid on the slope, wherein the retaining structure 1 is fixed on the slope by a plurality of evenly distributed anchor rods 2.

[0026] The anchor rod 2 includes an anchor tube 3 and a drive rod 5. The drive rod 5 is coaxially spaced inside the anchor tube 3. Multiple windows 11 are evenly opened along the axial and circumferential directions on the tube body of the anchor tube 3. An anchoring unit is provided between each window 11 and the rod body of the drive rod 5. The drive rod 5 can control the anchoring unit to perform multi-level anchoring at different depths in the slope.

[0027] A casting channel is formed between the anchor pipe 3 and the drive rod 5 for casting and fixing the anchoring unit;

[0028] The bottom of the anchor pipe 3 is provided with a guide head 6; the top of the anchor pipe 3 is provided with a swaying component, which is used to drive the drive rod 5 to sway up and down, and drive the anchoring unit to push the slurry to make it fill more densely.

[0029] Specifically, the support structure 1 is a support plate or a support mesh.

[0030] It should be explained that when the anchor rod 2 is used to fix the retaining structure 1, several installation holes are pre-drilled on the vertical slope surface of the slope using a drilling device. Multiple enlarged hole sections are opened in the installation holes in the axial direction corresponding to the anchoring unit.

[0031] In use, the anchor rod 2 is placed in the installation hole, and the driving rod 5 drives each anchoring unit to anchor in the corresponding enlarged hole section, achieving multi-stage anchoring of the anchor rod 2. Then, the pouring device is used to pour the slurry through the pouring channel and window 11 into the enlarged hole section. The slurry and the anchoring units solidify to form an anchoring structure, improving the anchoring strength of the anchor rod 2 within the slope. During the pouring, the slurry can be shaken by the shaking component, causing the anchoring units to push the slurry, making the filling more compact. The slurry is quick-drying cement.

[0032] Furthermore, the anchoring unit includes an upper anchor plate 13 and a lower anchor plate 12 that are hinged to each other at their ends. The other end of the lower anchor plate 12 is hinged to the bottom end of the window 11, and the other end of the upper anchor plate 13 is hinged to the rod body of the drive rod 5.

[0033] It should be explained that, in the initial state, the upper anchor plate 13 and the lower anchor plate 12 are in a nearly collinear state. The shaking component drives the drive rod 5 to shake up and down, causing the upper anchor plate 13 and the lower anchor plate 12 to extend radially in a V-shape. The up and down shaking of the drive rod 5 drives the upper anchor plate 13 and the lower anchor plate 12 to reciprocate, pushing the surrounding cast-in-place material to move, making the cast-in-place material fill more densely in the expanded hole section and achieving a better casting effect.

[0034] Furthermore, the upper part of the drive rod 5 has an external thread structure;

[0035] The shaking component includes: a connecting compartment 4, which is a coverless structure;

[0036] A floating plate 7 is slidably installed in the body of the connecting chamber 4. A threaded sleeve is provided through the middle of the upper end of the floating plate 7, and the threaded sleeve is threadedly connected to the drive rod 5.

[0037] The lower end of the floating plate 7 is connected to the bottom of the connecting chamber 4 by multiple springs 9.

[0038] In the initial state, the floating plate 7 is flush with the top of the connecting compartment 4.

[0039] Furthermore, the springs 9 are arranged in a circular pattern, and a telescopic sleeve 10 is coaxially arranged on the inner side of the circumference of each spring 9. The two ends of the telescopic sleeve 10 are respectively connected to the lower end of the floating plate 7 and the bottom of the connecting chamber 4.

[0040] Furthermore, a casting hole 8 is provided on the floating plate 7 between the threaded sleeve and the telescopic sleeve 10.

[0041] In other words, by connecting the drive rod 5 to the floating plate 7 via a threaded connection, during pouring, the pouring device is connected to the pouring hole 8, and then the floating plate 7 is pressed back and forth to compress the spring 9, causing the drive rod 5 to move up and down back and forth, thereby realizing the pushing of the anchoring unit on the poured material and improving the pouring effect.

[0042] Specifically, the telescopic sleeve 10 includes an inner sleeve and an outer sleeve, which are slidably and sealed together. The inner sleeve and the outer sleeve are respectively fixed to the lower end of the floating plate 7 and the bottom of the connecting chamber 4 to avoid the pouring material affecting the reset of the spring 9.

[0043] Furthermore, a guide cylinder is provided at the lower end of the floating plate 7, and the guide cylinder slides in cooperation with the inner wall of the connecting chamber 4 to guide the floating plate 7 when it rises and falls.

[0044] Furthermore, a number of fixing ears 14 are evenly distributed on the top of the outer periphery of the connecting compartment 4 for connecting with the support structure 1;

[0045] Preferably, the outer end of the drive rod 5 has a screw-in structure or a rotating handle.

[0046] In practice, several installation holes are pre-drilled on the vertical slope surface using a drilling device, and multiple enlarged sections are drilled axially within these holes, corresponding to the anchoring units. Anchor rods are placed in the installation holes, and each anchoring unit is anchored within its corresponding enlarged section using a drive rod. Then, a pouring device is used to pour the slurry through a pouring channel and window into the enlarged section, where the slurry and anchoring units solidify to form the anchoring structure. Simultaneously, a shaking component agitates the slurry, causing the anchoring units to push the slurry, resulting in a more compact filling.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
