[0002] Slope protection refers to engineering measures to protect and reinforce sloping terrain such as mountains, river banks, and roads. Its main purpose is to prevent geological disasters such as landslides, collapses, and scours on the slopes.

[0003] Common slope protection measures include:

[0004] Greening and slope protection: Planting vegetation on the slope to fix the soil through the plant roots, reduce soil erosion and enhance the stability of the slope;

[0005] Stone slope protection: laying stones or bricks and other materials on the slope to form a stone structure to increase the slope's anti-scouring ability;

[0006] Concrete slope protection: pouring concrete on the slope to form a concrete slope protection structure to improve the slope's ability to resist scour and landslides;

[0007] Geogrid slope protection: Use geogrid and other materials to reinforce the slope to increase the stability and anti-scouring ability of the slope;

[0008] Earthwork and stone slope protection: Reinforce and fill earthwork on the slope to form a slope structure and increase the stability of the slope.

[0009] Based on the description of the above slope protection structure, it can be known that the existing concrete slope protection is to directly pour concrete on the slope to form the slope protection surface, but the slope is a soil layer, and only relying on concrete to form the slope surface is prone to expansion of the soil layer due to rain and snow weather, thereby exerting pressure on the concrete formed slope surface, causing the concrete formed slope surface to collapse. Therefore, the present application designs a high-strength multi-module combined slope protection slope protection structure to solve this prior art defect. Utility Model Content

[0016] A locking fixture is provided between the slope protection block and the transverse concrete column; the locking fixture connects the slope protection block and the transverse concrete column as a whole to prevent them from being separated from the slope surface.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-5 A slope protection structure in this embodiment includes a plurality of slope protection blocks 5 laid on the slope surface and a plurality of casting holes 1 drilled on the top of the slope.

[0034] The slope protection block 5 is provided with a vegetation planting hole 14 for planting slope protection vegetation, so as to facilitate the integration of the vegetation roots with the slope body and avoid soil erosion and slope collapse.

[0035] A concrete column 2 is placed in the casting hole 1 , and a plurality of vertically equidistantly distributed plug holes 3 are provided on the concrete column 2 , and transverse concrete columns 4 passing through the slope surface and the slope protection blocks 5 are plugged into the plug holes 3 .

[0036] It should be noted that the concrete columns 2 are distributed at equal distances in the transverse direction, the transverse concrete columns 4 are distributed at equal distances in the vertical direction, and the slope protection blocks 5 are provided with through holes penetrated by the transverse concrete columns 4 .

[0037] In this embodiment, a butt joint structure for connecting and fixing is provided between the concrete column 2 and the transverse concrete column 4. A concrete layer 10 for integrally connecting the concrete column 2 and the transverse concrete column 4 is cast in the casting hole 1.

[0038] It should be noted that the docking structure includes a number of mounting grooves 7 opened inside the concrete column 2 and connected to the socket 3, and a number of locking grooves 6 opened outside the transverse concrete column 4 and corresponding to the mounting grooves 7 one by one.

[0039] Among them, a stainless steel spring 8 is installed in the installation groove 7, and a locking rod 9 inserted into the locking groove 6 is installed at the other end of the stainless steel spring 8. When the stainless steel spring 8 is in a fully extended state, the locking rod 9 and the installation groove 7 are inseparable, the insertion hole 3 is rectangular, and the transverse concrete column 4 is a rectangular parallelepiped. There is a gap between the insertion hole 3 and the transverse concrete column 4, which is convenient for filling the gap between them when pouring the concrete layer 10.

[0040] In this embodiment, a locking fixture is provided between the slope protection block 5 and the transverse concrete column 4 .

[0041] The locking fixture connects the slope protection block 5 and the transverse concrete column 4 as a whole to prevent it from being separated from the slope surface. It should be noted that the locking fixture includes a plurality of threaded barrels 11 embedded and installed on the outside of the transverse concrete column 4 and the slope protection block 5, and a flange 12 laid on the surface of the slope protection block 5, through which a plurality of threaded rods 13 threadedly connected to the threaded barrels 11 in a one-to-one correspondence are passed.

[0042] The length of the threaded tube 11 on the transverse concrete column 4 is five times the length of the threaded tube 11 on the slope protection block 5 .

[0043] The threaded tubes 11 on the transverse concrete column 4 and the threaded tubes 11 on the slope protection block 5 are both distributed in a circular shape with equal distances, taking the center of the flange 12 as the center of the circle.

[0044] The structures involved in the locking fixture are all made of stainless steel to avoid rust and breakage.

[0045] Each slope protection block 5 is penetrated by two transverse concrete columns 4 , and each slope protection block 5 is provided with two vegetation planting holes 14 , which are distributed on the combined joint surface of the plurality of slope protection blocks 5 at equal distances in the transverse and vertical directions.

[0046] The working principle of the above embodiment is:

[0047] The concrete column 2 is inserted into the provided casting hole 1, and the transverse concrete column 4 is inserted into the insertion hole 3 on the concrete column 2, and then the locking rod 9 is pushed to be inserted into the locking groove 6 on the transverse concrete column 4 in accordance with the elastic expansion and contraction effect of the provided stainless steel spring 8, so as to realize the connection and fixation between the concrete column 2 and the transverse concrete column 4;

[0048] Thus, after the concrete column 2 is connected and fixed to the transverse concrete column 4, the gap between the casting hole 1 and the concrete column 2 and the gap at the connection between the concrete column 2 and the transverse concrete column 4 can be filled by pouring a concrete layer 10 into the provided casting hole 1, so that the concrete column 2 and the transverse concrete column 4 are integrally connected and formed, and the locking rod 9 and the locking groove 6 are inserted to improve the connection strength, thereby improving the overall connection strength of the concrete column 2 and the transverse concrete column 4, and further strengthening the strength of the slope protection structure buried in the slope body;

[0049] In addition, by setting a single slope protection block 5 that is passed through the transverse concrete column 4 and by tightening the threaded rod 13 that passes through the flange 12 and threadedly connected with the threaded tube 11 formed in the slope protection block 5 and the transverse concrete column 4, the connection and fixation of the single slope protection block 5 and the transverse concrete column 4 can be achieved, thereby ensuring the slope protection strength of the single slope protection block 5 on the slope surface. At the same time, multiple slope protection blocks 5 are combined and spliced ​​and connected to the transverse concrete column 4 and laid on the slope surface to achieve multi-point slope protection support on the slope surface, thereby improving the slope protection strength. At the same time, it also avoids the phenomenon of thermal expansion and contraction and cracking of the integrated cast concrete slope surface caused by rain and bad weather.
