[0006] Concrete block slope protection, concrete block bricks have high unit prices, and due to the limitations of block size, the construction time of block paving is long and other defects.

[0007] Sprayed anchor slope protection is to hang a mesh and spray grout on the slope, but it has certain defects in beautifying the environment along the project and improving the ornamental value of the project. Summary of the invention

[0008] The purpose of the present invention is to provide a slope protection structure and a construction method thereof, which can not only improve the stability of the slope, have strong adaptability and beautify the environment, but also shorten the construction time and save costs, and ensure that the ecological environment and environmental geology problems such as mudslides, landslides and vegetation destruction will not be caused by the destruction of slope stability.

Optionally, a prestressed anchor cable reserved hole 30 is arranged on the beam body.

[0040] Figure 3 : is a schematic diagram of the structure of the assembled joint in this embodiment, Figure 4 Schematic diagram of the structure of the connection between the assembly joint and the beam body in this embodiment. Figure 3 and Figure 4 As shown, the slope protection structure is provided with a plurality of assembling joints 2 , and the plurality of assembling joints 2 are all arranged in the skeleton structure 1 .

[0041] The assembly joint 2 in this embodiment includes a body 20, and a plurality of flanges 200 extending toward the outside of the body 20 are arranged on the periphery of the body 20, and the flanges 200 can be connected to the splicing groove 100. In addition, a prestressed anchor cable reserved hole 30 is arranged on the body 20.

[0042] This slope protection structure connects multiple beam bodies 10 through an assembly joint 2, and the multiple beam bodies 10 form a skeleton structure. Prestressed anchor cable reserved holes 30 are set on the assembly joints 2 and the beam bodies 10. When used, it can not only improve the stability of the slope, have strong adaptability and beautify the environment, but also shorten the construction time and save costs, ensuring that the ecological environment and environmental geology problems such as mudslides, landslides and vegetation destruction will not be caused by the destruction of slope stability.

[0043] Preferably, the prestressed anchor cable reserved hole 30 in this embodiment is arranged at the center of the main body 20, and the diameter of the prestressed anchor cable reserved hole 30 is 5 cm, so as to ensure the smooth progress of the construction.

[0044] As an optional embodiment, the splicing groove 100 is configured as a "U"-shaped groove opened along the end surface of the beam body 10 toward the inner side of the beam body 10, so that the beam body 10 can be quickly installed and used with the splicing joint 2.

[0045] The width of the "U"-shaped groove in this embodiment is 1 / 2 of the width of the beam body 10. This arrangement can ensure both the efficiency of installation and the connection strength, thereby improving the stability of the slope protection structure.

[0047] Such arrangement, on the one hand, can ensure that the beam body 10 is installed in the middle of the main body 20, thereby improving the stability of the overall structure; on the other hand, since the flanges 200 are arranged on the four surfaces of the main body 20 in a "cross" distribution, the overall structure can be arranged regularly, which has the function of protecting the slope while being more aesthetically pleasing and playing a role in beautifying the environment.

[0048] During the highway roadbed protection construction process, it is necessary to select and apply different roadbed protection construction measures according to different geological conditions and environmental characteristics to ensure the applicability and effectiveness of the adopted construction measures.

[0049] To this end, this embodiment provides a construction method for the above-mentioned slope protection structure. This method adopts the construction technology of prefabricated prestressed anchor cable assembly skeleton. The start and end time of skeleton prefabrication can be combined with the construction schedule so that prefabricated components can be installed in time after the roadbed slope is formed.

[0050] Figure 5 It is a construction flow chart of an embodiment, such as Figure 5 As shown in FIG. 1 , the construction method of the slope protection structure specifically includes the following steps:

[0051] S1: Determine the plane position of the slope protection structure;

[0052] In this embodiment, the plan positions of the prefabricated frame and the cast-in-place frame are first determined according to the design drawings, and the prefabrication and installation plan of the prefabricated frame is drawn, and it is ensured that the construction of the roadbed slope, frame prefabrication, frame installation, etc. meets the design and specification requirements. The start and end time of the frame prefabrication can be combined with the construction schedule so that the prefabricated components can be installed in time after the roadbed slope is formed.

[0053] S2: Prefabricate components of the slope protection structure, including prefabricating a plurality of beam bodies 10 and a plurality of assembly joints 2 according to the plane position of the required slope protection structure;

[0054] In this embodiment, before construction, the beam body 10 and the assembly joint 2 of the slope protection structure are prepared according to the design drawings and the drawn plan.

[0055] The skeleton prefabrication can be constructed according to the construction process of site construction - cleaning the formwork, applying the release agent - mixing concrete - vibrating on a flat vibration table - surface calendering - automatic spray curing - demoulding - finished product curing, and the prefabricated geometric dimensions, anchor cable reserved holes and reserved positions and other parameters must meet the design and specification requirements. The prefabricated components should also be numbered according to the skeleton installation diagram. After demoulding, all components should be placed in the seats and stacked in sections to guide the transportation and installation of the components.

[0056] S3: installing components of the prefabricated slope protection structure, including installing components of the prefabricated slope protection structure on the slope to be protected to form a slope protection structure;

[0057] In this embodiment, after the slope is formed, the slope surface is trimmed according to the design requirements, and the anchor hole location, drilling, anchor cable installation, grouting, slope surface grooving, base concrete pouring and other preparatory work are carried out in combination with the design drawings and plan. After everything is ready, the prefabricated components are installed according to the design drawings and plan.

[0058] S4: After the installation is completed, the anchor cables are prestressed and locked on the slope protection structure as required;

[0059] S5: Grout the gaps between the components in the slope protection structure, and perform secondary grouting on the gaps between the components and the slope surface.

[0060] Specifically, in this embodiment, after the anchor cable is locked, the gaps between the components are first grouted, and then the gaps between the components and the slope are grouted for the second time to ensure that the prefabricated components are tightly attached to the slope without any voids. After the skeleton installation work is completed, the slope soil should be shaped immediately, and the leveled slope should be compacted manually to ensure that the soil does not slide automatically and the particles do not roll off.
