Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a slope protection structure. Background Technology

[0002] In the construction of roads and bridges, the strength and stability of the roadbed directly affect the overall quality of the project. A key aspect of roadbed protection construction is slope protection, which primarily addresses roadbeds formed during the filling and excavation of soil and rock masses. When slopes deform or shift due to factors such as slope stability, natural elements, and changes in the physical and mechanical properties of the soil and rock, leading to damage, slope protection construction techniques are necessary.

[0003] Currently, the engineering protection types for slopes include rubble slope protection, concrete block slope protection, and shotcrete slope protection.

[0004] The applicant has discovered certain deficiencies in the existing engineering protection applications and environmental beautification aspects, mainly as follows:

[0005] Stone slab slope protection is only suitable for relatively stable soil layers and rock slopes. It is not suitable for steep slopes or slopes with unstable soil, and has certain limitations. Examples include red clay and soils with high liquid limit.

[0006] Concrete block slope protection has drawbacks such as high unit price of concrete blocks, limited block size, and long construction time for block laying.

[0007] Shotcrete slope protection involves hanging netting and spraying grout onto the slope, but it has certain drawbacks in terms of beautifying the environment along the project route and enhancing the aesthetic value of the project. Utility Model Content

[0008] The purpose of this utility model is to provide a slope protection structure that can improve slope stability, has strong adaptability and beautifies the environment, shorten construction time and save costs, and ensure that ecological and environmental geological problems such as debris flow, landslide and vegetation destruction will not be caused by the destruction of slope stability.

[0009] The various technical effects of the preferred technical solutions among the many technical solutions provided by this utility model are described in detail below.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] This utility model provides a slope protection structure, comprising:

[0012] The skeleton structure includes multiple beam bodies, each beam body having splicing grooves at both ends, and prestressed anchor cable reserved holes on the beam body;

[0013] Multiple assembly joints are disposed within the skeleton structure. Each assembly joint includes a body, and the outer periphery of the body is provided with multiple flanges extending outward toward the outer side of the body. The flanges can be connected to the splicing groove. The body is provided with the prestressed anchor cable reserved hole.

[0014] Preferably, the splicing groove is configured as a "U"-shaped groove opened along the end face of the beam body to the inner side of the beam body.

[0015] Preferably, the width of the "U"-shaped groove is 1 / 2 of the width of the main beam body.

[0016] Preferably, the body adopts a square structure, and the flanges are disposed on four surfaces of the body in a cross shape, with the flanges located in the middle of their respective surfaces.

[0017] Preferably, the prestressed anchor cable pre-drilled hole is located at the center of the body.

[0018] Preferably, the diameter of the prestressed anchor cable reserved hole is 5cm.

[0019] Preferably, mounting holes are provided on the beam body.

[0020] This utility model provides a slope protection structure that connects multiple beams via assembly joints, forming a skeleton structure. Pre-drilled holes for stress anchor cables are provided at both the assembly joints and the beams, resulting in strong structural stability and effectively preventing damage and collapse of roads or other buildings caused by natural disasters such as debris flows and landslides. It is applicable to slope protection with different soil types and slope ratios, providing both slope protection and environmental beautification. Under the same conditions, it can replace traditional shotcrete and riprap slope protection measures. Using this slope protection structure improves slope stability, shortens construction time, and saves costs. Attached Figure Description

[0032] in, Figure 2 This is a schematic diagram of the skeleton structure in this embodiment, as shown below. Figure 1 As shown, the skeleton structure 1 in this embodiment includes multiple beam bodies 10, and each beam body 10 has splicing grooves 100 at both ends. Optionally, prestressed anchor cable reserved holes 30 are provided on the beam body.

[0033] Figure 3 This is a schematic diagram of the assembly joint in this embodiment. Figure 4 This is a schematic diagram of the connection between the assembly joint and the main beam in this embodiment, as shown below. Figure 3 and Figure 4 As shown, the slope protection structure is provided with multiple assembly joints 2, and all of the multiple assembly joints 2 are located within the frame structure 1.

[0034] The assembly joint 2 in this embodiment includes a body 20. Multiple flanges 200 extending outwards from the outer periphery of the body 20 are provided, and the flanges 200 can connect to the splicing groove 100. Furthermore, prestressed anchor cable pre-drilled holes 30 are provided on the body 20.

[0035] This slope protection structure connects multiple beam bodies 10 through assembly joints 2, forming a skeleton structure. Prestressed anchor cable reserved holes 30 are provided on both the assembly joints 2 and the beam bodies 10. When in use, it can improve the stability of the slope, has strong adaptability, beautify the environment, shorten the construction time, save costs, and ensure that ecological and environmental geological problems such as debris flow, landslides, and vegetation destruction will not be caused by the destruction of slope stability.

[0036] Preferably, in this embodiment, the prestressed anchor cable reserved hole 30 is located at the center of the body 20, and the diameter of the prestressed anchor cable reserved hole 30 is 5cm, to ensure the smooth progress of construction.

[0037] As an optional implementation, the splicing groove 100 is configured as a "U"-shaped groove opened along the end face of the beam body 10 to 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.

[0038] In this embodiment, the width of the "U"-shaped groove is half the width of the main beam 10. This design ensures both efficient installation and strong connection, thereby improving the stability of the slope protection structure.

[0039] As an optional implementation, the body 20 adopts a square structure, and the flanges 200 are disposed on the four surfaces of the body 20 in a cross shape, with the flanges 200 located in the middle of their respective surfaces.

[0040] This arrangement serves two purposes: firstly, it ensures that the main beam 10 is installed in the middle of the body 20, improving the overall structural stability; secondly, since the flanges 200 are arranged on the four surfaces of the body 20 in a cross shape, the overall structure can be arranged in a regular manner, providing slope protection while enhancing aesthetics and beautifying the environment.

[0041] During the construction of highway subgrade protection, different subgrade protection measures need to be selected and applied according to different geological conditions and environmental characteristics to ensure the applicability and effectiveness of the adopted construction measures.

[0042] Therefore, this embodiment provides a construction method for the above-mentioned slope protection structure. This method adopts the construction process of prefabricated prestressed anchor cable assembly frame. The start and end time of frame prefabrication can be combined with the construction schedule so that the prefabricated components can be installed in a timely manner after the roadbed slope is formed.

[0043] Figure 5 This is a construction flowchart of an embodiment, such as... Figure 5 As shown, the construction method for slope protection structures specifically includes the following steps:

[0044] S1: Determine the planar location of the slope protection structure;

[0045] In this embodiment, the planar positions of the prefabricated frame and the cast-in-place frame are first determined according to the design drawings, and a plan view of the prefabrication and installation of the prefabricated frame is drawn. It is ensured that the construction of the roadbed slope, frame prefabrication, and frame installation meet the design and specification requirements. The start and end time of frame prefabrication can be combined with the construction schedule so that the prefabricated components can be installed in a timely manner after the roadbed slope is formed.

[0046] S2: Components of a prefabricated slope protection structure, including multiple prefabricated beam bodies 10 and multiple assembly joints 2 according to the required plan position of the slope protection structure;

[0047] In this embodiment, before construction, the main beam 10 and the assembly joint 2 of the slope protection structure are prepared according to the design drawings and the drawn plan.

[0048] The precast frame can be constructed according to the following process: site construction -- cleaning the formwork and applying the release agent -- mixing concrete -- vibrating on a plate vibrating table -- surface finishing -- automatic spray curing -- demolding -- finished product curing. The geometric dimensions of the precast components and the reserved positions of the anchor cable holes must meet the design and specification requirements. The precast components should also be numbered according to the frame installation diagram. After demolding, all components should be matched with their numbers and stacked in sections to guide the transportation and installation of the components.

[0049] S3: Installing components of prefabricated slope protection structures, including installing components of prefabricated slope protection structures on slopes that need protection to form slope protection structures;

[0050] In this embodiment, after the slope is formed, the slope surface is trimmed according to the design requirements. Preparatory work includes marking out anchor cable locations, drilling, anchor cable fabrication and installation, grouting, slope trenching, and pouring of the base concrete, all based on the design drawings and plan. Once everything is ready, the prefabricated components are installed according to the design drawings and plan.

[0051] S4: After installation, the anchor cables are prestressed and locked on the slope protection structure as required;

[0052] S5: Grout the gaps between components in the slope protection structure and perform secondary grouting on the gaps between the components and the slope surface.

[0053] Specifically, in this embodiment, after the anchor cable is locked, the gaps between the components are first filled, and then the gaps between the components and the slope are grouted again to ensure that the precast components are closely attached to the slope and there are no voids. After the frame installation is completed, the slope soil should be shaped immediately, and the leveled slope should be manually compacted to ensure that the soil does not slide automatically and the particles do not roll off.

[0054] As an optional implementation method, after the construction is completed, grass planting protection is carried out on the skeleton structure 1.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
