Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and more specifically, to a temporary slope combined protection structure. Background Technology

[0002] With the vigorous advancement of infrastructure construction, new construction projects adjacent to existing projects will become commonplace, especially in railway reconstruction and expansion projects. These projects often require building new railway lines close to existing roadbeds, creating elevation differences between the old and new lines. The new line necessitates excavating the existing railway, but the existing line must remain operational during construction. Therefore, temporary excavation slopes require retaining and protection to minimize deformation and disturbance to the existing railway, ensuring normal operation. The retaining and protection structure should occupy as little land as possible to reduce the scope and severity of disturbance. After the roadbed of the new line is completed, the existing line is excavated and abandoned, and permanent slope works are constructed. Therefore, gravity retaining walls, cantilever retaining walls, and buttress retaining walls are typically not used for temporary slope protection to avoid excessive engineering waste. Ordinary steel sheet piles are commonly used in engineering construction to support and protect temporary slopes. Steel sheet piles are lightweight and easy to construct, but the pile body is relatively thin and the structural rigidity is low. They are prone to deformation when used for temporary excavation slope support, and cannot meet the requirements of normal operation and minimal disturbance of existing railways.

[0003] To meet the safety requirements of geotechnical engineering, especially the temporary excavation slope support engineering of existing projects such as urban railways and intercity railways, the adoption of economical and reliable slope support structures has significant application value and social benefits.

[0004] Therefore, it is necessary to propose a temporary slope protection structure to address the shortcomings of conventional steel sheet pile retaining structures. Utility Model Content

[0005] This utility model provides a temporary slope protection structure to solve the problem that existing ordinary steel sheet pile retaining structures are prone to deformation, resulting in low stability and safety.

[0006] According to one aspect of this utility model, a temporary slope composite protection structure is provided, comprising multiple steel plate groups, anchor rods, and steel sections. The steel plate groups are interconnected to form a steel plate wall. The anchor rods and the steel sections are interleaved and connected to the steel plate groups. The steel sections are arranged along the height direction of the steel sheet piles. Each steel plate group includes a first steel plate and a second steel plate in a U-shape. The free ends of the first steel plate and the second steel plate are bent outward to form a locking buckle. The first steel plate and the second steel plate are interconnected through the locking buckle. The steel section is connected to the bottom end face of the first steel plate. The anchor rod is connected to the bottom end face of the second steel plate of the adjacent steel plate group.

[0007] Based on the above scheme, the preferred option is that the steel section is one of T-shaped steel rail, I-shaped steel rail or I-shaped steel rail.

[0008] Based on the above scheme, the first steel plate and the second steel plate are preferably one of C-shaped, U-shaped and H-shaped steel sheet piles.

[0009] Based on the above scheme, preferably, the second steel plate is provided with an installation hole, the anchor rod is connected to the second steel plate at an incline, one end of the anchor rod is embedded in the slope rock and soil, and the other end of the anchor rod passes through the installation hole and is locked by a bolt.

[0010] Based on the above scheme, preferably, the end of the second steel plate of the steel plate group corresponding to the steel section is welded with a connecting seat with a slot, and the connecting seat is provided with a baffle in a plug-in manner.

[0011] Based on the above scheme, preferably, the baffle and the steel plate group form a receiving cavity, the steel section is set in the receiving cavity, and concrete can be poured in the receiving cavity.

[0012] This utility model discloses a temporary slope protection structure. By driving scrap steel rails or structural steel onto the outside of sheet piles, the rigidity of the support structure is increased, effectively ensuring the stability of existing excavated slopes. Anchor bolts are driven into the sheet piles to effectively control slope deformation. Furthermore, this combined structure is waterproof, suitable for construction along riverbanks, and ensures construction safety for riverside projects. This utility model not only effectively ensures slope stability and strictly controls slope deformation, but also makes full use of scrap steel rails, achieving the effect of waste recycling and meeting the requirements of resource conservation and quality and safety in engineering construction.

[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0029] Please see Figure 1 and combined Figure 2 and Figure 3 As shown, this utility model discloses a temporary slope protection structure comprising multiple steel plate assemblies 1, anchor bolts 2, and structural steel sections 3, as follows: Figure 1 As shown, multiple steel plate groups 1 are interconnected to form a steel plate wall to block the forces of the soil and rock.

[0030] In this invention, the anchor rods 2 and the steel sections 3 are interlocked and connected to the steel plate assembly 1, with the steel sections 3 positioned along the height of the sheet piles to provide strong support for the steel plate wall. Specifically, the steel sections 3 can be made of T-shaped steel rails, I-beams, or I-shaped steel rails. For existing railway line renovation projects, the reuse of scrap steel rails can effectively reduce costs. For geotechnical engineering projects such as transportation and municipal works, T-shaped steel rails, I-beams, etc., can be used.

[0031] The steel plate assembly 1 of this utility model includes a first steel plate 11 and a second steel plate 12 in a U-shape. In practice, the first steel plate 11 and the second steel plate 12 can be processed from C-shaped, U-shaped, or H-shaped steel sheet piles. The free ends of the first steel plate 11 and the second steel plate 12 are bent outward to form a locking buckle 13. The first steel plate 11 and the second steel plate 12 are hinged together through the locking buckle 13 to form the steel plate assembly 1. Adjacent steel plate assemblies 1 are hinged together through the locking buckle 13 to form a steel plate wall, effectively ensuring the stability of the slope of the existing railway line excavation. The tightly connected steel plate wall structure is also waterproof, suitable for construction on the river side, and ensures the construction safety of riverside projects.

[0032] In this invention, the steel section 3 is welded to the bottom end face of the first steel plate 11 of the steel plate group 1, and the anchor rod 2 is connected to the bottom end face of the second steel plate 12 of the adjacent steel plate group 1 to form an effect of external support and internal tension, so as to ensure the stability of the steel plate wall.

[0033] Scrap steel rails or steel sections 3 are driven at irregular intervals on the outside of the steel plate wall of the protective slope. In areas with poor soil and rock properties, large loads, and strict deformation control requirements, the scrap steel rails or steel sections 3 can be driven more densely. The direction of the steel sections 3 is controlled to maximize the use of their stiffness. This structure can increase the stiffness of the support structure and control the deformation of the slope.

[0034] Specifically, the present invention also provides an installation hole 14 on the second steel plate 12, the anchor rod 2 is connected to the second steel plate 12 at an incline, and one end of the anchor rod 2 is embedded in the slope rock and soil, and the other end of the anchor rod 2 passes through the installation hole 14 and is locked by bolts, so as to improve the stability of the slope protection structure and control the amount of slope deformation.

[0035] For locations with relatively loose soil during construction, to improve the supporting effect of the steel plate wall, this invention can also weld a connecting seat 15 with a slot to the end of the second steel plate 12 of the steel plate assembly 1 corresponding to the steel section 3. The connecting seat 15 can be plugged into a baffle 16, which forms a receiving cavity 17 with the steel plate assembly 1. The steel section 3 is placed in the receiving cavity 17, and concrete can be poured into the receiving cavity 17. For details of the structure, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5 As shown.

[0036] By utilizing the structure formed by the receiving cavity 17, the pouring of concrete can effectively further improve the lateral support force of the retaining wall and enhance its stability.

[0037] This utility model discloses a temporary slope protection structure. By driving scrap steel rails or structural steel sections 3 onto the outside of sheet piles, the rigidity of the support structure is increased, effectively ensuring the stability of the existing excavated slope. Anchor bolts 2 are driven into the sheet piles to effectively control slope deformation. Furthermore, this utility model's combined structure is waterproof, suitable for construction along riverbanks, and ensures construction safety for riverside projects. This utility model not only effectively ensures slope stability and strictly controls slope deformation, but also makes full use of scrap steel rails, achieving the effect of waste recycling and meeting the requirements of resource conservation and quality and safety in engineering construction.

[0038] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
