Description

Technical Field

[0001] This utility model relates to the field of wire rope anchoring structure design, specifically a combined wire rope anchoring structure suitable for slopes. Background Technology

[0002] While traditional gravity, tunnel, and rock-anchored anchorage structures are widely used in wire rope anchorage systems, they face significant challenges when constructed on steep slopes with harsh geological conditions. Gravity anchorages rely on large volumes of concrete to provide horizontal resistance, requiring extensive slope excavation and concrete pouring. This not only results in long construction periods and high costs but also increases the risk of slope instability, potentially inducing landslides on steep slopes or in soft strata. Tunnel anchorages require the excavation of deep, long tunnels embedded in rock strata, placing stringent requirements on geological integrity. Support costs increase dramatically in fractured rock masses or soil slopes, and the complex underground operations are prone to collapse accidents, making project timeline control difficult. While rock-anchored anchorages are relatively lightweight, they are highly dependent on the strength and integrity of the rock mass. In weathered rock strata or mixed soil-rock slopes, the anchoring force is easily weakened, resulting in poor long-term deformation adaptability and potential anchor cable failure.

[0003] These traditional technologies share the following limitations: large-scale excavation and concrete pouring result in huge resource inputs, and geological disturbances can easily exacerbate the risk of slope instability; their adaptability to stable rock masses or flat sites is insufficient for complex steep slopes and weak geological conditions; furthermore, traditional wire rope anchoring processes are cumbersome, have unclear force transmission paths, and weak deformation coordination capabilities, further restricting construction safety and efficiency. Especially in steep and fractured slope environments, high construction costs, uncontrollable safety risks, and limited geological adaptability have become prominent bottlenecks restricting the application of anchoring technology.

[0004] Therefore, there is an urgent need for an anchoring solution that combines lightweight construction, low environmental disturbance, and strong geological adaptability to overcome the technical difficulties of anchoring construction in steep slope areas in an economical and safe manner. Utility Model Content

[0005] This invention overcomes the shortcomings of existing technologies by providing a combined wire rope anchorage structure suitable for slopes. It solves the problems of high cost and high risk encountered when constructing anchorages on steep slopes with poor geological conditions. Simultaneously, its innovative wire rope anchoring method significantly improves the simplicity and safety of the anchoring process.

[0006] To achieve the above objectives, a combined wire rope anchorage structure suitable for slopes is designed, comprising an anchor platform, characterized in that: a rock anchor bundle is installed inside the anchor platform, a steel pipe pile is installed at the bottom of the anchor platform, a turning pipe is installed inside the anchor platform, a vertical support block is installed at the orifice of the turning pipe, a wire rope is threaded inside the turning pipe, the joints of the wire rope are connected by rope clamps, and a lateral limiting clamp is installed between the wire ropes.

[0007] Furthermore: the rock anchor bundle is made of prestressed steel strand, prestressed steel bar or other suitable materials, with one end deeply embedded in the rock and soil for secure anchoring, and the other end tensioned and anchored to the outer surface of the anchor platform, mainly used to bear the horizontal tension generated by the wire rope.

[0008] Furthermore: the top of the steel pipe pile is embedded in the bottom of the anchor platform, mainly to bear the self-weight of the anchor platform structure, the vertical component force generated by the rock anchor bundle and the vertical component force generated by the wire rope.

[0009] Furthermore: the steering tube is embedded inside the anchor platform, forming a cavity inside the anchor platform.

[0010] Furthermore, the vertical support block is arranged below the outlet of the steering pipe and anchored to the outer surface of the anchor platform to provide steering and vertical support for the wire rope.

[0011] Furthermore, the wire rope passes through the cavity formed by the steering tube and is anchored by wrapping around it.

[0012] Furthermore, the rope clamp is mainly used for splicing the ends of the wire rope near the anchorage to form a double-strand structure.

[0013] Furthermore, the lateral limiting clamp is mainly used for the coiling of the double-strand steel wire rope near the anchorage to ensure the distance between the two strands.

[0014] The beneficial effects of this utility model are specifically manifested as follows:

[0015] 1. Enhanced structural efficiency and slope stability. The modular structural design is simple and lightweight, with a clear force transmission path, avoiding redundant design and improving overall load-bearing efficiency. At the same time, by reducing the scale of excavation and the volume of anchorages, it significantly reduces disturbance to the slope, effectively preventing slope instability or environmental damage, and is especially suitable for steep slope areas with poor geological conditions.

[0016] 2. Optimize the wire rope anchoring method for simplified and safe construction. The wire rope loop anchoring method has a simple structure, facilitates rapid on-site installation and adjustment, and is convenient and efficient to operate, reducing technical difficulty and the risk of human error. Its excellent adaptability to deformation can effectively cope with uneven slope settlement or geological deformation, enhancing the reliability and durability of the anchoring system.

[0017] 3. Significantly reduced construction costs and risks. The substantial reduction in the size of the anchorage avoids the large-scale excavation work required by traditional anchorages, effectively reducing the costs of materials, manpower, and machinery. This structure also simplifies the construction process and significantly reduces safety hazards (such as the risk of landslides or collapses) when operating in complex geological environments.

[0023] like Figure 1-3 As shown, this utility model provides a combined steel wire rope anchor structure suitable for slopes: a rock anchor bundle 2 is set inside the anchor platform 1, a steel pipe pile 3 is set at the bottom of the anchor platform 1, a turning pipe 4 is set inside the anchor platform 1, a vertical support block 5 is set at the opening of the turning pipe 4, a steel wire rope 6 is threaded inside the turning pipe 4, the joints of the steel wire rope 6 are connected by rope clamps 7, and a lateral limiting clamp 8 is set between the steel wire ropes 6.

Then, the steel cage of the anchor platform 1 is tied, and the turning pipe 4 and vertical support block 5 are pre-embedded, and isolation measures are taken between the rock anchor bundle 2 and the anchor platform 1. Then, the formwork is erected and the concrete of the anchor platform 1 is poured. After curing to the design strength, the formwork is removed. Next, the rock anchor bundle 2 is tensioned and its exposed end is anchored to the outer surface of the anchor platform 1. Finally, the wire rope 6 is passed through the turning pipe 4 and supported on the vertical support block 5. The rope clamp 7 and the lateral limiting clamp 8 are used to achieve the overlap and distance control of the wire rope 6 ends. The installation is completed by adjusting the posture of the wire rope 6.

Compared with existing technologies, this structure effectively solves the problems of high cost and high risk faced when anchoring in steep slopes with poor geological conditions. Simultaneously, its innovative wire rope anchoring method significantly improves the simplicity and safety of the anchoring process.

Furthermore, the wire rope wrapping anchoring method adopted is characterized by simple construction, convenient operation, and strong adaptability to deformation. In summary, this invention provides a practical, safe, and economical solution for wire rope anchoring in steep slope areas with harsh geological environments.
