Description

Technical Field

[0001] This utility model relates to the field of civil engineering, and in particular to a flexible protection structure for highway slope disaster management. Background Technology

[0002] my country is a mountainous country with widespread mountainous areas in the west and southeast. Slope geological disasters frequently occur along linear projects such as highways and railways. To address this situation, flexible slope protection systems were introduced to my country from abroad in the 1990s (around 1995). The core of these systems is characterized by high-strength flexible nets (such as diamond-shaped steel wire rope nets and ring nets), and the design revolves around two major protection logics: "active reinforcement" and "passive interception".

[0003] However, some existing flexible protection structures for highway slope disaster management typically use anchor bolts and support ropes to cover the slope with a flexible net to reinforce unstable rocks, inhibit weathering and erosion, and limit the range of falling rocks. However, they do not take into account that the anchor bolts may develop internal gaps due to changes in the soil layer, such as rainwater, which can cause the originally firm anchor bolts to fall off.

[0004] Therefore, a flexible protection structure for highway slope disaster management is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flexible protection structure for highway slope disaster management, aiming to improve the problem of anchor bolt loosening and falling off in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flexible protection structure for highway slope disaster management includes an anchor column structure and a rope structure. The anchor column structure includes a fixed disc, on the top surface of which multiple sets of fixed columns are fixedly connected. A drive shaft is rotatably connected between each set of fixed columns. The drive shaft is slidably connected to a hook cable. An anchor rod is fixedly connected to the bottom end of the fixed disc. Several elastic resistance enhancers are fixedly connected to the anchor rod. An anchor drill bit is fixedly connected to the bottom end of the anchor rod. The structure also includes a rope structure, which consists of a horizontal support rope and a vertical support rope fixedly connected. An internal wire mesh is fixedly connected to the horizontal support rope and the vertical support rope.

[0008] As a further description of the above technical solution:

[0009] The elastic resistance enhancer is inserted into the soil layer along with the anchor column structure;

[0010] As a further description of the above technical solution:

[0011] The anchor rod is equipped with a spring;

[0012] As a further description of the above technical solution:

[0013] The hook is designed with right angles.

[0014] As a further description of the above technical solution:

[0015] The bottom surface of the fixed disc is provided with a buckle for securing the auxiliary hook rope;

[0016] As a further description of the above technical solution:

[0017] The elastic resistance booster is fan-shaped;

[0018] This utility model has the following beneficial effects:

[0019] In this invention, an anchor column structure is inserted into a rope structure. Through the cooperation of an elastic resistance enhancer, hook, and spring on the anchor column, once the anchor column is inserted into the soil, the hook rotates via a pivot, securing the external wire mesh to the internal wire mesh fixed to the horizontal and vertical support ropes, thus enhancing the overall structural resistance to pressure. Simultaneously, the elastic resistance enhancer and spring on the anchor column, in the event of soil changes causing the anchor column to detach, expand the contact area and, through flexible bending by the spring, enhance friction.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1 to 5 One embodiment provided by this utility model:

[0029] A flexible protection structure for highway slope disaster management, characterized in that it includes an anchor column structure, which comprises a fixing disc 12. The fixing disc 12 is used to limit the depth of the anchor column insertion into the soil layer and to provide secondary fixation for the inner wire mesh 3 and the outer wire mesh 1. The bottom surface of the fixing disc 12 is provided with a buckle to assist in the fixation of the hook cable 6. Multiple sets of fixing posts 7 are fixedly connected to the top surface of the fixing disc 12 to assist in fixation. Each set of fixing posts 7 is rotatably connected to a drive shaft 5 to assist in movement. The drive shaft 5 is slidably connected to the hook cable 6, and the hook cable 6 is right-angled. A hook rope 6 is used for auxiliary fixation, and the external wire mesh 1 is fixed to the horizontal support rope 2 and the vertical support rope 4. An anchor rod 9 is fixedly connected to the bottom end of the fixing disc 12. The anchor rod 9 controls the insertion depth. A spring 8 is installed inside the anchor rod 9 to increase flexibility. Several elastic resistance enhancers 10 are fixedly connected to the anchor rod 9. The elastic resistance enhancers 10 are fan-shaped and are inserted into the soil layer along with the anchor column structure. The elastic resistance enhancers 10 increase the contact area and increase the friction. An anchor drill bit 11 is fixedly connected to the bottom end of the anchor rod 9 to break through the soil layer.

[0030] It also includes a rope structure, which is fixedly connected by a horizontal support rope 2 and a vertical support rope 4. The horizontal support rope 2 and the vertical support rope 4 are set to enhance the compressive strength of the structure. An internal wire mesh 3 is fixedly connected between the horizontal support rope 2 and the vertical support rope 4. The internal wire mesh 3 is set to assist in resisting pressure and filter falling stones.

[0031] Working principle: The flexible structure for highway slope treatment and protection is arranged according to the location, with horizontal support ropes 2, vertical support ropes 4, and built-in wire mesh 3 forming the first layer of protection, mainly used to bear the initial pressure. Then, an external wire mesh 1 is arranged on this basis for secondary protection, while filtering out falling rocks. After the arrangement is completed, it is fixed with anchor rods. The anchor rods are inserted into the soil layer through the anchor drill bit 11. The fixing disc 12 plays a restraining role. As the anchor rod is inserted, the fixing disc 12 is fixed to the external wire mesh, which enhances the stability of the overall structure. The anchor rod 9 is equipped with a spring 8 and an elastic resistance enhancer 10. When the soil layer slides and shakes, causing the anchor rod to fall outward, the flexibility of the spring 8 and the increased friction of the elastic resistance enhancer 10 will stabilize the structure and enhance its support.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
