Description

Technical Field

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

[0002] With the continuous advancement of highway construction, the stability and safety of slopes have become an increasingly important issue. In areas with complex geological conditions and variable climates, slope disasters (such as landslides, collapses, and rockfalls) occur frequently, seriously threatening the safety and smooth flow of highway traffic. These disasters not only cause huge economic losses but may also threaten the lives of the people.

[0003] Traditional slope protection structures, such as retaining walls and slope protection, can resist slope disasters to a certain extent, but they have many limitations. In order to overcome the limitations of traditional protection structures, flexible protection technology has developed rapidly in recent years. However, protective nets may be damaged or broken during the process of protecting against rockfalls, which requires the replacement of the protective net. However, the entire protective net needs to be replaced, which not only wastes costs, but also increases the workload of replacement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flexible protection structure for highway slope disaster management. When the intercepting wire mesh is damaged, the corresponding anchor rods can be removed to facilitate the replacement of the damaged intercepting wire mesh without the need for complete replacement, thus greatly reducing costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible protection structure for highway slope disaster management includes multiple fixed rings, with steel wire cables fixedly connected between every two adjacent fixed rings, and a wire mesh for interception fixedly connected between the multiple steel wire cables.

[0007] A fixing seat is provided on the fixing ring, and an anchor rod is provided through the fixing seat. Multiple limiting components for limiting the fixing ring are provided at equal intervals on the side of the fixing seat facing the fixing ring.

[0008] Preferably, the fixing seat has a through hole adapted to the anchor rod, and the anchor rod is located in the through hole.

[0009] Preferably, the limiting component includes an arc-shaped plate fixedly installed on the side wall of the fixed base, an arc-shaped groove is provided on the inner side of the arc-shaped plate, an arc-shaped sliding plate is slidably connected to the inner side of the arc-shaped groove, and an extension plate is fixedly installed at the lower end of the arc-shaped sliding plate.

[0010] Preferably, the arc-shaped sliding plate and the fixed base are elastically connected by a return spring.

[0011] Preferably, the cross-section of the arc-shaped groove is a T-shaped structure to prevent the arc-shaped slide from detaching from the arc-shaped groove.

[0012] Preferably, a gap is left between the fixing ring and the intercepting wire mesh to facilitate the insertion of the extension plate into the gap, which can restrict the fixing ring.

[0013] This utility model has the following beneficial effects:

[0014] 1. Through the initial interception of the steel wire mesh and the joint bearing of the grid structure formed by the fixing rings and steel wire cables, this structure can efficiently intercept falling rocks on the slope and disperse the impact force into the slope soil or rock, effectively reducing the potential threat to the slope and the road or building below.

[0015] 2. When assembling multiple wire mesh interception rings, install multiple aligned fixing rings (up to four) together on a fixing base and secure them with anchor bolts. This installation method not only simplifies the construction process and improves installation efficiency, but also ensures the stability and reliability of the fixing base.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1-3 A flexible protection structure for highway slope disaster management includes multiple fixed rings 1, with steel wire cables 2 fixedly connected between each pair of adjacent fixed rings 1, and a common intercepting steel wire mesh 3 fixedly connected between the multiple steel wire cables 2. A gap is left between the fixed rings 1 and the intercepting steel wire mesh 3 to facilitate the insertion of extension plates 6 into the gap, which can restrict the fixed rings 1.

[0023] The fixed ring 1 serves as the basic support structure, interconnected by steel wire cables 2 to form a stable grid structure. The intercepting wire mesh 3 is fixed between the multiple steel wire cables 2, forming an initial interception of falling rocks on the slope. A gap is left between the fixed ring 1 and the intercepting wire mesh 3 to facilitate the subsequent installation of the extension plate 6 for further fixation and restraint.

[0024] A fixing seat 4 is provided on the fixing ring 1, and an anchor rod 5 is installed through the fixing seat 4. A through hole adapted to the anchor rod 5 is provided through the fixing seat 4. The anchor rod 5 is located in the through hole. The anchor rod 5 is inserted into the slope soil or rock to achieve the stable installation of the fixing ring 1 and ensure the firm connection between the fixing seat 4 and the slope.

[0025] The fixed base 4 is provided with multiple limiting components at equal intervals on the side facing the fixed ring 1 to limit the fixed ring 1. The limiting components include an arc-shaped plate 7 fixedly installed on the side wall of the fixed base 4. An arc-shaped groove 9 is provided on the inner side of the arc-shaped plate 7. The cross-section of the arc-shaped groove 9 is a T-shaped structure to prevent the arc-shaped slide plate 8 from falling out of the arc-shaped groove 9. The arc-shaped slide plate 8 is slidably connected to the inner side of the arc-shaped groove 9. An extension plate 6 is fixedly installed at the lower end of the arc-shaped slide plate 8. The arc-shaped slide plate 8 and the fixed base 4 are elastically connected by a return spring 10 to provide a return force for the arc-shaped slide plate 8 so that it can return to its initial position after being subjected to external force.

[0026] Working principle:

[0027] When a slope encounters a disaster, falling rocks are initially blocked by the intercepting wire mesh 3. If the impact force of the falling rocks is strong, the grid system composed of the fixing rings 1 and the wire cables 2 will work together to bear this force, and the impact force will be effectively dispersed into the soil or rock layer of the slope through the anchor bolts 5;

[0028] During installation, thanks to the elastic force of the return spring 10, the extension plate 6 can automatically extend and slide flexibly along the arc-shaped groove 9 until it is firmly inserted into the reserved gap between the fixing ring 1 and the intercepting wire mesh 3, providing additional support and stability for the fixing ring 1. This design allows up to four relatively aligned fixing rings 1 to be easily installed together on a fixing seat 4 when combining multiple intercepting wire meshes 3, and to achieve efficient and stable fixing through the anchor rod 5.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
