Description

Technical Field

[0001] The invention relates to the technical field of geological disaster prevention and control structures, and in particular to a slope interception structure used for geological disaster prevention and control. Background Art

[0002] Geological disaster prevention and control refers to the assessment of adverse geological phenomena, and the use of effective geological engineering techniques to change the process of these geological disasters in order to prevent or reduce the occurrence of disasters; geological disaster prevention and control work is carried out in accordance with the principle of prevention first, avoidance and control, and the principles of prevention first, prevention and control combined, comprehensive planning and comprehensive management. The slope interception structure of geological disaster prevention and control refers to a series of measures taken on the slope to prevent geological disasters such as landslides and mudslides from occurring on the slope. Common slope interception structures include retaining walls, slope protection, stone retaining nets, vegetation covers, etc.

[0003] Based on the above, the inventors have found that the existing slope interception structure for geological disaster prevention and control mainly has the following shortcomings. For example, when the existing slope interception structure is impacted by a debris flow, since the debris flow contains a large amount of water, the impact of the debris flow is relatively large, making the interception structure prone to loosening or collapse after the impact, reducing the effect of blocking stones in the debris flow. Summary of the invention

[0004] In view of the above problems, the present invention provides a slope interception structure for preventing and controlling geological disasters.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a slope interception structure for geological disaster prevention and control, the structure of which includes a slope and a main body, the end surface of the slope is installed with the main body, the main body includes an interception structure, a steel cable, and a support rod, the interception structure is provided with three groups, and the interception structure is equidistantly installed in the slope, the support rod is provided with three groups of two each, and the support rods are installed on both side end surfaces of the interception structure; The angle formed by the support rod and the interception structure is 30 degrees, and the support rod is inserted into the inside of the slope in a T shape; The interception structure includes a support column, a fixed card seat, a buffer structure, a through groove, a guide roller, and an interception mesh surface. The support column is provided with two, and three fixed card seats are provided inside the support column, and the fixed card seats are arranged around the inner end surface of the support column. The buffer structure is mounted in the fixed card seat, and the through groove is located at the side end of the support column. There are two guide rollers, and the guide rollers are vertically installed on both sides of the through groove, and the guide rollers are rotatably connected to the through groove. The top two sides of the interception mesh surface are connected to the two buffer structures, and the bottom two sides of the interception mesh surface are fixedly connected to the support column; The buffer structure includes a support tube, a winding shaft, a speed reducer, a friction structure, a steel wire rope, an insertion block, and a ball bearing. The side end of the support tube is provided with three insertion blocks, and the support tube is mounted on the end surface of the fixed clamping seat through the insertion block. The winding shaft is rotatably connected to the inside of the support tube, and the ball bearing can increase the smoothness of the rotation of the winding shaft. The friction structure is installed at the bottom end of the inner part of the support tube, and the friction structure is movably matched with the speed reducer. The steel wire rope is wound on the end surface of the winding shaft. The friction structure includes a threaded seat, a threaded rod, a rotating head, and a second speed reducer. The threaded seat is fixedly mounted on the bottom end surface of the support tube, the threaded rod is threadedly matched with the threaded seat, the rotating head is fixedly connected to the bottom of the threaded rod, and the second speed reducer is fixedly connected to the top end surface of the threaded rod. By setting up three groups of interception structures on the slope, the debris flow can be blocked at the first, second and third levels. The debris flow can be intercepted by the first two interception structures to reduce the impact force, and then the debris flow can be intercepted by the last interception structure. The second speed reducer will rub against the first speed reducer at the bottom of the winding shaft, and then the interception net surface can be pulled by the wire rope to rotate the winding shaft, so that the interception net surface can be buffered after being impacted by the debris flow, preventing the interception net surface from being affected by the large impact force of the debris flow and causing the supporting column to collapse.

[0006] Furthermore, the intercepting net surface includes a frame, a support frame, a wire mesh, a hanging ear, and a fixed shaft. The frame is rectangular in shape, and fixed shafts are provided on both sides of the bottom of the frame. The fixed shaft is rotatably connected to the end faces of the support column, and the hanging ears are arranged on the tops of both sides of the frame and connected to the wire ropes. The support frame is connected to the upper and lower end faces of the frame, and the wire mesh is arranged on the end face of the frame. When the wire mesh is impacted by a mudslide, the wire mesh can be buffered by pulling the wire rope to extend.

[0007] Furthermore, the support frame is in a cross shape, which can improve the overall firmness of the frame.

[0024] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows: Its structure includes a slope 1 and a main body 2. The end surface of the slope 1 is installed with the main body 2. The main body 2 includes an interception structure 21, a steel cable 22, and a support rod 23. The interception structure 21 is provided in three groups, and the interception structure 21 is equidistantly installed in the slope 1. The support rod 23 is provided in three groups, each group has two, and the support rods 23 are installed on both side end surfaces of the interception structure 21. The angle formed between the support rod 23 and the interception structure 21 is 30 degrees, and the support rod 23 is T-shaped and inserted inside the slope 1; The interception structure 21 includes a support column 211, a fixed card seat 212, a buffer structure 213, a through groove 214, a guide roller 215, and an interception mesh surface 216. The support column 211 is provided with two, and three fixed card seats 212 are provided inside the support column 211. At the same time, the fixed card seats 212 are arranged around the inner end surface of the support column 211. The buffer structure 213 is clamped and installed in the fixed card seat 212. The through groove 214 is located at the side end of the support column 211. There are two guide rollers 215, and the guide rollers 215 are vertically installed on both sides of the through groove 214. At the same time, the guide rollers 215 are rotatably connected to the through groove 214. The top two sides of the interception mesh surface 216 are connected to the two buffer structures 213, and the bottom two sides of the interception mesh surface 216 are fixedly connected to the support column 211. The buffer structure 213 includes a support tube 2131, a winding shaft 2132, a speed reducer 2133, a friction structure 2134, a steel wire rope 2135, an insertion block 2136, and a ball 2137. The side end of the support tube 2131 is provided with three insertion blocks 2136, and the support tube 2131 is mounted on the end surface of the fixed base 212 through the insertion blocks 2136. The winding shaft 2132 is rotatably connected to the inside of the support tube 2131, and the ball 2137 can increase the smoothness of the rotation of the winding shaft 2132. The friction structure 2134 is installed at the inner bottom end of the support tube 2131, and the friction structure 2134 is movably matched with the speed reducer 2133. The steel wire rope 2135 is wound on the end surface of the winding shaft 2132. The friction structure 2134 includes a threaded seat 41, a threaded rod 42, a rotating head 43, and a second speed reducer 44. The threaded seat 41 is fixedly mounted on the bottom end surface of the support tube 2131, the threaded rod 42 is threadedly matched with the threaded seat 41, the rotating head 43 is fixedly connected to the bottom of the threaded rod 42, and the second speed reducer 44 is fixedly connected to the top end surface of the threaded rod 42. By setting up three groups of interception structures 21 on the slope 1, the debris flow can be blocked at the first level, the second level and the third level. The debris flow can be intercepted by the first two interception structures 21 to reduce the impact force, and then the debris flow can be intercepted by the last interception structure 21, and the deceleration plate 2 44 is used to rub against the deceleration plate 1 2133 at the bottom of the winding shaft 2132, so that the interception net surface 216 can be pulled by the wire rope 2135 to rotate the winding shaft 2132, so that the interception net surface 216 can be buffered after being impacted by the debris flow, thereby preventing the interception net surface 216 from being subjected to the large impact force of the debris flow and causing the support column 211 to collapse.

[0025] Based on the above embodiment, the specific working principle is as follows: three groups of interception structures 21 are set up on the slope 1, which can perform primary, secondary and tertiary blocking on the debris flow. The first two interception structures 21 can be used to intercept the debris flow and reduce the impact force, and then the last interception structure 21 can be used to intercept the debris flow, and the support rod 23 supports the interception structure 21, which can improve the overall stability of the interception structure 21 and improve the impact resistance of the interception structure 21. When the interception structure 21 is impacted by the debris flow, the deceleration plate 2 44 can be used to rub against the deceleration plate 1 2133 at the bottom of the winding shaft 2132, thereby The intercepting net 216 is rotated by pulling the winding shaft 2132 through the wire rope 2135, so that the intercepting net 216 can be buffered after being impacted by the mud and rock flow, preventing the intercepting net 216 from being subjected to a large impact force of the mud and rock flow and causing the support column 211 to collapse. The threaded rod 42 is driven by the rotating head 43 to rotate upward, and the threaded rod 42 can drive the speed reducer 2 44 to increase the friction between the speed reducer 1 2133, so that the winding shaft 2132 needs to be subjected to a larger pulling force from the wire rope 2135 to rotate, thereby allowing the intercepting net 216 to withstand a larger mud and rock flow impact, thereby improving the intercepting effect of the mud and rock flow.

[0026] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows: The intercepting mesh surface 216 includes a frame 31, a support frame 32, a wire mesh 33, a hanging ear 34, and a fixed shaft 35.

At the same time, the fixed shaft 35 is rotatably connected to the end surface of the support column 211, and the hanging ears 34 are arranged on the top of both sides of the frame 31 and connected to the wire rope 2135. The support frame 32 is connected to the upper and lower end surfaces of the frame 31, and the wire mesh 33 is arranged on the end surface of the frame 31; the side of the wire mesh 33 is supported by the frame 31.

[0027] The support frame 32 is in a cross shape, which can improve the overall firmness of the frame 31 .

[0028] The frame 31 is in the shape of a folded iron sheet.

[0029] The wire mesh 33 is clamped by the frame 31 and two gaskets 36 , and then the wire mesh 33 is locked to the inner side of the frame 31 by bolts 37 ; the frame 31 can protect the wire mesh 33 .

[0030] The fixed shaft 35 can support the frame 31 to rotate on the end surface of the support column 211 .

[0031] Based on the above embodiment, the specific working principle is as follows: the side of the wire mesh 33 is supported by the frame 31, and then connected to the wire rope 2135 in the buffer structure 213 through the ear 34. When the wire mesh 33 is impacted by a debris flow, the wire mesh 33 can be buffered by pulling the wire rope 2135 to extend, and the frame 31 protects the wire mesh 33, thereby preventing the wire mesh 33 from being torn by the debris flow, thereby improving the strength of intercepting the debris flow.
