Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a safe and reliable anti-sloughing protection circular net. Background Technique

[0002] Both sloughing and landslides are natural phenomena in which surface rock and soil masses slide downward along a certain weak surface or weak zone under the action of gravity. However, there are certain differences between them in terms of occurrence mechanism, movement characteristics, deposit structure, etc.: 1. Occurrence mechanism: Sloughing mainly occurs on slopes with loose soil and unstable structures. Usually, due to factors such as groundwater activity, earthquakes, and artificial slope cutting, the stability of the soil mass is reduced, thus triggering sliding. Landslides mainly occur when the soil or rock mass on the slope slides downward along a certain weak surface or weak zone as a whole or dispersedly. The reasons for their occurrence include river erosion, groundwater activity, earthquakes, and artificial slope cutting, etc.; 2. Movement characteristics: The movement speed of sloughing is usually relatively fast and occurs suddenly, with greater destructive power. The movement speed of landslides ranges from extremely fast to extremely slow, and its destructive power is also relatively large. However, compared with sloughing, the destructive effect of landslides is relatively slow; 3. Deposit structure: The deposit structure of sloughing is relatively messy and usually conical. Since the sloughing blocks are subject to friction and impact during the sliding process, its structure is relatively loose. The deposit structure of landslides is relatively compact because the landslides have better integrity during the sliding process; 4. Occurrence location: Sloughing mostly occurs on slopes with larger gradients, especially in areas with loose soil. Landslides mostly occur on slopes with gradients below 50 degrees. In short, both sloughing and landslides are phenomena of surface rock and soil mass sliding, but they are different in terms of occurrence mechanism, movement characteristics, deposit structure, etc. In the actual prevention and control process, appropriate prevention and control measures should be selected according to specific situations.

[0003] Currently, the technical means adopted for anti-sloughing of slopes is to use a circular protection net. Since the circular protection net itself has a certain flexibility, it can be used to protect against slope sloughing. However, the circular protection net in the prior art can only rely on its flexibility to intercept the sloughing soil mass. Due to the large potential energy of the sloughing soil mass, large impact forces often cause the installation columns of the protection net to tilt or even be pushed down. At this time, the soil mass is very likely to cross the protection net and rush out. For this reason, we propose a safe and reliable anti-sloughing protection circular net. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide a safe and reliable anti-sloughing protection circular net to solve the technical problems mentioned in the above background.

[0005] To achieve the above object, the present utility model provides the following technical solution: a safe and reliable anti-collapse protection annular net, including an annular net, both sides of the annular net are provided with installation columns, and the installation columns are fixedly installed inside the slope. The outer wall of the annular net is fixedly connected with a first buffer plate, and a second buffer plate is arranged inside the installation column on the outer side of the first buffer plate. A winding shaft is installed inside the second buffer plate, and a connecting part is wound and connected to the outer wall of the winding shaft, and the end of the connecting part is fixedly connected to the end of the first buffer plate.

[0006] By adopting the above technical solution, the collapsed soil can be buffered multiple times, thereby effectively reducing the impact of the collapsed land on the installation column, avoiding the problem of the annular net toppling, and improving the stability and reliability of the annular net.

[0007] The present utility model is further configured such that the first buffer plate is horizontally slidably connected to the end face of the installation column.

[0008] By adopting the above technical solution, it plays an effect of assisting the first buffer plate to move and buffer.

[0009] The present utility model is further configured such that both ends of the winding shaft are connected to the inner wall of the second buffer plate through torsion spring shafts.

[0010] By adopting the above technical solution, it plays an effect of assisting the winding shaft to rotate and reset.

[0011] The present utility model is further configured such that a buffer groove is opened inside the installation column on the outer side of the second buffer plate, and the second buffer plate is horizontally slidably connected to the inner wall of the buffer groove.

[0012] By adopting the above technical solution, it plays an effect of assisting the buffer plate to move and buffer.

[0013] The present utility model is further configured such that the end face of the second buffer plate is connected to a damping spring installed on the inner wall of the buffer groove.

[0014] By adopting the above technical solution, it plays an effect of assisting the second buffer plate to move and reset.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] 1. The utility model realizes the interception and preliminary buffering of soil mass by setting the first buffering structure. When slope sloughing occurs, the sloughing soil mass impacts the annular net. At this time, the annular net will intercept the soil mass and achieve preliminary buffering under its own flexibility. Subsequently, the first buffering component will be triggered. Specifically, under the impact of the soil mass, the annular net will move outward, and the movement of the annular net will drive the connecting part to move by pulling the first buffer plate. At this time, the connecting part will gradually unfold on the outer wall of the winding shaft to assist the movement of the annular net, thereby realizing further buffering of the soil mass, effectively alleviating the load on the installation column, and enabling the installation column to stand stably, that is, improving the stability and reliability of the annular net;

[0017] 2. The utility model sets the second buffering structure on the basis of the first buffering structure, which can not only increase the buffering force but also reduce the occupied space correspondingly, with extremely high practicality. Specifically, when the first buffering structure operates to the limit, the second buffer plate will also move outward with the annular net, and the movement of the second buffer plate will stretch the damping spring to unfold, thereby further buffering the annular net.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0024] The embodiments of the present utility model will be described below according to its overall structure.

[0025] A safe and reliable anti-sloughing protection annular net, as Figures 1-4As shown in the figure, it includes a ring network 1. Installation columns 2 are provided on both sides of the ring network 1, and the installation columns 2 are fixedly installed inside the slope. A first buffer plate 3 is fixedly connected to the outer wall of the ring network 1, and a second buffer plate 4 is arranged inside the installation column 2 on the outer side of the first buffer plate 3. A winding shaft 5 is installed inside the second buffer plate 4, and a connecting part 6 is wound and connected to the outer wall of the winding shaft 5, and the end of the connecting part 6 is fixedly connected to the end of the first buffer plate 3;

[0026] Furthermore, in this embodiment, both ends of the winding shaft 5 are connected to the inner wall of the second buffer plate 4 through torsion spring shafts.

[0027] Please refer to Figure 2 , the first buffer plate 3 is horizontally slidably connected to the end face of the installation column 2 to assist the ring network 1 in buffering.

[0028] Please refer to Figures 3-4 , a buffer groove 7 is opened inside the installation column 2 on the outer side of the second buffer plate 4, and the second buffer plate 4 is horizontally slidably connected to the inner wall of the buffer groove 7. A damping spring 8 installed on the inner wall of the buffer groove 7 is connected to the end face of the second buffer plate 4 to assist the ring network 1 in buffering.

[0029] The working principle of the present utility model is as follows: When a landslide occurs on the slope, the landslide soil will impact the ring network 1. At this time, the ring network 1 will intercept and initially buffer the soil under its own flexibility. Subsequently, the first buffer assembly will be triggered. Specifically, under the impact of the soil, the ring network 1 will move outward, and the movement of the ring network 1 will pull the connecting part 6 to move through the first buffer plate 3. At this time, the connecting part 6 will gradually unwind on the outer wall of the winding shaft 5 to assist the movement of the ring network 1, thereby realizing further buffering of the soil, effectively alleviating the load on the installation column 2, so that the installation column 2 can stand stably, that is, improving the stability and reliability of the ring network 1;

[0030] In addition, adding a second buffer structure on the basis of the first buffer structure can not only increase the buffering force but also correspondingly reduce the occupied space, with extremely high practicality;

[0031] Specifically, when the first buffer structure operates to the limit, the second buffer plate 4 will also move outward with the ring network 1, and the movement of the second buffer plate 4 will stretch the damping spring 8 to expand, thereby further buffering the ring network 1.
