Description

Technical Field

[0001] This application belongs to the field of slope stability technology, and in particular relates to a high-level material source stabilization structure in a geological disaster chain. Background Technology

[0002] In the field of geological disaster prevention and control in mountainous areas, high-altitude material sources, such as rock masses or landslide soil instability, can trigger a chain of disasters that are destructive. As they slide down the mountain slope at high speed, they can not only directly impact the areas below, but also trigger secondary collapses, mudslides and other chain disasters, threatening the lives and property of residents along the route and transportation arteries.

[0003] Currently, most existing high-altitude material source control devices adopt a single interception structure or a single diversion structure. Although rigid interception structures have strong load-bearing capacity, they have weak buffering and energy dissipation capabilities for high-speed moving material sources. They are prone to structural damage due to excessive instantaneous impact force, leading to interception failure. After ordinary flexible nets intercept, the material source is prone to accumulate in the net body, forming a secondary load, and cannot effectively guide the trajectory of the material source. Some material sources may flow around to the protection blind zone. On the other hand, single diversion structures lack a pre-interception link and cannot achieve effective control when facing large-volume, high-kinetic-energy high-altitude material sources. Utility Model Content

[0004] In view of the technical problems existing in the background art, this application provides a high-level material source consolidation structure for geological disaster chains, including an interception section and a diversion section arranged sequentially from top to bottom along the mountain slope, wherein: The interception section includes anchor rods fixed to the mountain slope, and a ring net is connected between the anchor rods; The guiding section includes a guiding channel; There is a height difference between the ring net and the drainage channel, and the projection of the ring net in the height direction coincides with the drainage channel; Energy dissipation blocks are provided at intervals between the ring net and the drainage channel.

[0005] In some embodiments, the impact-facing side of the stilling pier is provided with an inclined surface, the inclined surface being inclined in the direction of the slope.

[0006] In some embodiments, the inclined surface is also inclined in the direction of the center of the drainage channel.

[0007] In some embodiments, the inclined surface is also provided with water-blocking protrusions.

[0008] In some embodiments, the stress-relief piers and the anchor bolts are arranged alternately in the vertical direction.

[0009] In some embodiments, the cross-sectional shape of the drainage channel is high on both sides and low in the middle.

[0010] In some embodiments, anti-collision barriers are provided at intervals within the drainage channel.

[0011] In some embodiments, the bottom of the ring net is connected to the drainage channel by a connecting rope.

[0012] In some embodiments, the bottom of the ring net is connected to the stilling pier by a connecting rope.

[0013] In some embodiments, a stabilizing portion is further included, which is connected to the lower part of the drainage channel, including: A group of steel columns is arranged inside the rock mass at the foot of the mountain slope; A steel plate pad, spherically hinged to the top of the steel column group; The slope reinforcement layer covers the slope toe and is partially welded to the steel plate pad to form an integral load-bearing surface layer, which evenly transfers the slope toe load to the steel column group.

[0014] This application provides a high-level sediment source stabilization structure for geological disaster chains, comprising an interception section and a diversion section arranged sequentially from top to bottom along the mountain slope, wherein: The interception section includes anchor bolts fixed to the mountain slope, with a ring net connecting the anchor bolts; The drainage section includes drainage channels; There is a height difference between the ring net and the drainage channel, and the projection of the ring net in the height direction coincides with the drainage channel; Energy dissipation blocks are installed at intervals between the ring net and the drainage channel.

[0015] This application establishes an interception section and a diversion section sequentially along the mountain slope from top to bottom, creating a height difference between the ring net and the diversion channel, with their height projections coinciding. This allows the material source to smoothly escape from the net and enter the channel, preventing the material source from clogging the interception net and causing it to be damaged by pressure. By setting energy dissipation piers at intervals between the ring net and the diversion channel, a synergistic effect of flexible and rigid energy dissipation is formed, avoiding the problem of insufficient performance of a single energy dissipation form.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] In the field of geological disaster prevention and control in mountainous areas, high-altitude material sources, such as rock masses or landslide soil instability, can trigger destructive disaster chains. As these materials slide down mountain slopes at high speed, they not only directly impact the areas below but can also trigger secondary collapses, debris flows, and other chain disasters, posing a serious threat to the lives and property of residents along the affected routes and to major transportation arteries. Currently, existing high-altitude material source control devices mostly employ single interception or single diversion structures. While rigid interception structures have strong load-bearing capacity, their ability to buffer and dissipate energy from high-speed moving materials is weak, making them prone to structural damage due to excessive instantaneous impact forces, leading to interception failure. After interception by ordinary flexible nets, the material source easily accumulates within the net, creating secondary loads, and the nets cannot effectively guide the material's trajectory; some materials may even flow around to blind spots in the protection zone. Single diversion structures lack pre-interception links and cannot effectively control large-volume, high-energy high-altitude material sources.

[0029] Reference Figure 1 and Figure 2 A high-level material source stabilization structure for geological disaster chains includes an interception section and a diversion section arranged sequentially from top to bottom along the mountain slope, wherein: The interception unit is the core functional module of the device responsible for intercepting high-altitude material sources. It is the first line of defense barrier set up from top to bottom along the mountain slope. Its main purpose is to block the high-altitude material source in the early stages of instability and sliding, preventing the material source from rushing directly to the area below at high speed. At the same time, it provides buffer space for subsequent energy dissipation and diversion, and initially disperses the impact force of the material source through its own structural characteristics.

[0030] In this embodiment, the interception unit includes anchor rods 1 fixed on the mountain slope and a ring net 2 connected between the anchor rods 1. The anchor rods 1 serve as the fixed foundation of the interception unit. Through the anchoring effect that penetrates deep into the mountain, the impact force of the material source borne by the ring net 2 is transmitted to the stable rock layer of the mountain, ensuring that the interception unit does not shift or overturn under strong impact, and providing a stable installation support for the ring net 2.

[0031] The ring net 2 is a ring-shaped structure with a certain degree of flexibility and toughness. It directly contacts the high-level material source that is sliding down. It absorbs part of the kinetic energy of the material source by its own flexible deformation. At the same time, the ring structure helps to gather the dispersed material source and prevent it from flowing around.

[0032] The diversion section is the part of the device that guides the material source. It is located below the interception section and is mainly used to receive the material source after it has been processed by the interception section and the energy dissipation structure. It guides the material source to a preset safe area or drainage channel to achieve orderly discharge of the material source and prevent the material source from accumulating in the protected area.

[0033] The dredging section includes a dredging channel 3, which extends along the mountain slope to provide a fixed movement channel for the material source. The dredging channel restricts the movement range of the material source and ensures that the material source can be smoothly guided to the target area.

[0034] There is a height difference between the ring net 2 and the drainage channel 3. The ring net 2, installed from top to bottom along the mountain slope, is higher than the drainage channel 3 below, resulting in a significant vertical height difference. The projection of the ring net 2 in the vertical direction coincides with the drainage channel 3. This means that, viewed from a vertically downward perspective, the shadow cast by the ring net 2 on the mountain slope or horizontal plane partially overlaps with the area of ​​the drainage channel 3 below. In other words, a portion of the coverage area of ​​the ring net 2, in its vertical projection, falls above the drainage channel 3, ensuring that materials intercepted and dislodged by the ring net 2 can directly enter the drainage channel 3 under gravity, preventing them from deviating from the control area and bypassing the drainage channel 3.

[0035] Energy dissipation piers 4 are spaced between the ring net 2 and the dredging channel 3. The installation space of the energy dissipation piers 4 is between the ring net 2 of the interception section and the dredging channel 3 of the dredging section. It is an intermediate structure connecting the two, receiving the material falling from the ring net 2 and transitioning the material entering the dredging channel 3. The energy dissipation piers 4 are arranged at a certain interval to form dispersed blocking nodes. A gap needs to be maintained between two adjacent energy dissipation piers 4 so that the falling material can fall into the dredging channel 3.

[0036] Under the influence of gravity or external factors, the high-level material source becomes unstable and slides down the mountain slope at high speed. The sliding material source first comes into contact with the interception section located above. The ring net 2 uses its own flexible deformation to initially intercept and buffer the material source, absorbing some of its kinetic energy. At the same time, it gathers the dispersed material source through its scouring effect, preventing it from scattering and flowing around. After being initially processed by the ring net 2, the material source falls out of the ring net 2 under the action of gravity. Due to the height difference between the ring net 2 and the drainage channel 3, the material source gains a certain amount of falling potential energy. The falling material source collides multiple times with the spaced-out stilling blocks 4. During the collision process, the kinetic energy of the material source is consumed, and its speed decreases. After being dissipated by the stilling blocks 4, the material source falls into the drainage channel 3 below at a lower speed. The drainage channel 3 guides the material source to the preset safe drainage channel or accumulation area through the channel body constraint, completing the entire process.

[0037] In existing technologies, the interception net and the drainage channel 3 are placed at the same height. This results in either the drainage channel 3 being too shallow, making it difficult for internal debris to escape from the gap between the interception net and the drainage channel 3, or the drainage channel 3 needs to be deepened, leading to a larger amount of debris and water accumulation within the drainage channel 3, which easily causes erosion of the inner wall of the drainage channel 3. This application creates a certain height difference between the ring net 2 and the drainage channel 3, and makes the protection range of the ring net 2 overlap with that of the drainage channel 3. This allows the debris caught by the ring net 2 to fall smoothly into the drainage channel 3 without getting stuck in the ring net 2. This avoids the situation where the ring net 2 is unable to discharge the trapped debris in time, causing the pressure to increase and eventually leading to damage.

[0038] On the other hand, this application also provides energy dissipation piers 4 at intervals between the ring net 2 and the diversion channel 3, so as to continue to dissipate the energy of the debris flow that is falling in a parabolic manner with kinetic energy during the falling process. On the one hand, it eliminates the gravitational potential energy brought about by the height difference and avoids the debris flow directly impacting the inner wall of the diversion channel 3; on the other hand, it dissipates the energy of the debris flow that has not been completely dissipated by the interception net, so as to form a synergistic energy dissipation form that combines flexible energy dissipation and rigid energy dissipation. Moreover, the initial kinetic energy carried by the debris flow can be flexibly absorbed before the flexible energy dissipation, so as to avoid the energy dissipation piers 4 directly bearing high kinetic energy and causing damage to the impact side.

[0039] This application provides a high-level sediment source stabilization structure for geological disaster chains, comprising an interception section and a diversion section arranged sequentially from top to bottom along the mountain slope, wherein: The interception section includes anchor bolts 1 fixed on the mountain slope, and a ring net 2 is connected between the anchor bolts 1; The drainage section includes a drainage channel 3; There is a height difference between the ring net 2 and the drainage channel 3, and the projection of the ring net 2 in the height direction coincides with the drainage channel 3; Energy dissipation blocks 4 are installed at intervals between the ring net 2 and the drainage channel 3.

[0040] This application sets up an interception section and a diversion section sequentially from top to bottom along the mountain slope, so that there is a height difference between the ring net 2 and the diversion channel 3 and the projection of their height directions coincides, so that the material source can smoothly leave the net and enter the channel, avoiding the material source from blocking the interception net and causing it to be damaged by pressure; by setting up energy dissipation piers 4 at intervals between the ring net 2 and the diversion channel 3, a synergistic effect of flexible energy dissipation and rigid energy dissipation is formed, avoiding the problem of insufficient performance of a single energy dissipation form.

[0041] In some implementations, refer to Figure 2 The stilling pier 4 is equipped with an inclined surface 5 on the impact side, with the inclined surface 5 tilting towards the slope. Specifically, the stilling pier 4, which directly bears the high-level material source, adopts an inclined structure that is not perpendicular to the slope, and the tilting direction points towards the mountain slope, that is, the side away from the slope is high and the side closer to the slope is low. Thus, when the material source slides down the slope, the inclined surface 5 can decompose the impact force, avoid hard contact that causes local stress concentration in the pier body, and extend the service life. At the same time, the inclined surface 5 faces the slope, so even if the material source bounces after impact, it can weaken the kinetic energy of the material source again by hitting the slope, and will not leave the protection range, ensuring that it can fall into the drainage channel 3.

[0042] In some implementations, refer to Figure 2 and Figure 3The inclined direction of the inclined surface 5 also points towards the center of the drainage channel 3. Specifically, the inclined surface 5 on the impact side of the stilling pier 4 does not face the slope in a single direction, but forms a double inclined shape that faces the slope and converges inward. It maintains the foundation inclination trend of the side away from the slope being high and the side closer to the slope being low, while also inclining towards the central axis of the drainage channel 3, so that the inclined surface 5 as a whole presents an angle design that converges into the drainage channel 3. In this way, when the material source slides down the slope and impacts the inclined surface 5, the inclined surface 5 can not only decompose the impact force and avoid hard contact that causes local stress concentration in the pier, but also apply a guiding force to the material source pointing towards the center of the drainage channel 3 at the centripetal tilt angle, allowing the material source to move naturally towards the middle of the drainage channel 3, reducing the risk of the material source deviating from the side walls of the drainage channel 3 and causing erosion to the channel walls; at the same time, even if the material source rebounds after impact, the centripetal tilt surface 5 will limit the rebound direction, preventing the material source from deviating out of the channel, but instead bringing it towards the center of the channel. If it contacts the slope during the rebound, it can further weaken the kinetic energy of the material source, ultimately ensuring that the material source falls into the drainage channel 3, further reducing the risk of bypassing the flow.

[0043] In some implementations, refer to Figure 2 Furthermore, water-blocking protrusions 6 are also provided on the inclined surface 5. Specifically, on the surface of the inclined surface 5 on the impact side of the stilling pier 4, strip-shaped protrusions are arranged at intervals to form water-blocking protrusions 6. For example, the direction of the water-blocking protrusions 6 is parallel to the slope direction; for example, the direction of the water-blocking protrusions 6 has an angle with the slope. When a debris flow or a water-bearing landslide carrying a large amount of water impacts the inclined surface 5 along the slope, the water-blocking protrusions 6 can directly block the water flow flowing down the slope, cutting the continuous water flow into small streams to weaken the hydrodynamic force. At the same time, when solid material impacts, it will generate additional collisions and friction with the protrusions, further decomposing the impact kinetic energy. Moreover, the uneven surface formed by the protrusions can increase the contact resistance between the material source and the inclined surface 5, slowing down the sliding speed. Thus, based on the energy dissipation of the inclined surface 5, the water-blocking protrusions 6 further improve the total energy dissipation rate by cutting and blocking the water flow and increasing friction resistance, allowing the material source to enter the drainage channel 3 at a lower speed, reducing the impact on the anti-scour threshold 7 of the drainage channel 3.

[0044] In some implementations, refer to Figure 2 and Figure 3 The stilling blocks 4 and anchor bolts 1 are arranged alternately in the vertical direction. Specifically, along the vertical direction of the mountain slope, the anchor bolts 1 that fix the ring net 2 of the interception section and the stilling blocks 4 that receive the impact of the material source are installed in a staggered manner without overlapping. This arrangement can avoid the force of the anchor bolts 1 and the stilling blocks 4 being concentrated on the same vertical rock layer. After they are staggered, the tensile force and compressive force act on the rock layers at different heights, which can distribute the load to a wider range of mountain stability areas and prevent a single rock layer from fracturing due to concentrated force.

[0045] In some implementations, refer to Figure 3The cross-sectional shape of the drainage channel 3 is high on both sides and low in the middle. Specifically, the cross-section of the drainage channel 3 is V-shaped or has a U-shaped concave structure with a certain inclination angle on both sides and a short flat bottom in the middle. This cross-sectional design can, on the one hand, guide the material source to converge naturally by utilizing gravity: when the material source enters the drainage channel 3 after being dissipated by the stilling pier 4, it will gather towards the center of the bottom of the channel due to the low concave structure in the middle, preventing the material source from being dispersed to the vicinity of the side walls and reducing direct scouring of the channel walls; on the other hand, the high side walls of the channel can form a physical barrier, especially when facing high-concentration debris flows, it can prevent the fluid carrying a large number of solid particles from overflowing from the channel, preventing the material source from spreading outside the protection range and causing secondary disasters. At the same time, the material source concentrated in the middle can also form a gravity flow effect, improving the drainage efficiency and preventing the material source from accumulating and blocking the channel locally; in some embodiments, the bottom of the drainage channel 3 is provided with a wear-resistant layer, which specifically concentrates the wear of the material source on the channel body in the middle bearing area and focuses on maintenance, reducing the overall maintenance cost and extending the service life of the drainage channel 3.

[0046] In some implementations, refer to Figure 3 Anti-scouring barriers 7 are installed at intervals inside the drainage channel 3. Specifically, protruding anti-scouring barriers 7 are arranged at fixed intervals inside the drainage channel 3 along the extension direction of the channel body, that is, the direction of material flow. When the material source, that is, the mudflow or rolling stones containing water, after being treated by the stilling dam 4, flows in the drainage channel 3, it will be blocked by the interval anti-scouring barriers 7, and the flow velocity will be forced to decrease.

[0047] In some implementations, refer to Figure 3 The bottom of the ring net 2 is connected to the drainage channel 3 via connecting rope 8. Specifically, when the ring net 2 intercepts high-energy material sources, it is prone to outward deformation due to impact. The deformation range needs to be controlled by the additional connecting rope 8. This is to prevent the projection of the ring net 2 from deviating from the overlap with the drainage channel 3 due to deformation under force, and also to prevent the falling range of rocks or landslide soil caught by the ring net 2 from exceeding the bearing range of the stilling pier 4, thus ensuring the coordination between the flexible and rigid stilling structures.

[0048] In some implementations, refer to Figure 4 The bottom of the ring net 2 is connected to the stilling pier 4 via a connecting rope 8. Specifically, the stilling pier 4 is closer to the bottom of the ring net 2, resulting in a shorter force path and allowing for better control of the deformation of the ring net 2 via the connecting rope 8.

[0049] In some implementations, refer to Figure 1 and Figure 5 It also includes a stabilizing part, which is connected to the lower part of the drainage channel 3, including: The steel column group 90 is arranged inside the rock mass at the foot of the mountain slope; Steel plate pad 91, ball joint at the top of steel column group 90; The slope reinforcement layer 92 covers the slope toe and is partially welded to the steel plate pad 91 to form an integral load-bearing surface layer, which evenly transfers the slope toe load to the steel column group 90.

[0050] Specifically, the stabilizing section is the core structure that bears the load of the drainage channel 3 and prevents the slope toe from becoming unstable. The steel column group 90 uses hot-dip galvanized steel columns embedded in the deep stable rock mass at the foot of the mountain in a quincunx pattern, so that the steel columns are tightly combined with the rock mass to form a pull-out and shear-resistant foundation. The steel plate pad 91 is connected to the top of the steel column through a ball joint to avoid stress caused by installation errors between the steel column and the reinforcement layer. The slope reinforcement layer 92 is a two-way steel mesh that covers the slope toe and the slope surface. Its edge is welded to the steel plate pad 91 to form a continuous load-bearing surface layer.

[0051] When the drainage channel 3 receives the material source, it will generate vertical pressure and lateral thrust. These loads are first transferred to the slope reinforcement layer 92 covering the slope toe. Since the reinforcement layer is an integral steel mesh structure, it can transform the local concentrated load into a uniformly distributed surface load. Subsequently, the uniform load is transferred to the steel plate pad 91 through the welded joint. The ball joint can adapt to the small angular deviation between the steel column group 90 and the reinforcement layer, avoiding local stress concentration caused by rigid connection. Finally, the load is transferred from the steel plate pad 91 to the steel column group 90. The steel column group 90 penetrates into the deep rock mass, dispersing the load to the stable rock layer. At the same time, the pull-out force and shear force of the steel columns are used to counteract the sliding tendency of the slope toe caused by the load, preventing the slope toe soil from becoming unstable.
