Description

Technical Field

[0001] This utility model relates to the field of natural disaster prevention technology, specifically a high-frequency debris flow bank protection and diversion structure. Background Technology

[0002] While railways and highways are becoming more widespread in mountainous areas, the areas they cross often have complex geological and topographical conditions, fragile environments, and frequent debris flow disasters. Debris flow disasters can easily cause huge damage to riverbanks, highways, and infrastructure along the route, as well as a series of economic losses. Therefore, diversion channels are usually set up to guide the direction of debris flows in order to minimize the damage to the surrounding basic environment.

[0003] Currently available diversion channels can only control the flow velocity by controlling the direction of debris flows. However, debris flows carry a large amount of solids such as mud, sand, rocks, and trees, and still have a large impact force during the impact process, which can easily cause damage to the embankment. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a high-frequency debris flow bank protection and diversion structure to solve the technical problem that although existing diversion channels can control the direction of debris flow, they cannot effectively buffer its impact force, resulting in the bank being easily damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-frequency debris flow revetment and diversion structure, comprising soil and rocks and protective components, wherein the protective components include a first protective mechanism and a second protective mechanism, the first protective mechanism includes a fixed column, and two first steel cables are fixedly connected to the upper and lower ends of the fixed column, and a first barrier net is welded onto the first steel cables.

[0006] By adopting the above technical solution, the two first steel cables are fixedly connected through the upper and lower ends of the fixed column, providing solid support for the first barrier net. The first steel cables have high strength and toughness and can withstand the huge tensile force generated by the impact of debris flow.

[0007] Furthermore, the second protective mechanism includes a second barrier net, on both sides of which are welded second steel cables, and fixed anchors are provided at both ends of the second steel cables.

[0008] By adopting the above technical solution, the second steel cable is welded to both sides of the second barrier net, providing additional support and fixation for the barrier net. Under the powerful impact of the debris flow, the strength of the barrier net itself may not be enough to withstand it, while the presence of the steel cable can enhance the overall stability of the barrier net.

[0009] Furthermore, the second steel cable is provided in two groups, and each group has several second steel cables arranged in a linear array at equal intervals.

[0010] By adopting the above technical solution, two sets of second steel cables are set up, and each set is arranged in a linear array with several cables evenly spaced. This layout enhances the overall tensile strength of the second protective mechanism. When the debris flow impacts the second barrier with a strong impact force, the two sets of second steel cables can jointly bear the tension and distribute the force evenly to each steel cable.

[0011] Furthermore, both the first and second barrier nets are composed of several metal rings, and several protective components are provided on the inclined surface of the soil and rock.

[0012] By adopting the above technical solution, the metal rings have high strength and toughness, and the first and second barrier nets composed of several metal rings can withstand greater impact forces.

[0013] Furthermore, a retaining groove is provided between the first and second barrier nets, and the cross-section of the retaining groove is trapezoidal.

[0014] By adopting the above technical solution, the cross-section of the retaining channel is set in a trapezoidal shape. This unique shape provides favorable conditions for the deposition of silt and solid materials, effectively reducing the content of solid materials in debris flows.

[0015] Furthermore, a deceleration groove is provided on the top of the soil and rock, and side walls are provided on both sides of the slope of the soil and rock.

[0016] By adopting the above technical solution, when the debris flow rushes down from above at high speed, it will first come into contact with the arc surface of the deceleration trough. The shape of the arc surface changes the flow direction of the debris flow, causing its flow trajectory to deflect. At the same time, due to the resistance of the arc surface, the impact velocity of the debris flow is effectively reduced.

[0017] In summary, the present invention has the following main advantages:

[0018] This utility model, by setting up protective components, has a first barrier net in the first protective mechanism that can initially intercept larger solid materials such as boulders and tree trunks in debris flows, and a second barrier net in the second protective mechanism that further intercepts mud and sand and remaining solid materials, reducing the direct impact of solid materials in debris flows on the bank, effectively buffering the impact force, and preventing the bank from being damaged by huge impacts. Both the first and second barrier nets are composed of several metal rings. This structure ensures the strength of the barrier nets while giving them a certain degree of flexibility. Under the impact of debris flows, the barrier nets can bend to a certain extent, improving the adaptability and reliability of the protective components.

[0019] This invention incorporates a deceleration trough and a baffle trough. The baffle trough is positioned between the first and second barrier nets. Its trapezoidal cross-section provides favorable conditions for the deposition of mud, sand, and solid materials. When a debris flow passes through the first barrier net, the larger solid materials it carries are blocked, while the mud, sand, and some smaller solid materials continue to flow into the baffle trough. In the baffle trough, due to the further reduction in water flow velocity and the blocking effect of the trough's shape, when the debris flow surges down with enormous energy, it first impacts the deceleration trough. Due to the special shape of the deceleration trough's arc surface, the flow direction of the debris flow changes, and its impact velocity is effectively reduced. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] A high-frequency debris flow bank protection and diversion structure, such as Figures 1-4As shown, the structure includes soil and rock 1 and protective components 7. The protective components 7 include a first protective mechanism 2 and a second protective mechanism 5. The first protective mechanism 2 includes a fixed column 201. Two first steel cables 203 are fixedly connected to the upper and lower ends of the fixed column 201. A first barrier net 202 is welded to the first steel cables 203. The two first steel cables 203 are fixedly connected through the upper and lower ends of the fixed column 201, providing solid support for the first barrier net 202. The first steel cables 203 have high strength and toughness and can withstand the huge tensile force generated when the debris flow impacts. The fixed column 201 serves as the basic support structure of the first protective mechanism 2 and is fixed in the soil and rock 1, providing a reliable fixing point for the first steel cables 203 and the first barrier net 202.

[0027] See Figure 3 The second protective mechanism 5 includes a second barrier net 501. Second steel cables 502 are welded to both sides of the second barrier net 501. Fixed anchors 503 are set at both ends of the second steel cables 502. The second steel cables 502 are welded to both sides of the second barrier net 501, providing additional support and fixation for the barrier net. Under the strong impact of the debris flow, the strength of the barrier net itself may be insufficient to withstand the force, while the presence of steel cables can enhance the overall stability of the barrier net. The fixed anchors 503 are set at both ends of the second steel cables 502, firmly fixing the entire second protective mechanism 5 to the side wall 4.

[0028] See Figure 3 The second steel cable 502 is provided in two sets, and each set of the second steel cable 502 is arranged in a linear array with several cables evenly spaced. This layout enhances the overall tensile strength of the second protective mechanism. When the debris flow impacts the second barrier 501 with a strong impact force, the two sets of second steel cables 502 can jointly bear the tension and distribute the force evenly to each steel cable. The linear array arrangement with even spacing allows the second steel cable 502 to distribute the pressure more evenly when under stress.

[0029] See Figure 1 , Figure 2 , Figure 3 The first barrier 202 and the second barrier 501 are both composed of several metal rings. Several protective components 7 are set on the slope of the soil and rock 1. The metal rings have high strength and toughness. The first barrier 202 and the second barrier 501, composed of several metal rings, can withstand a large impact force. Multiple protective components 7 form a multi-layer protective barrier on the slope of the soil and rock 1, which can prevent the debris flow from directly scouring and eroding the slope of the soil and rock.

[0030] See Figure 1 , Figure 4A retaining groove 3 is provided between the first barrier 202 and the second barrier 501. The cross-section of the retaining groove 3 is trapezoidal. This unique shape provides favorable conditions for the deposition of mud, sand and solid materials, effectively reducing the content of solid materials in the debris flow. When the first barrier 202 intercepts a large amount of solid materials, it will bear huge impact pressure. At this time, the retaining groove 3, as a buffer area between the first protective mechanism 2 and the second protective mechanism 5, can effectively share the pressure borne by the first barrier 202.

[0031] See Figure 1 , Figure 4 A deceleration groove 6 is provided on the top of the soil and rock 1, and side walls 4 are provided on both sides of the slope of the soil and rock 1. When the debris flow rushes down from above at high speed, it will first come into contact with the arc surface of the deceleration groove 6. The shape of the arc surface changes the flow direction of the debris flow, causing its flow trajectory to deflect. At the same time, due to the resistance of the arc surface, the impact speed of the debris flow is effectively reduced. During the flow of the debris flow, due to the blocking effect of the side walls 4, the debris flow can flow along the predetermined direction, ensuring that the debris flow can smoothly enter the protection area covered by the first protection mechanism 2 and the second protection mechanism 5.

[0032] The implementation principle of this utility model is as follows: When a debris flow impacts, it first passes through the deceleration groove 6. The arc surface of the deceleration groove 6 can effectively reduce the impact speed of the debris flow. Then, the debris flow passes through the first barrier net 202. The first barrier net 202 intercepts solids such as rolling stones and tree trunks in the debris flow. At the same time, the water flows into the baffle groove 3 through the gap of the metal ring to slow down. When the first barrier net 202 intercepts a large number of solids or bears a large impact, the first steel cable 203 drives the first barrier net 202 to bend towards the baffle groove 3, so that the solids in the first barrier net 202 gradually fall into the baffle groove 3, releasing the pressure of the first barrier net 202. Then, the baffle groove 3 causes the mud and solids in the debris flow to settle. At the same time, the water flows out from the second barrier net 501. When the amount of mud and solids in the baffle groove 3 is large, it presses the second barrier net 501, causing the second barrier net 501 to drive the second steel cable 502 to bend away from the baffle groove 3, so that the mud and solids gradually flow from below the second barrier net 501 to the subsequent multi-stage protection components 7.
