Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster protection, and in particular to a debris flow protection device for geological disaster prevention. Background Art

[0002] A debris flow is a special torrent of water caused by precipitation (heavy rain, glaciers, melted snow) in valleys or hillsides, carrying a large amount of solid materials such as mud, stones and boulders. Debris flows are characterized by suddenness, fast flow rate, large flow rate, large material capacity and strong destructive power. Debris flows often destroy transportation facilities such as roads and railways and even villages and towns, causing huge losses. Therefore, protective projects are usually required in areas prone to debris flows to resist or eliminate the damage of debris flows to main buildings.

[0003] The prior art (application number 202320189992.1) discloses a debris flow protection device for preventing geological disasters. When the debris flow contacts the retaining plate, the retaining plate slides in the chute away from the debris flow under the impact of the debris flow. The retaining plate drives the length of the telescopic rod to shorten, thereby causing the damping spring to contract and partially absorb the impact force of the debris flow, thereby preventing the retaining plate from directly docking with the debris flow, effectively improving the problem that the existing debris flow protection project is easily damaged when it contacts the debris flow, thereby reducing the protection effect against the debris flow.

[0004] That is, for debris flow protection devices for geological disaster prevention, the research direction is usually how to improve the impact resistance of the device so as to play a corresponding protective function. However, for debris flow, it is usually accompanied by a large amount of debris rushing down. After the debris flow protection device resists its impact force, due to too much debris flow, overflow will occur and continue to impact downward. Therefore, during the debris flow protection process, although it can rely on strength to resist, the subsequent protection effect is low, and in unexpected situations, it is not easy to play a better protective role for people and property. Therefore, the present invention proposes a debris flow protection device for geological disaster prevention to solve the problems existing in the prior art. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide a debris flow protection device for preventing geological disasters. The debris flow protection device for preventing geological disasters has the advantages of good protection effect and can solve the problems existing in the prior art.

[0006] To achieve the purpose of the present invention, the present invention is implemented through the following technical solutions: a debris flow protection device for geological disaster prevention, including a protective top plate, a support column is installed below the protective top plate, and the support column is provided with several groups, a protective seat is installed on the side of the protective top plate away from the support column, and the left and right sides of the protective seat are both arranged in an arc shape, the protective top plate consists of a protective section, a connecting section and a load-bearing section, the protective section is connected to the load-bearing section through the connecting section, and both ends of the connecting section are arranged perpendicular to the protective section and the load-bearing section, a protective assembly is installed below the protective section, a buffer assembly is installed above the load-bearing section, and a force unloading assembly is installed on the inner side of the protective seat.

[0007] A further improvement is that a first cavity is provided on the inner side of the protective seat, the force unloading assembly includes an inner mounting seat, an inner elastic plate is installed on the inner mounting seat, the inner elastic plate is vertically arranged, and a rubber layer is filled on one side of the first cavity close to the support column, and one side of the rubber layer is in contact with the inner elastic plate.

[0008] A further improvement is that the buffer assembly includes an outer elastic plate, one end of which is connected to the load-bearing section, a spring telescopic member is installed below the other end of the outer elastic plate, and the spring telescopic member is provided in several groups, the spring telescopic member is connected to the load-bearing section, and the outer elastic plate is arranged in an arc shape.

[0009] A further improvement is that the protection component includes a wire interception net, the wire interception net is provided with a plurality of groups, and the plurality of groups of wire interception nets are arranged in sequence from top to bottom, and the two ends of the wire interception net are respectively fixedly connected to the support column and the connecting section.

[0010] A further improvement is that a fixing ring is installed on the support column, an arc-shaped supporting plate is provided between the fixing ring and the connecting section, and two ends of the arc-shaped supporting plate are fixedly connected to the fixing ring and the connecting section respectively.

[0014] The beneficial effects of the present invention are as follows: the present invention helps to effectively disperse the impact force through the improved design of the protective top plate, and guides the debris flow to the outside of the road, thereby expanding the protection area and avoiding the direct impact of the debris flow. The protection seat is then used to enhance the stability and impact resistance of the present invention. When the impact force of the debris flow acts on the protective seat, the protective seat can disperse and slow down the energy of the debris flow through a reasonable layout and cavity design, thereby ensuring that even if a large-scale overflow occurs, the protective device can still provide sufficient protection. Therefore, when facing unexpected situations, the present invention can protect a wider range, thereby better protecting people and property. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0021] At present, debris flow protection projects usually adopt the method of installing retaining boards to block and protect against debris flows. The retaining boards are installed at the foot of the slope in areas prone to debris flows, and a supporting structure is installed on the back of the retaining boards. When debris flows occur, the debris flows are blocked outside roads, railways, villages and towns.

[0022] Since debris flows usually originate from valleys or hillsides, when they flow from valleys or hillsides to the foot of the slope, due to the height difference, the debris flows usually carry a large impact force. When the debris flow protection device resists the pressure, overflow may occur, that is, there may still be debris flows overflowing from outside the protection range of the debris flow protection device. For example, if it is laid on the road, it will still have a corresponding impact on the range behind the debris flow protection device. Therefore, in the event of an accident, when there are people or vehicles behind the protection device, the protection device cannot provide them with secondary protection.

[0023] Therefore, according to Figure 1-Figure 4 As shown, this embodiment proposes a debris flow protection device for geological disaster prevention, including a protective top plate, which is composed of a protective section 3, a connecting section 4 and a load-bearing section 5. The protective section 3 is connected to the load-bearing section 5 through the connecting section 4, and both ends of the connecting section 4 are vertically arranged with the protective section 3 and the load-bearing section 5. In this embodiment, the structure of the protective top plate is designed accordingly. First, the protective section 3 is horizontally arranged, and its purpose is to provide a larger protection range. At the same time, the upper end of the protective section 3 is provided with an inclined structure, which can play a certain guiding role. The connecting section 4 corresponds to the connecting role, while the load-bearing section 5 plays a role in resisting pressure.

[0024] A support column 1 is installed below the protective top plate, and the support column 1 is provided with several groups. In this embodiment, two groups of support columns 1 are evenly provided. The number of support columns 1 increases according to the length of the protective top plate. A fixing seat 18 is installed at the lower end of the support column 1, and the lower end surface of the fixing seat 18 is flush with the lower end surface of the protective seat 2. Figure 4 As shown, the device is suitable for road debris flow protection operations. The support column 1 and the protection seat 2 are located on both sides of the road, and vehicles and people walk under the protection section 3. Specifically, when it is laid out, the lower ends of the fixed seat 18 and the protection seat 2 are located below the ground, that is, they are pre-buried in the ground. At this time, the lower end surface of the support column 1 is in a flush state with the ground to increase the contact area between the device and the ground and enhance stability.

[0025] A protective seat 2 is installed on the side of the protective top plate away from the support column 1, and the left and right sides of the protective seat 2 are both arranged in an arc shape, that is, Figure 1 As shown, the arc-shaped setting on the right is used to fit the slope beside the road. When a debris flow occurs, it serves as the first contact surface and plays the first layer of protection. The arc-shaped setting on the left faces the right side of the protective seat 2 and plays the second layer of protection. When the right side of the protective seat 2 is damaged, its left side plays a subsequent supporting and protective role.

[0026] Furthermore, a force unloading assembly is installed on the inner side of the protective seat 2, and a first cavity 6 is provided on the inner side of the protective seat 2. When the outer side of the protective seat 2 is hit by a debris flow, the cavity part can effectively absorb and disperse a part of the energy, reducing the energy transferred to the other side of the protective seat 2, that is, reducing the impact on the other side of the protective seat 2. When one side of the protective seat 2 is broken or damaged, the existence of the hollow part allows a certain physical isolation between the damaged area and the other side. This can prevent the external impact force from directly acting on the other side, and at the same time, it also prevents the stress in the damaged area from directly affecting the undamaged area, reducing the collapse or damage of the overall structure. Therefore, the hollow part acts as a buffer layer to reduce the direct destructive force on the other side.

[0027] Correspondingly, the force unloading component includes an inner mounting seat 7, on which an inner elastic plate 8 is installed. The inner elastic plate 8 is vertically arranged, and its upper end is close to the top of the first cavity 6. The side of the first cavity 6 close to the support column 1 is filled with a rubber layer 9, and one side of the rubber layer 9 is in contact with the inner elastic plate 8. When the protective force of the right side of the protective seat 2 fails, part of the debris flow continues to impact the inner side of the protective seat 2. During the whole process, the deformation of the inner elastic plate 8 and the rubber layer 9 is used to buffer the force on the left side of the protective seat 2. At the same time, a third cavity is provided on the inner side of the protective seat 2, and the inner side of the third cavity is filled with a reinforcing plate 17. The position of the reinforcing plate 17 corresponds to the left side of the protective seat 2 to enhance its strength. This is linked together to enhance the protective effect on the slope.

[0028] Furthermore, the inner side of the protective seat 2 is provided with a second cavity 15, and the second cavity 15 is arranged in an arc shape. The protective seat 2 is provided with a through hole 16, and the through hole 16 is provided with several groups. The through hole 16 is connected with the second cavity 15. The function of the second cavity 15 is consistent with that of the first cavity 6, but the difference is that the second cavity 16 is in contact with the slope surface, and the through hole 16 is also provided. A protective net is installed on the inner side of the through hole 16. Therefore, when the protective seat 2 meets the impact of the debris flow, part of it will pass through the through hole 16 and enter the second cavity 16. In this process, a partial filling effect will be produced on it. Therefore, the accumulation of the filler and the space of the cavity will have a certain suppressing effect on the flow of the debris flow, reducing the energy of the debris flow, thereby reducing the impact force on the protective seat 2. At the same time, as the mud and rock fill the cavity, the filler itself can absorb part of the kinetic energy and reduce its impact on the protective structure. This energy conversion helps to disperse and reduce the intensity of the impact, and prevent the protective seat 2 from being damaged when encountering a large-scale debris flow.

[0029] A buffer component is installed above the load-bearing section 5. When the protective seat 2 plays its protective role, the debris flow is still falling continuously, so it will produce an accumulation effect, resulting in subsequent overflow. In this process, the buffer component is set to protect and buffer the connecting section 4. Specifically, the buffer component includes an outer elastic plate 10, one end of the outer elastic plate 10 is connected to the load-bearing section 5, and a spring telescopic member 11 is installed below the other end of the outer elastic plate 10, and the spring telescopic member 11 is provided with several groups. The spring telescopic member 11 is connected to the load-bearing section 5, and the outer elastic plate 10 is arranged in an arc shape. Accordingly, elasticity is used to play a buffering role. At the same time, the setting of the outer elastic plate 10 enables the overflowing debris flow to pass better from above the protective section 3, and there is no blocking component above the protective section 3, so the impact force of the debris flow will not completely act on the protective seat 2.

[0030] A protective component is installed below the protective section 3, and the protective component includes a wire interception net 12. The wire interception net 12 is provided in several groups. In the present embodiment, there are two groups of wire interception nets 12, and the two groups of wire interception nets 12 are arranged in sequence from top to bottom. The two ends of the wire interception net 12 are respectively fixedly connected to the support column 1 and the connecting section 4. A fixing ring 13 is installed on the support column 1. An arc-shaped support plate 14 is provided between the fixing ring 13 and the connecting section 4. The two ends of the arc-shaped support plate 14 are respectively fixedly connected to the fixing ring 13 and the connecting section 4. The function of the protective section 3 is to protect vehicles and pedestrians passing below it, that is, when an unexpected situation occurs and a person or a vehicle is within the protection range of the device, the device plays the important task of protecting the personal and property safety. Therefore, a protective component is arranged below the protective section 3. First of all, the wire interception net 12 can play an intercepting role. When the protection section 3 is understressed or broken, the wire interception net 12 can prevent the falling mud and rocks from directly colliding with the arc support plate 14, and the arc support plate 14 plays a further protective role. Therefore, the present invention can provide better protection for people and vehicles passing below it in unexpected situations, and then can provide better protection for people and property.
