Description

Technical Field

[0001] The utility model belongs to the technical field of debris flow protection, and in particular relates to a debris flow energy dissipation sill structure. Background Art

[0002] A debris flow refers to 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, sand, stones and boulders. In order to reduce the impact of the special torrent brought by the debris flow, energy dissipation barriers are installed in the corresponding river channels to block the solid materials such as mud, sand, stones and boulders transported by the debris flow. This is a very commonly used engineering measure in debris flow protection.

[0003] Chinese utility model patent CN220318475U discloses a debris flow energy dissipation sill structure, which includes an intercepting energy dissipation sill arranged along the width direction in the debris flow channel at the tail end of the debris flow accumulation area. The two sides of the energy dissipation sill are fixed to the debris flow channel, and an impact efficiency structure is provided to reduce the impact force generated by the debris flow when flowing in the channel, unloading the energy of the debris flow and ensuring the safety of buildings on both sides of the channel.

[0004] The above design can reduce the impact of debris flow through the cooperation of multiple sets of energy dissipation sills and impact energy dissipation structures. However, there are certain problems in actual use. Specifically, when the energy dissipation sill structure is used, it cannot block and filter solid materials such as mud, sand, and stones in the debris flow. A large amount of solid materials still flow with the debris flow, thereby reducing the overall safety and practicality of the energy dissipation sill. Utility Model Content

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Depend on Figure 1 and Figure 2As shown, it is a structural schematic diagram of the debris flow energy dissipation threshold structure in this embodiment, including multiple groups of energy dissipation components 2 installed in the debris flow slope protection 1, with diversion mechanisms 3 installed between the energy dissipation components 2, and diversion mechanisms 4 symmetrically installed on the inner wall of the debris flow slope protection 1. During use, the debris flow slope protection 1 is used to guide and transport the debris flow, so that the debris flow flows along the inner wall of the debris flow slope protection 1. When the debris flow moves to the target position, the energy dissipation component 2 is used to preliminarily screen the solid matter present in the debris flow, and then the debris flow passes through the energy dissipation component 2 and contacts the diversion mechanism 3. With the cooperation of the diversion mechanism 3 and the diversion mechanism 4, the impact force generated by the debris flow during flow is reduced, and the solid matter in the debris flow is accumulated inside the debris flow slope protection 1 and between the energy dissipation components 2 due to its own weight. On the premise of reducing the impact of the debris flow, the solid matter in the debris flow is screened and collected.

[0029] By the attached Figure 3 As shown, it is a structural schematic diagram of the energy dissipation component 2 in this embodiment, and the energy dissipation component 2 includes an energy dissipation frame 21, a top plate 22 and a screening rod 23. The multiple groups of energy dissipation frames 21 are installed on the inner wall of the debris flow slope protection 1, and the top plate 22 is fixedly installed at the top opening of the energy dissipation frame 21. The screening rod 23 is arranged between the top plate 22 and the energy dissipation frame 21. During use, the debris flow flows along the inner wall of the debris flow slope protection 1. The debris flow will first contact the side wall of the energy dissipation frame 21. Under the action of the energy dissipation frame 21, the impact force of the debris flow is preliminarily blocked, and the screening rod 23 and the top plate 22 cooperate to limit the overall flow port of the energy dissipation frame 21 to prevent solid matter with too large a volume in the debris flow from passing through the energy dissipation frame 21 and flowing into subsequent components.

[0030] By the attached Figure 2 As shown, it is a structural diagram of the energy dissipation component 2 in this embodiment. The energy dissipation frame 21 is composed of two symmetrically arranged groups of connecting plates and a base plate. Connecting plates are symmetrically installed on both sides of the base plate. The connecting plates are installed on the inner wall of the debris flow slope protection 1. During use, the connecting plates are used to stably install the energy dissipation component 2 as a whole in the debris flow slope protection 1, and the bottom plate and the height of the bottom plate itself are coordinated to screen the solid matter in the debris flow layer by layer.

[0031] By the attached Figure 3As shown, it is a structural diagram of the energy dissipation component 2 in this embodiment. There are three groups of energy dissipation frames 21, and the bottom plates in the three groups of energy dissipation frames 21 are of different heights. The number of screening rods 23 installed gradually increases with the flow direction of the debris flow. During use, there are three groups of bottom plates, and the heights of the three groups of bottom plates are different. The bottom plate with the lowest height first contacts the debris flow and preliminarily weakens the impact force of the debris flow. The bottom plate at the middle end has a moderate height, which further weakens the impact of the debris flow while blocking some solid matter in the debris flow, allowing such solid matter to remain between the bottom plates. Finally, through the use of the bottom plate at the highest height, the debris flow that has been weakened twice is received. The solid matter in the debris flow will automatically settle to the bottom of the debris flow due to its own weight and the reduction of the debris flow velocity. At this time, the bottom plate at the highest height can block a large amount of solid matter in the debris flow and reduce the harm caused by the debris flow.

[0032] By the attached Figure 5 As shown, it is a structural schematic diagram of the diversion mechanism 3 in this embodiment, the diversion mechanism 3 includes a fixed seat 31, a support end 32 and a buffer end 33, the fixed seat 31 is installed in the debris flow slope protection 1, and the fixed seat 31 is arranged between the energy dissipation components 2, the support end 32 is fixedly installed on the side of the fixed seat 31, and the buffer end 33 is fixedly installed on the side of the support end 32, and the buffer end 33 is overall in an arc shape. When the debris flow initially passes through the first group of energy dissipation components 2 in use, a large amount of debris flow directly hits the side surface of the buffer end 33, and the shape and structure of the buffer end 33 itself are used to divert the debris flow as a whole, reducing the impact of the debris flow while the debris flow flows to both sides.

[0033] By the attached Figure 5 As shown, it is a structural diagram of the diversion mechanism 3 in this embodiment. Support steel frames are symmetrically installed at the ends of the fixed seat 31, and the support steel frames are connected to the debris flow slope protection 1. The position of the fixed seat 31 is further reinforced during use. When the buffer end 33 is subjected to a large amount of impact from the debris flow, the support steel frame can ensure the overall stability of the fixed seat 31 and prevent the diversion mechanism 3 as a whole from being broken under the impact of the debris flow.

[0034] By the attached Figure 6As shown, it is a structural schematic diagram of the guide mechanism 4 in this embodiment, the guide mechanism 4 includes a guide plate 41, a mounting plate 42 and a reinforcing rib 43, the guide plate 41 is symmetrically arranged on both sides of the inner wall of the debris flow slope protection 1, the reinforcing rib 43 is equidistantly fixedly installed on the side surface of the guide plate 41, the mounting plate 42 is fixedly installed on the side of the guide plate 41, and the mounting plate 42 is connected to the inner wall of the debris flow slope protection 1. When the buffer end 33 diverts the debris flow in use, the guide plate 41 can receive the diverted debris flow, and a large amount of debris flow contacts the surface of the guide plate 41. The guide plate 41 is in an arc shape as a whole, which can guide the diverted debris flow to merge under the premise of weakening the impact of the debris flow. During the merging process, the diverted debris flows impact each other, further reducing the impact force of the debris flow itself.

[0035] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
