Embodiment 1

[0038] refer to Figure 1 to Figure 6 , a debris flow drainage structure of the present invention, comprising:

[0039] mountain 1;

[0040] The blocking mechanism 2 is arranged on the slope of the mountain and is used to block the downstream of the debris flow;

[0041]The flow diversion mechanism 3 is arranged at the bottom of the mountain and connected with the flow blocking mechanism, and is used for horizontally diverting the debris flow that slides down from the flow blocking mechanism; the flow blocking mechanism 2 includes at least two side walls 201 perpendicular to the mountain body, and the side walls 201 It is anchored on the mountain body 1; a number of concave energy dissipation grooves 202 are horizontally arranged between adjacent side walls; gravel 203 is laid on the bottom of the energy dissipation groove. The invention blocks the mud-rock flow through the flow blocking mechanism, reduces the potential energy of the mud-rock flow sliding down, and achieves ...

Embodiment 2

[0044] refer to image 3 with Figure 5 , on the basis of Embodiment 1, this embodiment is provided with several blocking piles 204 between adjacent energy dissipation grooves, and the ends of the blocking piles are provided with bases 205; the bases are buried in the mountain body, and the blocking piles protrude from the surface of the mountain body; adjacent blocking piles are connected by cross bars 206 . The blocking piles block the debris flow passing through and slow down the sliding speed of the debris flow; in addition, the crossbar connects the blocking piles in the same horizontal row, which enhances the overall strength of the blocking piles and improves the overall stability of the blocking piles and firmness, so as to ensure the retarding effect of the retarding pile on the debris flow.

[0045] refer to Figure 5 , the base 205 of this embodiment is tapered, and the base gradually increases in the direction away from the blocking pile; the base is provided wi...

Embodiment 3

[0047] refer to figure 1 , figure 2 with image 3 , on the basis of Embodiment 1, this embodiment is provided with a blocking frame 208 inclined on the side of the flow blocking mechanism close to the flow guiding mechanism, and the blocking frame is clamped between two adjacent side walls; the blocking frame An intercepting net 209 is arranged on the 208 . The blocking frame plays a blocking role on the debris flow passing through, reduces the potential energy of the debris flow sliding down, and reduces the speed of the debris flow sliding; in summary, it can be seen that the present invention uses three measures to block the debris flow, which are respectively energy dissipation tank, Blocking piles and blocking frames, under the triple measures, can better block the debris flow, minimize the potential energy and speed of the debris flow, and prevent the debris flow from causing devastating damage to the building facilities or engineering facilities below the mountain. ...

Abstract

The invention discloses a debris flow drainage and guide structure. The debris flow drainage and guide structure comprises a mountain body, a flow blocking mechanism arranged on the slope of the mountain body and a flow guide mechanism arranged at the bottom of the mountain body, wherein the flow blocking mechanism comprises at least two side walls perpendicular to the mountain body, and the sidewalls are anchored to the mountain body; and a plurality of inwards-concave energy dissipation grooves are transversely formed between the adjacent side walls. According to the debris flow drainage and guide structure, debris flow is blocked through the flow blocking mechanism, so that the potential energy of the sliding down of the debris flow is reduced, and the purpose of reducing the flow speed of the debris flow is achieved; then the debris flow sliding down from the flow blocking mechanism is guided to the designated positions on the two horizontal sides through the flow guide mechanism,and thus the destructive damage of the debris flow to building facilities or engineering facilities below the mountain body is avoided; and the energy dissipation grooves, blocking piles and blockingframes are adopted, the debris flow is better blocked under the triple measures, the potential energy and speed of the sliding down of the debris flow are reduced to the maximum extent, and the destructive damage of the debris flow to the building facilities and the engineering facilities below the mountain body is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a debris flow drainage structure. Background technique [0002] Debris flow refers to a special torrent carrying a large amount of sediment and stones due to landslides caused by heavy rain, snowstorm or other natural disasters in mountainous areas or other areas with deep valleys and steep terrain. Debris flow has the characteristics of suddenness, fast flow rate, large flow rate, large material capacity and strong destructive force. Debris flows often destroy highways, railways and other transportation facilities and even villages and towns, causing huge losses. Debris flow drainage works are engineering facilities for preventing and controlling debris flows. Debris flow drainage projects are built in areas where debris flows often endanger nearby residential areas, industries, mines, and traffic. As one of the main types of debris flow prevention and control en...
