Embodiment 1

[0058] Embodiment 1: as Figure 1~14 As shown, a geological disaster prevention and control system for flood control and debris flow prevention includes a separation system, an energy dissipation system, a silting and dredging system, and an aqueduct 19,

[0059] The separation system includes 3 rock-blocking ditches 3 and water-blocking gates. The three rock-blocking ditches 3 are vertical to the water flow direction of the river channel 1 and arranged upstream of the river channel 1. The water-blocking gates include the prevention and control system water-blocking gate 2 and the river channel water-blocking gate 4. , the river water blocking gate 4 is set in the river channel 1 and downstream of the stone ditch 3, and the river channel water blocking gate 4 is perpendicular to the water flow direction in the river channel 1;

[0060] The energy dissipation system includes a deceleration chute 7, an anti-climbing baffle 10, an anti-shock baffle 11, a silt distribution channel...

Embodiment 2

[0069] Embodiment 2: The structure of the geological disaster prevention and control system for flood control and debris flow prevention in this embodiment is basically the same as the geological disaster prevention and control system for flood control and debris flow prevention in Embodiment 1. The speed reduction pile 8 is a triangular prism structure placed horizontally and one side of the triangular prism is fixedly arranged on the bottom surface of the speed reduction groove 7, and the section of the triangular prism is a right triangle, and the first right angle side of the right triangle is arranged on the bottom surface of the speed reduction groove 7, the second The two right-angled sides are arranged vertically upward on the front end of the first right-angled side, and the angle between the hypotenuse and the first right-angled side is 40°;

Abstract

The invention relates to a geological disaster prevention and control system and method for preventing flood and debris flow, and belongs to the technical field of geological disaster prevention and control. The geological disaster prevention and control system comprises a separation system, an energy dissipation system, a silt parking and desilting system and a diversion canal; the separation system comprises more than one stone retaining ditch and a water retaining gate; the energy dissipation system comprises a speed reduction slot, an anti-climbing baffle, an anti-impact baffle and a siltseparation passage; and the silt parking and desilting system comprises a silt parking place, a silt inlet, a flume, a silt discharge gate and a silt discharge passage. According to the invention, thebreakout characteristics and provenance properties of debris flow and flood are sufficiently considered; by arranging the separation system, the energy dissipation system, the silt parking and desilting system and the diversion canal, the debris flow is subjected to energy dissipation; if flow and an impact force of the debris flow or the flood are excessive, multiple stages of geological disaster prevention and control systems for preventing the flood and the debris flow can be arranged along the outside of a riverway or a cheuch so as to implement staged energy dissipation and decrement ofthe debris flow, carry out staged component control on the debris flow disaster and implement geological disaster prevention and control on the flood and the debris flow.

Description

technical field [0001] The invention relates to a geological disaster prevention and control system and method for flood control and debris flow prevention, and belongs to the technical field of geological disaster prevention and control. Background technique [0002] Debris flow refers to a special torrent that contains a large amount of sediment and stones and moves along slopes or valleys under the action of gravity, triggered by other water source conditions such as rainfall, ice and snow melting, or water body collapse. It is considered to be a mixture of earth, water, and air, and it often erupts in mountains or other areas with deep valleys and steep terrain. Debris flows have the characteristics of regularity, suddenness, and grouping. During the outbreak, the flow rate is fast, the flow rate is large, and the material capacity is large, and it is extremely destructive under the action of gravitational potential energy. Therefore, when mudslides occur, towns, mines,...
