Movable diversion device for debris flow interception
The invention relates to a movable diversion device for debris flow interception. The movable diversion device is arranged in a debris flow passage formed between highlands on two sides and comprisesa stopping and silting diversion dam and two movable flow guidance mechanisms. The stopping and silting diversion dam divides the debris flow into two streams and constructs multiple new stopping andsilting areas, so that the debris flow can slow down, settle down and partially stop. The movable flow guidance mechanisms can automatically judge whether partial interception is required according tothe flow size of the debris flow. When the flow of the debris flow is large, the movable flow guidance mechanisms are pushed to deflect to filter and divert the debris flow, and guide part of the filtered debris flow into the stopping and silting areas for storage. Therefore, the flow of the debris flow is reduced, and the impact and destructiveness of the debris flow are greatly reduced. Moreover, an interception system has strong resistance to geological hazards. Even if partial damage occurs, the prevention and control effect cannot be greatly affected.
