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.
