Summary:The utility model relates to the technical field of water conservancy and hydropower engineering construction diversion. The diversion tunnel hole plug energy dissipation structure comprises a diversion tunnel and an ecological drainage hole formed in the diversion tunnel, a plurality of stages of hole plugs are arranged in the diversion tunnel and located on the upstream of the ecological drainage hole, each stage of hole plug comprises a hole plug plug built along the cross section of the diversion tunnel, and a plurality of hole plug drainage holes are formed in each hole plug plug. According to the diversion tunnel plug energy dissipation structure, high-speed water flow is prevented from scouring and damaging an original diversion tunnel body section and an outlet in the downstream side of the ecological drainage tunnel, the operation safety of the reconstructed ecological drainage tunnel is guaranteed, and meanwhile the problem that cavitation and cavitation erosion damage possibly exists in the plug wh
