Abstract: In July 2021, an extreme rainstorm occurred in Henan Province. China Anneng Group provided full play to its professional advantages and successfully completed the task of managing major dangers. Following innovatively technologies were applied: used power boat bridges to rescue people who were trapped in floods in Xinxiang city, adopted multi-type highpower drainage trucks "multi-faceted, cascade relay" to forcefully drain the water in the JingGuang Tunnel, blocked the breach of the Weihe River by the method of "covering the head on the right bank and protecting it with a single block on the left bank", took excavation of a discharge channel on the right bank of the dam body to relieve the danger of dam failure of Guojiazui Reservoir. It was analyzed that scientific programs, professional teams and advanced equipment were the key factors for the success of emergency rescue technology. And it was proposed that to strengthen the basic research of disaster science and engineering, build a strong emergency rescue professional team, develop and distribute advanced emergency rescue equipment, were the three important things to strengthen the emergency rescue capabilities of flood disasters.
