Abstract: Due to the continuous scouring of flowing water during flood season, the pipelines in rivers and ditches are at the high risks of failure under the influence of dynamic water load. Hence, the timeliness and pertinence of the emergency rescue plan is the key to the successful emergency rescue. Herein, the disaster-causing mechanism and the main control factors of the pipeline floating over Zhuozhang River were analyzed based on the emergency floating situation of the 185.5 m section of Yu-Ji Pipeline(Yulin-Ji'nan) crossing Zhuozhang River. Meanwhile, the current safety status and risk changes of the pipeline were evaluated. In view of the main control factors of the emergency situation, an emergency rescue plan of pipeline venting + river dredging + spur dike + scaffold platform + pipe reinforcement with gantry frame was prepared by considering the safety, construction period, access conditions, and the availability of rescue resources.Further, the pipeline rescuers dealt with the emergency situation successfully by scientific means according to the new plan. In this way, the emergency situation of pipeline floating was controlled in time, the pipeline had the operation resumed in advance, and the secondary disasters were prevented.
