Abstract: Hanjiang River Basin is subject to frequent floating aquatic plants which affect the ecological environment, power generation, shipping, and water supply. At present, the treatment of floating objects for hydropower projects mostly relies on human labor or mechanical action, which has safety problems and low efficiency. According to the characteristics of floating debris in Hanjiang River and the operation of Nianpanshan hydropower project, we adopt a hydraulic integrated floating raft at the approach channel to guide and discharge the floating debris to the sluice gate based on analyzing and comparing the load and structural safety and stability in the design schemes. The floating debris is discharged to the downstream through the sluice gate in due course. This developed technical equipment and the test results are conducive to the generation benefits of the power station and in the meantime ensure the safe operation of the project. The integrated hydraulic treatment adapts to the needs of various engineering and overcomes the difficulties in treating floating debris.
