Study and implementation of hydraulic integrated floating debris control and reservoir surface security system for water control project

In order to improve the defects of inter-independence among functions, passive operation, lower efficiency, etc. of the existing floating debris control measures for water control project and then ensure the project benefits and the safety of the water surface, the technologies for barraging, guiding, cleaning ( discharging) and controlling floating debris are studied herein by hydraulic model experiments made with floating-raft, floating-trough and floating-gate for the hydraulic integrated floating debris control in accordance with the properties of floating debris, river regime and the characteristics of project layout, from which the effects from the integrated comprehensive controls according to the specific conditions are obtained from the schemes of several combinations of the experiments, in which the main technology——floating-raft for the hydraulic integrated floating debris control can not only realize active and large amount of debris control for barraging all kinds of large-sized dangerous floating debris through the engineering test made on the actual in situ application, but can also decrease the relevant intermediate operation links as well. The study result shows that the mode of the hydraulic integrated floating debris control is adaptable for the properties of debris and improves the floating debris control mode, thus can provide a technical support for the long-term effective and stable floating debris control for water control project, of which its practical equipment can be applied to all kinds of relevant projects for laying a technical basis for establishing the water surface security systems for the projects concerned.
