水面漂浮物直接影响工程泄洪、发电、航运、水质、景观等,现有工程治漂方式不适应大规模治理要求,治理漂浮物是当前工程环保难题。为改善工程被动低效治漂方式,提出水力一体化治漂方案,在河道水力与结构自身提供的水力共同作用下,将漂浮物引导至指定部位拦、导、清(排)漂达到整体治漂效果,降低作业强度和清漂成本,形成长效治漂机制。2014年汛期长江科学院在三峡坝前通过浮桥导流式浮排开展水力一体化治漂生产试验,取得了在运行过程中拦漂、导漂的预期效果,为定位、集中、可控清漂提供有利条件。设施经船舶撞击、风浪、水位变化、水面反恐演练等检验,适应各种极端状况,结构定位安全可靠,可为工程安全运行提供防护屏障。

Floating debris directly affects hydraulic project’s spillway, power generation, navigation, water quality,and landscape. Floating debris is an environmental problem in engineering, but current approaches could not meet the requirements of large-scale treatment. To improve the passive and inefficient way of treating floating debris, we present an integrated hydraulic approach of treating floating debris by blocking, guiding, and removing debris under the joint action of hydraulics of river and floating row itself. Yangtze River Scientific Research Institute carried out tests using the floating bridge-style row equipped with guiding water power in front of the Three Gorges Dam in flood season of 2014. The floating debris were blocked and guided to a certain location and were removed concentratedly. During the test the facility was proved safe and reliable after going through extreme conditions inclusive of ship collision, waves, water level fluctuation, and counter-terrorism exercises on the water, providing a protective barrier in front of the dam on water surface.
