Engineering Design of Rotary-type Floating Bucket Barrier-drift in Water Diversion Project
The treatment problem that floating debris at the head of water diversion affect hydraulic structures and water quality cannot be ignored.Based on the basic idea of"block,guide and discharge",the floating bucket barrier-drift of the reservoir is reconstructed and a rotary one is designed.Experimental analysis and discussion of rotary floating bucket in different inflow,different installation angles and different floating objects are carried out.It is found that the bigger the incoming water flow is,the better the effect of drift guiding and drainage is,the reasonable installation angle plays an important role in driving the rotation of the bucket,and the mass and speed of floating objects play a positive role in guiding drift.Meanwhile,the design schemes of guiding and draining drift are given respectively for the reconstruction project and the new project.The design promotes the treatment of floating objects in diversion hydroproject and provide reference for the design of other types of multi-purpose hydroproject.
