江西廖坊水利枢纽拦污浮排设计

为避免水体中的漂浮物堵塞水电站进水口而影响电站的正常运行，一般要在电站进水口前设置拦漂清污装置。但多数电站拦污装置的运行效果不甚理想，而江西廖坊水电站拦污浮排装置的运行效果颇佳，具体设计为：采用浮排、锚头及垂直升降的卷扬机组成浮排装置，浮排由36节双浮筒和挂栅构成，每节长度7.6 m，节间十字铰接可双向转动，浮筒直径0.7 m，挂栅高0.9 m，栅条间距0.2 m，双浮筒下面的栏栅伸入水下1.37 m。重点介绍了该装置的设计特点和设计体会。可为同类工程设计参考。

Design of pontoon trash raft for Liaofang Hydraulic Complex

Floating-debris deposing facilities should be arranged generally at the intake of a hydropower station to avoid blocking.The trash disposing system of Liaofang Hydropower Station in Jiangxi Province has a better operating effect than those of most hydropower stations.Its pontoon trash raft consists of floating rows,anchor heads and vertical hoist.The floating rows are composed of 36 pairs of pontoons and hanging trash racks,7.6 m long each and hinged with two-way rotations.The diameter of each pontoon is 0.7 m,and the height of each hanging rack is 0.9 m with a space of 0.2 m.The hanging racks under the pontoons submerge into water for 1.37 m.The design features as well as the design experiences are introduced.
