悬板在低水头引水防沙工程中的应用

为了推广悬板在低水头引水防沙工程中的应用，概括介绍了悬板在悬板分层式引水和排沙漏斗中的成功应用经验：将皮氏堰改为流线堰后，在悬板下断面平均流速减小不多的情况下，悬板上水面形状更为简单，可改善枢纽的引水防沙效果：将悬板应用于排沙漏斗中，可将排除的泥沙粒径减小到0.1mm，同时减小排沙耗小量，提高排沙率。

Optimizing Design of Water Diversion Works of Shenzhen-Dongjiao Water Supply Project

In order to spread applying suspended slabs to sediment prevention works of low head water diversion projects, some experiences with applying suspended slabs to stratified water diversion and desilting funnel are summarily described as follows:after changing a Pishiweir for a streamlined weir, under condition of that the cross section, which is below the slab, average flow velocity decreases a bit, then the configuration of the water surface above the slab will to be more simple, it will improve effects of water diversion and desilting; applying suspended slab to desilting funnel, it will decrease the prevented sediment's grain diameter to 0.1mm, meanwhile water consumption for desilting will be decreased so as to raise sediment delivery rate.
