    • A set-up/down plural-span weir assembly is made of flexible sheets and comprises a plurality of single-span weirs coupled to each other through pillars across the stream of a river. A pressure medium is introduced into the bags of the single-span weirs to inflate them to set up the single-span weirs and also discharged therefrom to deflate them to set down the single-span weirs. The upstream water of the weir assembly is directly introduced from an upstream water level detection pipe into a bucket or float container of at least one of the single-span weirs, and is indirectly introduced from the upstream water level detection pipe into the bucket or float container of at least another one of the single-span weirs through the bucket or float container of the former one of the single-span weirs or through that of still another one of the single-span weirs.
    • 设置/下降多跨堰组件由柔性板制成,并且包括通过跨越河流的支柱彼此连接的多个单跨堰。 将压力介质引入到单跨堰的袋中,使它们充气以设置单跨堰,并将其从其中排出以将其放气以将单堰堰放下。 堰组件的上游水从上游水位检测管直接引入到单跨堰中的至少一个的铲斗或浮体容器中,并从上游水位检测管被间接引入桶或浮子 至少另一个单跨堰的容器通过前一个单跨堰的铲斗或浮体容器,或通过另一个单跨堰的另一个。
