分水工

分水工是从一条水管或是灌溉用的供水渠道将水分配至两条以上的水管或是渠道，并且设有闸门或是闸板，让其具有针对性供水以及调节渠道水位的功能的一种组织结构。[1][2]

功能

当分水工分水处不需经过测量水量后再进行供水时，一般采用比率分水，可随当时渠道之水流量变化来进行针对性的分水。当分水工须先测量水量再进行供水时，可以利用闸门或闸板在分水工进行各渠道的水量分配。[1]

实例

林内分水工是一座直径100米、面积8660平方米、深度6.8米的小型水库。采用八角形分水工。最高蓄水量45000立方米，主要是提供麦寮地区的工业用水。 [3]

分类

依水理性质可将分水工分类如下：[1]

  • 潜流型-孔口式
  • 水门式
  • 涵管式
  • 短嘴式
  • 溢流型-明槽式
  • 堰式
  • 比率式
  • 控制闸式
  • 混合型-分水井式
