摘　　要：为了减小浑水水力分离清水装置(简称装置)的高度,将装置底部椎体的径坡变缓,并在底部布设有压渗水管,以冲刷椎体径坡变缓后淤积泥沙,试验所得结果与前期研究规律基本一致。通过排沙结构的优化试验达到了减小装置高度、顺利排沙和降低排沙耗水率的目的。为装置的推广应用提供了更为有利的条件和经验。In order to reduce the height of a hydraulic seperation device of turbid water（shorter form： device）,the diametric slope of the device would be slowed in the bottom of the vertebral body,and the pressure infiltration pipe would be laid in the bottom so as to scour the sedimentation after the slope to be slowed.It is known that the test results are consistent with the laws from previous studies.Through the optimization of the sediment desilting structures,such the aims are achieved as reducing the height of the device,desilting the sediment smoothly and reducing the water consumption rate,thereby providing more favorable conditions and experiences for the application and dissemination of the device.
