摘要
分期导流是用于水利工程中宽河床及大流量河流的一种常见的导流方法,以便分段对主体工程进行施工。以威宁中水提水工程为例,介绍了该工程的地质条件、工程特点及工程任务,根据对导流标准及导流方式的选取进行水力学计算后,对分期围堰进行设计并阐述其施工方法,分析了分期导流的优缺点,总结经验。
Staged diversion is a common diversion method for wide riverbed and large flow rivers in water conservancy projects,so that the main works can be constructed in sections.Taking Weining reclaimed water pumping project as an example,this paper introduces the geological conditions,engineering characteristics and engineering tasks of the project.According to the hydraulic calculation of the selection of diversion standard and diversion mode,the stage cofferdam is designed and its construction method is described.The advantages and disadvantages of stage diversion are analyzed,and the experience is summarized.
