东庄水库导流围堰建设方案探析

Construction Scheme of Diversion Cofferdam in Dongzhuang Reservoir

为了确保东庄水库顺利建设,基于东庄水库工程概况、水文泥沙条件和导流时间顺序,在分析比较过水围堰与拦洪围堰2种方案和土石围堰与混凝土围堰2种结构形式优缺点的基础上,提出东庄水库导流上游采用混凝土拦洪围堰、下游采用土石拦洪围堰建设方案,并对围堰施工进行了探讨,为类似工程建设提供了借鉴。

In order to ensure the smooth construction of Dongzhuang Reservoir,based on the general situation of Dongzhuang reservoir project,hydrologic and sediment conditions and diversion time sequence,based on the analysis and comparison of the two schemes of overflow cofferdam and flood blocking cofferdam and the advantages and disadvantages of the two structural forms of earth-rock cofferdam and concrete cofferdam,the concrete flood blocking cofferdam construction scheme is proposed for the upstream of Dongzhuang reservoir diversion,and the earth rock flood blocking cofferdam construction scheme is adopted for the downstream.And the construction of cofferdam is discussed,which provides a reference for the engineering construction of similar projects.
