鄂北水资源配置工程2016年11标渡槽伸缩缝止水设计

Aqueduct Expansion Joint Waterstop Design of Water Resources Allocation Project in North Hubei Package 11 in 2016

通过对近年来多项渡槽工程伸缩缝止水设计及建成后效果分析,列出多种伸缩缝止水形式以及各自优缺点,供鄂北地区水资源配置工程龙泉河渡槽伸缩缝设计进行参考选择。最终根据使用条件以及所要达到的目标效果,在费用允许的条件下,龙泉河渡槽伸缩缝选择了复合止水形式,进行了多重防护。可为设计人员在需要考虑伸缩缝止水的其他渡槽等工程设计中提供参照方案,并增加对伸缩缝止水材料的了解。

Based on the analysis on the expansion joints waterstop design and effect after construction of many aqueduct projects in recentyears,various expansion joints waterstop types and their respective advantages and disadvantages are listed for reference and selectionin Longquan River aqueduct expansion joint design of water resources allocation project in northern Hubei. According to theapplication conditions and the target effect to be achieved,composite sealing form is adopted for the expansion joint of Longquan Riveraqueduct and multiple protection is adopted under the condition of allowable cost. This text also provides a reference for the designersin design of other aqueducts in which expansion joint waterstop is needed,and increase the understanding of expansion joint sealing materials.
