湍惠渠渠首坝施工导流方案比选

The Comparative of Diversion Scheme for the Head Dam of Tuanhui Canal

灌区渠首坝施工导流方案比选是渠首坝施工技术内容的重要组成部分,对加快渠首坝施工建设具有十分重大的工程意义。为此,结合邓州市湍惠渠灌区的水源工程湍惠渠首坝施工导流方案比选实践案例展开分析探讨。结果表明,在全面熟悉湍惠渠首坝工程概况的基础上,针对湍惠渠灌区水源工程的拦河坝施工及其导流沟建设方案,着重展开灌区渠首坝施工导流方案比选,最终优选推荐渠首坝施工导流方案一(钢板桩防护加铅丝石笼护脚措施),作为经济合理且能满足汛期防冲要求的最优方案。此研究成果既为以后导流沟支护积累了经验,也为类似工程建设实践提供了借鉴参考。

The comparison of the construction diversion scheme in irrigation area is an important part of the construction technology involved in canal head dam projects,and it holds significant engineering significance for accelerating the construction process.Therefore,the analysis and discussion of the pilot case for the water source project of in the irrigation area of Tuanhui Canal,Dengzhou City is conducted.The results indicate that on the basis of a comprehensive understanding of the turbulence canal dam project overview,the recommended diversion scheme for barrage and diversion channel construction primarily focuses on irrigation dam construction.After final optimization,it is suggested to adopt a canal dam construction diversion scheme(including steel plate pile protection and lead wire cage foot protection measures)which is both economically viable and capable of meeting flood season requirements.This research result not only contributes to the accumulation of knowledge for future diversion ditch support,but also serves as a reference for similar engineering construction practices.
