青岛泉心河水库面板及附属结构施工优化技术措施

Optimization Technical Measures for Construction of Panel and Auxiliary Structures of Qingdao Quanxinhe Reservoir

面板堆石坝的面板混凝土施工工序包括上游固坡处理、表层止水施工、混凝土浇筑等,是一个全过程的质量管理控制过程,青岛泉水河水库面板堆石坝在面板及附属结构工程施工过程中采取了趾板上游破碎岩层斜坡面加固处理、大坝上游固坡面两油两砂即时碾压装置、大坝填筑防脱空灌浆管系统、半成品铜止水卷材支撑旋转装置、大坝面板的混凝土浇筑入仓装置等施工技术优化改进措施。实践表明,以上技术优化措施的应用促进了施工进度,有效的实现了质量、安全、进度的同步开展,希望为类似工程施工提供借鉴。

The construction process of panel concrete for face rockfill dams includes upstream slope reinforcement,surface water stop construction,concrete pouring,etc.It is a quality management and control process throughout the entire process.During the construction process of the Qingdao Quanshuihe Reservoir panel rockfill dam and its ancillary structures,construction technology optimization and improvement measures were taken,including reinforcement of the upstream broken rock slope surface of the toe slab,instant rolling device for two oil and two sand on the upstream fixed slope surface of the dam,anti void grouting pipe system for dam filling,semi-finished copper sealing roll support rotating device,and concrete pouring and warehousing device for the dam panel.Practice has shown that the application of the above technical optimization measures has promoted construction progress and effectively achieved the synchronization of quality,safety,and progress,so as to provide reference for similar engineering construction.
