    摘要:

    某海外深水防波堤工程中选用了国内的扭王字块作为护面结构,但国标中有关扭王块安装规则的内容较少,因此在与外方咨工交涉过程中遇到一些安装细则的困扰,如扭王字块的最佳坡比,块体的详细姿态要求,堤身、堤头、堤顶等位置的具体安装顺序等问题。参照国外同类块体的技术,总结了数十年来我国工程技术人员在设计、物模试验、施工中积累的安放经验,整理出扭王字块安装中一些有益的安装细则,可为类似工程提供参考。综合而言,定点随机安装是最能充分发挥扭王字块优异水动力性能的安放方法。安装点位预定义图、水下可视化安装等新技术的应用能大幅提高扭王字块的安装质量。

    Abstract:

    The Chinese pode is chosen as the armour layer in a deep-water breakwater of an abroad project,but there are few descriptions of Chinese pode in Chinese standards,some detail placement issues are encountered with international consulting engineering during the process of projects,such as the best slope ratio of Chinese pode,the detailed attitude requirements of concrete armour units,and the placing sequence for embankment body,embankment head and embankment top.Compared with the technology of similar concrete armour units developed by other countries,summarized the decades placing experience of Chinese pode from engineers of designation,model testing,and construction,several beneficial detailed placement rules are concluded in this article,which also provides some useful references for similar project.In general,predefined-point random installation is the most efficient placement way to achieve the best hydraulic performance.The predefined location drawing of Chinese pode,and the newly developed technology of underwater visitation system can greatly promote the placement quality.
