新型全装配式高桩码头施工技术

Construction technology of new prefabricated high-piled wharf

新型全装配式高桩码头结构主体采用模块化设计,由插槽式横梁、无底π形梁板等新型预制构件组成,结构新颖,构件尺寸和质量大、安装定位难度高,施工没有先例。以连云港港徐圩港区码头工程为例,分析新型高桩码头结构的应用优点,并针对码头结构的施工难题,提出新型构件预制、精确定位安装、空腔节点施工等技术措施。经工程实践证明,该施工技术措施先进、安全高效,可以为类似工程提供参考。

The main body of the new fully prefabricated high-piled wharf structure adopts modular design and is composed of new prefabricated components such as slot beam,bottomlessπbeam,the structure is novel,the components have large size and weight,high difficulty in installation and positioning,there is no precedent for construction.Taking the wharf engineering in Xuwei Port area of Lianyungang Port as an example,this paper analyzes the application advantages of the new high-piled wharf structure,and proposes technical measures such as new component prefabrication,precise positioning and installation,cavity node construction to solve the construction difficulties of the new wharf structure.The engineering practice is proved that the construction technical measures are advanced,safe and efficient,which can provide references for similar projects.
