摘　　要：在传统高桩码头结构中,桩芯、桩帽常采用现浇工艺。受潮位变动区影响,现浇过程中钢筋、混凝土受海水浸泡侵蚀,难以控制结构质量。并且海上作业需要赶潮施工,人员风险性高。依托福建宁德18~20号泊位工程,介绍一种高桩码头承插式T形桩帽施工工艺。通过将T形桩帽承插式安装至钢管桩内,并利用UHPC材料灌浆与钢管桩形成整体。T形桩帽为一种新型结构,通过研究其安装、灌浆工艺,解决了高桩码头直桩装配化技术问题。应用结果表明,该工艺可以提高码头的装配化率和施工质量,应用效果良好。In traditional high pile wharf structures,the pile core and pile cap often adopt cast-in-place process.Due to the influence of tidal fluctuation zone,the reinforcement and concrete in the cast-in-place process are subject to seawater soaking and erosion,which makes it difficult to control the quality of the structure.Moreover,the marine operation needs to catch up with the tide construction,and the risk of personnel is high.Relying on the berth 18-20 project in Ningde,Fujian,this paper introduces a T-pile cap construction process using high pile wharf socket.By installing the T-shaped pile cap socket into the steel pipe pile and using UHPC material grouting to form a whole with the steel pipe pile.The T-pile cap is a new type of structure,and the installation and grouting process solves the technical problem of assembling straight piles for high pile wharf.The application results show that the process can improve the assembly rate and construction quality of the wharf,and the application effect is good.
