摘要
现行高桩码头结构中,与桩基连接的桩帽或横梁一般采用现浇工艺。依托连云港港徐圩港区码头工程,采用一种插槽式预制构件与桩基形成连接的上部结构,桩芯预埋型钢插入该构件内置空腔内,通过后浇空腔节点与桩基形成连接。插槽式构件为一种新型结构,分析其预制施工工艺,并研制出一种免拆模凿毛施工工艺。结果表明,该工艺可解决空腔支模拆模的技术难题,提高新结构的预制效率和质量。
In the existing high-piled wharf,the pile cap or beam connected to the pile foundation generally adopts the cast-in-place process.Based on the wharf project in Xuwei Port area of Lianyungang Port,this paper adopts a superstructure with a slot-type prefabricated component connected with the pile foundation.The pile-core embedded steel is inserted into the built-in cavity of the component and connected with the pile foundation through the post-pouring cavity node.The slot-type component is a new structure,so this paper analyzes its prefabricated construction process and develops a mold disassembly-free chiseling construction process.The results show that this process can solve the technical problems of mold supporting and disassembling in the cavity,improve the prefabricated efficiency and quality of the new structure,and provide a reference for similar projects in the future.
