强腐蚀环境下锤击PHC管桩施工技术

Construction Technology of PHC Pipe Pile Hammering in Strong Corrosion Environment

PHC管桩具有竖向抗压承载力高、施工工期短等优势,已在我国得到了广泛的推广运用。结合日照港油品码头有限公司油库二期工程中首次采用PHC管桩的工程实例,阐述了在强腐蚀环境下,PHC管桩的选用、防腐处理措施、锤击施工技术要点及施工控制措施,为类似工程提供一定的参考。

PHC pipe pile has been widely used in China because of its advantages of high vertical compressive bearing ca- pacity and short construction period. Combined with the engineering case of the second stage project of an oil depot in oil sharf of Rizhao port, PHC pipe pile was first used, this paper elaborated the construction in the PHC pipe pile selection, anticorrosion measures, points of hammering construction technology and control measures in strong corrosion condition, which can be reference for the similar engineering.
