结合具体工程实例,详细介绍了PHC预应力管桩静压法施工工艺与方法,提出了管桩施压质量通病的防治措施。通过桩基检测表明该工程PHC预应力管桩符合设计要求,指出高强混凝土预应力管桩具有质量可靠、单桩竖向承载力等优点,值得推广。 Combined with specific engineering examples, the construction process and method of the static pressure method of PHC prestressed pipe piles are introduced in detail, and the prevention and treatment measures for the quality defects of pipe piles are proposed. The pile foundation test shows that the PHC prestressed pipe pile meets the design requirements. It points out that the high-strength concrete prestressed pipe pile has the advantages of reliable quality, vertical bearing capacity of single pile, and is worthy of promotion.
