预应力管桩静压法施工技术与质量控制要点

Construction Technology of Static Pressing Method of Prestressed Pipe Pile and Key Points of Quality Control

预应力管桩因其施工简便,越来越多地被应用于建筑工程的基础。常用的管桩一般为预应力高强混凝土管桩(PHC桩)和预应力混凝土管桩(PC桩)。其沉桩方法有多种,包括锤击法、静压法、震动法、射水法、预钻孔法等。本文以静压法施工为研究对象,简单论述静压法的施工技术和其质量控制要点。

Prestressed pipe pile is increasingly applied in the foundation of con- struction engineering due to simple construction. Frequently-used pipe piles include PHC pile and PC pile. Its pile-sinking methods include hammering method, static pressing method, vibration method, water jetting method and predrilling method. Taking static pressing construction as research subject, this article gives a brief explanation of construction technology of static pressing method and its key points of quality control.
