静压预应力管桩遇较厚粗砂层解决措施的探讨

Discussion on Solving Measures of Static Pressure Prestressed Pipe Pile in Thick and Coarse Sand Layer

本文结合静压预应力管桩遇较厚粗砂层采用先长螺旋引孔后压桩的施工工艺,使预应力管桩穿透粗砂层进入设计要求的持力层和有效桩长,确保了施工质量和工期。

in this paper,the construction technology of long spiral leading hole and then pressing pile is adopted in combination with the thick sand layer of static pressure prestressed pipe pile,so that the prestressed pipe pile penetrates the thick sand layer into the required bearing layer and effective pile length,thus ensuring the construction quality and construction period.
