浅论钻孔灌注桩后压浆技术的施工

Construction of post grouting technology of cast-in-place bored piles

基于对后压浆技术机理的认识和对混凝土灌注桩存在问题的原因分析 ,阐述了后压浆技术施工方法、工艺流程以及质量控制要点 ,有效地消除了钢筋混凝土灌注桩的弊端 。

Based on the understanding of the mechanism of post grouting technology and analysis on the problems existed in concrete driven cast in place pile the construction method, technological process and quality control in post grouting construction are elaborated. Through those introductions the faults of reinforcement concrete driven cast in place pile are eliminated effectively and the bearing capacity of single pile is greatly enhanced.
