摘要
支盘灌注桩是在钻孔灌注桩基础上发展的一种新型变截面灌注桩.它的施工过程分为成孔、挤扩支盘施工、钢筋笼制作与安装、混凝土灌注等阶段.每个阶段分别加以质量控制,使工程按期、优质完成.
Underreamed bored castinsitu pile is a newly developed variable crosssection castinsitu pile based on bored castinsitu pile. Its construction includes the steps of hole shaping, reaming, the facture and fixing of reinforcing cage, and concrete cast. The quality control applied in each step will ensure the construction is completed on schedule and high grade.
