Technical procress of post-grounting in cast-in-place percussion drilled pile

通过在建超高层项目基础工程冲孔灌注桩后注浆法的成功案例,来阐述后注浆法必须注意的现场技术措施,通过技术措施来实现冲孔灌注桩后注浆对于提高桩基承载力及减少沉降量的设计目标。

Explain Practical procress used in site post-grounting according to a successful finished pilliing foundation construction,show the key technical process is the right way to use the Post-grounting method to increase the pile bearing capacity.Meanwhile,it is a good solution to reduce the pile settlement to meet the design goal.
