桩底压力灌浆加固钻孔灌注桩基础的工程应用

A Practice of Consolidating Drilling Hole Pour Pile Foudation with Pressure Grouting Under Pile Bottom

通过对某桩基工程桩端破碎岩石进行高压灌浆加固处理的工程实例,论述了桩底压浆工艺可改善桩端及桩周的边界条件,提高桩基的承载力,从而达到对桩基加固处理的目的.

This paper is bout a practice of consolidating crash rock in the end of drilling Hole Pour Pile Foudation with Pressure Grouting Under Pile Bottom. The pressure grouting technic, which can enhance boundary condition of pile end and peripheral, improve pile capacity and consolidate pile foudation, was discussed.
