桩端压力注浆在人工挖孔灌注桩中的应用

Applying High Pressure Grouting in Concrete Pile Digged by Hand

以郑州市轻金属研究院为例,探讨了桩端压力注浆技术在人工挖孔灌注桩中应用的基本工艺。该工程基础原设计采用人工挖孔灌注桩,根据施工中出现的实际情况,又采用桩端压力注浆技术,取得了良好的效果。

This paper discuss a new technology of high pressure grouting used in the end of concrete piles digged by hand.There is a anstructure that was design ed using concrete piles digged by hand at first.Then they were strengthened by u sing this new technology, and the result is very good.
