钻孔沉管后注浆工艺在预应力PHC管桩的应用

On application of drilling sinking pipes post-grouting in prestressed PHC pipe piles

通过介绍钻孔沉管后注浆工艺在PHC管桩上的应用,并结合实际工程,通过静载试验及经济效益比较,阐述了后注浆工艺对PHC管桩承载力提高的可行性,为今后PHC管桩后注浆工艺提供了设计、施工及试验参数。

According to the introduction of the application of the drilling sinking pipes post-grouting in prestressed PHC pipe piles,illustrates the feasibility for the post-grouting craft in improving the loading capacity of the PHC pipe piles by comparing the static loading test and economic benefits and combining with the factual projects,provide the design,construction and test parameter for the drilling sinking pipes post-grouting.
