Engineering Practice of Post-grouting in Cast-in-situ Pile

Abstract:

The application of bored pile is restricted because of the hole bottom sediment and mudcake on pile, which is solved by the post-grouting technology in cast-in-situ pile construction. Combined with the engineering practice, the paper discusses the main technical points and control measures in construction of post-grouting and analyzed the affecting factors on holes “rushing” of grouting pipe and the technical measures to ensure the holes “rushing” of grouting pipe.
