Title: PRESSURE GROUTING UNDER BORED-PILE TIP IN COBBLE LAYER
Abstract: Pressure grouting under pile tip means that after a bored pile is poured,through the pipes embedded in the pile and the pressure-grouting device pre-placed at the pile end,cement mortar,which can be solidified,is continuously injected into earth under pressure so as to improve the pile's load bearing capacity and reduce the settlement of pile foundation.Vast engineering practice indicates that the adaptability of this technology varies in different soil layers.Site test proves that it has a very good performance in cobble layer,achieving a remarkable social and economical benefit.
