Grouting Treatment of Sedimentary Dregs of Cast-in-place Bored Pile Bottom

The reasons for sediment,sediment's effect on the bearing capacity of cast-in-place bored pile and treatment with sediment are analyzed,and the effecting mechanism of grouting at the piles bottom is discussed. The technique is emphasized by means of practical work. The test indicates that grouting at the piles bottom is an effective method to deal with sediment and it improves the bearing capacity of piles.
