PILE-END PRESSURE GROUTING TECHNOLOGY EFFECT ON THE CARRYING CAPACITY OF BORED PILE

摘要：

　　Construction method,and technology have great influence on single pile carrying capacity of bored pile,especially effect on the hole-making technology and grouting technology.Bored Pile with pile-end pressure grouting technology has been widely used in high-rise buildings and large public buildings in Chinas Inner Mongolia region and this kind of bored pile is an advanced scientific methods that can raise carrying capacity of bored pile and reduce the pile foundation settlement.By pile foundation construction of high-rise buildings in Chinas Inner Mongolia region,using pressure grouting of pile tip engineering example,through static load test,high-strain inspection and the detection result of drilling core pulling to determination and analysis of the vertical bearing capacity of single pile that indicate pressure grouting pile end bored pile carrying capacity in the sand layer improved significantly.
