Abstract

Abstract

On the basis of a defect pile detected by two different methods before treatment,the property,position and size of the defect are analyzed and determined.According to the severity of the defect,ceutral hole extraction method is innovatively adopted.Concrete defects are treated with special machinery and artificial method in pile body,and concrete is poured after treatment.The results show that the defect treatment method is effective and can avoid the defects which can not be eradicated by using the traditional method such as grouting,thus this methed saves the time limit as well as the cost.
