| Abstract: | Combined with practical engineering,the author analyzes the causes of quality problems in bored cast-in-situ pile construction as water oozing from pile casting,collapse of hole wall,deflection of drilling,excess detritus quantities at pile toe and long borer auger,proposes preventive measures,and illustrates the causes and preventive measures of construction quality problems in the process of underwater concrete grouting as long pipe and floating of reinforced steel cage,which to offer a reference for similar project. |
