| Abstract: | Prestressed rotary jet mixing pile anchoring technology was described,including bored mixing,pile-pulling re-jetting and string pulling.Foundation pit was monitored via slope top lateral displacement and slope top settlement.The results show that the foundation pit supporting that combines self-boring type prestressed jet mixing anchor pile and punched fender pile has the advantages of convenient construction,small displacement of foundation side and low general cost.It is indicated that provided the surrounding conditions are suitable,the prestressed rotary jet mixing pile anchoring technology is of high adaptability with favourable economical returns for large-span deep foundation pit supporting. |
