Application Research on Hydraulic Technology for Drilling Pile Testing

Dual hydraulic technology (includes hydraulic loading box and hydraulic grouting) is one of the most popular engineering measures that has found widespread application in the field of foundation pile engineering. In this paper, according to practical situations of drilling pile testing, working mechanism, construction technology and application of movable load-transferring pile with embedded hydraulic box installed near the bottom of large-scale foundation pile were introduced. Through cyclic applications of dual hydraulic technology for pile segments near the hydraulic box, both compaction of pile-end sediment and grouting around the pile can be achieved. With this method, bearing capacity of foundation pile can be enhanced effectively, and pile-soil cementation can be improved. Moreover, verification data for vertical bearing capacity of single pile can be achieved.
