@@@@Underwater concrete injection is the most important process in the construction of bored pile.There will be the phenomenon of tube rupture or collapse sometimes for the tremie in underwater concrete injection in ultra-deep hole.The direct reason why the phenomenon would happen was theoretically analyzed through stress analysis.Various factors which may cause tube rupture and collapse were listed based on the practice, and the corresponding preventive measures were put forward, which may be beneficial to the quality management of underwater concrete injection in ultra-deep hole.
