摘要
Abstract
The formation structure of the boulder-strewn river is loose,the voidage is large,and the permeability is strong,and the reinforcement effect is poor because of the slurry stringing and leakage in the rotary jet rein-forcement.Seepage control walls,due to their excessive occupation of the river channel during construction,long construction period,and high cost,are not suitable for all foundation reinforcement projects in boulder-strewn river channels.Through describing the construction technology for combined reinforcement with steel pipe piles and jet grouting used for middle piers of Jinlong Dadu River Bridge,this paper puts forward solutions and methods for a series of challenges in foundation reinforcement construction of boulder-strewn river chan-nels,such as pipe sinking,hole deviation control,hole leakage,schedule control and cost control,and imple-ments these measures,achieving good results.关键词
