Construction method capable of achieving large-diameter deep stirring based on resistance reducing manner

The invention discloses a construction method capable of achieving large-diameter deep stirring based on a resistance reducing manner, and belongs to the technical field of pile foundation construction. Through organic combining of the resistance reduction material and a stirring drill machine, the following steps are adopted for achieving the construction method of the large-diameter deep layer,and the steps comprise construction site preparing, and construction equipment configuration and transforming; resistance reduction material and curing material configuration; stirring drill-down construction; stirring drill-up construction; secondary stirring drill-down construction; secondary stirring drill-up construction; and finishing stirring work and ending construction when a stirring drill bit is lifted to the design height. The structural manner of a traditional drill bit is changed, and the function of reducing the resistance is achieved; through spraying of an ionic surfactant solution, resistance of stirr
