The geological conditions of the Dachao Expressway are complex,and the construction of high piers is difficult.The applica-tion of hydraulic climbing formwork technology is representative.The hydraulic climbing model points,working principles,and basic structures of high piers on the Dachao Expressway are summarized.Based on practical engineering experience,this paper analyzes the control points of pre-embedding the climbing cone,installing the frame,and removing the formwork in the hydraulic climbing form-work construction of high piers on the Dachao Expressway.The verticality and appearance quality control measures are summarized.
