Integral one-time pouring construction method of large-volume concrete for special-shaped pier stud

The invention discloses an integral one-time pouring construction method of large-volume concrete for a special-shaped pier stud. The construction method comprises working procedures of pre-construction preparation, manufacturing and mounting of pier-stud steel bars, template lofting, template designing, template processing, template mounting, concrete pouring, maintenance, template removal, transverse-beam drawing, mud jacking construction and the like. The construction method disclosed by the invention adopts large-area shaping steel templates; through the integral one-time splicing of pier body templates and in the manner that the overall pier body templates are reinforced by a purlin system at the peripheries of the templates, a finished pier body without tie rod holes is realized; during the construction of concrete vibration, a vibration method that an immersion vibrator is used as a main device, and an attached vibrator is used as an auxiliary device is adopted, so that the overall appearance quality and the geometric dimensioning precision of the finished pier stud are greatly improved; besides, the construction safety is guaranteed, and the construction cost is reduced.
