The invention discloses a construction technology for pier columns, relates to the field of buildings and mainly aims at solving the problem of insecure construction of the pier columns. The construction technology comprises the following steps: S1, processing a template while carrying out measurement lofting; S2, treating junction surface; S3, producing steel bars and binding a pier column with first-grade steel bars; S4, installing and shaping a steel form, rectifying the form and positioning; S5, inspecting form steel bars, pouring with first-grade concrete and then producing a briquette; S6, binding the pier column with second-grade steel bars; S7, installing a second-grade steel form and pouring the concrete; S8, repeating the operations in the steps S1 to S7 to the top of the pier column, then removing the form and carrying out concrete curing. The construction technology disclosed by the invention has the advantages that the construction efficiency of the pier column can be improved and the construction hazard is greatly reduced; the fastness is significantly improved by binding the pier column with multi-grade steel bars and repeatedly pouring the concrete; the constructionflow is strictly implemented to ensure safe production and prevent accidents.
