Ground anchor type abutment construction method

The invention provides a ground anchor type bridge abutment construction method. The ground anchor type bridge abutment construction method comprises the following steps that S1, a foundation is poured and expanded in a layered and blocked mode; S2, bridge abutment wall bodies and partition walls are poured in a layered and blocked mode; S3, the post-cast strip is poured in a layered mode; S4, a bridge abutment cover plate and a bridge abutment main beam are poured in a segmented and layered mode; S5, sand is filled in the manhole; S6, anchor rods are installed, and grouting is conducted; and S7, the prestressed steel strand (6) is tensioned in a segmented mode, and grouting is conducted. Temperature control is carried out on the large-volume enlarged foundation through the cooling pipelines, the pipelines can be recycled for secondary utilization, the cooling effect in the fluid movement process is obviously improved, the post-cast strip is arranged to release differential settlement, the problem that the ag
