The utility model discloses an automatic perpendicularity control structure for bridge high pier construction. A laser plummet is installed on a poured first-section concrete plummet installation base of a bridge pier body, laser plummet laser target holes are reserved in corresponding positions of opposite corners of a formwork, a receiving laser target is installed on the top layer of the support formwork, and the receiving laser target ascends along with the support formwork. The laser plummet is used for transforming and processing a device with the wireless remote control function through a wireless remote control module and an alternating current power source converter. The automatic perpendicularity control structure is used for bridge high pier perpendicularity construction, and based on the principle that upward laser rays of the laser plummet are parallel to the pier body, the deviating conditions of the formwork can be clearly and directly observed through the formwork laser target at the top end.
