The invention discloses a high bridge pier self-lifting outer frame over-form device which is simple in structure, can enhance over-form safety and improves over-form efficiency. The over-form device comprises outer support systems, telescopic devices, an upper formwork system and a lower formwork system. The upper formwork system is located above the lower formwork system. The upper formwork system and the lower formwork system both comprise a layer of formworks forming a high bridge pier pouring cavity. The outer surface of the formworks of the upper formwork system and the outer surface of the formworks of the lower formwork system are both provided with reinforcing transverse back ridges. The reinforcing transverse back ridges on every two adjacent formworks are connected through reinforcing transverse back ridge connecting pieces, so that the reinforcing transverse back ridges tightly hold the outer surface of the upper layer formwork system. The upper end and the lower end of each formwork in the upper layer formwork system are both provided with one outer support system. Each outer support system comprises a crank arm beam, a straight beam and a vertical guide column. The over-form device is easy to operate, quality is controlled more easily, the speed is higher, cost is lower, and safety is higher.
