[0003] When installing prefabricated bridge piers, they are mainly suspended by cranes. Their verticality and elevation are mostly measured by sticking reflective stickers on the piers, and then measured by a total station to command the crane to adjust. However, this method requires repeated adjustments to the installation position of the bridge piers, which is inefficient and has poor installation accuracy.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] Please refer to Figures 1 to 5 , in the embodiment of the utility model:

[0031] A device for installing and positioning prefabricated piers of an assembled bridge comprises a positioning column 1, a fixing structure is arranged at the bottom end of the positioning column 1, a first mounting seat 2 is arranged at the bottom end of the positioning column 1, a first jack 3 is horizontally arranged on the first mounting seat 2, a positioning frame 4 is arranged at the inner end of the first jack 3, a second mounting seat 5 is arranged above the first mounting seat 2, a second jack 6 is arranged on the second mounting seat 5, a straightening frame 7 is arranged at the inner end of the second jack 6, and a level 8 is arranged on both the first mounting seat 2 and the second mounting seat 5, a third mounting seat 9 is arranged above the second mounting seat 5, a third jack 10 is arranged on the third mounting seat 9, and an introduction frame 11 is arranged at the tail end of the third jack 10.
