[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a prefabricated bridge pier tilting device proposed in this utility model has the following specific structure: The prefabricated cap beam installation platform includes a winch 3, which is connected to a lifting ring 2 on the precast pier 1 via a steel wire rope 4. The winch 3 has a lift of 3m, and the steel wire rope 4 has a diameter of 1.5cm. The winch 3 is mounted on a column 5, which is bolted to a bottom beam 17. One side of the column 5 is supported by a stiffening device 6, which is fixed to the bottom beam 17. The bottom beam 17 is 600cm long, and the column 5 is 80cm high. The bottom of the precast pier 1 is equipped with a hoop 9, two sides of which are connected to a side plate 10 via a pivot 8. The side plate 10 is bolted to the bottom beam 17 and is 100cm high. The other two sides of the hoop 9 have a support block I11 on one side and a support on the other side. Support block II7 and jack 12 are fixed on the bottom beam 17. Their output shafts are connected to support block I11 on the sleeve 9. The sleeve 9 has a length and width of 120cm and a height of 60cm. Jacks 213, 314, and 415 are fixed to the bottom beam 17 at intervals. According to different flipping angles, the output shafts of jacks 213, 314, and 415 are respectively connected to support block II7. When jacks 213, 314, and 415 are working, their output shafts are connected to support block II7. Support timber 16 is provided on the left side of jacks 213, 314, and 415. Support timber 16 is fixed on the bottom beam 17 to form a prefabricated pier flipping device that works together.

[0016] The above-mentioned prefabricated cap beam installation platform includes the following sequential steps: Step 1: Fabricate and install the pier tilting device Fabricate and install the base beam 17, which is 600cm long.
