As an improvement of the embodiment, the bent cap formwork comprises a bottom formwork 9, a side formwork 10 and an end side formwork 11; and a counter-pull rod 12 for fastening is arranged between the end head side dies 11.

The specific construction method comprises the following steps:

1) hoop installation

Using a zigzag ladder and a tooling platform to provide a hoop mounting operation surface, measuring the top elevation of a pier stud 1 by a leveling instrument, then guiding the height of the hoop 2 of the pier stud 1 by a steel ruler, wherein the top mounting elevation H of the hoop 2 = the height of a cover beam bottom, the thickness of a bottom die, the thickness of a batten, the height of a distribution beam, the height of a girder I-shaped steel and the height of a sand box, the installation of the hoop 2 is carried out only when the concrete strength of the pier stud 1 reaches more than 100% of the design strength, in order to increase the friction force between a steel belt of the hoop 2 and the pier stud 1 and protect the concrete appearance of the pier stud, a geotextile with the thickness of 3mm is additionally arranged between the hoop 2 and the pier stud 1, during the installation, the hoop 2 is closely attached to the pier stud 1, high-strength bolts 3 are symmetrically screwed one by adopting an electric torque wrench, each bolt is screwed by adopting double nuts, and the structure;

2) mounting of support structures
