Concrete arch bridge vertical pile construction technology

The invention discloses a concrete arch bridge vertical pile construction technology, and relates to the technical field of building construction. Comprising the steps that construction is prepared, and the positions of vertical piles are determined; a first section of the pile hole is excavated, and a lock opening is built after the first section of the pile hole is excavated; formwork erecting and pouring are conducted on the protection arm of the first section of the pile hole, and the first section of the pile hole is formed; erecting a vertical transportation bracket at an upper opening of the pile hole; removing the formwork when the strength of the first section of retaining wall meets the design strength requirement; excavating a pile hole below the first section of pile hole; after the pile hole overall excavation operation is completed, the pile hole is checked and accepted; reinforcing steel bars are installed in the pile holes, and reinforcing steel bar net racks are formed in the pile holes; and
