The invention discloses a
pile-beam integrated fully-prefabricated assembled bridge
substructure, a bridge and a construction method thereof.The
pile-beam integrated fully-prefabricated assembled bridge
substructure comprises a cover beam and a
pier stud, the cover beam is arranged in the transverse bridge direction, and the
pier stud is a prefabricated concrete
pipe pile column formed by pouring concrete in a pile core of a prefabricated concrete
pipe pile; the connecting joint of the upper end of the prefabricated concrete
pipe pile column and the cover beam and the prefabricated concrete pipe pile column are formed by one-time concrete pouring. According to the invention, a full-prefabricated
assembly concept is adopted, so that the integrated installation of the prefabricated concrete pipe pile column, the cover beam and the main beam can be realized. The construction method is easy to operate, convenient to construct, safe and reliable, the construction progress can be accelerated, the construction cost can be reduced, existing road transportation pipe piles can be utilized, construction shortcuts and construction temporary bridges do not need to be erected, occupied space is saved, good adaptability is achieved for regions with high construction environment requirements, and the construction method can be applied to the environment where the construction conditions are limited and shortcuts and temporary bridges cannot be erected. And full-prefabricated
industrial construction and quick construction can be realized in urban regions with busy traffic.
