Pile-beam integrated fully-prefabricated assembled bridge substructure, bridge and construction method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the prefabricated assembly technology of road and municipal road bridges, and in particular relates to a pile-beam integrated bridge substructure, and also relates to a bridge including the pile-beam integrated bridge substructure and a construction method thereof. Background technique [0002] With the rapid development of my country's economy in recent years, industrialized construction and rapid construction of bridges have gradually become the development direction of the construction industry, especially in densely populated urban areas or across busy roads. However, the construction of traditional bridges cannot meet the requirements of rapid construction. The reason is that most traditional bridges use pier-column lower parts, which are connected to the upper structure through cover beams, and adopt the cast-in-place construction method. The following problems exist in the construction process: 1. The large number of on-...

However, the construction of traditional bridges cannot meet the requirements of rapid construction. The reason is that most traditional bridges use pier-column lower parts, which are connected to the upper structure through cover beams, and adopt the cast-in-place construction method. The following problems exist in the construction process: 1. The large number of on-site labor force does not adapt to the development trend of an aging society, and
