Fabricated reinforced concrete bridge pier and construction method thereof

Abstract

The invention provides a fabricated reinforced concrete bridge pier. The fabricated reinforced concrete bridge pier comprises a hollow bridge pier shell and cast-in-place core concrete arranged in thebridge pier shell, the bridge pier shell comprises a concrete layer and a reinforcement cage, and the reinforcement cage is arranged in the concrete layer; and the reinforcement cage comprises a plurality of circumferential stirrup meshes and a plurality of vertical steel bars, the multiple circumferential stirrup meshes are equidistantly arranged at intervals in the vertical direction, and the multiple vertical steel bars are equidistantly arranged at intervals along the circumferential stirrup meshes. The invention provides a construction method of the fabricated reinforced concrete bridgepier, the reinforcement cage and formworks are manufactured, then concrete is poured into spaces between the formworks and congealed into a whole so as to form the integrated bridge pier shell, the bridge pier shell is transported to a construction site, and the cast-in-place core concrete is poured into a hollow hole of the bridge pier shell. According to the fabricated reinforced concrete bridgepier and the construction method thereof, the weight is small, the construction period is short, transporting and hoisting difficulty is greatly reduced, multiple construction ways are provided, andoverall performance after the structure is formed is good.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to an assembled reinforced concrete bridge pier and a construction method thereof. Background technique [0002] Traditional bridge construction generally adopts two methods: cast-in-place concrete construction method and precast concrete construction method. The existing cast-in-place concrete construction method is to first bind vertical steel bars and stirrups at the construction site to form a steel cage, then support and set up formwork around the cross-section of the pier, and pour concrete. After the concrete solidifies to the preset strength, finally The formwork around the pier is removed. Therefore, the cast-in-place concrete construction method has the following disadvantages: (1) The construction period is too long and the construction efficiency is low; (2) There are many construction steps and the process is complicated; (3) The construction quality is not conducive t...

The existing cast-in-place concrete construction method is to first bind vertical steel bars and stirrups at the construction site to form a steel cage, then support and set up formwork around the cross-section of the pier, and pour concrete. After the concrete solidifies to the preset strength, finally The formwork around the pier is removed, so the cast-in-place concrete construction method has the following disadvantages: (1) The construction period is too long and the construction efficiency is low; (2) There are many construction steps and the process is complicated; (3) The construction quality is not conducive to control

[0003] The existing precast concrete construction method is to complete the production steps of the cast-in-place concrete construction method in the factory, then transport the solid concrete pier completed in the factory to the construction site, and finally lift and install the solid concrete pier. Therefore, the precast concrete construction method There are the following disadvantages: (1) The weight of the prefabricated pier is relatively large, which brings great cost and safety problems to transportation and hoisting; (2) Embedded parts and post-cast concrete parts need to be laid during the prefabrication process, To form the pier as a whole, the connection structure is complex, and the mechanical performance and overall performance of the entire pier are not good
