Abstract

The invention discloses a precast pier suitable for a sea-crossing bridge, which comprises a pier main body, wherein the pier main body comprises a plurality of precast pier body segments arranged along the height direction of the pier main body; the adjacent two precast pier shaft segments are connected with each other through wet joint members. The wet joint members include a plurality of pairsof U-shaped reinforcing bars, a plurality of pairs of U-shaped reinforcing bars are preset between the adjacent two precast pier shaft segments, and a plurality of pairs of U-shaped reinforcing bars are spaced apart along the length direction of the precast pier shaft segments. A plurality of ring-shaped reinforcing bars, each ring-shaped reinforcing bar corresponding to a pair of U-shaped reinforcing bars, and each pair of U-shaped reinforcing bars is fixed by a corresponding ring-shaped reinforcing bar; Each pair of U-shaped reinforcing bars is fixed by a corresponding ring-shaped reinforcing bar, a gap is left between each pair of U-shaped reinforcing bars, and the gap between each pair of U-shaped reinforcing bars is located in the corresponding ring-shaped reinforcing bar; all ring bars and all U-shaped bars form a cavity which is connected with each other, and the cavity is filled with concrete.

Description

technical field [0001] The invention relates to the field of bridge connection structure design, in particular to a prefabricated pier suitable for a sea-crossing bridge. Background technique [0002] With the construction of the country, many coastal areas have accelerated the construction of infrastructure, especially the construction of road traffic. Among them, the construction of cross-sea bridges is an important link in the construction of coastal roads. Due to the limitation of the environment, the sea-crossing bridge is different from the general inland road bridge. It usually requires a better landscape, and requires as little impact on the environment as possible before, after and during the construction. The offshore construction of the cross-sea bridge will inevitably face harsh construction environments such as strong winds, high waves, tides, and short operating hours, and has the characteristics of huge project scale, high risks, and difficult quality control....
