Description

[0002] The prefabricated assembly technology of bridge superstructure in China is relatively mature, and the superstructure of small and medium span bridges basically adopts assembly construction. However, the current prefabricated assembly pier is basically applied to lower piers, and is less applied to high piers, mainly because the joint structure is complex or the construction is difficult, the prefabricated segment height is generally large, the prefabricated segment weight is large, and it is not convenient for transportation and installation, especially for high pier bridges in mountainous areas. Most prefabricated piers use dry joints or cement joints, grouting sleeve connecting steel bar technology, which requires accurate docking of segments, matching of segments, high construction requirements, especially for high pier body verticality control, and the large amount of grouting sleeve also increases the project cost. In addition, some prefabricated piers use cast-in-place wet joint connection technology, which eliminates the need for steel bar connection and facilitates the adjustment of pier body verticality, but the steel bars in the wet joint are arranged in a staggered manner, relying on the adhesion of cast-in-place joint material and steel bars to realize the continuous stress of the pier body, and the stress performance of the joint is relatively poor. For high piers, the stress is large, the number of joints is large, the stress reliability of the pier body is reduced by using the joint technology, and in addition, the wet joint relies on adhesion to transmit force, so the height of the wet joint is generally large, the amount of material is large, and the project cost is increased.
