It is difficult to ensure, and the generally existing serious corrosion phenomenon of concrete pier of built bridge spanning the sea.It is some over strait big thus
Bridge also uses bridge pier precast segment assembling construction, mostly uses total cross-section precast assembly, but this erection method lifting weight is very
Greatly, heavy mechanical equipment is needed, and connector splicing seams mostly use mortar, horizontal shear strength is weaker.
Ultra-high performance concrete (Ultra-HighPerformance Concrete, UHPC), due to its resistance to corrosion
By force, gradually it is applied to bridge spanning the sea etc. in recent years in compared on the bridge in adverse circumstances, application No. is
201711028881.8 Chinese patent discloses the construction and the practice of a kind of connection of precast assembly bridge pier segment, the connection structure
Make the precast assembly steel pipe encased concrete bridge to connect based on ultra-high performance concrete (UHPC), inner sleeve joint steel pipe with high-strength bolt
Pier；UHPC is applied between precast pier segment in connection, takes full advantage of the resistance to compression and tensile property of UHPC brilliance, thus
Solve the problems, such as that the connection of precast pier segment is weak.But in the structure, the shrinkage of cast-in-place UHPC connector is larger, with prefabricated portion
The concrete divided may be detached from faying face；The used structure that UHPC is poured from horizontal direction, UHPC's is closely knit
Degree is difficult to ensure；Prefabricated subsection self weight is larger, constructs difficult；Steel exposure in air, needs periodically to derust, the later period
Maintenance cost is big.
