Prestress connecting device of railway prefabricated assembly type bridge pier
The invention discloses a prestress connecting device of a railway prefabricated assembly type pier, and particularly relates to a prestress connecting device which is characterized in that a prestress steel bar is anchored to a pier foundation in advance, penetrates through a prestress hole channel of a prefabricated pier and a prestress hole channel of a prefabricated cross beam, is reserved in a tensioning notch of the prefabricated cross beam and applies prestress by tensioning a prestress steel strand; and finally, pressure drop and anchor sealing are conducted on the prestressed pipeline, and connection of the prefabricated assembly type bridge piers is completed. The prestress connecting device of the railway prefabricated pier is a connecting anchoring system, effectively achieves connection of a foundation, a pier body and a cross beam, eliminates cracks at splicing joints by applying prestress, and guarantees durability and normal use of the pier.
本发明公开了一种铁路预制装配式桥墩的预应力连接装置，具体地说涉及一种将预应力钢筋预先锚固于桥墩基础、穿过预制桥墩及预制横梁的预应力孔道，于预制横梁预留张拉槽口通过张拉预应力钢绞线施加预应力，最后进行预应力管道压降，封锚，完成预制装配式桥墩连接的装置，属于桥涵工程技术领域。铁路预制装配式桥墩的预应力连接装置是一种连接锚固体系，有效地实现了基础、桥墩墩身及横梁的连接，并通过施加预应力消除了拼装接缝处的裂缝，保证了桥墩的耐久性和正常使用。
