Construction method of full-prefabricated assembly type pre-tensioning method prestressed pi beam pile slab bridge
The invention relates to a construction method of a full-prefabricated assembly type pre-tensioning method prestress pi beam pile slab bridge. The construction method comprises the following steps that a temporary hoop system is installed; s2, a temporary auxiliary positioning support system is installed; s3, a pipe pile core grouting reinforcement cage is installed; s4, secondary installation of the temporary auxiliary positioning support system; s5, the prefabricated bent cap is hoisted in place; and S6, prefabricated pi-beam hoisting and post-cast strip wet connection operation are carried out. The construction method of the full-prefabricated pre-tensioned prestressed Pi-shaped beam pile slab bridge is high in hoisting and positioning speed, high in operation efficiency and simple and convenient in construction operation, has the construction advantages of high quality, high efficiency, high benefit and the like during implementation, and is remarkable in technical benefit.
本发明涉及一种全预制装配式先张法预应力π梁桩板桥施工方法，包括以下步骤：临时抱箍体系安装；S2、临时辅助落位支架体系安装；S3、管桩灌芯钢筋笼安装；S4、临时辅助落位支架体系二次安装；S5、预制盖梁吊装就位；S6、预制π梁吊装及后浇带湿接作业。本发明所涉及的全预制装配式先张法预应力π梁桩板桥施工方法，吊装定位速度快，作业效率高，施工操作简便，实施时具有高质量、高效率、高效益等诸多施工优势，技术效益显著。
