Construction process of multi-span integrally-prefabricated capping-beam-free pile-slab bridge
The invention discloses a construction process of a multi-span integral prefabricated capping-beam-free pile slab bridge, which comprises the following steps: (1) a pi-shaped prefabricated beam is prefabricated, the pi-shaped prefabricated beam is of an integral prefabricated structure and comprises a top plate, at least three main beams and beam ribs, the main beams and the beam ribs are positioned on the bottom surface of the top plate, and each main beam corresponds to stand columns arranged in rows; (2) the stand columns are installed according to the design scheme, (3) the pi-shaped precast beams are conveyed to a construction site and hoisted in place, structural joints are formed between the adjacent pi-shaped precast beams arranged in the longitudinal direction of the bridge, and the structural joints are arranged in the longitudinal direction of the bridge. Then concrete longitudinal wet joints are poured between the adjacent pi-shaped precast beams arranged in the transverse direction of the bridge, and concrete is poured on the tops of the pi-shaped precast beams to form a concrete cast-in-place laminated layer (4); and bridge ancillary facilities and a bridge deck structure are constructed. No bent cap and no cast-in-place cross beam are arranged, the cast-in-place project amount is greatly reduced, the project quality is guaranteed, and the bridge forming efficiency is improved.
本发明公开了一种多跨整体预制无盖梁桩板桥梁的施工工艺，包括①预制π型预制梁，所述π型预制梁为一体化预制结构，包括顶板及位于其底面上的主梁和梁肋，主梁至少3个，每一主梁均与成排设置的立柱相对应；梁肋与主梁相互垂直，且每一梁肋均与成列设置的立柱相对应②按照设计方案安装立柱③将π型预制梁运送至施工现场，吊装就位，其中，沿桥梁纵向排列的相邻π型预制梁之间设置有结构缝，然后在沿桥梁横向设置的相邻π型预制梁之间浇注混凝土纵向湿接缝，在π型预制梁的顶部浇筑混凝土形成混凝土现浇叠合层④施工桥梁附属设施和桥面结构。本发明无盖梁、无现浇横梁，现场浇筑工程量大幅降低，既保证了工程质量，又提高了成桥效率。
