Anti-collision fabricated UHPC side girder structure and construction method thereof
The invention discloses an anti-collision assembly type UHPC side girder structure which comprises two prefabricated UHPC side girders and a prefabricated UHPC bridge deck slab, the two prefabricated UHPC side girders are symmetrically distributed on the two sides of the prefabricated UHPC bridge deck slab, and a plurality of prefabricated UHPC cross beams which are spaced and parallel are arranged in the prefabricated UHPC bridge deck slab. The bottoms of the prefabricated UHPC side girders, the ends of the prefabricated UHPC cross beams and the sides of the prefabricated UHPC bridge deck slabs are connected into a whole through post-cast strips; a cast-in-place bridge deck formed by pouring common concrete is arranged on the prefabricated UHPC bridge deck. The invention further discloses a construction method of the anti-collision fabricated UHPC side girder structure. The invention has the following beneficial effects: the side main beam is prefabricated by UHPC, has the advantages of small size, light dead weight, high strength, convenient construction and the like, has good operability, can improve the durability of the side main beam, and reduces the later operation cost; the polyamide plate is arranged on the inner side, energy generated by external force collision can be absorbed, and the problem that a bridge collapses due to the fact that the road side girder is collided by external force in the operation process can be solved.
本发明公开了一种可防撞的装配式UHPC边主梁结构，包括两个预制UHPC边主梁和预制UHPC桥面板，两个预制UHPC边主梁对称分布于预制UHPC桥面板的两侧，预制UHPC桥面板内设若干间隔且平行的预制UHPC横梁，预制UHPC边主梁底部、预制UHPC横梁端部和预制UHPC桥面板侧部通过后浇带连接于一体；所述预制UHPC桥面板上设有由普通混凝土浇筑而成的现浇桥面板。本发明还公开了一种可防撞的装配式UHPC边主梁结构施工方法。本发明的有益效果为：边主梁采用UHPC预制，具有尺寸小、自重小、强度高、施工方便等优点，同时具有良好的操作性，也可改善边主梁的耐久性能，减少后期运营费用；内侧设置有聚酰胺板，能吸收外力冲撞产生的能量，可解决公路边主梁在运营过程中被外力撞击而引起桥梁坍塌的问题。
