Simply supported beam bridge floor continuous structure and construction process
The invention relates to the technical field of road and bridge erection, in particular to a simply supported beam bridge deck continuous structure and a construction technology. The simply supported beam bridge floor continuous structure is provided, each simply supported beam comprises two adjacent simply supported beams, the bridge floor continuous ends of the two simply supported beams are provided with flange plates, and the flange plates are provided with reserved grooves in the advancing direction of the bridge floor; and a rubber modified pavement material is paved at the bottom of the preformed groove. UHPC is cast in the preformed groove in situ, so that the stress performance of the structure can be effectively improved, the development of displacement and concrete strain is delayed, and the development of cracks is inhibited; a rubber pad or rubber asphalt is flatly laid at the bottom of the preformed groove, so that the tensile stress distribution condition of the top surface of the continuous section can be effectively improved, cracks are delayed, and the durability of the UHPC bridge deck continuous structure is improved.
本发明涉及道桥架设技术领域，具体地涉及一种简支梁桥面连续结构及施工工艺。提供了一种简支梁桥面连续结构，所述简支梁包括相邻的两跨简支梁，两跨简支梁的桥面连续端设有翼缘板，所述翼缘板上设置有沿桥面行进方向的预留槽；所述预留槽底部铺设有橡胶改性的路面材料。在预留槽内现浇UHPC可以有效改善结构受力性能，延缓位移和混凝土应变的发展，抑制裂缝的发展；在预留槽底部平铺橡胶垫或者橡胶沥青可有效改善连续段顶面拉应力分布情况，延缓裂缝的出现，提高UHPC桥面连续结构的耐久性。
