Concrete bridge reinforcing structure and construction method
The invention relates to the technical field of bridge reinforcing, and discloses a concrete bridge reinforcing structure and a construction method.The concrete bridge reinforcing structure comprises a cover beam body and a hollow slab beam located above the cover beam body, an upper reinforcing system is arranged at the bottom of the hollow slab beam, and a lower reinforcing system is arranged at the bottom of the cover beam body; a plurality of web plates are arranged in the hollow slab beam, the upper reinforcing system comprises longitudinal reinforcing pieces fixedly connected to the bottom of the hollow slab beam, and the longitudinal reinforcing pieces and the web plates are equal in number and arranged in a one-to-one correspondence mode; the lower reinforcing system comprises side face reinforcing parts on the two sides and a bottom face reinforcing part, and the bottom face reinforcing part and the side face reinforcing parts on the two sides are connected into a whole. Prestress systems are arranged in the side face reinforcing parts on the two sides of the cover beam body and symmetrically arranged in the side face reinforcing parts along the center line of the cover beam body. By arranging the upper reinforcing system and the lower reinforcing system, the problem that in the prior art, a common reinforcing mode cannot meet the requirement for high bearing performance after bridge transformation is solved.
本发明涉及桥梁加固技术领域，公开了一种混凝土桥梁加固结构及施工方法，包括盖梁本体和位于盖梁本体上方的空心板梁，空心板梁的底部设有上加固系统，盖梁本体的底部设有下加固系统；空心板梁内设有若干个腹板，上加固系统包括固定连接于空心板梁底部的纵向加强件，纵向加强件的数量与腹板数量相等且一一对应设置；下加固系统包括两侧的侧面加固部和底面加固部，底面加固部与两侧的侧面加固部连为一体；盖梁本体两侧的侧面加固部内设有预应力系统，预应力系统沿着盖梁本体中心线对称地设置于侧面加固部内。本发明专利中通过设置上加固系统和下加固系统，解决了现有技术中采用普通加固方式无法满足桥梁改造后较高承载性能需求的问题。
