Bridge body reinforcing structure and construction method
The invention relates to the technical field of concrete buildings, and discloses a bridge beam body reinforcing structure and a construction method.The bridge beam body reinforcing structure comprises a bridge beam body and an ultra-high-performance concrete reinforcing layer, and the ultra-high-performance concrete reinforcing layer is composed of an ultra-high-performance concrete prefabricated formwork, a reinforcement cage, embedded steel bars and quick-hardening ultra-high-performance concrete; the steel reinforcement cage and the embedded steel bars are prefabricated on the inner side face of the ultra-high-performance concrete prefabricated formwork, and embedded steel bar holes with the hole depth smaller than the height of the side formwork part of the prefabricated formwork and the hole diameter larger than the diameter of the embedded steel bars are drilled in the bottom of the bridge body. The rapid hardening type ultra-high performance concrete is poured and filled between the ultra-high performance concrete prefabricated formwork and the bridge body and is poured and filled into the embedded steel bar holes; the composite material has extremely high strength and excellent durability and fire resistance, can be widely applied to various environments, does not influence the appearance and clearance of a bridge body, has high reinforcing strength, is convenient and rapid to construct, and can greatly enhance the strength of the bridge body and prolong the service life of an engineering structure; the construction method is simple, convenient and high in efficiency.
本发明涉及混凝土建筑技术领域，公开了一种桥梁梁体加固结构及施工方法，桥梁梁体加固结构包括桥梁梁体和超高性能混凝土加固层，超高性能混凝土加固层由超高性能混凝土预制模板、钢筋笼、植筋及快硬型超高性能混凝土组成，钢筋笼及植筋预制于超高性能混凝土预制模板内侧面，桥梁梁体的梁底钻有孔深小于预制模板的侧模部高度、孔径大于植筋直径的植筋孔，快硬型超高性能混凝土浇筑填充于超高性能混凝土预制模板和桥梁梁体之间并灌入填充于植筋孔，具有极高强度、耐久性能与耐火性能优良、可广泛适用于多种环境中、不影响梁体外观及净空且加固强度高、施工方便快速、能够极大增强桥梁梁体强度、延长工程结构服役寿命；施工方法简单方便、效率高。
