Supporting cover beam reinforced cantilever bridge damaged bracket structure and construction method thereof
The invention discloses a supporting cover beam reinforced cantilever bridge damaged bracket structure and a construction method of the structure and relates to the technical field of bridge reinforcing construction. A rigid-flexible connecting layer for bearing the load of a damaged bracket is arranged between a steel support cover beam and the bottom of the damaged bracket beam; the construction method comprises steps that a steel supporting cover beam bottom plate, a steel supporting cover beam middle web plate, a steel supporting cover beam inner transverse partition plate, a steel supporting cover beam outer transverse partition plate and a steel supporting cover beam top plate of the steel supporting cover beam are assembled and welded, and a bearing part is formed; a pebble concrete cushion layer is poured; and injection molding of an epoxy resin mortar layer is carried out. According to the method, the damaged bracket of a bridge is reinforced unilaterally, the economical and feasible damaged bracket of the bridge is reinforced unilaterally to achieve the reinforcing effect, parts are light in weight and small in size, only a crane needs to be used for installation, erecting of a support and unloading of a jack are avoided, and traffic closing is avoided.
一种支撑盖梁加固悬臂桥梁受损牛腿结构及其施工方法，涉及桥梁加固施工技术领域，包括固定设置在最靠近所述受损牛腿的桥柱上的钢支撑盖梁，所述钢支撑盖梁与所述受损牛腿梁底之间设置有用于承受所述受损牛腿载荷的刚柔连接层，所述施工方法包括将钢支撑盖梁的钢支撑盖梁底板、钢支撑盖梁中腹板、钢支撑盖梁内横隔板、钢支撑盖梁外横隔板、钢支撑盖梁顶板组装焊接作业，形成承接部；小石子混凝土垫层浇筑；环氧树脂砂浆层注入成型；铲除封边胶，本发明采用单侧加固桥梁受损牛腿，采用经济可行的单侧加固桥梁受损牛腿达到加固效果，部件重量小、尺寸小只需要使用吊机进行安装，避免搭设支架、千斤顶卸荷，避免了封闭交通。
