Method for reconstructing old bridge gate into light-weight combined bridge and light-weight combined bridge
The invention discloses a method for reconstructing an old bridge gate into a light combined bridge and the light combined bridge. The reconstruction construction of the bridge is realized through the steps of stress analysis and reinforcement of the old bridge gate, bridge abutment construction, bridge pier construction, primary and secondary beam construction, bridge frame assembly and bridge deck pavement. According to the construction method, the old abandoned bridge gate is utilized, the old abandoned bridge gate serves as the middle bridge pier after the bearing capacity of the old abandoned bridge gate is analyzed, then concrete is poured on the prefabricated key groove plate to form the light combined bridge deck, the double-span crossing arch steel structure bridge frame is arranged, and the cantilever steel structure cable frame is arranged in an auxiliary mode, so that the old bridge gate can be fully utilized, and the construction of the multifunctional bridge is achieved; and the method is green and environment-friendly, low in cost and short in construction period.
利用旧有桥闸改建为轻型组合桥的方法及轻型组合桥，通过步骤旧有桥闸受力分析加固、桥台施工、桥墩施工、主次梁施工、桥架组装、桥面铺装实现桥梁的改造施工。本发明中，利用旧有废弃桥闸，分析其承载能力后以其作为中间桥墩，然后在预制键槽板上浇筑混凝土形成轻型组合桥面，设置双跨交拱钢结构桥架，附属布置悬臂钢结构电缆架，能够充分利用旧有桥闸，实现多功能桥的建造，具有结构简单，绿色环保，成本低，工期短的特点。
