The invention discloses a demolition construction method of an existing over-crossing river channel prestressed concrete bridge, and the demolition construction method of the existing over-crossing river channel prestressed concrete bridge can ensure the safety and effectiveness of demolition work by performing windowing inspection on the existing bridge and evaluating the arrangement and failure conditions of internal steel strands. According to the demolition construction method for the existing overpass river channel prestressed concrete bridge, potential risk points can be recognized, accurate data support is provided for subsequent demolition work, an accurate demolition construction scheme is formulated through detailed stress calculation and analysis, in this way, the safety of the demolition work is improved, and the demolition efficiency of the existing overpass river channel prestressed concrete bridge is improved. According to the dismantling construction method of the existing overpass river channel prestressed concrete bridge, island construction and cofferdam construction are conducted on the two sides of the bridge, a stable construction platform is formed, a water area is effectively isolated, the river channel environment is protected, and meanwhile a guarantee is provided for safe operation of large mechanical equipment.
本发明公开了一种既有上跨河道预应力混凝土桥梁的拆除施工方法，该既有上跨河道预应力混凝土桥梁的拆除施工方法通过对既有桥梁进行开窗检查，评估内部钢绞线的布置和失效情况，能够确保拆除工作的安全性和有效性，有助于识别潜在的风险点，为后续的拆除工作提供准确的数据支持，该既有上跨河道预应力混凝土桥梁的拆除施工方法通过详细的受力计算和分析，制定了精确的拆除施工方案，这样不仅提高了拆除工作的安全性，还确保了施工过程的高效性，该既有上跨河道预应力混凝土桥梁的拆除施工方法过在桥梁两侧筑岛围堰，形成稳定的施工平台，有效地隔离了水域，保护了河道环境，同时也为大型机械设备的安全运行提供了保障。
