摘要
近年来,随着城市飞速发展,市政路网规划更新调整周期也不断缩短,随之而来的老桥拆除重建工作也进入了近几年的多数城市市政工程的实施清单中。从当前老桥拆除施工技术现状出发,结合笔者近期参与管理实施的沿海某市老桥拆除施工的实际工作,通过综合比较,最终确定"支架+绳锯分块切割吊装拆除"的方案,并予以实施,达到预期效果。
In recent years,with the rapid development of city,the renewal and adjustment period of municipal road network planning are continuously shortened,and the accompanying demolition and reconstruction of old bridges are also listed in the implementation bill of municipal engineering in many cities.Starting from the present demolition construction technology of old bridge,according to the management and implementation of the demolition construction practices of old bridges in a city,and after comprehensive comparison,the scheme of 'bracket+rope sawing block cutting hoisting demolition' is finally determined,and is implemented to achieve the expected effect.
