碟式切割机在拆卸钢筋混凝土桥梁中的应用

Application of Dished Cutter in Demolishing of Reinforced Concrete Bridge

广州市广武人行天桥拆除工程,地处交通繁忙、人流密集地带,受多方条件限制,无法采用传统方法拆卸。施工单位根据天桥的结构形式和起吊设备的起吊能力,制定详细的实施方案,采用水冷却金刚石碟式切割机拆卸取得成功。作业面小、速度快、效率高,对周围环境影响小,施工过程安全可靠。对其它类似钢筋混凝土桥梁拆卸工程具有参考价值。

As it's located at a crowded zone with heavy traffic and several restricted conditions, the Guangwu pedestrian overpass in Guangzhou could not be demolished with conventional method. The construction contractor made a detailed plan in accordance with the structural type of overpass and hoisting ability of crane. The demolish work was carried out successfully by a water-cooled diamond dished cutter with smaller operational scope, faster speed, higher efficiency, smaller interference with the surroundings and safe & reliable construction course, for reference of similar demolish works of reinforced concrete bridge.
