金刚石钻切技术在超高层建筑拆除工程中的应用

Application of diamond drilling and cutting technology in super high-rise building demolition projects

摘要:

随着我国建筑业的飞速发展，一些存在安全隐患或不满足功能要求的超高层建筑需要拆除，如果项目位于城市中心地带，目前传统的拆除施工方法（如：机械拆除、爆破拆除）很难满足绿色环保及对保留结构保护性拆除施工的要求。天津某项目4栋＞100 m的超高层建筑需拆除重建，采用金刚石工具（绳锯和薄壁钻）钻切技术方法进行拆除，完全克服了传统拆除方法存在的诸多弊端，充分展现了金刚石钻切技术高效、安全、环保、节能、无损性方面的优势，圆满完成施工任务，得到了业主及外界一致认可，其中相关的关键技术成果可为类似超高层建筑拆除施工提供参考依据。

Abstract:

With the rapid development of China’s construction industry， some super high-rise buildings with potential safety hazards or failure to meet functional requirements need to be demolished. If such projects are located in urban central areas， traditional demolition methods （such as mechanical demolition and blasting demolition） can hardly meet the requirements of green environmental protection and protective demolition of retained structures. A project in Tianjin involves the demolition and reconstruction of 4 super high-rise buildings over 100 meters in height. The diamond tool （wire saw and thin-walled drill） drilling and cutting technology was adopted for the demolition， which completely overcame the drawbacks of traditional demolition methods. It fully demonstrated the advantages of diamond drilling and cutting technology in terms of high efficiency， safety， environmental protection， energy saving， and non-destructiveness， successfully completing the construction task and gaining unanimous recognition from the owner and the public. The relevant key technical achievements can provide a reference for similar super high-rise building demolition projects.
