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

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.
