Abstract: This article introduces the application of wire saw cutting technology in the construction of blower foundation reconstruction. Research shows that wire saw cutting technology is a new type of static demolition construction method. Compared with traditional gun removal methods, wire saw static cutting technology It can effectively reduce vibration and dust during the foundation cutting process, improve construction efficiency, reduce construction time, and has no impact on the running fan during the whole construction process, so it has the characteristics of environmental protection, safety, efficiency and stability, and meets the requirements of the owner.
