It is a method for cutting and dismantling concrete and other structures underwater for removal.
The completely wet-type underwater wire saw method is a technique for cutting and removing structures such as concrete underwater during demolition. It allows for space-saving operations at great depths and is not affected by working depth (working depth from 0m to 45m). Since the wire saw machine is entirely installed underwater, there are no human-related accidents, and because the cutting machine itself is underwater, operations can continue even if the work vessel is swaying. It can be constructed with a minimal length of diamond wire for cutting, and due to the compact size of the machine, CO2 emissions are significantly reduced. 【Features】 - Equipment can be loaded onto a small vessel for preliminary cutting. - Monitoring is done via surveillance cameras, allowing for immediate response to any issues. - Biodegradable oil (ISO 6743 Class L) is used for operational fluids. - NETIS registration number KKK-090001-A (registration period has ended).
