If earlier old concrete structures simply exploded, then the new technology completely excludes the use of explosives. Its function is performed by a powerful electric discharge, which is transferred to the environment to be destroyed through a liquid. Now scientists are trying to use polyethylene for this purpose, as the most efficient energy converter.
Under the action of the discharge, strong materials begin to break down in an absolutely safe regime. This will save the builders of the tunnel from the need to temporarily stop the work, which is typical for “explosive” technology.
Specialists from Tomsk have created for this compact, inexpensive mobile installation, the merits of which are currently being studied by employees of the West Siberian Railway .
