ABSTRACT:
Vertical prefabricated drains are installed into soil underlying a body of water for soil stabilization and thereafter from the surface of the water the drain member is captured within a drain cutting assembly which is lowered by an operating line that is tethered to the assembly into the water as guided by the captured drain. Then the prefabricated drain is severed below the surface of the water by actuating the cutter assembly at the water surface with the operating line.
