Abstract
A method is disclosed for constructing, verifying, and maintaining underground vaults that isolate and contain radioactive burial sites. The method employs a buoyant lift technique to isolate a block of soil containing the contaminates from the surrounding soil. An impermeable synthetic liner is embedded in the vault to enhance the integrity of the system. The integrity of the vault is monitored by a system of sensors placed both inside and outside of the sealed vault. The method eliminates the need to excavate or drill in the contaminated areas.
Claims2
A method for constructing a subterranean containment structure, comprising the steps of:
- (a) placing a pipe having at least one port formed therein in a subterranean site to be contained;
- (b) pumping a molten wax under pressure through the at least one port in the pipe disposed in the subterranean site to be contained while said pipe is moved and rotated so that subterranean materials proximal to the pipe are impacted by the molten wax;
- (c) relocating the pipe to areas adjacent to the subterranean site;
- and
- (d) repeating steps (a) through (c) until the subterranean site to be contained is saturated with the molten wax.
