Zusammenfassung: | Reactive gabion/geocomposite articles, and their methods of manufacture, fo r controlling contaminants in soil, sediment or water that allow the passage o f essentially non-contaminated water therethrough. The articles and methods described here in utilize gabions, which are box shaped cages or grids (see Fig. 2) made of either ste el wire mesh or plastic. In one embodiment, the reactive geotextile mats are lined on the to p major surface with a gabion cage or grid. In other embodiments, the cages or grids surroun d a geocomposite containing reactive material. The gabion/geocomposite articles can be constructed in-situ (at the site of deployment) or remotely (on land or barg e) and set in place. They are typically placed side-by-side and, in a preferred embodiment, are configured to cover a target sediment area, underwater. The gabion/geocomposite articles m ay be filled with clean sediment, silt, sand and/or concrete block or rock to hold the reactive geocomposite in place and for armoring. |
