STABILISATION OF ERODIBLE MARINE OR FLUVIATILE SEDIMENTS

摘要

An erodible marine or fluviatile sediment such as a sedimentary layer is stabilised by depositing on the sediment a non-setting paste-like slurry, for example, mud or clay containing stones or gravel, using a laying head which is towed over the sea bed by a surface vessel. The slurry is mixed on the vessel and conveyed to the laying head through an underwater pipe. Distribution of the slurry from the laying head may be monitored by a television camera on the head.
