Abstract
An erodible marine or fluviatile sediment such as a sedimentary layer is stabilized by depositing on the sediment a non-setting paste-like slurry, for example, mud or clay containing a framework of 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.
Claims14
A method of stabilizing an erodible marine or fluviatile sediment comprising the steps of depositing directly over the sediment to be stabilized a slurry comprising a framework of rigid particles greater than 2 mm. least dimension and less than 100 cm. least dimension in generally touching relation and a non-setting paste-like or colloidal matrix material filling voids between particles of said framework.
