ABSTRACT:
Segmented fluidization of underwater subsoils in a manner resembling peristalsis. An array of underwater locations is selected, and water is injected into the subsoil, preferably in a pattern of sequence and duration to generate lateral flow of fluidized subsoil. Apparatus for practicing such method includes a water supply pipe, multiple water-jetting branch tubes interconnected to respective segments of the supply pipe, each such branch tube being individually valved at its junction thereto. Valve-control apparatus is provided to open and close the respective valves at given times and for given durations, as by pre-programming, or optionally controlled according to resulting flow and/or pressure monitored by nearby sensors.
