Abstract
The anchoring device of the invention is one which buries itself vertically nto the water bed material. In its common form the anchoring device is of generally cylindrical form and includes a centrally located suction passageway and fluidizing water outlets located in the general region of the lower open end of the suction passageway whereby in use and with suction applied to the suction passageway and fluidizing water made available through the fluidizing water outlets the bed material from immediately beneath the anchoring device is pumped through the body of the anchoring device and discharged above it.
Claims19
A deep burying anchoring device for providing an anchorage in the bed of a volume of water comprising
- a body member including an open-ended cylindrical
- skirt portion,
- a conical portion mounted coaxially within the skirt portion in an inverted state with its apex extending downwardly,
- a suction passageway extending at least part way through the body member and having an open lower end extending through the apex of the conical portion, and fluidising water outlet means located in the region of the base of the conical portion and shielded within the skirt portion whereby in use, and with suction applied to the suction passageway and fluidising water made available through the outlet means, a mixture of bed material/water from immediately below the body member is drawn up the suction passageway and discharged above the body member whereby the body member will bury and continue to bury itself deeper into the water bed material.
A deep burying anchoring device for providing an anchorage in the bed of a volume of water comprising
- a body member including an open ended cylindrical skirt portion,
- a conical portion mounted coaxially within the skirt portion and with the apex region of the conical portion extending below the open end of the skirt portion,
- a suction passageway located along the axis of the skirt and conical portions and extending through the apex region of the conical portion,
- fluidising water passageways arranged circumferentially around the suction passageway and having their lower ends extending through the wall of the conical portion into the space bounded by the skirt and the conical portions whereby in use and with suction applied to the suction passageway a mixture of bed material/water from immediately below and within the skirt portion is drawn up the suction passageway and discharged over and above the anchoring device, necessary fluidising water for the efficient continued operation of the device being provided to the bed material via the fluidising water passageways.
A deep burying anchoring device for providing an anchorage in the bed of a volume of water comprising:
- a body member including a conical portion,
- a suction passageway extending at least part way through the body member and including an open lower end extending through the apex of the conical portion, and
- fluidising water outlet means in the form of a toroidal ring located around the base of the conical portion and having a series of apertures in the inner circumferential region through which in use fluidising water can be directed into the general region of the lower open end of the suction passageway.
A deep burying anchoring device for providing an anchorage in the bed of a volume of water comprising:
- a body member comprising essentially a platform portion and depending therefrom a cylindrical skirt portion,
- at least one suction passageway extending at least part way through the body member and including an open lower end,
- means for providing suction in the suction passageway, and
- fluidising water outlet means located beneath the body member and positioned coaxially with the lower open end of the suction passageway such that in use fluidising water made available through the outlet means acts to fluidise the bed material immediately below the body member to enable it to be transferred, through the suction passageway as solids in suspension in water, from below the body member and discharged above the body member whereby the body member will bury and continue to bury itself deeper into the water bed material.
