    摘要: A method of dredging which comprises suspending dredging apparatus 200 from a vehicle 360. The sediment agitating apparatus comprising a chassis 210, and mounted on the chassis are an extractor, sediment agitating apparatus and respective pumps 220, 230. The dredging apparatus 200 is disposed above, but not in contact with a waterbed 340 to be dredged of sediment 350. The sediment 350 is agitated then extracted with the extractor. The dredging apparatus 200 is moved around the water and the extracted sediment 400 is deposited underwater and above the dredging apparatus 200, so that the sediment 400 is transported and deposited away from an area being dredged by the natural movement of the water. Apparatus and use of the apparatus are also described.

    摘要: In order to meet the objective of providing a device (10) and a method for a sediment transfer in waters (80, 81, 90) that works efficiently, a device (10) comprising at least one suction line (12) and at least one receiving means (16) for receiving sediment (70), and furthermore, having at least one pressure line (14) for transferring the received sediment (70) is proposed. Following the at least one receiving means (16), at least one pump device (18) and at least one measuring device (20) for determining a sediment concentration of the received sediment (70) are arranged. The device (10) further comprises a control unit (22) having a first interface (25) for inputting target values (24) and a second interface (26) for the at least one measuring device (20), and determines a sediment concentration in the at least one suction line (12) and/or in the at least one pressure line (14). Depending on the sediment concentration, a power of the pumping device (18) is adjustable.

    摘要: A tilt adjustable head attachment assembly for a clamshell style bucket for orienting first and second bucket halves at an angle relative to a length axis extending through an elongated and rigid attachment associated with a piece of power equipment, for supporting and manipulating the bucket. A frame has a three dimensional body, upwardly extending pillar mounts located at upper ends of the body and incorporating support shafts for receiving overlapping hinged locations associated with support arms for each of the first and second clamshell bucket halves. A platen is positioned pivotally arranged between the pillar mounts and includes an upper location engaged by an end projection of the elongated attachment. A cylinder is connected to a fixed underside location of the frame at a first end and to the platen at a second end and, upon being actuated, pivotally displacing the platen to in turn angle the frame and supported clamshell bucket halves relative to the excavator attachment according to a desired orientation.

    摘要: A system for excavating sediment deposits from water storage reservoirs that equalizes the mass flow of sediment entering the reservoir with the sediment mass in the combined discharge from a dredge and the reservoir outlet system to the downstream water course. One or more remote instrument stations located on the inflow streams to the reservoir collect data that is used by the dredge control system to adjust the mass flow output from the dredge using data collected from the remote reservoir outlet instrumentation located downstream of the reservoir.

    摘要: A water conserving silt discharging device includes a moving bottom plate. A first material conveying water pump, a stirring box, a filler box and a compression box are sequentially arranged on an upper portion of the moving bottom plate. And a roller mechanism is arranged on each of four diagonal portions of a lower portion of the moving bottom palate. A controller, an infrared sensor and a high-definition camera assembly are arranged on the upper portion of the moving bottom plate. The first material conveying water pump conveys silt material to the stirring box through a convey pipe. A jitter mechanism assembly is arranged at a bottom portion of the stirring box to generate jittering. The jitter mechanism assembly comprises a plurality of identically shaking spring bodies and a driving cylinder arranged on the shaking spring bodies.

    摘要: A cutterhead for dredging water-bed material from a body of water. The cutterhead comprises a shroud presenting a front margin for receiving water-bed material into an interior space of the shroud. The shroud additionally includes a port from which water-bed material can be removed from the interior space of the shroud. The cutterhead additionally comprises a rotatable cutterbar at least partially received within the interior space of the shroud. The cutterhead further comprises a debris guard positioned between the cutterbar and the port. The debris guard is operable to filter the water-bed material removed from the shroud through the port. At least a portion of the debris guard that faces the cutterbar includes a concave shape.
