A hydraulic manifold may be used with a dredge. The hydraulic manifold may have a body with a mounting surface, a front surface located opposite the mounting surface, a top surface located between the mounting and front surfaces, a bottom surface located opposite the top surface, and end surfaces located opposite each other and connecting the mounting, front, top, and bottom surfaces. The manifold may also have at least one drain port and at least one supply port in at least one of the end surfaces, at least one valve port in the top surface, at least one consumer port in the top surface, and at least one transponder port in the bottom surface.

A vessel (1) includes a spud (10), a spud lifting device (20) and a plurality of spud guiders (30). The spud guiders (30) are arranged to hold the spud (10) in a substantial vertical orientation and guide the spud (10) when moving in a substantial vertical direction between a lower position in which it can engage with a water bottom and an upper position. The spud lifting device (20) is arranged to lift the spud (10) from the lower position to the upper position. The vessel (1) further includes a spud position detector (40) to detect passage of the lower end (11) of the spud (10) along one or more spud detection points at predetermined heights.

A vessel includes a floating body (1), an excavating device (3) having a base member (4), an extendable arm member (5) which at one end thereof is coupled with the base member and an excavating element (6) mounted at the other end of the extendable arm member. The excavating device (3) is rotatably coupled with the floating body (1) for rotation of the excavating device in an excavator rotating area. Via an anchoring system coupled with the vessel for anchoring the floating body (1) and having a number of spuds (7, 8), the vessel may be anchored with respect to the bottom at the location to be excavated. At least one of the number of spuds (7) is a divisible spud including a plurality of spud sections (8) coupled end to end in series.
摘要:
A dredge propulsion system mounted on the same boom as the cutter head. The propulsion system has one or more augers which can be operated individually to maneuver the dredge. In the preferred embodiment a pair of augers are mounted parallel to one another on a subframe which is connected to the boom of the cutter head. The subframe comprises a first member pivotally attached to the boom. Each auger is carried by a three bar linkage mounted to the first member.

A system for transporting material recovered in a dredging operation performed by a dredge is disclosed. The system includes a water-borne material distribution vessel including a conveyor system for receiving and depositing the recovered material. It also includes at least one water-borne material transportation vessel for transporting recovered material from the dredge to the material distribution vessel. The water-borne material distribution vessel can deposit the material into the waterway to form an island (which may be a levy), into another water-borne vessel, or into an on-shore station such as a wheeled transportation vehicle.
摘要:
A dredge including a V-shaped or U-shaped pontoon having a first leg and a second leg. The legs have effective longitudinal axes that diverge from one another by an angle of no more than 180.degree.. Spuds or similar anchoring devices are connected to each of the respective pontoon legs by slides that allow the pontoon to be advanced relative to a substrate to which the spuds are anchored. A bucket wheel is suspended from the pontoon by a dredge ladder. A slewing device is provided to cause the dredge ladder, and the bucket wheel attached to it, to be slewed from side to side relative to the legs of the pontoon, about a substantially vertical axis.

A hybrid dredging apparatus uses a clamshell attached to a rigid boom to dig and remove material. The clamshell then deposits the material into the hopper of a positive displacement pump for discharge at low velocities and with minimal water content. Transducers are be used to determine and control the area of excavation.

Salt mushroom cutting apparatus for removing salt mushrooms from a water body, comprises a vessel floatable on the water body, and a helical cutter carried by the vessel forwardly of its bow and extending transversely thereof for pulverizing the salt bodies as the vessel is propelled forwardly through the water body. The helical cutter is wider than the vessel and includes a drum rotated about its longitudinal axis, and a helical array of cutter tips projecting from the outer surface of the drum. The propelling means includes at least one pair of spuds on the opposite sides of the vessel, a vertical drive for lowering the spuds into the water bed, and a horizontal drive for driving the vessel forwardly with respect to the spuds when anchored in the water bed.
摘要:
An improved method for dredging by means of a pair of spuds provided on the respective sides of the stern of a dredger and adapted to be alternately driven into the bottom of the water, a ladder projected from the bow portion of the dredger and a suction port member that is mounted at the extreme end portion of the ladder. The improvements are in the repetitive cycles of operation, each consisting of the steps of at first dredging while the suction port member is successively retracted from the foremost position of its stroke to the rearmost position as the ladder is swinging from one side towards the other about the spud on the other side, then driving the spud on the one side and retracting of the spud on the other side, advancing the suction port member to the middle position in its stroke, thereafter dredging as the ladder is swinging towards the one side, then advancing the suction port member to the foremost position of its stroke, and thereafter again dredging as the ladder is swinging from one side towards the other side. Preferable structures of a dredging apparatus to be used in the above method are also disclosed.

A stowable agitation trenching apparatus for use on a vessel such as a dredge or barge includes an adjustable, vertically extendable and retractable elongate leg slidably disposed within a mounting bracket pivotally secured to the vessel for selectively disposing a distal end of the leg at a plurality of positions underneath the vessel. An agitation producing propeller is disposed adjacent to the distal end and is movable therewith for producing an eroding current of water against the bottom surface of a body of water to be trenched or dug. The vertically extendable and retractable elongate leg is arranged to be raised and pivoted in the mounting for substantially horizontal stowage on the vessel.
