摘要： A settling unit for separating a liquid and the particles. Such as sand, suspended therein, comprises a basin with an inlet for the liquid mixture containing the particles, and an overflow for discharging the liquid after at least some of the particles have been removed therefrom through settling. With a view to increasing the efficiency, a plate separator is provided at the position of the overflow, which plate separator has a liquid outlet which is connected to the overflow and an outlet for settled particles which is connected to the basin. The gaps defined between the plates can be shut off at their underside by a non-return valve which can be moved into an open position under the influence of the weight of the separated particles.

摘要： A padding machine (10, 100) which is capable of separating materials in a spoils bank beside a trench into coarser materials, which are redeposited in the spoils bank behind the machine, and finer materials which are conveyed to the trench for padding the pipeline. The machine includes a conveyor with a conveyor chain which moves around the perimeter of the machine. Material caught by the scraper blade (28) is conveyed by the conveyor chain along a belly pan (70) and thereafter over a plurality of grizzly bars (72). Coarser material which will not pass through the grizzly bars is conveyed by the conveyor chain (56) to the rearward end of the machine and dumped off the rearward end of the machine back to the ground. The finer materials passing through the grizzly bars are again separated by a vibrator unit (76, 104). The depth of the scraper blade can be adjusted by pivoting the entire frame about the wheels (34) at the rearward end of the frame by a hydraulic cylinder (48) pivoting the towing arm (38). A padding machine ( 120) is also disclosed which does not use a scraper blade (28), but relies on flights (88) to move material.

摘要： The invention relates to a container for the ground material removed by a ground working device, for example, a mud plough or a suction device from the bottom of a watercourse. Such a container is known in the form of a compartment trough moved by the tugboat of the mud plough or the hopper barge. A disadvantage of such a container is that it is heavy and hence transportable only with difficulty while it is expensive and cannot be emptied by a simple procedure. The invention has for its object to obviate these disadvantages and provides to this end a container of the kind set forth in the preamble constructed in the form of a flexible bag that can be connected with the ground working device.

摘要： A hopper valve module is adapted to be removably mounted in the well of a hopper of a hopper dredge vessel and includes a housing and a valve member movable with respect to the housing for opening and closing the hopper outlet. A transmitter tube containing longitudinally spaced-apart magnetic switches and associated resistors is carried by the housing, the switches being connected in circuit with resistors and coupled to power supply and indicating means in the vessel. A hollow sleeve is fixedly secured to the valve member and is disposed in surrounding telescopic relationship with the tube, the sleeve carrying a permanent magnet therein for sequentially actuating the magnetic switches as the valve member moves between its open and closed positions, the varying current through the assembly of switches and resistors indicating the position of the valve member.

摘要： Minerals or other bodies are lifted hydraulically from a region below the surface of a free fluid medium, such as the ocean. An at least partly gas-filled chamber with an elongated conduit extending therefrom is at least partially submerged in the fluid medium so that the conduit extends to the region from which the bodies are to be lifted. The fluid level in the chamber is maintained sufficiently lower than that of the surrounding fluid medium, as by a suction pump exhausting into the medium, such that the fluid pressure corresponding to the difference between the fluid level in the chamber and the level of the medium is at least substantially equal to the sum of the frictional pressure drop of fluid through the conduit and the pressure drop due to the lifting of the bodies in the fluid medium through the conduit. The velocity of fluid flow through the conduit is maintained larger than the steady state sinking velocity of the bodies.

摘要： The invention concerns an apparatus for establishing an anchorage in the of a liquid. The apparatus comprises essentially a substantially hollow structure into which solids from the liquid bed are induced as solids in liquid suspension. When the apparatus is being used as an anchoring device the design is such that as solids from the liquid bed are induced into the substantially hollow structure they fill or partially fill the structure which then proceeds to bury itself into the liquid bed thereby establishing an anchorage.

摘要： Dredging or suction of a soil suspension from the sea bottom is effected through a suction conduit connected with a suction head enclosure resting on the sea bottom, there concurrently being supplied to the suction head enclosure and through a separate conduit connected therewith a transport fluid under pressure. Transport fluid is separated from the soil suspension collected at the surface and recycled to the suction head enclosure. Thus the transport fluid flows in a substantially closed recirculating flow course and consequently pollution of the sea is lessened.

摘要： A system of subaqueous excavation and material removal having the combination of a hopper dredging vessel, hopper barges with independent dumping capacity and a prime mover vessel such as a tug, each barge having a stern notch and a bow portion which is contoured to be received in a like stern notch of an adjacent barge so that two or more barges can be arranged in an assemblage, end-to-end with bow portions fitting into the stern notches. The dredging vessel and prime mover vessel also have like bow portions whereby they can connect into the assemblage. By transporting filled assemblages from the dredging vessel for dumping and replacing same by empty assemblages the dredging vessel may continue its operation on practically a 24 hour basis. Rapid and effective securing of the assemblage, the dredging vessel and prime mover vessel are obtained through pneumatic fenders attached to the sides of the stern notches and a pneumatically controlled cushioning fender couple attached to the stem which is received between vertical expansible fenders at the apex of the stern notch. By expansion of the fender couple and the apex fenders the vessel is effectively secured to the assemblage. In order to separate the assemblage and the vessel, the fender couple and the tubular members are deflated. Conduits to carry dredged material are located on each barge and the dredging vessel. Each has a tubular outlet extending proximate the bow portion which is received in a larger tubular inlet extending proximate the stern notch, there being an arrangement of annular members about the engaging conduit means which are expansible and securely connect the conduits together whereby dredged material may be delivered from the dredging vessel simultaneously to each of the barges in the assemblage. The connection of the units is accomplished without any rigid structural linkage over a relatively broad and large surface to surface area whereby unwanted redundancy of strength at the connection is largely eliminated.

摘要： A hopper craft is adapted to be loaded with relatively light material such as mud or with relatively dense material such as mixtures of sand and gravel. A central hopper is provided with air chambers on either side, and loading means selectively direct the load into the central hopper and/or the air chambers. The central hopper overflows into the air chambers and the air chambers overflow to the sea; while alternatively, the central hopper can overflow directly to the sea. The central chambers are used for any type of material but the air chambers are used only for light material.
