摘要： A soft excavator (10, 90, 110, 130) is disclosed which utilizes a jet of high velocity fluid flow such as air or water flow, preferably supersonic, through a nozzle (48, 92, 112) to excavate a material, such as the ground. A second passage for air flow is provided which is directed by an evacuator skirt (52, 102) in a direction along the excavator generally opposite the direction of discharge of the high velocity excavating flow to entrain the material excavated for disposal.

摘要： Device and process for the displacement of sediment under water by means of water jets which liquify the sediment so that it flows away under water without poluting the surface water, the improvement being that the device has latterally directed outflow openings, which reach areas out of reach of the downwardly directed jets and by means of which soil accumulations such as ridges can be leveled.

摘要： Process and apparatus for enhancing the erosive intensity of a high velocity liquid jet when the jet is impacted against a surface for cutting, cleaning, drilling or otherwise acting on the surface. A preferred method comprises the steps of forming a high velocity liquid jet, oscillating the velocity of the jet at a preferred Strouhal number, and impinging the pulsed jet against a solid surface to be eroded. Typically the liquid jet is pulsed by oscillating the velocity of the jet mechanically or by hydrodynamic and acoustic interactions. The invention may be applied to enhance cavitation erosion in a cavitating liquid jet. or to modulate the velocity of a liquid jet exiting in a gas, causing it to form into discrete slugs, thereby producing an intermittent percussive effect

摘要： A method of improving surf conditions above a seabed is provided. The seabed is at least partly formed of unrestrained sediment. The method includes moving some of the sediment to form a formation of unrestrained sediment. A grooming device is provided for improving surf conditions above a seabed. The device is movable in a direction of travel along the seabed and includes an outlet and an arrangement. The outlet is for directing, in a direction transverse to the direction of travel, a stream of water to move some of the sediment. The arrangement is for engaging the seabed to resist force resultant from the directing the stream of water.

摘要： The invention relates to a dredging method for dredging a navigation channel for guaranteeing a nautical depth of a navigation channel. The method comprises performing agitation for mobilizing sediment and displacing the mobilized sediment to a collector which is embedded in the bottom of the navigation channel, the collector being a trench in the navigation channel wherein the trench has, when not being filled with sediment, a bottom level positioned substantially deeper than the nautical depth of the navigation channel. The method also comprises, in a step different from said performing agitation dredging, after solidification of the sediment collected in the collector, removing the solidified sediment from the collector so that the collector again has a bottom level positioned substantially deeper than the nautical depth of the navigation channel.

摘要： A jetting system for an undersea trencher has jetting conduits extending aftward of its trench-cutting jetting swords. Jetting conduit nozzles direct liquid radially from their jetting conduits into the trench after the trench is excavated by the jetting sword cutting nozzles. The jetting conduits direct sufficient liquid into the trench to maintain the mix of trenched soil and water in the trench along the length of the conduits at not more than a super-critical density.

摘要： A water pump control system is provided for vacuum excavation equipment. The water pump control system includes a control circuit for controlling a hydraulic actuation circuit configured to control a water pump circuit such that a water pressure produced by the water pump circuit does not exceed a desired water pressure. The hydraulic actuation circuit can include a proportional hydraulic valve, and the control circuit controls a water pump speed by monitoring a water pressure and adjusting an electric current flowing into the proportional valve to meet the desired water pressure. The control circuit can include a pressure transducer mounted to the water pump circuit to monitor the water pressure in real-time.
