摘要： A method and apparatus for digging and removing excavated material from a selected site provides a mobile device having a chassis that is movable or self-propelled. The mobile device has an elongated, preferably articulated boom with a free end portion having a digging implement that can include a digging tool, excavating tool or jetting tool. The boom preferably comprises at least three sections. The boom sections are foldable to a storage position on the chassis wherein one boom section stacks upon or is aligned with another boom section. The vacuum line is supported upon the boom wherein the vacuum line extends between the free end portion of the boom and the chassis. The boom attaches to the chassis at a base that can include a rotary or pivotal connection. The vacuum line supported by the boom extends along the boom and above the earth's surface. A selected material is excavated with the excavating implement (e.g., jetting tool or digging tool). The excavated material is vacuumed with the vacuum line into a collection vessel or tank that can be a part of a wheeled vehicle thus enabling transport to a disposal site. A separate vacuum truck can provide a vacuum to a selected collection tank.

摘要： A pneumatic excavator for delivering pulsed compressed air includes an actuator; a controller valve; a flow valve; a barrel defining an outlet of the excavator; and a pulse control line extending between the controller valve and a port downstream from an egress of the flow valve. As compressed air flows through the egress of the flow valve, the pulse control line is pressurized and shifts the controller valve to an actuated position, causing the compressed air from the actuator to close the flow valve, thus preventing the air flow from passing through a primary flow passage and through the outlet. The pulse control line being no longer pressurized by the air flow, then causes the controller valve to move to an unactuated position to cause compressed air from the actuator open the flow valve and permit the air flow through the outlet and again pressurize the pulse control line.

摘要： A pneumatic excavator configured to be pneumatically actuated includes an actuator; a flow valve fluidly coupled to the actuator an air actuation conduit; and a barrel coupled to an egress of the flow valve, where the barrel defines an outlet of the pneumatic excavator. Actuating the actuator causes compressed air to be transmitted from the actuator through the an air actuation conduit to a first port of the flow valve to open the flow valve and compressed air from a supply of compressed air passes through the flow valve and the outlet of the pneumatic excavator. Releasing the actuator causes the compressed air to be transmitted from the actuator through the at least one air actuation conduit to a second port of the flow valve to cause the flow valve to close and the flow valve prevents the compressed air from the supply of compressed air from passing therethrough.

摘要： Mixing systems that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.

摘要： A device for the removal of a layer of sludge and/or sand from the bottom of a wetland includes: a diving bell with an open bottom and a lower free edge; a unit for driving the diving bell with its lower edge into the layer of sludge to be removed; a dredge pump installed in the space of the diving bell and provided with an inlet for pumping up the sludge and/or an outlet to which a pipe is connected for pumping the pumped up sludge and/or sand to a collector; and a compressor for pumping gas under pressure into the space of the diving bell during dredging. The diving bell is also provided with a gas outlet for the compressed gas, the gas outlet being adjustable in height in the diving bell because the outlet is attached to a float that can float on the sludge.

摘要： “There is disclosed an excavation apparatus (5), such as an underwater excavation apparatus, having means for producing, in use, at least one vortex, spiral or turbulent flow in a laminar flow of fluid, e.g. water. The excavation apparatus (5) comprises a rotor (10) having a rotor rotation axis (A), wherein, in use, flow of fluid passedpast or across the rotor (10) is at a first angle (α) from the axis of rotation (A). The excavation apparatus (5) comprises the rotor (5) and means or an arrangement for dampening reactive torque on the apparatus (5) caused by rotation of the rotor (10), in use. The turbulent flow is provided within, such as within a (transverse) cross-section, of the laminar flow.”

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.
