摘要： A pile hammer for driving down hollow piles from an upper end thereof includes a hollow pile cap adapted to rest and support the hammer on a upper end of the pile being driven. The cap has an anvil surface for receiving blows from a ram which is slidably disposed on a hollow tubular base extending downwardly from the pile cap and having a lower end portion extending into the hollow pile being driven below the level of the pile cap. The ram is slidable on an upper portion of the hollow tubular base and has an annular lower end face adapted to strike the anvil surface of the pile cap when the ram is released to drop from an elevated position above the pile cap. A ram lift system is provided in an upper portion of the hollow tubular base for lifting the ram to an elevated position a selected predetermined height above the pile for release to drop downwardly and strike a driving blow against the anvil surface on the pile cap. The pile hammer is supported completely on the pile being driven and other means of support are not required. Sea water may be used as the operating fluid of the pile hammer and the hammer is operable above or below the water or on dry land. The pile hammer includes a remotely controllable, fluid control system for operating the pile hammer in an automatic or manual mode and the pile hammer does not require a waterproof enclosure.

摘要： This disclosure relates to an underwater excavation apparatus comprising a tube in which a propeller is mounted for rotation. The tips of the propeller blades are formed with jets supplied from a high-pressure water supply through passages in the propeller blades. The jets impinge on vanes mounted on the tube wall around the propeller to cause the propeller to rotate and thereby draw water through the tube from a inlet at one end to an outlet at the other end to act on the seabed. The apparatus is particularly useful for excavating trenches on the seabed and exposing previously covered installations on the seabed.

摘要： An underwater hammer, of the gas discharge type, is provided with a surrounding casing arranged in the nature of a diving bell from which liquid can be purged so that the hammer ram may move up and down with minimum resistance. A reflood tube extends down through the upper end of the casing and opens into an axial reflood passageway in the ram and liquid is pumped through this tube to obtain reflooding after each cycle of operation.

摘要： An underwater gas discharge type hammer is provided with a gas reservoir into which expended ram driving gas exhausts to avoid aeration of incoming water which surrounds the gas discharge device of the hammer. The gas resevoir is also arranged as a diving bell to minimize pressure changes under the hammer ram and thereby to maximize ram stroke and improve sharpness of ram impact on the hammer anvil.

摘要： The pile-driving arrangement can drive piles both above and below water. It includes a housing containing a gas-filled motion chamber and an impact body movable upward and downward in the motion chamber. A cylinder-and-piston mover includes a cylinder part and a piston part, one part connected with the housing and the other with the impact body, for effecting relative movement between the impact body and the housing. A drive unit on the housing includes a drive motor, a pump driven by the motor and a pressure fluid tank. The drive unit is connected with the housing for limited movement relative to the housing. The cylinder part and the pressure fluid pump are interconnected by flexible conduits leading from the pump to the opposite working chambers of the cylinder part, and a direction-changing device controls fluid flow through the conduits. The drive unit is buoyant and floats above the housing at a certain distance when the pile-driving arrangement is submerged, so that shocks are not communicated directly to the drive unit.

摘要： A hydraulically driven radial inflow turbine having power takeoff means attached thereto is actuated and controlled by an axially translatable nozzle ring. A manually actuatable trigger mechanism admits a small amount of control fluid which is tapped from a primary source of liquid under pressure into a chamber defined by the nozzle ring and the turbine housing to move the nozzle ring in registering alignment with the primary liquid inlet apertures to the turbine impeller blades. The trigger assembly proportionately supplies hydraulic pressure to the turbine to control the flow of fluid to the turbine thereby controlling the power output.
