    摘要: The disclosure relates to an underwater excavation apparatus comprising a tube (10) in which a propeller (18) is mounted for rotation. The tips of the propeller blades are formed with jets (30) supplied from a high pressure water supply through passages in the propeller blades. The jets impinge on vanes (31) mounted on the tube wall around the propeller to cause the propeller to rotate and thereby draw water through the tube from an 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 excavator in which when energized by a supply of hydraulic oil or other means a propeller is set in motion with water being drawn through a water intake into a cylindrical tube and expelled at the water outlet to create a flow of water of sufficient volume and velocity to blow away seabed materials. Thrust and torque are counteracted by the suction force developed at the water intake. Optional filter nets or sieves may be fixed to a foot of the machine to capture samples of the material washed out of the seabed.
