Abstract

318,355. Ward, F. L. July 27, 1928. Suction apparatus and processes. - Sand and gravel are excavated from subaqueous deposits by inserting a suction conduit to a sufficient depth within the mass to maintain a substantial seal around the mouth thereof and reducing the. back pressure within the conduit, whereby the material is lifted therein by the pressure of the overlying water. Jets may also be applied round the mouth of the conduit. As shown, a suction conduit A depends from the delivery pipe B and the latter contains a Venturi pipe D with a throat of a diameter equal to the internal diameter of the conduit A. Water &c. passes from a conduit F through a nozzle E to eliminate back pressure in the conduit A. Some of the water &c. passes through a pipe I and the hollow wall of the conduit A to jets C to assist in loosening the material. An inner nozzle H may be supplied with compressed air to assist the action. The conduit A may be moved laterally during operations. The delivery pipe B may have rifling J.
