Method of installing a floatable pump apparatus and an anti-erosion plate in a water treatment basin

摘要

A method of installing a floatable pump apparatus and an anti-erosion plate at a selected location in a bounded water treatment basin wherein the floatable pump apparatus includes a float having a central opening therethrough and a motor and axial flow propeller-type pump. A winch is temporarily mounted on the upper side of the float and one end of the winch cable is extended downwardly through the central opening in the float and attached to the anti-erosion plate. The float and winch with the anti-erosion plate suspended from the winch cable is then lifted by a shore based crane and deposited in the water treatment basin adjacent the boundary of the basin. The float with the anti-erosion plate buoyantly supported thereby, is moved to the desired location in the basin and the winch then operated to lower the anti-erosion plate onto the bottom of the basin. The float is thereafter moved back to the boundary of the basin. The winch is removed and the motor pump unit then assembled on the float, after which the floatable pump apparatus is floated back to a position over the anti-erosion plate and anchorerd in that location.
