Abstract
An overflow system for a hopper dredger includes an overflow tube; and a plurality of canals adjacent and substantially parallel to the overflow tube. The plurality of canals have inlets at different heights for taking in head water from the hopper. The plurality of canals fluidly connect to the overflow tube at a point downstream from the inlets.
Claims20
An overflow system for a hopper dredger, the overflow system comprising:
- an overflow tube;
- and
- a plurality of canals adjacent and substantially parallel to the overflow tube, the plurality of canals having inlets at different heights for taking in head water from the hopper;
- wherein the plurality of canals fluidly connect to the overflow tube at a point downstream from all of the inlets.
An overflow system add-on for an overflow system comprising an overflow tube with a pipe in a hopper, the add-on comprising:
- a plurality of canals, each canal with an inlet at a different height, connectable adjacent to or inside of the overflow tube such that the inlets of the plurality of canals will sit at a lower level than an inlet of the overflow tube and that the plurality of canals fluidly connect to the overflow tube downstream from all of the inlets.
A method of forming an overflow system, the method comprising:
- connecting a plurality of canals adjacent to an overflow tube in a hopper;
- and
- fluidly connecting the plurality of canals to the overflow tube downstream from inlets such that liquid entering inlets of the plurality of canals will be transported to the overflow tube downstream from all of the inlets, wherein the plurality of canals are sized and/or positioned such that the respective inlet to each canal is at a different height.
