Device and Method for Keeping Channels Clear of Silt

摘要

A method of forming a maintenance free channel is disclosed. The method consists of positioning a plurality of curtain devices along a desired path in a waterway. The curtain devices each consists of an elongated float and an elongated flexible curtain depending from a first side of the elongated float. The elongated curtain has a bottom end with a weight extending along the entire length of the elongated float. The elongated float is configured to be sufficiently buoyant to support the curtain in an upward direction. The length of the elongated float is selected to equal a desired length of the channel. The height of the elongated flexible curtain is selected to be approximately equal to the depth of the waterway such that the elongated weight remains on the bottom while the elongated cylindrical float remains on the surface.

主权项

1. A device for forming a channel in a water way to prevent the buildup of silt on a bottom of the waterway and for marking the channel on the surface of the waterway, the device comprising:
a. An elongated cylindrical float having a length and a first side; b. An elongated flexible curtain depending from the first side of the elongated cylindrical float and extending along the entire length thereof, the elongated curtain having a bottom end opposite where the elongated curtain depends from the elongated cylindrical float; c. An elongated weight formed on the bottom end of the elongated flexible curtain, the elongated weight extending along the entire length of the elongated cylindrical float, the elongated cylindrical float being sufficiently buoyant and the elongated flexible curtain having a height being selected to keep the elongated weight at the bottom of the waterway while the elongated cylindrical float is at the surface; d. The length of the elongated float selected to form the channel.
