Field of the Invention This invention relates to a method and means for reducing stress in a pivot irrigation pipeline and more particularly to a method and means for reducing stress in a pivot irrigation pipeline by allowing the pipeline to separate while maintaining the same in proper alignment to facilitate reconnection. 2. Description of the Related Art Center pivot irrigation systems comprise a center pivot structure having an elongated water pipeline extending outwardly therefrom which is supported upon a plurality of spaced-apart drive towers.
A method and means is described for reducing stress in a pivot irrigation system by allowing the pipeline to separate from the center pivot structure during periods of cooler temperatures. It is therefore a principal object of the invention to provide a method and means for reducing stress in a pivot irrigation pipeline when cooler temperatures are experienced. These and other objects will be apparent to those skilled in the art. Valley Center Pivot choices.
