ABSTRACT:
An anti-rotation pipe clamp type of apparatus is described for securing a section of gated irrigation pipe thereto. The section of gated irrigation pipe is placed on top of the ground surface. One or more anti-rotation pipe clamps are used, as necessary, to prevent the various sections of gated irrigation pipe from rotating axially as they are periodically heated and cooled. The anti-rotation pipe clamp includes a base that is placed on top of the ground surface and maintains the anti-rotation pipe clamp in a predetermined attitude with respect to the ground surface that is generally parallel thereto. A clamping mechanism is attached to the base that includes a flexible strap which is attached to the base at one end and which surrounds a portion of the gated irrigation pipe. A winch is used to tighten the flexible strap around any of a variety of sections of gated irrigation pipe each having a particular outside diameter and to secure the particular section of gated irrigation pipe to an arcuate surface that is attached to the anti-rotation pipe clamp. When the section of gated irrigation pipe is secured to the anti-rotation pipe clamp, the base prevents the anti-rotation pipe clamp from axially rotating with respect to the ground surface which, in turn, prevents the section of gated irrigation pipe from axially rotating with respect to the ground surface.
