ABSTRACT:
An irrigation pipe comprising a first elongated pipe portion, an intermediate pipe portion which extends at an angle from one end of the first pipe portion, and a second pipe portion extending from the intermediate pipe portion parallel to the first pipe portion. The ends of the first and second pipe portions are adapted to be connected to other irrigation pipes. A hollow tubular member is secured to the intermediate pipe portion and extends outwardly therefrom and is aligned with the central longitudinal axis of the first pipe portion. The interior of the tubular member is in communication with the interior of the intermediate pipe portion. A gravel screen is positioned in the first pipe portion and is substantially conical in shape with one end thereof being substantially equal in diameter to the interior of the first pipe portion. A pipe stub is secured to the other end of the gravel screen and extends therefrom through the tubular member in a sealed relationship with respect thereto. A valve or the like is provided on the outer end of the pipe stub to permit the gravel collected by the interior of the gravel screen to be flushed therefrom outwardly through the pipe stub.
