Irrigation Techniques - Solid set sprinkler systems - Part 1: Selection, design, planning and installation
This document provides guidelines to choose material, to design, to prepare plans, and to install a solid set irrigation system to apply water to the irrigated area with the greatest possible efficiency.
This document covers sprinkler irrigation systems installed at the beginning of the irrigation season and removed at the end without moving any component, sprinkler or pipe, during the entire irrigation season.
It covers only solid set system components located on the field and upstream from a water supply point defined by a pressure and a flow.
This document does not cover permanent systems with buried pipes nor hand-movable portable systems.
Bewässerungsverfahren - Ortsfest installerte Beregnungssysteme - Teil 1: Auswahl, Auslegung, Planung und Installation
Dieses Dokument gibt eine Anleitung für die Materialauswahl, die Auslegung, die Erstellung von Plänen und
die Installation von ortsfest zu installierenden Beregnungssysteme, die dazu vorgesehen sind, das Wasser mit
größtmöglicher Wirtschaftlichkeit auf die zu bewässernde Fläche aufzubringen.
Dieses Dokument behandelt als Beregnungssysteme ausgeführte Bewässerungsanlagen, die zu Beginn der
Bewässerungssaison installiert und an deren Ende abgebaut werden, ohne dass während der gesamten
Bewässerungssaison irgendeines ihrer Bauteile ? weder Regner noch Rohrleitung ? bewegt würde.
Sie behandelt nur ortsfest installierte Bauteile der Anlage, die sich auf dem Feld und oberhalb eines durch
Druck und Gefälle definierten Wasserversorgungspunktes befinden.
Dieses Dokument behandelt weder dauerhaft installierte Anlagen mit unterirdisch verlegten Rohrleitungen
noch per Hand umzusetzende, tragbare Anlagen.
