Definitions

  • the present invention relates to an irrigation installation, comprising a series of water container containers, distributed over the area to be irrigated, at least partially buried in the ground, and a network of pipes connecting said containers with each other and with a water supply source.
  • the object of the invention is to provide a suction irrigation system through the porous wall containers, which are arranged buried in the ground, next to the plants to be irrigated, at the desired depth, and which supply the soil with water in quantity dependent on variables such as crop type, soil characteristics, water availability and any other parameter of agronomic, technical or economic interest.
  • irrigation through exudation belts or hoses requires pressure, at least about 5 meters of water column, at least, being porous materials that are not rigid.
  • Exudation tapes are superficial or slightly buried pipes that with water pressure swell and exude water, that is to say drip and moisturize the soil.
  • the present invention aims at an irrigation installation, with suction irrigation emitting vessels, in which the soil sucks from said emitters more or less water depending on the moisture content of the soil, without having to maintain pressure on the irrigation emitters or the pipes that feed them.
  • the irrigation emitters consist of water-containing containers with rigid and porous walls, permeable to water, at least in certain areas or areas of said walls.
  • These containers consist of a sintered plastic material, preferably of a plastic material selected from the group consisting of polyethylene (PE), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), ethylene acetate vinyl (EVA), polypropylene (PP), polybutylene (PB-1), polystyrene (PS), polyamides (PA), polyethersulfone (PES), polytetrafluoroethylene (PTFE), thermoplastic polyurethane (TPU), as well as any combination thereof.

  • the container that becomes part of the installation of the invention allows watering the soil where it is installed thanks to the permeability of its walls.
  • the container carries out a localized, underground and self-regulated irrigation due to the humidity or dryness in the soil itself, without the need for pressure on the branch during irrigation, which results in a significant saving of water and energy.
  • the flow rate emitted by a container full of water of 1 L capacity is 0.10 Lh 1 , a value that is used to estimate its emptying time and filling interval: approximately one day.
