Definitions

  • the invention relates to a plastics corrugated pipe provided with apertures in its valleys, said pipe being surrounded by a water permeable covering.
  • Plastics corrugated pipes having apertures in their valleys are used on a large scale for draining purposes.
  • plastics corrugated draining pipes of this type In order to prevent a blockage of the apertures by means of small soil particles, which involves a considerable decrease of the supply of water, to plastics corrugated draining pipes of this type, it is known in the art to surround the plastics corrugated pipe with glass fibre mats, or with strips of fibrous material, like for instance cocos fibres.
  • the plastics corrugated pipe may even be surrounded with a rockwool fibre wrapping in accordance with an unpublished recent proposal.
  • An additional disadvantage of a surrounded plastics corrugated pipe is that the properties of the surrounding covering will not remain constant in the time, as water permeable surrounding coverings consisting of such fibres are sensitive to biological attack and/or deposits of iron oxide from soil water.
  • the water permeable surrounding covering is in most cases in contact with the respective apertures, thus causing these apertures to be partially closed.
  • the present invention aims to provide a plastics corrugated pipe of the abovementioned type, alleviating the aforementioned disadvantages, whereby particularly the surrounding covering is only little in weight, is not vulnerable during transport and can be applied by means of known machines for installing plastics corrugated pipes, whilst, furthermore, said pipe with surrounding covering can be supplied from a supply reel.
  • plastics corrugated pipe is surrounded by a gas cushion foil layer covering, comprising one or more water permeable zones being on the one hand connected with the respective apertures and on the other hand with the surroundings of the covering.
  • said surrounding covering in accordance with the invention filtrate selectively, in other words, their constructions prevents a penetration of soil particles of a certain size and permits a passage of very fine soil particles which remain suspended.
  • the surrounding covering consists of plastics cushion foil layers of small width, wrapped cross-wise around the pipe.
  • a covering of this type will permit the respective water stream to sidewise enter below the foil whereupon said liquid will be discharged through the channel system between the cushions towards the apertures in the plastics corrugated pipe.
  • Said strips may advantageously be heatsealed to a mat, thus providing a covering which is easily to be installed.
  • a very benificial embodiment of the present invention comprises the presence of filter material in between the gas cushions, e.g. in the form of polystyrene grains.
  • the used gas cushion foil layer can be subjected to greater or smaller deformations, thus permitting the cross-section of the flow channels formed by the spaces 16 between the air cushions 6 to be varied, so that a so-called coarse or fine filter can be obtained from one and the same gas cushion foil layer.
  • the gas cushions 6 and 6a which preferably present a staggered pattern with respect to each other, may either be interconnected by means of an adhering layer 12, or by a sealed connection 12.
  • Fig. 4 still shows another embodiment in which a water permeable tubular covering 13 is used, which has also been heat- shrunk around the plastics corrugated pipe-I.
  • certain cushions 6 comprise a perforation 17 in their tops 14 and a perforation 11 in their bottom part.
  • the liquid to be discharged flows into cushions 6 via perforations 17 and subsequently through perforations 11 into the wave valleys 2 from which said liquid arrives in the plastics corrugated pipe 1 via apertures 4.
