Definitions

  • the invention relates to a well pipe according to the preamble of Claim 1.
  • Such well pipes are using coupling members to a tensile pipe string composable to the Casing a well serves, with individual well pipes as Filter tubes may be formed, at least at intervals are arranged within the tubing.
  • DE-PS 13 01 300 discloses such a Filter tube with a support tube made of asbestos cement or plastic, its wall provided with holes on the outside by a wearing a gravel pack formed jacket-shaped filter layer. These holes are needed for that to go through the Filter layer flowing water into the interior of the support tube can occur.
  • These known well filter tubes have the disadvantage that attaching the holes in the walls considerable cost caused.
  • the free filter surface in these known pipes through the wall portions of the support tube, the between the holes of the same exist, a considerable Restriction experiences.
  • DE-OS 17 86 014 discloses a well filter tube, which having a skeleton or cage formed supporting body, which is provided with a circumferential jacket, which is used as gravel packing is trained. It is assumed that the ends of the cage at both ends of the filter tube from the gravel pack protrude to connect two consecutive pipes together to be able to.
  • This known well filter tube is relatively difficult because of the cage or the like. trained supporting body obviously made of metal. In addition, it has the Disadvantage of it being due to the presence of this scaffold can not be easily dredged. This property then comes a special meaning when the well filter tube for drainage purposes in surface mining, in particular lignite mining, used in areas later under Use for example of a bucket wheel excavator dredged become.
  • the invention is based on the object To design a well pipe of the type described in the introduction, that it has sufficient strength with light weight, which also allows a hanging well extension, without that asbestos cement should be used for its production. This is the production of the well pipe even if it is designed as a filter tube, at least not difficult and be more expensive than the known filter tubes.
  • This task is characterized by the combination of the characteristics of the Claim 1 listed features solved.
  • the well filter tube 10 has a relative at each end short connecting portion 12 made of polymer concrete and a intervening section 14 on, as a gravel adhesive filter is formed and made of filter kieses and polyester or Vinylesterharz exists. These resins can also act as binders be used for the polymer concrete.
  • the well filter tube 10 is made with resin-bonded glass fiber rods 16 provided between its end faces 18 extend and extend near the inner boundary wall 20. This is essentially due to the fact that in the embodiment the well filter tube 10 in the region of the connecting sections 12 has a much smaller wall thickness than in the area of the gravel filter 14.
  • the glass fiber rods 16 may for example be provided with a diameter of 3 - 9 mm. Such glass fiber rods may have a tensile strength of more than 100 n / mm 2 .
  • the glass fiber rod can be externally formed so that the emergence of a smooth surface is avoided. This can be achieved, for example, by spirally winding a wire or optionally also a glass fiber roving on the glass fiber rod in order to achieve a positive connection between glass fiber rod and polymer concrete or gravel filter.
  • the number of glass fiber rods depends on the particular conditions, including the diameter of the well filter tube from. In the majority of cases, about 20 to 25 such glass fiber rods will be distributed around the circumference at regular intervals.
  • the gravel filter 14 Since the gravel filter 14 must have a minimum permeability, which requires a pore volume of, for example, 36% is its Compressive strength significantly lower than that of polymer concrete, from which consist of the connecting portions 12. This is however of subordinate importance, as it essentially assures arrives that the pipe in vertical, so hanging installation, Is capable of absorbing and transmitting tractive forces.
  • the Connection to the adjacent pipe can be via a sleeve take place, the respective connecting section and the of the adjacent connecting portion of the adjoining tube encloses, wherein the positive connection between the not shown sleeve and the respective connection section 12 z. B. in a known manner by a wire rope or a polyamide rod takes place, the or in the outside of the respective Connecting portion 12 mounted groove 22 engages.
  • the in the from several pipes existing pipe string effective axial Tensile forces are due to these fasteners of pipe too Transfer tube. Within the individual tubes, the transfer takes place the axial tensile forces essentially by the resin-bonded Fiberglass rod
  • the production of the tubes takes place in a form that the outer and inner boundary of the tube defined.
  • a ring performing form are initially the glass fiber rods arranged and claimed on train, whereupon successively First, the material for the lower connection section 12, then the material for section 14 of filter gravel and then the material for the upper connecting portion be filled.
