Definitions

  • the invention relates to a well pipe according to the preamble of Claim 1.
  • Such well pipes are using coupling members can be assembled into a tensile pipe string which is used for
  • the piping of a well serves as individual well pipes
  • Filter tubes can be formed at least at intervals are arranged within the pipe string.
  • DE-OS 17 86 014 discloses a well filter tube, which has a support body designed as a skeleton or cage, which is provided with a surrounding jacket, which is a gravel pack is trained. It is assumed that the ends the cage at both ends of the filter tube from the gravel pack protrude to connect two successive pipes together to be able to.
  • This well-known well filter tube is proportional heavy because the support body designed as a cage or the like obviously made of metal. It also shows the Disadvantage that it is due to the presence of this scaffold is not easily dredged. This property is of particular importance if the well filter tube for drainage purposes in opencast mining, especially in lignite opencast mining, is used in areas that will be covered later Use of a bucket wheel excavator excavated become.
  • a well filter tube is known from DE-OS 17 84 288, which since it's just made from a granular bonded by resin Pack consists, without further dredging. Are there the two connecting sections located at the ends of the tube provided with a larger proportion of binder, so that they have greater strength.
  • the Connecting sections attached circumferential grooves that interact with one of the connecting sections of two neighboring Pipes joint sleeve each form a channel in a connecting element in the form of a coated wire rope section can be introduced.
  • the invention is based on the object to design well pipes of the type described in the introduction, that it has sufficient strength with a light weight, which also allows hanging well development without that asbestos cement would have to be used to manufacture it.
  • the production of the well pipe should also take place when it is is designed as a filter tube, at least not more difficult and be more complex than the known filter tubes.
  • the well filter tube 10 has a proportionate at each end short connecting section 12 made of polymer concrete and a section 14 located in between, as a gravel adhesive filter is formed and made of filter gravel and polyester or Vinyl ester resin is made. These resins can also act as binders can be used for the polymer concrete.
  • the well filter tube 10 is made of resin-bonded glass fiber rods 16 provided between its end faces 18th extend and run close to the inner boundary wall 20. This is essentially due to the fact that in the embodiment the well filter tube 10 in the area 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 can for example be provided with a diameter of 3-9 mm. Such glass fiber rods can have a tensile strength of more than 100 n / mm 2 .
  • the glass fiber rod can be designed on the outside so that the formation of a smooth surface is avoided. This can be achieved, for example, in that a wire or possibly also a glass fiber roving is spirally wound onto the glass fiber rod in order to achieve a positive connection between the glass fiber rod and polymer concrete or gravel filter.
  • the number of glass fiber rods depends on the particular circumstances, including the diameter of the well filter tube. In the majority of cases, about 20 to 25 such glass fiber rods will be arranged at regular intervals around the circumference.
  • the gravel filter 14 Since the gravel filter 14 must have a minimum permeability, which requires a pore volume of, for example, 36% is his Compressive strength noticeably lower than that of polymer concrete which the connecting sections 12 exist. However, this is of minor importance since it is essentially on it arrives that the pipe with vertical, i.e. hanging installation, Is able to absorb and transmit tensile forces.
  • the Connection to the neighboring pipe can be made via a sleeve take place, the respective connection section and that of adjacent connecting section of the adjoining pipe encloses, 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 in the outside of the respective Connecting section 12 engages groove 22.
  • the one in the effective multi-tube axial pipe run These connecting elements cause tensile forces from pipe to Pipe transferred. The transmission takes place within the individual pipes the axial tensile forces essentially through the synthetic resin-bound Fiberglass rods.
  • the pipes are manufactured in a form that the outer and inner boundary of the tube defined.
  • the glass fiber rods are initially a ring-shaped form arranged and stressed on train, then successively first the material for the lower connecting section 12, then the material for section 14 made of filter gravel and then the material for the upper connection section be filled in.
  • the filled material will, before it starts to harden, compacted by a vibrator, taking it as far as the gravel filter concerns, the desired pore volume is to be observed.
