Definitions

  • DE 511 302 A teaches a double slot tube filter consisting of an outer copper tube and an inner copper tube, the space between the outer and inner tubes being filled with equal diameter glass balls.
  • DE 1 301 300 teaches a filter tube with a base body made of asbestos cement or plastic, wherein on the wall of the base body outside a shell-shaped filter layer formed by a gravel pack is arranged.
  • DE 198 53 211 C2 shows a well pipe with extending in its longitudinal direction within its wall and spaced over the circumference of the tube spaced bars, wherein the wall is made of polymer-bound gravel-like grains.
  • the well pipe has at each of its ends a connecting portion consisting of polymer concrete and at its connecting portions a filter-formed portion is arranged, which also consists of polymer-bound gravel-like grains.
  • DE 453 876 teaches a well filter of individual superimposed, held together by long bolts filter baskets that have a gravel filling.
  • sand and gravel according to DIN 4924 are to be installed in the area of the aquifer covered with the filter tube.
  • DIN 4924 applies to sands and gravels for the production of gravel beds in well construction.
  • the invention specified in the claim is based on the use of glass beads instead of the gravel and sands described in DIN 4924.
  • a further embodiment of the invention is that the glass beads are not poured into the annulus behind the filter tube, but with suitable materials such. Bulk baskets, industrial materials or composites are attached to the filter tube before the tube is installed.
  • FIG. 1 An embodiment of the invention is in as FIG. 1 attached drawing.
  • FIG. 2 and FIG. 3 represent the enlargement of the pore space and, consequently, the improvement of the permeability when using glass beads.
