GEOTEXTILE

Abstract

A geotextile tube connecting unit comprises a flange ring (20), a support ring (30), and connection means (22) for connection of the flange ring (20) to the support ring (30) while including the geotextile base fabric (10) in-between. The geotextile base fabric (10) is subdivided into at least two segments (14) in the area of the filling opening (11), each segment (14) being bent outwards over at least one welt element (12). The welt element (12) is interlockingly held in place on the flange ring (20) and/or on the support ring (30) on at least one contact edge.

Description

[0014] The screw connection of the flange ring to the support ring can be effected in various ways, as will be explained below with reference to the exemplary embodiments illustrated in the following drawings. The figures show in detail:

[0015] FIG. 1 a mounted geotextile tube connecting unit in a perspective view from the outside

[0016] FIG. 2 a geotextile tube connecting unit according to a first mounting step in a top view

[0017] FIG. 3 a geotextile tube connecting unit according to a second mounting step in a top view

[0018] FIGS. 4a-4c geotextile tube connecting units with different embodiments of a flange ring, each in a sectional view.

[0019] FIG. 1 shows a geotextile tube connecting unit 100 on a geotextile container, of which a section of a geotextile basic fabric 10 can be recognized. The geotextile tube connecting unit 100 comprises a flange ring 20 attached externally to the base fabric 10, which is covered here by a tube guide neck 40. The tube guide neck 40 is attached to the flange ring 20 by means of a clamp 50 and is also made of a geotextile. Its purpose is to facilitate the insertion of a flushing tube into the filling opening and to fasten the flushing tube thereon. To this end, the flushing tube can, for example, be secured using a tensioning belt that is placed around the tube guiding neck 40 or is interwoven therein.

[0020] FIG. 2 shows a partially mounted geotextile tube connecting unit 100. The filling opening 11 is already cut free forming a plurality of segments 14. These are each turned over to the outside onto the geotextile base fabric 10 and secured thereon by a seam 13, wherein each is guided around a keder element 12 with a wrap angle of 180 and more.

[0021] In the embodiment shown here, an opening 15 is introduced in each segment 14 and in the underlying base fabric 10, so that, for example a screw can pass through as a connecting means. The filling opening 11 is thus encompassed by the keder element 12, which is enveloped in the fabric 10.

[0022] In the illustration in FIG. 3, the flange ring 20 is placed onto the outer surface of the fabric 10 and now covers the keder element 12. Inside, the filling opening 11 is exposed. Screws establish a connection to a support ring, which is positioned on the opposite surface of the base fabric 10.

[0023] FIG. 4a shows a section through a first embodiment of a geotextile tube connecting unit 100. The transition of the base fabric section 10 into a segment 14 that surrounds the keder element 12 and is then clamped together with the base fabric 10 between the flange ring 20 and the support ring 30 can be recognized; the screw connection 22 is located on a partial circle outside the keder element 12. The keder element 12 is form-fittingly secured in a groove 21 (see FIG. 4a) of the flange ring 20 that is open toward the inner circumference. On the outer circumferential surface, a further groove 23 is introduced in order to secure the tube guide neck 40 therein by means of a tube clamp 50 or the like.

[0024] FIG. 4b shows a section through a geotextile tube connecting unit 100 according to a second embodiment. Here, a flange ring 20 is provided that has a groove 21 on its lower contact surface with the base fabric 10. An outer limiting edge in the groove 21 serves the abutment and the form-fitting securing of the keder element 12. The part of the flange ring 20 that extends beyond the groove 21 completely covers the keder element 12, so that the latter, together with the fabric sections 10, 14 that surround it, is better protected from mechanical abrasion by a tube neck inserted into the filling opening 11. The connection of the rings 20, 30 and the associated clamping of the segments 14 to the base fabric 10 is effected by means of a screw connection 22, which is arranged on a partial circle outside the keder element 12.

[0025] A third embodiment of a geotextile tube connecting unit 100 is shown in FIG. 4c. Again, a groove 21 for accommodating the keder element 12 is introduced into the flange ring 20 on the bottom side. However, this one is moved further outwards, whereas the partial circle for the screw connection 22 now lies within the annular keder element 12. This does reduce the clear opening of the filling opening 11 somewhat. However, the advantage of the screw connection 22 on the inside is that penetrations for passing through screws can be completely omitted in the base fabric 10 and in the segments 14 and material weakening is avoided.

[0026] FIG. 4d shows a section through a fourth embodiment of a geotextile tube connecting unit 100. The transition of the base fabric section 10 into a segment 14 that surrounds the keder element 12 and is then clamped together with the base fabric 10 between the flange ring 20 and the support ring 30 can be recognized. In the embodiment shown here, both the flange ring 20 and the support ring 30 are designed with a flat surface facing the fabric 10. The screw connection 22 is located on a partial circle outside the keder element 12. The keder element 12 is located within the opening of the flange ring 20 and is form-fittingly secured at the inner circumferential surface 24 of the flange ring 20. On the outer circumferential surface, a further groove 23 is introduced in order to secure the tube guide neck 40 therein by means of a tube clamp 50 or the like.
