Problems solved by technology

In addition, due to stretching, the plastic mesh is deformed in multiples of its length, so that a flow path cannot be formed along the plastic mesh
The plastic mesh that can be produced according to the method in DE2400941C2 cannot be used as a plastic drainage board

Embodiment Construction

[0064] Figure 1 to Figure 3 An exemplary embodiment of a plastic drainage board is shown. The plastic drainage board 1 has a plate-shaped body 2 . The plate-like body 2 extends in a longitudinal direction 3 and a transverse direction 4 extending perpendicularly thereto. figure 1 Only a part of the plastic drainage board 1 is shown. The plastic drainage board 1 extends in the longitudinal direction 3 over figure 1 the part shown in. figure 2 A longitudinal section through the plastic drainage board 1 is shown along the cutting edge II-II in the longitudinal direction 3 . image 3 A cross section through the plastic drainage board 1 along the cutting edge III-III in the transverse direction 4 is shown.

[0065] The plastic drainage board 1 has a length in the longitudinal direction 3 and a width B in the transverse direction 4 . The longitudinal direction 3 and the transverse direction 4 span the plane of the plate. The main body 2 of the plastic drainage board 1 has a ...

Abstract

The invention relates to a method for producing a plastic drainage sheet and to a plastic drainage sheet. For the production, a sheet-shaped main body (2) having a first surface (5) and a second surface (6) spaced apart from the first surface by a main sheet thickness is provided. Grooves (7) are formed in the first surface (5), and counter grooves (8) are formed in the second surface (6). The counter grooves (8) and the grooves (7) cross at crossing points (9). Passage openings (10) between the grooves (7) and the counter grooves (8) are formed at the crossing points (9).

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority from German patent application DE 102018211667.9, the content of which is hereby incorporated by reference. technical field [0003] The invention relates to a method for the manufacture of plastic drainage boards. In addition, the present invention relates to a plastic drainage board. Background technique [0004] Plastic drainage panels can also be called composite geotechnical drainage panels (GDS). They are used in mining, landfill construction, tunnel construction, road construction or other geotechnical applications. In this respect, it is desirable to ensure a sufficiently high drainage capacity by means of plastic drainage panels. Geonets (GNT) are often used as plastic drainage panels, especially where pressure loads are high. Geonets are produced in installations specially designed for this purpose. US2009 / 0041544A1 discloses a geonet and its manufacturing method. ...
