摘要
A ground water flow device 1 has a support element 3 and a filter sheet 5. The filter sheet 5 has a first side 7 and a second side 9. Tubes 13 are provided with flow apertures 11 which are large enough to allow the passage of water and soil particles. The tubes 13 each have an inner space 17. The tubes 13 each hold one of the filter sheets 5 in their inner space 17. A first part of the flow apertures 11 is facing the first side 7 of the filter sheets 5 and a second part of the flow apertures 11 is facing the second side 9 of the filter sheets 5, defining in each tube 13 a flow path 19 for ground water from the first part of the flow apertures 11 through the filter sheet 5 to the second part of the flow apertures 11.
