WELL WITH HORIZONTAL FILTER TUBES AND PROCEDURE FOR BUILDING OR REPAIRING WELL WITH HORIZONTAL FILTER TUBES

The invention relates to a radial collector well comprising a well shaft (4) sunk in a direction perpendicular to the soil surface such that it reaches the confining layer (2), and collectors (5) or at least one collector (5) jacked into the filter layer (3), where the collectors (5) are disposed in at least one plane, and each collector (5) consists of multiple collector segments connected to one another. The essential feature of the invention is that the collector segments are made from bridge perforated sheet metal, and the collector segments are connected to each other with sleeve joints. According to the method, collectors (5) or at least one collector (5) is jacked from the well shaft (4) of the existing well into the filter layer (3) in a direction perpendicular to the well shaft (4), where the collectors (5) are disposed in at least one plane, and where the collectors (5) are produced by sequentially jacking and interconnecting collector segments. The essential feature of the method is that prior to or simultaneously with collector (5) jacking the filter layer (3) is loosened and dislodged utilizing high-pressure water jet in the vicinity of the collectors (5), the resulting slurry is brought into the well shaft (4), the collector segments (7) are sequentially jacked into the loosened filter layer (3), and the collector segments (7) are connected to each other with sleeve joints.
