NATURAL WATER FILTERING AND INTAKE DEVICE BY USING PERFORATED DRAIN PIPE

摘要

PURPOSE: A natural water filtering and intake device by using a perforated drain pipe is provided to secure abundant water by purifying water flowing right under the earth's surface and to save underground water resources getting exhausted. CONSTITUTION: A natural water filtering and intake device by using a perforated drain pipe(200) is composed of a cut-off wall(100) mounted under the ground at constant depth to cut off the stream flowing right under the earth's surface; a filtering device filled up in the cut-off wall to filter the cut-off water; the perforated drain pipe installed in the filtering device to desalinate the filtered water; and an intake pipe(300) connected to the perforated drain pipe and not exposed out of the earth's surface. The cut-off wall comprises a first cut-off wall for cutting off the stream from the front side and second and third cut-off walls inclined inward at the constant angle and extended at both sides of the first cut-off wall to guide the stream toward the first cut-off wall.
