<p>The invention concerns an economical, efficient, practical and easy-to-use modular drainage unit capable of efficiently collecting and evacuating drainage water and designed to provide a global solution for producing a very simple drainage process. Said modular drainage unit (1) is characterised in that it comprises an elongated body (2), traversed by a longitudinal collecting conduit (3), and comprising flow passages (5) opening on the peripheral walls of said body (2) and emerging into said collector conduit (3), said flow passages (5) being arranged to enable drainage water to circulate by gravity towards said collecting conduit (3), and it comprises connecting means (6) designed to assemble two successive drainage units (1) and further comprises an outer water permeable casing (7) to trap soil. The invention is useful for draining grounds in general and around buildings.</p> |
