Abstract

SE PRESENTA UN SISTEMA DE DRENAJE SUBTERRANEO LATERAL, QUE ESTA ESPECIALMENTE ADAPTADO PARA SU USO EN LECHOS FILTRADORES POR GRAVEDAD, QUE INCLUYE, EN SU CONFORMACION MAS ADECUADA, UNAS PARTES LATERALES EN FORMA DE CONCHA (26, 126) QUE TIENEN UNA SUPERFICIE TAMIZADORA, RANURADA, CON ALAMBRE ENROLLADO (28). LA SUPERFICIE TAMIZADORA SOPORTA Y RETIENE LAS PARTICULAS DEL MEDIO FILTRADOR (118) SIN LA NECESIDAD DE NINGUNA CAPA DE GRAVA SUBYACENTE Y ESTA AUTOSOPORTADA POR UNOS MIEMBROS DE VARILLA EN FORMA DE CANAL (34) QUE ESTAN SOLDADOS A LOS ALAMBRES (30). LAS BANDAS (36) DE LOS MIEMBROS DE VARILLA EN FORMA DE CANAL REALIZAN LA FUNCION DE DISTRIBUIR SIMULTANEAMENTE AIRE Y AGUA DURANTE LA OPERACION DE LAVADO, E INCLUYEN UN AREA TOTAL MENOR DE ABERTURAS (38) EN LOS CANALES SUPERIORES Y UN AREA TOTAL MAYOR DE ABERTURAS (40) EN LOS CANALES INFERIORES PARA PROVOCAR QUE SE FORMA UN PLENUM (56) DENTRO DE LOS LATERALES LO QUE ASEGURA QUE LA DISTRIBUCION DEL AIRE Y EL AGUA SERA UNIFORME A TODO LO LARGO DEL LATERAL, INCLUSO SI EL LATERAL NO ESTA PERFECTAMENTE NIVELADO. LA DISTRIBUCION DEL AIRE Y EL AGUA A TRAVES DE TODOS LOS LATERALES SE HACE INCLUSO MAS UNIFORME MONTANDO LOS LATERALES SOBRE UN TUBO COLECTOR (124) Y SUMINISTRANDO TUBOS DE FLUJO PERFORADOS (122) QUE SE EXTIENDEN DESDE CADA LATERAL AL INTERIOR DE LA TUBO COLECTOR PARA PRODUCIR UN PLENUM DE AIRE ADICIONAL (135) EN LOS MISMOS.
