Abstract

Tverrelement-enhet (10) for bruk i et tverrdrenerings-distribusjonssystem er tilvirket av plast, men er like godt egnet som mye tyngre og mer kostbare tidligere kjente metall- enheter til å bære et sjikt med filtermedia som må periodisk tilbakespyles med væske og gass. Komplementære elementer, innbefattende et stivt, ekstrudert gulvplateelement (22) med langsgående sidekant-kanaler (40) og et overliggende silelement (20) som har flenspariiei (38) tilpasset til å bli fastholdt av underskårende forsenkninger i sidekant- kanalene, blir montert til hverandre for å danne hule tverrgående distribusjonsenheter. I en utførelse er silelementet teleskopisk montert til gulvplateelementei for å fa silflenspartiene til å låse seg sammen med forsenkningene i sidekant-kanalene. Den resulterende enhet er forseglet mol lekkasje der hvor elementene er låst sammen ved hjelp av et par fleksible, integrerte tetningsstrimler av plast som er sam-ekstrudert med det stive gulvplateelement.
