16 TITLE LINEAR BARRIER FOR SEPTIC TANKS INVENTOR Alan G. HINES APPLICANT 638755 ONTARIO INC. Concrete septic tanks have inflow and outflow orifices and near the outflow orifice have screening means or baffles which are stapled or bolted to the concrete inner wall so as to force the outflowing liquids to pass a predetermined flow path with the hope to avoid solids passing out of the tank and into a draining tile bed. A novel baffle structure and means for attaching the baffles is disclosed using a linear race with foreward and rearward recesses and flexible marginal flap that seals the race onto a core surface of a mold use to fabricate the tank. After the concrete is poured into the mold and partially cured the core is then removed, and the track remains embedded in the concrete and acts as a holding, sealing and anchoring means for a baffle, preferably made of a non-corrosive material such as a plastic. The baffle is slipped into the race of the track and seepage across the baffle interface with the tank walls is avoided and the predetermined flow path for the outflowing fluids is ensured. In order to inhibit the outflow of Hydrogen and Hydrogen Dioxide gases, an inclined plate can be placed beneath the outflow channel to deflect entrained gases from flowing up into the outflow channel and outflow orifice and into the draining tile bed. |
