Title (EN) RADON TREATMENT SYSTEM AND METHOD
(FR) PROCEDE ET SYSTEME DE TRAITEMENT DE RADON
Abstract:
(EN) The system for removing the soil gas from the ground surrounding the building structure (12), includes a drain tile system (10), a clean-out pipe (64), an air duct system (46), and a fan (60). The air duct system is securable to a clean-out pipe, and the fan is installed inside the air duct system. The air duct system is disconnected from the clean-out pipe during the cleaning of the drain tile system. A pressurized fluid projecting through the tip of a rocket nozzle (32), removes any obstructions in the drain tile, and the pressurized fluid projecting rearward from the nozzle, propels the rocket nozzle through the drain tile system. The air duct system is then connected to the clean-out pipe. The venting of air away from the drain tile system creates a negative pressure, which draws the soil gas into the porous drain tile whereby the soil gas is effectively prevented from entering the building structure.
(FR) Un système d'élimination du radon gazeux contenu dans le sol autour de la structure (12) d'un bâtiment comprend un système (10) de tuyaux de drainage, un tuyau de vidage (64), un système (46) de conduits d'air et un ventilateur (60). Le système de conduits d'air peut être assujetti à un tuyau de vidage et le ventilateur est installé à l'intérieur du système de conduits d'air. Le système de conduits d'air est déconnecté du tuyau de vidage pendant le nettoyage du système de tuyaux de drainage. Un jet de fluide pressurisé projeté par la pointe d'une buse-fusée (32) enlève toutes les obstructions des tuyaux de drainage et le jet de fluide pressurisé projeté en arrière par la buse fait avancer la buse-fusée à travers le système de tuyaux de drainage. Le système de conduits d'air est ensuite connecté au tuyau de vidage. L'évacuation de l'air contenu dans le système de tuyaux de drainage crée une pression négative qui attire le gaz contenu dans le sol dans les tuyaux poreux de drainage, ce qui empêche de manière efficace le gaz contenu dans le sol de pénétrer dans la structure du bâtiment.
