Abstract[English]
A plug for sealing injection ports in concrete elements comprises a fully threaded bolt, a threaded anchor adapted to engage an internal thread of the injection port and to retain the plug securely under high pressure, and an expanding rubber seal positioned between two conical washers. Tightening a nut on the bolt compresses the expanding rubber seal between the conical washers, causing the seal to expand radially against the wall of the injection port to prevent water leakage and form a watertight closure. The design allows quick installation, predictable positioning, reliable sealing even under high water pressure, and later removal for re-injection if required.[French]
Un bouchon pour sceller des orifices d'injection dans des éléments en béton comprend un boulon entièrement fileté, un dispositif d'ancrage fileté conçu pour entrer en prise avec un filetage interne de l'orifice d'injection et pour retenir le bouchon de manière sûre sous haute pression, et un joint en caoutchouc dilatable agencé entre deux rondelles coniques. Le serrage d'un écrou sur le boulon comprime le joint en caoutchouc dilatable entre les rondelles coniques, amenant le joint à se dilater radialement contre la paroi de l'orifice d'injection pour empêcher une fuite d'eau et former un dispositif d'obturation étanche à l'eau. La conception permet une installation rapide, un positionnement prévisible, une étanchéité fiable même sous une pression d'eau élevée, et un retrait ultérieur pour une réinjection si nécessaire.
