Title (EN) MANHOLE COVER TRANSPARENT TO RADIOFREQUENCY SIGNALS
(FR) COUVERCLE POUR CHAMBRE DE VISITE TRANSPARENT VIS-À-VIS DES SIGNAUX RADIO-FRÉQUENCE
Abstract:
(EN) The invention relates to a manhole cover, said manhole being provided with an access opening and being suitable for containing a device for transmitting a radiofrequency signal, said cover comprising a wall (1a) intended for covering said access opening when the cover is in closed position, characterised in that the wall of the cover is bored by at least one through-opening (OC) filled with a sealing material (ME) of the cover, said material extending over the surface of the wall of the cover that is oriented towards the inside of the manhole when the cover is in closed position, said material being made up of a material that is transparent to the propagation of a radiofrequency signal transmitted from and/or to the transmission device.
(FR) L'invention concerne un couvercle pour chambre de visite, ladite chambre étant pourvue d'une ouverture d'accès et étant adaptée pour contenir un dispositif de transmission de signal radio fréquence, ledit couvercle comprenant une paroi (1a) destinée à recouvrir ladite ouverture d'accès lorsque le couvercle est en position fermée, caractérisé en ce que la paroi du couvercle est percée d'au moins une ouverture traversante (OC) remplie d'un matériau d'étanchéité (ME) du couvercle, ledit matériau s'étendant sur la surface de la paroi du couvercle qui est orientée en direction de l'intérieur de la chambre de visite lorsque le couvercle est en position fermée, ledit matériau étant constitué d'une matière transparente à la propagation d'un signal radio fréquence transmis depuis et/ou vers le dispositif de transmission.
