(FR) PÂTE D'ÉTANCHÉITÉ
Abstract:
(DE) Die vorliegende Erfindung betrifft Mischungen, bevorzugt Dichtungspasten, besonders bevorzugt Schildschwanzdichtungspasten und die Verwendung der erfindungsgemäßen Mischungen zum Abdichten von Bauelementen und/oder Baumaschinen, insbesondere zum vorzugsweise temporären Abdichten des Übergang zwischen Schildschwanz einer Tunnelbohrmaschine und der Rohrauskleidung bzw. Tübbingauskleidung der Tunnel Sicherung. Die Mischungen enthalten Schichtsilikate, bevorzugt Bentonit oder Talk; Alkohol mit 1-5 Hydroxylgruppen, bevorzugt Glyckol; Alkalisalz oder ammoniumsalz, bevorzugt ein Carboxylat, Wasser.
(EN) The invention relates to mixtures, preferably sealing pastes, more preferably shield tail sealing pastes, and to the use of the mixtures according to the invention for sealing construction elements and/or construction machines, in particular for the preferably temporary sealing of the transition between the shield tail of a tunnel boring machine and the pipe liner or tubing lining of the tunnel safeguard. The mixtures comprise layered silicate, preferably bentonite or talc; an alcohol having 1-5 hydroxyl groups, preferably glycol; an alkaline salt or ammonium salt, preferably a carboxylate; and water.
(FR) L'invention concerne des mélanges, de préférence des pâtes d'étanchéité, et de préférence encore des pâtes d'étanchéité pour queue de bouclier, et l'utilisation des mélanges selon l'invention pour assurer l'étanchéité d'éléments structuraux et/ou de machines de chantier, en particulier pour assurer l'étanchéité de préférence temporaire de la jonction entre la queue de bouclier d'un tunnelier et l'habillage intérieur de tuyau ou le cuvelage de la mise en sécurité d'un tunnel. Les mélanges renferment des phyllosilicates, de préférence bentonite ou talc; un alcool ayant entre 1 et 5 groupes hydroxyle, de préférence glycol; un sel alcalin ou un sel d'ammonium, de préférence carboxylate; et de l'eau.
