Abstract

L'invention concerne un véhicule de nettoyage pour tunnel, comprenant un groupe propulseur (13), un réservoir à liquide de lavage (8) et une unité de nettoyage, reliée au réservoir à liquide de lavage (8) par le biais de conduites d'arrivée (5), et pourvue de brosses de nettoyage (3) et de buses de nettoyage (4) destinées à délivrer le liquide de lavage cotre la paroi intérieure du tunnel. Selon l'invention, une unité d'aspiration pour le liquide de lavage souillé est présente, laquelle est reliée à un réservoir de sédimentation (6) destiné à la pré-épuration du liquide de lavage souillé, et le réservoir de sédimentation (6) est relié par le biais d'une conduite d'arrivée (9, 15) pour le liquide de lavage pré-épuré à une unité de conditionnement (11) pour le liquide de lavage pré-épuré, laquelle comporte un étage de floculation (16) et un étage de sédimentation (17) monté à la suite de l'étage de floculation (16). Une conduite de retour (10) pour le liquide de lavage épuré mène de l'unité de conditionnement (11) dans le réservoir à liquide de lavage (8). Le véhicule de nettoyage selon l'invention prévoit ainsi non seulement la collecte et le conditionnement du liquide de lavage souillé, mais également sa réutilisation pour le nettoyage du tunnel, ce qui permet de réaliser un nettoyage plus rapide et plus économique des parois intérieures d'un tunnel.
