Title
(EN) SARDINE-BONE CONSTRUCTION METHOD FOR LARGE-SECTION TUNNEL
(FR) PROCEDE DE CONSTRUCTION EN ARETE DE SARDINE POUR TUNNEL DE GRANDE SECTION
Abstract
(EN)
A method of boring a large-section tunnel safely and quickly by reinforcing and improving in advance the ground over the full length of the tunnel section, wherein a top drift (2) is bored through the full length of the tunnel (1) section, then curved holes are drilled at preset intervals from the top drift (2) along the peripheral edges of the sections of the tunnel (1) by using rock drills and curved steel pipes (3), the steel pipes (3) are pulled off after injection pipes are inserted into the drilled holes, grout is injected into the ground surrounding the tunnel through the injection pipes to develop artificial ground arches (4), then the tunnel (1) is excavated, suspension forms (6) are advanced and concrete is placed for secondary lining, whereby the tunnel is bored.
(FR)
L'invention concerne un procédé permettant de forer de manière sûre et rapide un tunnel de grande section par renforcement du sol et amélioration de la progression sur toute la longueur de la section de tunnel. On fore une galerie supérieure (2) sur toute la longueur de la section de tunnel (1), puis on fore des trous en courbe à des intervalles déterminés de la galerie supérieure (2) le long des bords périphériques des sections du tunnel (1) à l'aide d'une perforatrice et de tuyaux en acier (3) courbes, lesdits tuyaux en acier étant retirés une fois que les tuyaux d'injection sont introduits dans les trous forés, on injecte du lait de ciment dans le sol autour du tunnel, par l'intermédiaire des tuyaux d'injection afin de produire des arches (4) de sol artificielles, puis on creuse le tunnel (1), on forme des parties suspendues (6) et on y place du béton afin de produire un revêtement secondaire, puis on creuse le tunnel.
