Abstract

La présente invention concerne une feuille résistante à l'eau disposée pour la résistance à l'eau pendant une construction de tunnel. La feuille résistante à l'eau selon la présente invention possède la structure la plus simple possible et est utilisée pendant une construction de tunnel afin d'évacuer doucement l'eau drainée par la face de déblaiement du tunnel. La feuille résistante à l'eau comprend : une première feuille résistante à l'eau formée d'une matière PE souple qui empêche l'eau de pénétrer ; au moins une lame fixe dont une extrémité est fixée par fusion sur la surface supérieure de la première feuille résistante à l'eau dans les directions avant et arrière ; et une partie concave-convexe ayant plusieurs saillies qui dépassent en continu et de manière répétée dans les directions avant et arrière et les directions gauche et droite sur la surface supérieure de la première feuille résistante à l'eau sur laquelle la lame fixe est fixée par fusion, de manière qu'un espacement constant soit maintenu entre la face de béton projeté du tunnel et la première feuille résistante à l'eau, et que l'eau drainée par la face de déblaiement du tunnel puisse être évacuée.
