Abstract

L'invention concerne un procédé de traitement combiné de blocage et de drainage pour fuite d'eau au niveau d'un joint de construction d'un revêtement secondaire d'un tunnel. Selon le procédé, l'eau est bloquée au moyen d'un boulon d'ancrage (3) et d'un arrêt d'eau en caoutchouc (5), et l'eau est ensuite évacuée naturellement par l'intermédiaire d'un canal de drainage (6) et d'un tuyau de drainage (9). Le procédé ne change pas la structure actuelle du revêtement secondaire (12) du tunnel et n'est pas très destructif, empêchant ainsi efficacement la fissuration d'un revêtement et n'influençant pas la sécurité et l'utilisation d'un tunnel. De plus, les étapes de construction du procédé sont simples et présentent une opérabilité élevée, et un système combiné de blocage et de drainage est formé pour réaliser un drainage naturel.
