Abstract

L'invention concerne un dispositif de drainage de pont qui est installé sur les deux côtés d'un pont pour drainer l'eau de pluie, l'eau de nettoyage, etc., accumulées sur la partie inférieure du pont. Le dispositif de drainage de pont empêche que la partie extérieure du dispositif de drainage enterré dans une plaque supérieure du pont ne se détache de la surface de contact en béton du fait des changements de température, des chocs, des vibrations, etc., entre la surface extérieure du dispositif de drainage et la surface de contact en béton. En conséquence, le dispositif de drainage de pont empêche l'eau de pluie et l'eau de nettoyage de pénétrer dans une fente entre la surface extérieure du dispositif de drainage et la surface de contact en béton. De ce fait, le dispositif de drainage de pont empêche l'écoulement de l'eau de pluie vers le bas de la surface extérieure du tube de drainage, et la corrosion ou l'érosion de la partie inférieure de la plaque supérieure du pont, des poutres d'acier et des montants de pont. Le dispositif de drainage de pont de l'invention comprend : un composant externe doté d'une surface externe qui est rugosifiée pour être en contact avec le béton de la plaque supérieure (1); une couche de résine (39) qui recouvre la surface externe rugosifiée du composant externe ; et du sable (40) étalé sur la couche de revêtement de résine (39), ce qui renforce la force de liaison entre la surface du composant externe et le béton de la plaque supérieure (1).
