Abstract

L'invention concerne un coffrage de pile de pont de chemin de fer de type à rainure pouvant être rapidement assemblé et démonté. Le coffrage de pile de pont de chemin de fer de type à rainure comprend un panneau de coffrage (1), une plaque de renforcement horizontale (2), une plaque de renforcement verticale (3) et des trous de liaison (4), dans lequel la plaque de renforcement horizontale (2) est agencée au niveau du bord horizontal du panneau de coffrage (1), la plaque de renforcement verticale (3) est agencée au niveau du bord vertical du panneau de coffrage (1), la plaque de renforcement verticale (3) comporte une rainure, et la plaque de renforcement horizontale (2) comporte une rainure correspondant à la plaque de renforcement verticale (3) ; et les trous de liaison (4) sont mis en œuvre de manière uniforme dans la plaque de renforcement horizontale (2) ou la plaque de renforcement verticale (3). Le coffrage de pile de pont de chemin de fer de type à rainure peut considérablement augmenter la vitesse et la précision de l'assemblage sur place des coffrages de pile de pont de chemin de fer, et pendant le démontage, un effet de libération de contrainte se produit au niveau d'un assemblage de couture verticale, de telle sorte que les coffrages sont automatiquement divisés, ce qui permet des économies d'investissement en termes de travail et d'équipement.
