Viaducto Zumelegi, Elorrio, España - ULMA Construction [es]
El viaducto de Zumelegi forma parte de la plataforma de alta velocidad que conectará las tres principales ciudades del País Vasco. Conocida como “Y Vasca” por su geometría, tendrá tres ramas y un nudo central de enlace ubicado en este mismo punto. ULMA ha ofrecido soluciones de encofrado y cimbra para la construcción de la estructura del viaducto de 481 m de longitud. Las soluciones ofrecidas se han adaptado a las necesidades del cliente. En el diseño del proyecto se ha priorizado la reutilización del material al máximo y la reducción del plazo de ejecución. Así tras cada hormigonado, la cimbra y el encofrado se han trasladado a la siguiente puesta mientras el tablero quedaba apeado con una sola torre. Las 6 pilas que componen el viaducto alcanzan una altura máxima de 71 m por lo que la seguridad y el rendimiento es fundamental a la hora de seleccionar los equipos. El sistema autotrepante ATR y los paños de encofrado ENKOFORM V-100, han conformado un conjunto cerrado perimetralmente, que se ha elevado de forma hidráulica y autónoma sin depender de la grúa, adaptándose al cambio de geometría en cada tongada. Los dos conjuntos de encofrado interior se han apoyado sobre plataformas telescópicas KSP para absorber las variaciones de la geometría de la pila.

Known as the "Basque Y" due to its geometry, it will have three lines and a central junction located at the same point. ULMA has provided formwork and shoring solutions for the construction of the 481 m long viaduct structure. The solutions offered have been tailored to the customer's needs. When designing the project, priority was given to reusing the maximum amount of material possible and reducing on-site deadlines, so after each pouring, the shoring and formwork were moved to the next pouring while the deck was shored with a single tower. The 6 piers that make up the viaduct reach a maximum height of 71 m, so safety and performance are fundamental when selecting the equipment. The ATR self‑climbing system and the ENKOFORM V‑100 formwork panels formed a perimeter-closed assembly, which was hydraulically and autonomously lifted without depending on the crane, adapting to the change of geometry in each pour. The two interior formwork assemblies were supported on KSP telescopic platforms to absorb the variations in the geometry of the pier.
