Construcción del Puente de Rande

Construcción del Puente de Rande

Overview of Construction Techniques

Introduction to the Project

  • The discussion begins with a reference to lighting and its implications on construction, hinting at the importance of visibility in work environments.
  • Mention of "the terrace of workers" suggests a focus on worker conditions and safety during construction activities.

Key Construction Elements

  • An auspicious job is referenced, indicating that certain tasks are deemed significant or fortunate within the context of construction.
  • Discussion about police information related to bridge construction highlights regulatory aspects and potential legal considerations in large projects.

Technical Specifications and Challenges

Structural Details

  • A team managed to achieve specific horizontal vertical measurements for concrete structures, emphasizing precision in engineering.
  • The total volume of concrete used was 17,500 cubic meters, showcasing the scale of materials involved in such constructions.

Material Characteristics

  • Description of how main rows were built from base to coronation with a decal layer indicates advanced layering techniques for structural integrity.
  • Two-piece decal layers made from paper were utilized due to their unique characteristics, suggesting innovative material use in modern construction practices.

Innovative Bridge Design Concepts

Modular Approach

  • The project involves suspended modules being assembled over existing platforms, reflecting modern engineering methods that prioritize efficiency and safety.
  • Historical context is provided regarding bridge design evolution since the 1950s, highlighting advancements in materials like metallic components for better load management.

Engineering Systems

  • The bridge's design incorporates a platform based on successive modules weighing up to 18 tons each, demonstrating careful planning around weight distribution.

Construction Overview of the Main Cables

Main Cable Operation and Structure

  • The operation involved constructing large towers using polyethylene lines from the top, culminating in a completed first-dead tower.
  • Upon completion, significant attention was given to a powerful gap in the tablet, which consisted of a 21-meter-long module.

Navigation Protection Features

  • Navigation safety is ensured by eight windows: two above-cars for potatoes and four above-cars for Alva.

Structural Components

  • The Alva's dukes feature a mattress made from pre-packed concrete at the river's background, supporting various biola lengths (12m, 13m, 5m, and up to 17m).
  • An 8-dead tower was mounted with weights of 65 tons each.

Facilities and Equipment Used

  • Key facilities included three plants capable of processing 25 tons per hour and two sensors with a load capacity of 1,000 kg at heights of 120 meters.
  • Additional equipment comprised remote-like devices weighing up to 350 tons and multiple platforms totaling around 1,200 tons.

Quality Control Measures

  • Highlighted were the controls utilized by various institutes including the Ministry of Public Works and National Institute of Space Technology for quality assurance.
  • Sensitive vehicles are employed to manage photographic documentation points effectively.

Temperature Adaptation Process

  • The Earth was adjusted to meet required temperatures; tests were conducted at night under approximately 18 degrees Celsius.

Final Testing Procedures

  • Longitudinal long-term tests were performed on final components; temperature adjustments were made before mounting feet using existing air.

Significance of the Edge Bridge

Global Importance

  • The edge bridge stands as one of the largest light structures globally among autopists' sources for four circulations not only in Spain but worldwide.

Project Achievements

  • Acknowledgment was given to participants whose dedication ensured safety measures were upheld without any deadly accidents during construction.

Cliente: Autopistas del Atlántico, Concesionaria Española, S.A. Fecha de finalización: Noviembre de 1977. Descripción: Constituye una obra singular dentro de la Autopista del Atlántico, que une La Coruña y Vigo, cruzando la ría de Vigo por el estrecho de Rande y evitando dar un rodeo de más de 50 km. por toda la ría. Mide 1.558 m. de longitud total entre el puente metálico más viaductos de acceso. Las columnas que lo sostienen tienen una altura de 148 m. sobre el fondo marino. El puente en su tramo central es del tipo atirantado. Consta de un tablero metálico con un ancho total de 23,46 m., que permite una doble circulación en cada sentido y que se encuentra a una cota de 50 m. sobre el nivel del mar. La luz libre entre las pilas centrales es de 400,14 m., que lo situaron en su momento en el segundo con más luz del mundo para ese tipo de puentes, entre las pilas centrales y las de tierra hay un tramo de 147,42 m. a ambos lados, dando un total de longitud para el puente central atirantado de 694,98 m. El tablero está suspendido de cables rectos anclados en los bordes del mismo y en las cabezas de las pilas centrales. Las pilas centrales de hormigón armado tienen un altura de 128,10 sobre el nivel del mar y descansan sobre unas fundaciones que llegan a la cota menos 20, cimentadas directamente sobre la roca del fondo de la ría. El conjunto se completa con dos viaductos de acceso, formados por dos vigas de cajón continuas, una por cada calzado, de hormigón pretensado. La longitud total de los viaductos es de 863 metros. Los autores del proyecto fueron Florencio del Pozo, Fabrizio de Miranda y Alfredo Passaro. En 1979 obtuvo el Premio Europeo a la Construcción metálica más destacada.
