INDUSTRY, INNOVATION AND INFRASTRUCTURE
Build resilient infrastructure, promote sustainable industrialization and foster innovation
Economic growth, social advancement and action against the climate emergency depend largely on investment in infrastructure, sustainable industrial development and technological progress. Today, about 1 billion people live more than 2 km from a roadway, 940 million live without electricity, and 663 million lack improved drinking water sources.
ACCIONA participates in the entire infrastructure construction value chain, from the identification of opportunity, design and execution, to the operation and maintenance of the constructed works, using the most advanced and innovative techniques.
Performance quality and safety are two of the criteria that maximize the company's value proposal in the development of large infrastructure projects and that differentiate it from other competitors in the construction field.
SUSTAINABLE CITIES AND COMMUNITIES
Make cities and human settlements inclusive, safe, resilient and sustainable
Today, cities represent 3 % of the planet's surface and concentrate more than 50 % of the population. A figure that will rise to 70 % by 2050. In addition, cities generate more than 80 % of the world's gross domestic product (GDP).
In addition to facilitating access to essential services for life - such as energy and water - ACCIONA contributes to making cities places of productive well-being in which to live, favouring people's socio-economic development.
The section has two distinct parts. The first is the open subsection between the origin of the project established at k.p. 2/200 from the parking lot defined in the survey report, which meets the junction with Buenos Aires Street, and the entrance of the false tunnels preceding the tunnel, formed by two twin tubes for a single track.
The second part consists of this tunnel subsection whose exit is near the end of the section and at the origin of the next section, and which constitutes the main part of this project.
The most significant features of the project include the construction of:
- Two twin tunnels that are extended at their ends by false tunnels.
- On the Vigo side, these tunnels meet under the A-9 Highway through a section between cut-off walls, constructed with a 'cut-and-cover' method.
- There will be galleries between both tunnels built every 250 m, excavated using conventional methods.
