Gran Via’s road tunneling Megaproject in Barcelona (Spain)

The project: civil works in the City of Barcelona

Alsina Formwork began last year its collaboration in the construction of the collectors in Plaza de las Glorias in Barcelona, ​​in charge of the client UTE Túnel Glorias.

This phase of the project is to be completed this year 2017 and involves the construction of a 60 meters long vaulted gallery straight section implemented with 7.2 meters long formwork equipment in 10 sets.

This structure is part of the enormous underground project of the Gran Vía and Glories park remodeling in the city of Barcelona, ​​which will at the same time allow the relocation of the plaza’s underground collectors for the subsequent execution of the High speed train tunnels.

Alsina: versatile and effective solutions for the construction of tunnels.

For the implementation of this project AlsiTec (Alsina’s technical department) has designed a tailor-made formwork with standard material from its Multiform and Alisply Vaults formwork systems, light and fast assembly systems that are having a very positive impact on productivity.

The Multiform system, consisting of double UPN metal beams, wooden beams, strips and turnbuckles is one of Alsina’s most versatile systems, allowing “ad hoc” design of the necessary recoverable formwork to adapt to any geometry whether they are straight, curved or one sided walls, lintels or bridge boards.
On the other hand, the circular Alisply Vaults system, has allowed the perfect adaptation to the geometry of the vault with a 2.5 meters radius. This system of circular walls adapted to form vaults is resistant, versatile and compatible with the MultiForm family, which allows equipment’s high profitability at the job site. Alisply system has a phenolic surface, so it offers multiple advantages over metallic surfaces, such as lower weight, higher quality of concrete, increased performance and greater resistance to inclement weather.
