false tunnel in Rzeszów

Tunnels and Bridges
WE HAVE high-resolution capability to effectively address the needs of all our customers.

Alsina’s Formwork Polish subsidiary participated in the construction of a false tunnel in the city of Rzeszów (Poland) in order to carry out a pedestrian passageway for the local community under a highway.

The construction was carried out on a plot with a 4% inclination and was implemented by using a just 5 stepping process of the Alsina’s Alisply Circular system, which had a very positive impact on the client’s impression and their experience with the system and formwork process created by Alsina.

Alsina: safe and effective formwork solutions for civil works

For the implementation of the project, Alsina supplied its Alisply Vaults system,  Multiform formwork system and AR-80 Shoring system.

Circular Alisply Vaults system allows 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.

On the other hand, Alsina’s 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.
