The Project
Impressions from the project process
The Algerian metro station "Place des Martyrs" is 144 m long and features record-breaking dimensions with its 23 m width and 14.80 m height.
Based on the VARIOKIT modular system, the PERI formwork carriage solution is tailored to meet all project requirements and is also hydraulically operated.
Shuttering and stripping is done hydraulically on the VARIOKIT tunnel formwork carriage. It is also based on rentable system components and can be rapidly assembled and adapted by means of standardized bolted connections.
PERI engineers created a formwork carriage construction on the basis of the VARIOKIT engineering construction kit. Using the same system components and formwork segments, both cross-sectional metro station variants can be cost-effectively realized.
The PERI UP working scaffold has been optimally adapted to suit the imposing cross-sectional geometry of the station´s arched form and is used to execute the waterproofing and reinforcement work in advance.
A total of four PERI tunnel formwork carriages are being used: in addition to the VARIOKIT formwork carriage construction for the "Place des Martyrs", a second project formwork carriage with a 9.30 m radius is being utilized for the realisation of the "Ali Boumendjel" intermediate station.
Project Information
Rui Correia
Technical Manager
The VARIOKIT system played a key role in mastering the challenges presented during the construction of the station - the PERI formwork carriage adapted perfectly to suit the different geometries. With the fast concreting cycle sequence of 15 m per week, the project could be completed ahead of schedule in spite of the high technical and quality requirements.
