Metro Line M4 – Milan
Client:
M4BLU
Place and date:
Italy – Milano. 2017 – ongoing
Services:
Static test on stations and geophysical surveys.
The M4 or “Blue Line” will connect the historic center with the eastern part (Q.re Forlanini and Linate Airport) and the western part (Q.re Lorenteggio and Stazione San Cristoforo), integrating the urban transport network with a new solution fast, efficient, comfortable and non-polluting.
The construction of the line consists of 21 stations on approximately 30km of tunnels.
Akron carries out all the tests (static load tests) for the tests related to the 21 stations. The tests are carried out with the application of loads in different ways: weights, trucks, push and pull jacks (up to 15 points of pulling or pushing). Lowering measurements are performed with electrical displacement transducers up to a maximum of 30 measurement points per test.
During the various phases of construction of tunnels and stations, when particular problems arise, Akron intervenes in the diagnostic field with geophysical methods (checks on the yield of consolidations, surveys on the back of tunnel coverings, etc.) and with non-destructive testing on structures.
