Tunnel and Risers Construction

SRK Argentina assisted the client in the construction of a tunnel and risers on the Matanza-Riachuelo project. 

The project consists of a tunnel that is 4.9 m in diameter and 12 km in length that will flush treated water into the River La Plata. The excavation works are located 40 m in the bed of the river using double-shielded TBM. 

This tunnel will be one of the longest of its kind in the world. Since January 2018, several numerical analyses have been completed to check the geotechnical designs, complemented with analysis of monitoring data and CPTu campaigns to advise the client in the early construction stages.
