Geotechnical plans for the construction of Mexico City’s new General Canal drainage tunnel have been announced by the joint venture contractors.
The contract for the General Canal drainage tunnel was awarded by the national water commission Conagua earlier this year to a consortium comprised of Ingenieros Civiles Asociados (ICA) and ICA subsidiary Construcciones y Trituraciones.
An earth pressure balance tunnel boring machine will be used for excavation ahead of installation of a pre-cast concrete segmented lining. The project also includes construction of four shafts to depths of around 25m.
Construction of the 8km long and 5m diameter tunnel under the Chalco valley will start in February next year and work is expected to finish in March 2017.
The tunnel will be excavated parallel to the General Canal, from the Parada del Toro pumping station to the La Caldera pumping station.
Recent flooding around Mexico City has prompted an investment in a number of ground engineering projects, including the $MXN1.14bn (£51.4M) General Canal drainage tunnel. The tunnel forms part of a wider programme to reduce the risk of flooding in the area and to remediate the Tláhuac Xico lagoon.
