After 13,5 month of tunnel advance in Antwerp underground the south TBM arrived in the reception shaft of KW11 16.05.2011.
The TBM started 31st of March 2010 to drill a 6km long freight train tunnel, passing the Scheldt river and the Kanaaldok B1-B2. Due to a very good performance, the 1st TBM is about 6 weeks ahead of schedule. In total 2 shield driven TBM tunnels are under construction with a diameter of 8,1m. The tunneling of the northern tube is still ongoing; arrival is expected by end of July.
The tunnel construction works are to be done by the tunneling specialists of French Vinci Grands Projets Construction and German BAM subsidiary Wayss & Freytag Ingenieurbau AG. Belgian companies MBG and BAM CEI-DeMeyer are responsible for the civil works of the project with a total length of 16.2km. The project has to be completed in July 2013.
As shown on the photo, the TBM passed a softeye of 9,0m diameter in a 1,50m thick diaphragm wall provided with gfrp-bars of the german supplier SCHÖCK.
