WATCH: Herrenknecht TBM emerges in the Netherlands
The first tunnel tube for COMOL5’s Rijnland Route in the Netherlands has been completed by tunnel boring machine (TBM) Gaia.
Since launching in August 2019 from the starting point at the A4 motorway in Katwijk, the TBM has excavated a total of 2,250 m to complete the first tunnel tube of the RijnlandRoute.
In late January, Herrenknecht’s TBM Gaia arrived under water after six months of drilling in the receiving shaft.
COMOL5 has released a time lapse demonstrating how the water is pumped away as the machine slowly becomes visible.
Over the coming weeks the cutter wheel and the front sections of the machine will be disassembled and transported back to the start shaft to commence excavating the second tunnel in April.
