Technical installations installed in service building corbulo tunnel rhine route

It involves 54 different installations that ensure a safe tunnel, such as the lighting, cameras, emergency phones and the fire alarm system. The installations, built up in a total of 24 modules (containers), have been assembled and extensively tested at the test site in Eindhoven over the past two years. Especially for the transport from Eindhoven to Leiden, the modules are packed dust- and waterproof and are hoisted into the service building according to a fixed schedule.

Teething

By building the tunnel technical equipment modularly in advance, teething problems are already eliminated at the test site, which saves a lot of time later on. With this modular working method, the test work in the tunnel is significantly reduced to mainly physical tests, which can actually only take place in the tunnel.

Benjamin Mooijaart, project manager VTTI Comol5 is proud of this special milestone: "A requirement of the client was that all TTIs had to be tested 2 years before opening. With this way of working, we went one step further in that". Piet Jansen, TTI project leader Province of South Holland agrees: "This milestone in the project is icing on the cake. Our strategy from 2015 to bring tested systems to the tunnel 2 years before opening has succeeded. We reviewed everything on paper and tested it in Eindhoven, and now it is reality."

Furnishing service buildings

16 of the 26 modules are currently being installed in the service building on the east side near the A4. The remaining 10 modules will move to the service building on the west side near the A44 over the summer. The modules are being lifted from the trucks into the service building, to the first floor and -1 level. This has to be done in a certain order. Fireproof walls are also placed between them. Once everything is in, the roof can be put on.

Connecting cabling & on-site testing

The next step after installing the modules is to connect all the cabling. The installations are connected via a cable duct under the road surface where there are niches with technical cabinets every 50 meters. These cabinets are connected to the service buildings and to the components in the tunnel. Laying all these connections will take at least another year, after which the testing will take place and the permit will be applied for. According to the current planning, the Corbulo tunnel will open to traffic in 2023.

Scoop: connected to Rhoon traffic center three years before opening

Over the past two years, all installations were built and tested at the test site in Eindhoven. No less than three years before opening, the tunnel technical installations of the RijnlandRoute were already connected to the traffic control center in Rhoon. A first in the tunnel world!

In Eindhoven, all tunnel technical installations (TTI) are fully conditioned built and tested. Here the TTIs and modules are prepared for transport and installation at their final destination in the service buildings (plug & play). The modules are packed dust and watertight for transport.
