Concreting tunnel A2 Maastricht
The Avenue2 building consortium has poured the first concrete walls and decks on the Europaplein construction section.
The four concrete walls are approx. 6 metres high and have a section length of 24 metres. They form part of fully hydraulically adjustable and self-moving steel wall and flying formwork of Hendriks precon. This wall formwork is centred by the concrete only once.
During the pouring process, engineers of Hendriks precon measured the pouring height and any centre pin loads every half hour. The loads correspond with calculations made in advance.
After the formwork was stripped, the smoothness of the concrete wall was measured and it fully complies with the required B1 category of Cur 100. The formwork for the N2 tunnel is currently being set up at the construction site.
