PERI supplies advanced engineering support to the project
Building the telescope requires advanced technical knowledge. The main mirror consists of 798 individual, movable hexagonal mirrors, which ensure that the mirror shape corresponds to an optically ideal shape at every temperature and inclination of the telescope. Before the light even reaches the cameras, it is detected via a further mirror, which can be deformed using almost 6,000 adjusting elements and thus compensates for air turbulence. This is supported by six “artificial stars”, which are projected by laser into the atmosphere at a height of around 90 kilometres. The complete structure will weigh 3,700 t after completion.
PERI also contributed to a speedy construction process by engineering the simplest possible assembly solutions. PERI engineers reacted quickly and effectively to special, ad-hoc project requirements and aligned the construction site planning accordingly was also essential. PERI also provided support from a commercial and logistical point of view and made a further contribution to efficient construction site execution.
High pressure and load absorption
The foundations for the telescopic structure were laid back in 2018 using the lightweight Handset Alpha panel formwork. TRIO Panel Formwork was used for the massive wall superstructures that now carry the steel structure of the enormous telescopic dome. The 2.40 m x 2.70 m TRIO Panels were designed for the large volume of concrete and the associated high concrete pressure. Almost in parallel, a complex shoring structure grew upwards with the help of ST 100 Stacking Towers to support the loads of the cantilevered platform above.
The shoring was erected and dismantled using the stacking principle, whereby the individual frames were quickly and easily assembled without bolts or screws. By combining the Stacking Towers with components from the PERI UP Scaffolding Kit, the accesses to the platform above could then be created.
