Of course, theming was also very important to us in this construction phase. Without the typical ‘Plohn style’, things would not work here. The tunnel to the mine is getting its first expensive accessories: turbine, transmission shaft, water wheel, steam engine, all decorative elements brought together in keeping with the style and in loving detail from the whole of Germany. So our construction site enters its summer break. In the holidays there are no longer any limitations from construction work. In Autumn things will get rolling. We will keep you updated.
Up next is the beginning of construction for our railway station. This means: Base layer of concrete up to the rocks, deeper foundation, then cleanliness layer. Then we proceed with applying the concrete to the top and cladding the walls. The side walls for the marshalling yard for the maintenance hangar are already in progress.
The construction of the individual foundations presented particular challenges due to the particular soil properties at first. But now swift progress is being made. The foundations for the looping are on the agenda, with the enormous centrifugal forces in curves and looping, stability must be guaranteed in all directions. The support wall for the tracks provides additional stabilisation.
We are well on schedule. The construction of the tunnel to our German premiere is making progress in leaps and bounds: The tunnel roof has already been clad. The next step is the completion of the concrete layer for the top. On the way to Westernplatz you can already see the impressive tunnel construction.
We now move on to building more than a hundred individual foundations, the foundation stones for the subsequent track route of our premiere in Germany. Each foundation will be given its own support shape depending on the respective precise load of the foundation. An unbelievable amount of power is released in Dynamite’s sharp curves. Each foundation is dug after being examined and recorded separately.
Caution: explosive substance! Germany’s first Big Dipper Coaster isn’t the only thing that’s going to be explosive: the roughly 120 individual foundations cannot be built without dynamite. The bedrock surface is higher in some places in the area of the former silver mine, due to which blasting is necessary. Several boreholes are being made and around 350 m³ of rocks blasted. The sound of the huge explosion resonates through Plohn and its surroundings.
The construction of the tunnel for our new major attraction is beginning to take shape. The walls are being built and put up, which will be followed by the ceiling formwork and the casting of the ceiling. The tunnel will be an impressive 7 metres wide, 7 metres high and approx. 25 metres long for Dynamite. Stability is our highest priority because there is still more to be done to the tunnel - we’ll keep you guessing.
Now comes the construction of the foundations. In order to guarantee 100% stability each individual footing has to be put in place right to down to the rock 7 metres deep, including 6 metres of oversite concrete. Every frost-free day is used, in order to maintain the production schedule.
The construction work on the tunnel begins. A total of more than 200 tons of steel is used, as reinforcement for the foundations, among other things. The floor slab for the tunnel alone devours some 300 m³ of concrete.
The preparatory earthworks for the tunnel begin. Enormous masses of earth have to be moved and transported away for this purpose.
The access to the construction site has been prepared and new space created. A few preparations for earthworks up to 7 metres deep are needed, before things can finally get started.
Goodbye Silvermine: our venerable roller-coaster is going to a well-earned retirement. It will be divided into individual segments. Possibly one part of it or another will turn up in a new location in the park, who knows?
