Execution
Approximately 1,640 meters in total have been piled with our Junttan PMX22.
The lengths were ordered in 13 meter lengths of the type P270 T8. Most
the piles were joined when the average length was around 22-23 metres.
In the picture you can see that a PDA measurement has been carried out. This in order to
ensure that the pile has sufficient and correct support in relation to the design.
It was also drilled vertically with micropiles (ishebeckstag). Reason
for this the risk of using concrete piles and the tremors was this
entails next to old concrete pipes that should still be in
operation.

The micropiles are drilled down with a Klemm 806-5G rig
top hammer. At the same time as drilling down, slurry is pumped
into the hole space in the center of the pile, out of the hole in the pilot and mixes
with the masses heading down.
