City railway construction at the Potsdamer Platz in Berlin
In connection with the city railway construction at the Potsdamer Platz, it is necessary to drain ground water. For this the well-diggers sink a tube with the diameter of 50 cm into the ground. Since the workers have encountered in this operation a large block of granite at 13 and a half meters depth, now a worker is lowered through the narrow pipe to remove the obstacle with a jackhammer
