The lower end of an outwardly tight shaft structure (3) for a bore shaft (1) rests on a tilting joint arrangement (15, 20). This arrangement includes a hydraulic thrust bearing (15) at the end face of the shaft structure (3) and a hydraulic annular cylinder (20) at the circumference of the lower end of the shaft structure (3). Thus, this tilting joint arrangement (15, 20) is located between the shaft structure (3) and the base (10) and permits tilting of the shaft structure (3) relative to the ground (12) without impairing the water-tightness of the bore shaft foundation.
