Abstract

The ready-made concrete shaft has a double-walled sealed pipe (4) in at least one wall opening. The pipe has a concrete outer and a plastics inner liner, the end of which is held inside the shaft opening. The inner liner is exposed over a sealing section and the concrete outer pipe projects into the shaft wall opening by a shorter distance than the exposed section. This opening has a plastics sleeve which converges from the outside to the shaft inside in at least three steps, forming a compatible socket with a shoulder for the pipe end. At least one sealing ring fits between the sleeve and the pipe. The shaft has a plastics inner liner (2).
