  • These shaft elements usually consist of concrete rings, which are provided on the end face with recesses and projections for mutual securing of the position and which are usually equipped with a climbing aid to enable people to climb down the shaft.
  • This climbing aid consists either of individual climbing elements, for example of metal pipes or rods, the ends of which are built into the concrete during the manufacuring process of the manhole elements, or of climbing ladders or ladder parts, which are usually retrofitted to the wall of the manhole elements that have already been completed assembled shaft are fastened by means of suitable fasteners.

These fixing devices enable the climbing aid to be attached in a desired, predetermined position without additional aids, while at the same time protecting the inner wall of the concrete or the like. existing basic body. There is therefore no need for any special formwork means which are only required for fixing the climbing aid and whose removal from the form by the fixed climbing aid is tedious.
  • the fixing devices can, for example, be bowl-shaped receptacles for parts of the climbing aid.
  • openings are provided in the plastic lining, in which projections of the climbing aid are inserted. These openings allow the projections and thus the climbing aid itself to be securely fixed and prevent the climbing aid from being removed unintentionally.
  • the openings preferably penetrate the wall of the plastic lining, the projections projecting into the base body and being anchored therein.
  • the plastic lining forms, at least in connection with corresponding supporting or spreading devices, the formwork during the manufacture of the base body and the base body takes over at least the majority of the forces occurring when climbing the climbing aid, so that the plastic lining can be dimensioned weaker in this embodiment .
