The shaft container (10), for supply shafts, has an outer concrete container (12) in a beaker shape with an inner container liner (14) of fluid-impermeable plastics in a beaker shape. A space gap (20) is formed between the concrete side wall (16) of the outer container and the lining, to give movement of the lining within the outer container structure in a limited floating range, to prevent damaging tensions and cracks through expansion and contraction on changes of temperature. |
