<p>Method in connection with the production of a container having more than one wall, whereby a first shell (10) is manufactured to a specified form from an impermeable material and is provided with external, protruding, stiffening means (11). A second shell (12) is manufactured having inner dimensions larger than the outer dimensions of the first shell in order to receive the first shell (10), whereafter a hardening concrete material (13) is filled in a space between the first shell (10) and the second shell (12). A device according to the invention comprises a first shell (10) which is made of an impermeable and is given a specified form. The first shell (10) has externally protruding means (11) for imparting rigidity to the shell and a second shell (12), which has been given such inner dimensions that makes it possible for it to receive the first shell (10). A hardening concrete material (13) is contained in a space between the first shell (10) and the second shell (12).</p> |
