A first joint (1) between respective prestressed concrete elements (103) is filled. The subsequent joints are filled with a predetermined time delay until all the joints (1-19) are filled. The joints are formed such that the concrete rises in a transcend hole positioned beside the embedded tube going through the elements. The concrete elements are vertically prestressed using cables, and have horizontally embedded tubes for horizontal prestress cables. A ball valve or sliding valve positioned at each joint act as a cut-off valve. An Independent claim is also included for the tank produced. |
