ABSTRACT:
Flexible pipes unwound from a supply drum are placed adjacent a wall to be supported, and water is applied to the outside of the pipes while passing through them a cooling medium at a temperature below the melting point of ice, thereby freezing a first ice layer against the wall. Cooling medium at a temperature above the ice melting point is then passed through the pipes to loosen them from the ice; and at least some of the pipes are rewound on the drum to remove them from the first ice layer and are then replaced outside but adjacent thereto, after which the procedure is repeated until enough ice layers are formed to provide a block of desired thickness.
