An ice composite body (10) has an inner ice core (11) and a protective outer armour shell (12). The outer armour shell (12) consists of a base section (13), side sections (14) and a separate top section (15), which is free to move vertically between the side sections (14). The inner ice core (11) is maintained in a frozen condition in use by refrigeration pipes (21), which are located at various levels therethrough. The inner ice core (11) is built up from thin layers of ice which are frozen one after the other. Following the freezing of each layer of ice the layer is rolled using a roller apparatus which provides a roller pressure in the range of 3.5 to 8 Newtons/mm2. The ice composite body (10) can be used in warm or cool waters for applications such as bridges, breakwaters, causeways, pontoons, artificial islands, dams, tidal barrages, wave power barrages, harbour walls, wind power farms or aircraft runways.

Cette invention se rapporte à un corps composite en glace (10), qui comprend un noyau de glace interne et une carapace de protection externe (12). La carapace externe (12) est constituée par une section de base (13), par des sections latérales (14) et par une section supérieure séparée (15), laquelle est libre de se déplacer verticalement entre les sections latérales (14). Le noyau de glace interne (11) est maintenu congelé pendant l'utilisation par des tuyaux de réfrigération (21), lesquels sont placés à divers niveaux dans le noyau. Le noyau de glace interne (11) est construit à partir de minces couches de glace qui sont congelées l'une après l'autre. Après la congélation de chacune des couches de glace, celles-ci sont roulées à l'aide d'un appareil à rouleaux qui fournit une pression de rouleau comprise entre 3,5 et 8 Newtons/mm?2¿. Ce corps composite en glace (10) peut être utilisé dans des eaux chaudes ou froides pour des applications telles que ponts, brise-lames, ponts-jetées, pontons, îles artificielles, barrages, digues de marée, barrages pour centrales houlomotrices, murs de soutènement de ports, parcs d'éoliennes ou pistes d'aéroport.
