Abstract

La présente invention se rapporte à une installation d'entreposage (10) destinée à l'entreposage de matériaux en vrac, tels que des céréales, en une réserve (11). L'installation d'entreposage (10) comprend une cloison (15) installée sur une base (16). La cloison (15) comprend une structure de paroi périphérique (17) qui délimite une zone d'entreposage (19) dans laquelle la réserve (11) peut être créée sur la base (16). La construction de la structure de paroi périphérique (17) est modulaire, comprenant une pluralité de modules de paroi latérale (25) qui sont conçus pour être assemblés ensemble et dont certains sont équipés d'ensembles rouleaux (33). Une bâche de protection amovible (90) est utilisée pour recouvrir la réserve (11). La bâche de protection (90) comprend une pluralité de feuilles couvrantes (91) conçues pour être disposées de manière adjacente les unes aux autres et reliées ensemble de façon amovible au niveau de bords adjacents. Les feuilles couvrantes (91) ont chacune un état plié et un état déployé pour s'étendre sur la zone d'entreposage (19) afin de recouvrir la réserve (11). Chaque ensemble rouleau (33) comprend un rouleau (10) autour duquel une feuille couvrante respective (91) peut s'enrouler entre les états plié et déployé. Un système de liaison destiné à relier de façon amovible les feuilles couvrantes adjacentes (91), lorsqu'elles sont dans l'état déployé, est également décrit et revendiqué.
