Abstract
(EN)
The present invention relates to the field of civil engineering, and relates to a geogrid prepared from a recycled and treated medical waste, a preparation method therefor and an application thereof in foundation reinforcement. The preparation method comprises: recycling a part of medical waste, treating and then processing same into crushed materials, adding a modified filler and a processing assistant, selecting high-strength fiber bundles to be compounded and molten with the mixture, pressing, and stretching to prepare a geogrid. The part of the medical waste is one or any combination of multiple used medical plastic products and expired and unused medical plastic products. The high-strength fiber bundles are more than one bundle of fiber materials which are commercially available for manufacturing geogrids. The modified filler is a stabilizer for improving the stability of the components to heat and light. The processing assistant is a reinforcing agent for improving the performance of the components. The present invention innovatively solves the problem that it is difficult to treat the part of the medical waste, and creates more economic benefits and social benefits while reducing the waste pollution and protecting the environment.
(FR)
La présente invention relève du domaine du génie civil, et concerne une géogrille préparée à partir de déchets médicaux recyclés et traités, son procédé de préparation et son utilisation dans le renforcement des fondations. Le procédé de préparation comprend : le recyclage d'une partie de déchets médicaux, le traitement puis la transformation de ceux-ci en matériaux broyés, l'ajout d'une charge modifiée et d'un auxiliaire de traitement, la sélection de faisceaux de fibres à haute résistance devant être mélangés et fondus avec le mélange, le pressage et l'étirement pour préparer une géogrille. La partie des déchets médicaux est une ou n'importe quelle combinaison de multiples produits plastiques médicaux utilisés et de produits plastiques médicaux expirés et non utilisés. Les faisceaux de fibres à haute résistance sont au moins un faisceau de matériaux fibreux qui sont disponibles dans le commerce pour la fabrication de géogrilles. La charge modifiée est un stabilisant destiné à améliorer la stabilité des composants à la chaleur et à la lumière. L'assistant de traitement est un agent de renforcement destiné à améliorer les performances des composants. La présente invention résout de manière innovante le problème selon lequel il est difficile de traiter la partie des déchets médicaux, et crée des avantages sociaux-économiques tout en réduisant la pollution des déchets et en protégeant l'environnement.
