Abstract

L’invention concerne un appareil et un système de mesure d’affaissement du sol. L’appareil selon l’invention comprend une unité de détection de champ magnétique, un micro-ordinateur et une unité de charge. L’unité de détection de champ magnétique comprend une pluralité de capteurs de détection de champ magnétique espacés les uns des autres par un écart prédéterminé. Le micro-ordinateur calcule le volume d’affaissement du sol en fonction du signal de détection de champ magnétique émis par l’unité de détection dans les cas où un capteur de détection de champ magnétique parmi une pluralité de capteurs est changé. Et l’unité de charge est chargée avec l’unité de détection de champ magnétique et le micro-ordinateur. Le système selon l’invention comprend un appareil générateur de champ magnétique, un appareil de mesure d’affaissement du sol et un enregistreur de données. L’appareil générateur de champ magnétique est disposé à un emplacement prédéterminé sur le sol, de sorte à être adjacent au trou de travail foré dans une couche non meuble et il génère un champ magnétique. En outre, l’appareil de mesure d’affaissement du sol comprend une extrémité fixée au niveau de la couche non meuble à travers le trou de travail et il mesure le volume d’affaissement du sol en fonction du changement d’emplacement de l’appareil générateur de champ magnétique. L’enregistreur de données reçoit le résultat de mesure de l’appareil de mesure d’affaissement du sol et stocke le résultat reçu. La configuration selon l’invention permet d’effectuer de façon intégrée la mesure du volume d’affaissement d’une surface de sol et le volume d’affaissement de chaque couche de sol au moyen d’un système unique et d’améliorer la précision de la valeur mesurée.
