method for backfilling of cavities by means of a stabilized sand mixtures and devices of the transportbetonindustrie

摘要

The invention relates to a method for filling natural or artificial cavities, especially abandoned tunnels, war tunnels, mines or rock crevices, the cavities of a stabilized sand mixture with a sand and / or grain mixture proportion of 5-95% and a resistance between 0, 3 to 7.9 are N / mm2 filled. The production of stabilized sand mixture is carried out with external or erected on site mixing equipment and the transport of stabilized sand mixture by means of truck mixers and / or transport troughs and / or pumps from the ready-mixed concrete industry.
