Abstract: Methods of compacting soil, and devices for carrying out the methods are provided in which an underground compacting device is inserted into the soil at a predetermined depth under which the compaction by the upper level of the soil becomes ineffective.
Abstract: The invention relates to the methods allowing to compact the soil, and devices for carrying out these methods. It comprises the insertion into the soil at a predetermined depth (h) under which the compaction by the upper level of the soil becomes ineffective, of an underground compacting device. By advancing this device, the soil (104) can be compacted below this specified depth. Thanks to this invention it is possible to compact thicker layers and to improve the railway tracks repairing systems.
