FIELD: building, particularly for compacting frozen sandy or ground filler.
SUBSTANCE: method involves vibratory deepening compaction device in sandy filler layer along with vibrating thereof; lifting compaction device; periodically repeated deepening compaction device for a given length simultaneously with continuous vibrator operation. Sandy filler is defrosting before compaction device deepening and then drainage means is installed in filler layer. Drainage means are located at depth equal to 1/8-1/2 of filler layer thickness. Draining means are formed as horizontal perforated tubes covered with filtering material. Vibratory deepening of compaction device is carried out through the whole filler thickness, namely through 0.7 - 10 meters. Vibration of filler layer is performed within 2-7 minutes. Compaction device is lifted in several steps, each step includes lifting compaction device for 20-40 sm height, vibrating compaction device within 2-3 min and vibrating the next filler layer. After full removal of compaction device it is repeatedly lowered into filler layer at distance of 20-150 sm from previous place of deepening thereof with continuous vibrator operation.
EFFECT: increased compaction efficiency, improved uniformity of filler compaction along its height.
