METHOD FOR DEEP VIBRATION COMPACTING OF SANDY GROUND

FIELD: construction engineering. SUBSTANCE: according to method, sunken into sandy ground is vibrating compactor. Sinking depth is dictated by design requirements. Operating compactor is kept in ground as required and then is lifted to ground surface. In its lower part, compactor has three-dimensional structure which is made up of radial components. Compactor together with three-dimensional structure is used in ground section with height h from 1.5-2 m to 1/2 of designed depth of ground to be compacted. This relates to each layer of ground being compacted and subjected to compacting action produced by three-dimensional structure of compactor. Duration of compacting action depends on initial density of ground in given layer so as to ensure more or less uniform density of ground in depth. EFFECT: higher efficiency. 2 cl, 4 dwg
