METHOD OF GROOVE IMMERSION WITH PENETRATION IN DENSE WATER-PROOF SOIL Russian patent published in 2014 - IPC E02D7/18 

FIELD: construction.

SUBSTANCE: according to a groove immersion method with the penetration in the dense water-proof soil by means of vibrotechnical tools, the groove immersion is carried out successively in a two-stage mode: within the upper column of weak soils the groove is immersed in the mode of harmonic oscillations with a frequency of 1000-2500 oscillations per minute and an amplitude of 10-20 mm, and at the achievement of a layer of dense water-proof soil by the groove, the operation mode of the vibrotechnical tool is changed to a low-frequency impact mode with a frequency of at least 420 oscillations per minute at a jump height of a shock weight of 20-40 mm and a ratio of this weight of the vibrotechnical tool to its driving force equal to 0.4 is maintained.

EFFECT: provision of stability and water resistance of ditch sheetings for various purposes.
