Scientists from the South Ural State University (SUSU) in Chelyabinsk have developed and patented a technology that significantly strengthens dams, weirs, and other hydraulic structures. The new method compacts the soil to a depth of more than three meters, which is several times greater than the capabilities of existing vibratory rollers that only affect the top layer up to 1.2 meters.
The method compacts the soil to a depth of 3 m or more, while the soil density is the same throughout the cross-sectional height. The technology also allows creating a framework inside the compacted soil mass. Scientists claim that there are no similar solutions in Russia or in the world today.
The patented mechanism is attached to the excavator boom and, when immersed in the ground, rotates to wedge and compact it in all directions. Concrete is then poured or crushed stone is backfilled into the resulting funnel, forming a strong framework. This technology improves the stability of hydraulic structures and extends their service life.
