FIELD: construction.SUBSTANCE: screw pile in soil comprises a hollow shaft and soil at its outer side, besides, the shaft is equipped with helical blades, and holes are made in the lower part of the pile shaft, and the soil adjacent to the pile is loose. Holes are arranged under the lower blade evenly along the spiral, the twisting angle of which matches the twisting angle of the lower blade. Soil adjacent to the pile is evenly mixed with soil-strengthening mixture along trajectory of passage of helical blades of the pile during its screwing and is connected with the strengthened layer of soil arranged below the blade.EFFECT: increased reliability of a screw pile in process of its operation, increased bearing capacity and resistance of a pile.1 dwg |
