Foundation on screw piles

Screw pile is a steel pillar with a screw blade at the bottom. This blade has an inconspicuous width, which provides the possibility of manual screwing, and also allows you to increase the bearing abilities and strengthen the soil, since the interval gaps are compacted, and not loosened. Initially, such piles were used for supports of bridges and high-voltage lines, but today they are becoming more and more popular in low-rise construction, railway construction, electric grid construction to strengthen soil. To build piles, they are screwed into the ground by at least one and a half meters. If groundwater flows in the upper part, then the pile is increased to a certain depth and screwed until the complete passage of these layers. Screwing is carried out using levers. In simple conditions, two pieces of pipe 2 meters and scrap are required for this. In some cases, special devices are required. 4 people can do work.
