Abstract: The article analyzes the most effective domestic and foreign modern methods of micropiles, including those using electric discharge geotechnical technology (ERGT), and tubular piles made of high-strength cast iron with spherical graphite (HCG). The trend of development of microswire device methods is shown.

Keywords: drilling-injection piles, pile construction technology, microswitches, electric discharge geotechnical technology, discharge pulse technology of RET, pile pipes made of high-strength cast iron with spherical graphite (HCG).
