Pulse-Current Generator for Drilling-Injection EDT Pile

Nikolay Sergeevich Sokolov*

The developed Electro-Impulse Unit (EIU) has a unique and novelty in the technical solution for use in the arrangement of drilling-injection piles (EDT piles). The EIU unit makes it possible to manufacture high-capacity EDT piles. Due to the presence of a high-energy storage tank with a switch connected to the EIU accumulated energy emitter discharge, it is an original electrical design. It is a unique high-performance unit for high-capacity piles as well as base cementing. The device, having no analogs abroad, found wide use in geotechnical construction for erecting EDT piles in pile fields, fencing of foundation beds, cementing of bases, etc. Ensuring reliable operation of the underground part of buildings and structures erected under complex geotechnical conditions is a very urgent task of modern geotechnical construction. In such non-standard construction conditions, the most acceptable buried structures are drilling piles constructed using the currently existing geotechnical technologies.
