Electro-impulse Device for Installation of Bored-Injection Piles

The developed electric pulse device (EPU) has the uniqueness and novelty in the technical solution for the use when installing bored-injection piles (piles-ERT). The EPU device makes it possible to produce piles-ERT with increased bearing capacity. Due to the presence of a high-energy capacitive accumulator with a switch that is connected to the discharger of the radiator of accumulated energy, the EPU is an original electro-technical structure. It is a unique high-performance aggregate for the installation of piles of increased bearing capacity, as well as for cementation of bases. The device has no analogues abroad. It is found wide application in geotechnical construction when erecting piles-ERT in pile fields, fencing of pits, cementation of bases, etc.
