AbstractAbout the AuthorReferences
The impulse-discharge technology of installation of bored-injection piles opens a new direction in geotechnical construction. Due to its specific qualities, it is an original technology. Unlike other technologies, it makes it possible to install bored-injection piles with an increased bearing capacity. The originality of this technology is the use of pulse current generators to create an electro-hydraulic effect in a borehole drilled and filled with fine-grained concrete. The technology of bored piles with the help of a pulse generator improves reliability and electrical safety by reducing the operating voltage. While forming a high-energy pulse, conditions are created under which a shock wave is formed and developed in the form of an electrohydraulic effect in a medium of fine-grained concrete on the ground of the walls of a borehole. The generator of pulse current and high-voltage discharger are a uniform construction. At the same time, PCG is an electric energy storage device, and the discharger discharges this energy in the form of an electrohydraulic effect. This creates a pile-ERT with increased values of the bearing capacity on the ground. PCG is widely used in geotechnical practice for new construction and reconstruction. Being a unique tool for the installation of piles-ERT and cementation of bases, the generator of impulse currents has a wide practical significance in construction.
