Increasing the bearing capacity of the base is an actual problem in geotechnical construction. With increased loads on the base, the use of traditional technologies is not always justified. It is necessary to use non-traditional ways to strengthen the bases. Most often, the situation is aggravated with the presence of weak underlying layers with unstable physical and mechanical characteristics in engineering-geological sections. When such bases are strengthened with traditional piles, they can get negative friction, which reduces their bearing capacity in relation to the ground. This article presents the developed algorithm for the installment of combined soil-concrete bored piles with simultaneous fixing of weak engineering-geological elements. At the same time, in areas with weak layers along the length of the piles, the developed geotechnical technology makes it possible to arrange the widenings obtained from the joint use of get-technology for the installment of soil-cement piles and electric-discharge technology for bored-injection piles EDT. The final result of the new technology is a soil-concrete pile with multi-seat broadenings, which has increased values of bearing capacity in relation to the ground.
