The paper theoretically substantiates and experimentally verifies the design of a combined double-acting anchor combining a pile part (compression work) and a wire with a conical tip (pulling work). It has been found that the bearing capacity of a wire anchor exceeds that of a pile by 20-25 times due to the involvement of the soil cone in the work. The influence of geometric parameters on the pulling force was determined by the method of a complete factor experiment. A support and anchor foundation with an insulating shell has been developed to ensure operation under variable loads. Technical solutions are protected by patents of the Russian Federation.
