The paper provides an analysis of floods on the rivers of Yakutia, as well as bank erosion. Electron microscopic studies have established that the nature of the destruction of samples of basalt plastic with a twill weave of reinforcing fibers (3/2) has the form of destruction «ductile-brittle with the pulling out of fibers», which indicates a higher adhesive strength between the matrix and fibers, and the destruction of glass-reinforced plastic samples with plain weave of reinforcing fibers has a fracture pattern “due to matrix shear and delamination”, which indicates adhesive failure. A basalt-plastic sheet piling, obtained by infusion, has been developed, which has a set of operational properties and meets the requirements, the specific indicators of which exceed those of analogues made of steel, fiberglass and PVC.

Various constructive variants of temporary supports of power transmission lines using pultruded fiberglass have been developed and patented. These variants are promising for increasing the reliability and durability of power line supports when used in extreme northern climatic conditions. This paper describes the design features of the proposed technical solutions and their advantages over known analogs. The use of pultruded profiles (such as c-channels, angles, plates, and rectangular pipes) offers an opportunity to develop a wide variety of design solutions. The advantages of the proposed structures are the ease of installation and transportation due to the reduction in the weight of fiberglass parts compared to concrete, steel, or wood, as well as a significant increase in the durability of supports.
