FIELD: construction; foundations on piles.
SUBSTANCE: structure of the ground prefabricated foundation of a high-speed rail transport overpass consists of a reinforced concrete base slab and piles. The reinforced concrete base slab consists of slabs, the side surface of which contains protrusions for connecting the slabs to each other; the base slab contains anchorage for the overpass supports, vertical and inclined holes for piles. Piles installed vertically in the ground are screw piles; in the upper above-ground part they have a nut, a thread and a support ledge for a reinforced concrete base slab; the upper part of all screw piles ends with a multifaceted prism.
EFFECT: increasing the stability of a prefabricated ground foundation to loads from the movement of high-speed rail transport in a wide range of soil strength.
