FIELD: construction of underground structures of civic, transport and agricultural applications. SUBSTANCE: the offered structure has walls, vault and trough. Vault is made in form of a part of ball shell and wells from pairs of internal and external piles combined by circular foundation mat with through apertures between separate pairs for radial adjoining of underground tunnels. External piles are inclined, and internal piles are vertical and combined by circular connector whose upper end face adjoins the foot of circular foundation mat, and lower end face adjoins the through. The method of construction of structure includes erection of walls. For which purpose, first, circular trench is excavated over the perimeter of vault heel down to foot elevation of circular foundation mat. Then, vertical and inclined piles are hammer-driven into bottom of trench, reinforcement is installed by pile heads and circular foundation mat is corrected in trench. Then, vault is erected using forms from ground with subsequent reinforcing and concreting of vault by forms shape. Ground between walls is removed through apertures between piles, and prior to making trough, circular connector is erected to combined vertical piles between one another. EFFECT: higher efficiency. 2 cl, 4 dwg
