FIELD: construction.
SUBSTANCE: drillstrings are arranged with appropriately directed devices, then surface erection and submersion of the entire massif of the facility is carried out in tiers along drillstrings as along guides. The first tier of the facility comprises a technical floor and one or more above floors, and subsequent tiers consist of one or more floors. Submersion of the facility is carried out as soil is excavated in the technical floor together with barrier walls, crossbars, slabs, and extraction of soil, supply of materials and equipment is carried out via technological openings in facility slabs.
EFFECT: reduced labour intensiveness and material intensity, reduction of time for erection of an underground facility, provides for higher stability of a facility during submersion and higher accuracy of facility submersion.
