FIELD: construction.
SUBSTANCE: method of construction of reinforced concrete deck intersection with large span includes assembly of prestressed unitised units containing channels, through which reinforcing cables are stretched and then tensioned and channels are injected. Seals are installed on the joined surfaces of prestressed unitised units, reinforcing cables are stretched into the channels of upper and lower shelves of prestressed unitised units, prestressed unitised units are tensioned in two horizontal planes by means of tension of cables, and interunit joints are injected by cement mortar in conjunction with channels.
EFFECT: simplification and reduction of construction time of deck intersection, reduction of labour intensity of installation works, increase of bearing capacity of reinforced concrete vessel deck.
