METHOD OF ERECTION OF UNDERGROUND STRUCTURES ALONG RIVER BED OR CANAL Russian patent published in 2019 - IPC E02D29/77 

FIELD: construction.

SUBSTANCE: invention relates to construction structures and can be used in construction of motor roads, railway tunnels, underground buildings and structures under water channels or rivers along their bed. Method of erection of underground structures along river or canal channel includes temporary closure of water flow of river or channel by means of dam, with start of water flow along other available or temporarily created bypass route, further excavation of dried canal and arrangement of foundation. Buildings with walls are erected on the foundation. Above the walls the slab is erected, which is the base under the channel of the river or canal flow, then the water flow is again started. Dams at the beginning and at the end cover the whole water flow of part of the river or channel in the zone of presence of bypass route for flow of water flow, or create an artificial time route for flow of water flow. Said overlapped section is drained. After that, bottom is excavated and construction is carried out along river bed or canal. First trench is excavated and walls are walled, and floors are installed above walls.

EFFECT: technical result consists in enabling construction of roads, railway tunnels, underground buildings and structures under and along the channel of water channels or rivers, providing a fast and technically simpler method of construction, wherein it is also possible to change channel or river bed depth with simultaneous cleaning.
