FIELD: building, particularly underground or underwater structures.

SUBSTANCE: method involves building foundation; heating thereof before pouring concrete mix and performing concreting cast-in-place blocks by pouring concrete mix having different temperature along structure height; vibrating concrete mix; covering structure surfaces not enclosed by form with water-impermeable and heat-insulating material and curing thereof in form up to obtaining necessary concrete strength. Foundation is formed of piles arranged along tunnel wall axes. Foundation is heated up to 5 - 20oC. Concreting of members supported by wall piles is performed by filling form with concrete mix under temperature of 20 - 30oC up to level located at height exceeding height of wall component with 4 m-1 surface modulus by 500 mm. Remaining wall and floor structure parts are filled with reinforced concrete mix under 10 - 20oC temperature. Concrete of outer pile foundation area having 600 - 800 mm height measured from contact line with concrete mix is heated up to obtaining 0.28 - 0.3 R28 concrete strength. Form material and covering material have thermal resistance of 0.2 - 0.3 (m2·deg)/W. Form for forming wall components having 4 m-1 surface modulus are coated starting from bottom by material having thermal resistance of 0.2 - 0.5 (m2·deg)/W to improve warmth-keeping thereof. Height of form to be covered and concreting block height are determined from given formulae.

FIELD: building, namely underground structure erection, particularly for building multipurpose pipelines under acting roads without traffic interruption and in difficult mining and geological conditions and in presence of watered tunnel base ground.

SUBSTANCE: method involves forming minitunnel by successive driving hollow reinforced concrete sections in ground and/or embankment along with simultaneous supplying thixotropic mix; connecting above sections one to another and to neighboring pipeline sections during driving thereof. Pipeline sections have opened end parts. One end part has annular grove opened from section end for receiving metal shell extending out of the section end and having thickness of not more than groove depth. Shell and end section part form stepped funnel. The second section end part tapers in stepwise manner to end thereof to form bush part having one step for shell of neighboring section receiving. The second section end part is provided at least with one step for gasket. Gasket is made of pliable sealing gas-and waterproof material and bearing against step surface by one gasket side and against inner shell surface by another side thereof. Steps of bush part are formed within half of thickness of section wall facing outwards, wherein neighboring sections are located so that gaps are formed between ends thereof. Compression ring and additional gasket abutting compression ring are installed in above gap. Additional gasket is made of pliable gas- and waterproof material and bears against inner shell surface by outer ring side and to neighboring section ends by end surface thereof.
