METHOD TO ERECT UNDERGROUND STRUCTURES BY "WALL IN SOIL" METHOD AND WALL IN SOIL ERECTED BY THIS METHOD Russian patent published in 2012 - IPC E02D5/20 

FIELD: construction.

SUBSTANCE: invention may be used to erect prefabricated reinforced concrete underground structures by "wall in soil" method, in particular, pit barriers, underground floors of buildings, tunnels and headers of various purpose, crossings. The method to erect underground structures by "wall in soil" method includes working of a trench under protection of a drilling mud within one bay, submersion of a reinforced concrete panel into the trench, with subsequent serial working of the trench and submersion of panels into it at adjacent bays, and joint grouting of seams between panels and the gap between the panel and the pit wall is carried out. The reinforced concrete panel "wall in soil" for each bay is assembled prior to its submersion and/or in process of its submersion into the trench by connection of prestressed reinforced concrete elements with the size of not more than 24×1.5 m and thickness of 0.2-0.5 m along width, and/or thickness, and/or height of a "wall" with the help of a pile driver tilting gear with a platform.

EFFECT: reduced material intensity and weight of a structure, simplified assembling works and transportation.
