METHOD FOR CONSTRUCTION OF GEOTECHNICAL STRUCTURES IN THE WATER AREA OF URBAN RIVERS AND CANALS Russian patent published in 2023 - IPC E02D29/09 

FIELD: underground structures construction.

SUBSTANCE: invention relates to the construction of underground structures in water areas and in the under-channel space of rivers and canals in large cities. Specifically, to the construction of enclosing and load-bearing walls of underground structures constructed using the technology of trench "walls in the ground", impervious curtains, supporting barrettes, etc. in the waters of urban rivers and canals. The method for erecting an underground structure in the water area includes the development of a trench through the foreshaft and the erection of a protective wall in the ground along the entire perimeter of the pit. Floating pontoons are sunk into the soil at the construction site, the equipment is placed on the decks of sunken pontoons, and the foreshaft is formed from the sides of the submerged pontoons arranged parallel to the gap in the water area, or the foreshaft is formed in the gap between the walls of the embankment and the side of the pontoon, or the foreshaft is formed in the gap between sheet pile wall and pontoon board.

EFFECT: increasing the efficiency of work on the development of the under-channel space of canals in cities without harming the ecology of the space, reducing the labor intensity of work.
