DEFORMATION-INSULATING SUTURE Russian patent published in 2020 - IPC E02B3/16 

FIELD: building; hydraulic engineering.

SUBSTANCE: invention relates to hydrotechnical construction, namely to expansion joints of protective coatings of canals and water bodies, as well as it is used in creation of underground reservoirs volumes, for storage of wastes of different production facilities, when seam may be located vertically as well. Deformation-insulating seam includes an anti-filtration element formed from film material, concreting plates immersed into concrete, and a cassette for formation of deformation folds for board connection. According to the invention, an element is used consisting of halves of a pipe, which are installed with the possibility of formation at the point of their joint of through slots, outside of which along the entire length there are rubber bundles, and the cassette is made in the form of a rotary cylinder mounted on the central longitudinal axis of the docked plates for winding film material, which is made of a continuous web pre-folded in half along, then in half across and equal in height to the height of the through slots. Free ends of the web are oppositely withdrawn from the through slots and, after the grips of the rubber bundles, are introduced back through the through slots into the inner space of the element and are embedded into the concrete on the side of the plates to be joined.

EFFECT: increased reliability of deformation-insulating joint operation and simplified technology of its creation.
