TONGUE-AND-GROOVE WALL AND METHOD OF ITS INSTALLATION Russian patent published in 2024 - IPC E02D5/12 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction in the field of engineering protection of the territory from hazardous geological processes (creeps, landslides, etc.) and hydrotechnical construction of structures using metal sheet pile. Sheet pile wall, completely or partially submerged into soil, contains metal sheet piles with connectors of female and male type for connection of piles to each other into a single sheet pile wall. Lower end of the female-type connector of the pile is equipped with a protective element covering the inner cavity and the slot of the connector, made in the form of a steel plate—a shutter protruding beyond the outer contour of the connector and welded to the lower end on one of its lateral sides.

EFFECT: increased reliability and load capacity of sheet pile wall due to exclusion of soil ingress into internal cavities of pile connectors during submersion and thereby increasing the reliability of the connections of the connectors, as well as reducing the construction time.
