MOVEMENT JOINT (VARIANTS) Russian patent published in 2004 - IPC

FIELD: hydraulic engineering, particularly for antifiltering, may be used in channels and ponds or for creation areas for waster products storage.

SUBSTANCE: movement joint includes concrete or reinforced concrete plates having peripheral bearing areas and film antifiltering material built in plates above bearing areas. Film antifiltering material is connected in holder and ends thereof are overlapped. According to the first embodiment end lap dimension is equal to double bearing area width. In the second embodiment deformation creases are formed of film antifiltering material and maximal crease length is equal to four bearing area widths, creases are overlapped upon bearing areas.

EFFECT: increased joint reliability and simplified technology of joint production.
