APPARATUS FOR MONOLITHIC LINING OF CHANNEL Russian patent published in 2016 - IPC E02B5/02 

FIELD: construction.

SUBSTANCE: invention relates to hydrotechnical structures and can be used in construction of channels and their reconstruction. Apparatus for performing a monolithic lining channel includes a fixing chute with pulley, drive mechanism and solution-distributor device, a flexible framework in the form of toroidal cylinder with inner walls are spiral twisted with each other relative to its longitudinal axis, mounted in a fixing chute, and drive closed flexible link, reeved in pulley fixing chute and passing through the middle of formwork. In the cavity forms an insert of a rigid light material in the form of toroidal cylinder with central bore axis with diameter exceeding total diameter of inner walls of formwork and flexible link. Whole surface of the insert is coated with antifriction lubricant.

EFFECT: use of the offered device allows not lose its serviceability at punctured or damages of shell formwork, since hard insert is not able to escape from the cavity forms, and this contributes to a significant improvement of reliability.
