METHOD FOR EMBEDDING FILTRATION DEFORMATIONS IN CHANNEL DAM Russian patent published in 2015 - IPC E02B3/12 E02B3/16 E02D17/10 E02D31/02 

FIELD: construction.

SUBSTANCE: invention relates to hydrotechnic and environmental construction and may be used when conducting rescue and recovery operations under water, repair of protective and regulating dams by embedding filtration passages, cracks and holes, as well as shore protection structures in the eroded river beds, canals and other facilities. Gabion mattresses filled with stone are placed along the banks of the canal bed. Cloth of woven geotextile is attached to gabion frame throughout the perimeter by means of wire. Then, the cloth of waterproof polymer geomembrane is attached by means of metal clips. In this case, the protective waterproof coating is made with margin throughout its perimeter. Waterproof geomembrane is made of polyethylene of low or high density, including made of polymeric wastes. Ready gabion structure with protective coating is placed under water on the slope by means of crane, and free filtration passage in the channel dam is sealed in the same way.

EFFECT: improvement of the method.
