DEVICE TO PREVENT FRESHETS Russian patent published in 2004 - IPC

FIELD: hydraulic works.

SUBSTANCE: invention relates to hydraulic structures and methods of prevention freshets and rain floods. Proposed device includes module structures whose upper level is higher than expected level of flood water and made of material capable of considerably increase its volume at wetting. Said module structures are made up of set of several layers of elastic material, three minimum, one of which is placed inside limiting layers and is made perforated. Composite compound is applied from both sides of said inner perforated layer. Set of layers is covered from top with elastic watertight material. Inserts made of water filtering material are provided in each modular structure in lower and side walls made of elastic watertight material. Upper wall of elastic water material can be provided with water filtering inserts protected by temporary film. Set of layers of elastic material can be packed on reel in form of roll.

EFFECT: improved reliability of protection of near territories, mobility of transportation of guard, reduced labor input at mounting.
