METHOD OF FLOOD PROTECTION Russian patent published in 2015 - IPC E02B3/00 E02B3/10 

FIELD: construction.

SUBSTANCE: method includes erection of coast-protecting structures on lowered sections and sections subject to flooding on backwater soil structures in the form of a prefabricated discharge structure 1 opposite to a superfluent flow with fixation of water impermeable protective means at the side of an inclined discharge part and with the possibility of dismantling upon the end of flood. The prefabricated discharge structure 1 is made of modular type with support units and with the inclined discharge face. Modules are assembled in the form of rod tetrahedrons of quick-split design according to the scheme of a three-hinged arc or the scheme of a welded or a disassembled arc. Modules are installed at the distance from each other or nearby with account of features of the relief and contour shape of the discharge structure, and they are fixed either in soil with the help of support elements, or on a foundation laid onto a hydraulic insulation layer. In the modules a massif 5 is installed, providing for resistance against hydrostatic pressure, and modules are connected to each other with the help of shields 7 and/or rods, which are fixed in units of modules with the help of connection elements. At the discharge side they install hydraulic insulation protective means that form a water impermeable protection in the discharge zone with a stiff and/or flexible structure of a discharge face.

EFFECT: increased efficiency of the method of flood protection by means of provision of safe flood flows via soil structures with provision of integrity of a flood protection structure, labour inputs during its erection are reduced, and possibility is provided to use it on the area with complex relief.
