SYSTEM OF MOBILE DAMS AND METHOD FOR ITS ERECTION Russian patent published in 2015 - IPC E02B7/00 E02B3/10 

FIELD: construction.

SUBSTANCE: system includes one or more sections 1 consisting of two internal water-filled envelopes 2, external protective envelope 3, which are tight on two lateral sides. The system includes diaphragms 10 and anchors 9 at the bottom of the sections and a water drain of nappe-shaped profile 5 with flexible outlet tray 7. A parabolic shape of tray 7 is supported with longitudinal water-filled envelopes 8. Sections 1 are connected to each other by means of flexible braces 4. An erection method of the system of mobile protective dams involves selection of a route, a layout and filling of section 1. Two internal water-filled envelopes 2 are filled by means of envelope filling device 6. Then, external protective envelope 3 is filled. Anchors 9 come forward under action of pressure inside the external protective envelope by means of diaphragm 10. Then, by means of flexible brace 4 there installed to the end face of section 1 in the route direction is the next section 1 of the water drain of nappe-shaped profile 5, and flexible outlet tray 7 with longitudinal water-filled envelopes 8 is attached. After that, depending on distance of the protected territory, one or more sections 1 are attached.

EFFECT: safety at rise of the level in natural or artificial water courses, at breakthrough of hydraulic structures, discharge of excess water course to natural wells, thus not subjecting populated localities to flooding.
