DEVICE FOR STRENGTHENING EARTH HEAVY RELIEFS Russian patent published in 2018 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: invention relates to the field of transport and hydraulic engineering construction and can be used to protect against wind waves and to prevent erosion of shores of lakes, rivers, reservoirs, slopes of soil dams, canals, railway and road embankments of the roadbed. Device for strengthening the slopes of the roadbed includes a flexible, non-removable formwork, consisting of sewn together upper and lower water-permeable sheets of geotextile material and forming sequentially located cavities – cushions, filled with concrete and having internal vertical connections, the underlying layer of the filter cloth and filter elements. Pillows are made hydraulically isolated from each other, are equipped with individual nozzles with a non-return valve for supplying concrete and discharges from water-permeable webs of geotextile material, are interconnected by flexible bridges, made with the help of editions of water-permeable sheets of geotextile material. Flexible bridges are located along the perimeter of the pillows and serve as filter elements.

EFFECT: technical result consists in ensuring the production of inexpensive in the manufacture of and easy to install flexible slope cover, which has sufficient reliability in operation due to its high filtering ability, ensuring a good adaptation to the change in the relief of the surface of slopes and the bottom of the watercourse during washouts while using and preventing further erosion processes.
