METHOD TO PREVENT COLLAPSE OF STEEP RIVER BANKS Russian patent published in 2020 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering and nature protection construction and can be used for protection of coastal zones from landslides and caving of soil massifs. Purpose of the invention is to increase productivity of works on hydraulic washing of soils that form a steep shore without damage to safety of these works and use of hydraulic transportation of removed soil without damage to its further use when backing up the water-guiding shaft. Soil washing and formation of terraces begins with upper soil layers. For this purpose a dredge is installed on the surface of the shore and two inclined wells are drilled from the shore surface to the river water rim for water supply to soil washing-out and removal of the obtained pulp for back-filling of the water-guiding shaft. To receive pulp, flexible containers of water-permeable geomaterial are used.

EFFECT: disclosed method makes it possible to use not only hydraulic but also mechanical action at soil washing, without damage to safety of works, and also to use the obtained pulp for formation of water-guiding shaft.
