FIELD: hydraulic engineering.
SUBSTANCE: invention can be used as bank strengthening structures in river and canal courses. Proposed fastening contains gauze metal cylinders with filled-up inner space connected to form solid fastening. Gauze cylinders of parabolic form are made by winding gauze over bush of tree branches laid on prepared base of slope and are secured on slope by anchors over line of contact of gauze and base. Lower part of fastening is dipped to depth exceeding depth of expected degradation. Parabolic cylinders can have crosswise or longitudinal orientation relative to direction of stream. Said parabolic cylinders can be made of woven gauze or rigid gauze with double twisting of wire between meshes.
EFFECT: improved efficiency of protection of banks, increased service life of construction, reduced construction and service expenses.
