FIELD: hydraulic and irrigation building, particularly to protect banks of rivers, channels, dam slopes and other structures against erosion. ^ SUBSTANCE: bank-protection structure consists of shafts fixed in gabions from lower ends thereof. The gabions comprise nets filled with stones and have cylindrical shapes built below eroded zone level. The shafts are vertically installed in the foundations in one or several rows. The shafts are spaced apart and installed in direction parallel to river flow. The shafts are trees or reinforced concrete posts fixed inside the gabion by stones. The cylindrical gabions are connected to net laid along river flow in horizontal plane. Space between vertical shafts and bank may be filler with trees or bushes. Cylindrical gabion tops may be covered with concrete. ^ EFFECT: increased efficiency of bank protection and extended service life of bank-protection structure. ^ 6 cl, 5 dwg |
