FIELD: hydraulic engineering, industrial and civil water-resources and land development. ^ SUBSTANCE: device comprises buried cantilever retaining wall arranged along outer boundary of territory to be protected at design depth below normal water level. Device also has deep-laid gravity drain system located from the side of territory to be protected in parallel to cantilever retaining wall. Retaining wall top is on maximal water level determined with taking into consideration wave height. Gravity drain system comprises deep-laid fissure drainage and vertical drain wells. Each drain well is connected to corresponding well, which diverts drain water. Gravity drain system may be also formed as deep-laid fissure drainage and perforated vertical inverted drain wells. ^ EFFECT: reduced ground water level and hydrostatic pressure acting to cantilever retaining wall from the side of territory to be protected, provision of drain flow removal, improved ecological conditions and increased seismic stability of shore protection devices. ^ 6 dwg |
