FIELD: environment protection, particularly to recover and clean relatively small lakes of plant deposits. ^ SUBSTANCE: method involves emptying lake; diverting inflowing water; drying accumulated plants and bed silt by cutting drain trenches; cutting accumulated plants and bed silt by means of earth-shifting machine bucket. First of all road for earth-moving machine is built along water pool perimeter. Drying trench with pump arrangement accumulation zones is dug along water pool edge so that unexcavated zone, namely bridge, is left. Dug-out plants and bed silt are laid on road ground to create flat pile. Remainder water is removed from water pool and accumulated plants and bed silt are naturally dried. After that drain trenches are cut by means of earth-shifting machines moving over the bridge and natural drying is repeated. Dried plants and silt are burned in-situ. ^ EFFECT: increased efficiency and economy of lake cleaning. ^ 4 dwg |
