【 摘 要 】

The article sets the objective to develop protective measures when cleaning the bed of the Shershnevsky reservoir of ground deposits using a dredger in the operating conditions of water intaking constructions. As protective measures the authors considered the application of polymer screens made of Dornit geofabric to clean ground deposits using a dredger which allows one not to violate the existing process conditions of the water intaking constructions at the reservoir. The authors developed a structure of a protective polymer screen and the scheme to apply the screen for the conditions of cleaning the bed of the Shershnevsky reservoir of ground deposits using a dredger. The installation of the polymer screens prevents the distribution of turbid suspended solids along the water area of the water body in the course of cleaning. The protective screen to prevent turbid substances in the course of bed cleaning allows blocking the enclosed space from the water surface to the bottom of the water body. It ensures the excavation of ground deposits in a cycle closed from the external water environment with the exclusion of sediment spreading and damage to the water body's ichthyofauna.
