Hydraulic filling for closing the channel of the volga at the side of the cheboksary hydroelectric station
Conclusions 1. The use of hydraulic filling for closing the channel of the Volga at the site of the Cheboksary hydrostation showed that high productivity and efficient operation of suction dredges under severe weather conditions is possible with thorough performance of preparatory works on stockpiling soil and clearing construction trash from sections of cofferdams to be excavated. 2. When closing river channels it is necessary to accomplish, as far as possible, maximum narrowing of the channel by hydraulic filling into the flow by dredges, which makes it possible to reduce the use of costly imported materials and to reduce the volume of hydraulicking works before the start of the final stage of closing the channel. 3. In the presence of a shuga run, the construction of a channel earth dam should be carried out with negligible lagging of the narrowing of the channel by hydraulic fill over the entire width behind the narrowing of the gap by a berm, with consideration of the volume of works, time of their performance, and selection of the appropriate means of mechanization.
