Concreting the diversion dewatering outlets of the Zeya hydroelectric station
Conclusions 1. The use of poured concrete with plasticizer GKZh-94 in difficultly accessible parts of structures, such as the “plug” of dewatering outlets, is effective with respect to the conditions of delivering the concrete to the placement site and considerably reduces labor expenditures on its compaction. 2. The overconsumption of cement for poured concrete is compensated by the reduction of labor expenditures on delivering the concrete mix to the placement site and its compaction. 3. Under conditions of Siberian rivers with large diversion discharges, it is necessary to have several sets of mechanisms and equipment for closing the outlets — hydraulic hoists, cantilevers, portals, rods, guard gates — for increasing the rate of construction and eliminating downtimes in unforeseen or emergency situations.
