METHOD FOR CONSTRUCTION OF DAM MADE OF EARTH MATERIALS IN WATER RESERVOIR

摘要

Method for construction of dam mage of earth materials in water reservoir includes pouring earth of body of dam to water with installation in central zone of dam of antifiltering element. To increase impermeability to water of antifiltering element of dam first in central zone of dam in contour of the upper and the lower faces of antifiltering element upper than level of water of water reservoir one tightens two cables. The cables are fixed on anchor supports and rest within boundaries of water reservoir on floating pontoons anchored with cables with loads to bottom of water reservoir. After that with advance, before landfilling to each of those cables one attaches sheets of water-impermeable film with closing seams between sheets, those by means of loads are fixed to the bottom of water reservoir, with formation of sheets of film of the upstream and the downstream screens of antifiltering element. Landfilling is performed simultaneously in parallel to side sections of dam and to inner cavity of antifiltering element formed with the upstream and the downstream screens.
