Conclusions
-
1.
The SVD-500R units, SO drilling rigs, and other Soviet-made equipment for constructing walls in the ground were mastered and improved during construction of the cutoff curtain at the Kiev pumped-storage plant.
-
2.
The method of constructing clay curtains by filling the trench with ball clay under bentonite clay is a method that is progressive, economical, simple, and reliable with respect to cutoff characteristics.
-
3.
The construction of concrete curtains is the most expensive and labor-consuming measure. It is better to use such curtains when constructing bearing walls.
-
4.
The results of year-long observations showed that the curtain is serving its purpose-it is preserving the hydrogeologic conditions that existed before filling the reservoir.
