FIELD: transport.SUBSTANCE: invention relates to making underground reservoirs in rock salt formations. Reservoir is profiled using concentrically arranged tubes to lift brine, feed water and production pipes. Thereafter, water feed pipe is withdrawn to feed water feed column composed of flexible water feed pipe. Then, reservoir shape is corrected by feeding solvent at reservoir correction point via gap between brine lift tube and flexible water feed pipe of said column. Additionally, device comprises water feed column with flexible water feed pipe ropes arranged in symmetry about is cross-section and passed through rings rigidly secured to flexible pipe at regular spacing to connect flexible pipe bottom end with auxiliary winches.EFFECT: expanded operating performances.2 cl, 2 dwg |
