BASE FOR LINEAR GROUP OF RESERVOIRS Russian patent published in 2013 - IPC E02D27/38 

FIELD: construction.

SUBSTANCE: base for a linear group of closely located reservoirs comprises a pit, a gravel-sand or a crushed stone cushion with layerwise compaction. The gravel-sand cushion is made in the form of a solid strip under a group of closely located reservoirs, in amount of at least two and has width equal to (0.3-0.8)D, and length for extreme reservoirs equal to (0.5-0.9)D, where D - reservoir diametre. Side slopes of the pit are made with an inclination α=15°-70°, where α - angle of inclination of a side face of the pit relative to the horizon.

EFFECT: increased service life, higher operational reliability of reservoirs due to levelling of difference in subsidence of walls and bottoms of reservoirs.
