DUAL-TANK LIQUID STORAGE SYSTEM

摘要

A dual-tank liquid storage tank system comprises a lined primary storage tank disposed within a lined secondary tank. Construction of the system involves rolling out a secondary tank liner over an engineered base course, and then laying out a primary tank liner over the secondary tank liner, with an outer portion of the primary tank liner rolled up to fit within the primary tank perimeter. The primary tank's perimeter wall is then assembled from wall panels resting on the secondary tank liner, and then the primary tank liner rolled out and deployed over the primary tank wall. An outer portion of the secondary tank liner is then rolled up toward the primary tank wall, and the secondary tank's perimeter wall is assembled from wall panels resting on the base course. The secondary tank liner is then rolled out and deployed over the secondary tank wall.
