STORAGE TANK CONSTRUCTION

摘要

This invention relates to an elevated liquid storage tank and a method of constructing same. An upright, hollow, cylindrical concrete shaft is constructed having a closed upper end portion forming a tank support floor. An upper, outer ledge is formed around the periphery of the shaft adjacent to the tank support floor; and a central, upright access tube is mounted in the tank support floor. An annular, steel tank wall is fabricated around the base of the shaft and hoisted to the top of the shaft using a plurality of jacks. The tank wall includes a lower annular ring beam and the space between the ring beam and the shaft upper end portion is filled with reinforced concrete to connect and retain the tank in position. Roof plates extend between the access tube and the tank wall to close the storage tank roof.
