AI Technical Summary

Technical Problem

During use of the vault storage tank, materials are prone to accumulate in the ribs on the tank roof dead zone, resulting in material pollution and safety issues. The tank roof construction is difficult and the preparation cost is high.

Method used

A storage tank top structure is designed, including a spherical shell, radial beam, annular beam, annular plate and a central ring. The annular foundation structure is formed through sealing welding, reducing the difficulty of high-altitude construction, and connecting it with the tank wall through the annular plate to enhance the stability and strength of the structure.

Benefits of technology

The safety, stability and high strength of the tank top are achieved, the construction difficulty and preparation cost are reduced, and the material accumulation and pollution problems are avoided.

Abstract

A foundation structure in a tank top comprises a spherical shell and a plurality of radial beams arranged on the protruding side of the spherical shell, the spherical shell comprises a plurality of tank top plates which are sequentially welded in a sealed mode in the circumferential direction, and the radial beams are welded to the tank top plates in a one-to-one correspondence mode. The foundation structure does not need to be completed above the tank wall, and the construction difficulty is reduced. The tank top further comprises a plurality of annular beams distributed in the circumferential direction of the spherical shell, and the two ends of each annular beam are welded to the two corresponding adjacent radial beams correspondingly. The two axial ends of the annular plate are welded to the sunken side of the tank wall and the sunken side of the spherical shell in a sealed mode respectively, the annular plate is located between the spherical shell and the tank wall, the annular plate can be welded to one end of the tank wall firstly, then the foundation structure prefabricated into a whole is hoisted and then connected to the annular plate, and the construction difficulty is reduced; the strength is guaranteed, the storage tank structure and the preparation process are simple, the construction difficulty and the preparation cost are low, and the technical problems that the storage tank top is large in construction difficulty and high in preparation cost are solved to a certain extent.
