Description

Sliding and positioning method for earthing storage tank Technical Field The invention relates to the technical field of in-place installation of earthing storage tanks, in particular to a sliding in-place method of an earthing storage tank. Background The earthing tank is used as a large storage container, and is also called an earthing bullet tank because of its long cylinder shape. The tank body is generally placed on the supporting surface of the sand bed, the outer surface is completely covered by soil, and only relevant process connecting pipes, manholes, instrument pipe orifices, equipment safety accessories and the like extend out of the soil covering layer. Compared with a ground storage tank or a spherical tank, the method has the advantages that the steam cloud explosion can be effectively avoided, the storage tank is protected from being damaged by adjacent heat sources, explosion shock waves, splashed objects and other factors, the environment is beautified, the project occupied area is effectively reduced, the safety distance between the storage tank and surrounding adjacent facilities is shortened, and the like, and the earthing storage tank serving as a substitute scheme of the spherical tank has good application prospects in the aspects of liquefied hydrocarbon storage and transportation and the like.
