Specification for construction and acceptance of steel storage tank subgrade & foundation in petrochemical industry
1 Scope
This specification specifies the technical and quality criteria as well as project acceptance and technical documents for completion for the construction of steel storage tank subgrade & foundation and foundation settlement observation.
This specification is applicable to the construction and acceptance of vertical cylindrical steel storage tank subgrade & foundation in petrochemical industry and coal-chemical industry and the construction and acceptance of the steel gas tank subgrade & foundation, but not applicable to the construction and acceptance of the prestressed concrete steel storage tank subgrade & foundation.
