This specification specifies the construction quality standard and inspection and test requirements for equipment concrete foundations (hereinafter referred to as equipment foundation) in petrochemical industry such as excavation and filling of foundation trench, formwork and support, reinforcement and concrete, pre-embedded facilities and grouting.
This specification is applicable to the acceptance for construction quality of cast-in-place concrete foundations such as equipment, framework and pipe support in newly-built, extended and renovated projects in petrochemical industry but not applicable to the acceptance of foundation construction quality of prestressed concrete structures.
