Foreword
This specification is based on the four food engineering construction standards issued by the State Food Bureau Office on the establishment of the “Guidelines for the Construction of the Grain Depot Management Information System”.
The notification of the task (Guoliang Office Exhibition [2005] No. 186) was requested by the National Grain Reserve Bureau of Zhengzhou Scientific Research and Design Institute.
The construction unit constitutes a revised compilation group, and the industry standard of the Ministry of Internal Trade of the People's Republic of China, "Code for Design of Grain Cylinders" (Trial)
SBJ10-97 was fully revised.
This specification is divided into eight chapters and six appendices. The main contents are. the design principles of the construction, structure, technology and electrical of the grain silo.
method. The revised content mainly involves. the arrangement of the original specification chapter, the use function of the grain storage silo, the inspection requirements of the crack detection of the silo wall, and the horizontal pressure
The force correction factor and other contents have been appropriately adjusted.
During the revision process, the preparation team conducted extensive and in-depth investigations and carefully summarized the improvement in the use of World Bank loans since.1997.
The experience of the national grain circulation project and the construction of 50 billion kilograms of national grain storage, reference to the US "Code for Design of Reinforced Concrete Silos"
ACI313.97 and related standards of other countries, carried out a lot of calculations and arguments, and repeatedly asked for relevant designs in the domestic grain industry.
The opinions of the units and experts were finally finalized after review.
In this specification, the provisions of the boldface logo are. 3.1.5, 3.1.6, 3.2.1, 4.1.10, 4.5.18, 4.5.19, 4.5. 20, 4.5.21,
4.5.23, 4.5.24, 4.5.25, 5.5.5, 6.1.1(1), 6.1.9, 6.6.3, 6.9.1 (1), 7.3.3, 7.6.3, 8.1.5 are mandatory provisions,
Must be strictly enforced. The original industry standard "Code for Design of Grain Cylinders" (SBJ10-97) was abolished at the same time.
This specification is administered by the State Grain Administration. In order to improve the quality of the standard, all units are required to combine the engineering practice in the process of implementing this code.
