In 21th September, CBMF and CCPA jointly approved and issued the association standards, which are “Technical Specification for Structural Concrete Application of Urban Comprehensive Pipe Gallery"（T/CBMF 91—2020/ T/CCPA 17—2020） and "Large Bending Moment Square Reinforced Concrete Pole" （T/CBMF 92—2020/ T/CCPA 18—2020）,  The standards will be implemented on December 21, 2020.

"Technical Specification for Structural Concrete Application of Urban Comprehensive Pipe Gallery" is applicable to the design, production, construction and quality inspection of new built, expanded and rebuilt urban comprehensive pipe gallery。The issuance and implementation of the standard will standardize structural concrete application technology of urban integrated pipeline gallery, and play an active role in improving the safety and standards of urban engineering pipeline construction and ensuring that the urban integrated pipeline gallery construction is safe, applicable, economical and technologically advanced.

"Large Bending Moment Square Reinforced Concrete Pole" is suitable for the production and inspection of large bending moment square reinforced concrete poles used in power, communication and other projects. The issuance and implementation of this standard will play a positive role in improving the product quality, performance, and promoting the technological progress of the concrete pole industry.
