摘　　要：2019年中国北京世界园艺博览会是我国承办的国际级别最高的A1类世界园艺盛会,作为世园会标志性建筑——中国馆,采用建筑覆土的手法,将主要展厅覆盖于梯田之下,在梯田内环中设有埋深9 m、管径2 m的大型地道风系统,该系统利用地表浅层土壤温度变化幅度小、蓄热能力强等特点,能够起到自然换热、防污染、高效利用能源的效果。结合工程特点合理进行管道变形分析,验算确定其材质选用HDPE复合钢带增强螺旋波纹管,严格把控管道连接、加固及回填措施,详细介绍了地道风系统施工中的注意事项,旨在进一步规范地道风施工操作要领。The 2019 China Beijing International Horticultural Exposition is the world’s highest-level A1 world horticultural event hosted by China.As the landmark building of the World Horticultural Exposition - China Pavilion, the main exhibition halls are covered under the terraces by the method of building soil covering.There is a large-scale tunnel wind system with a buried depth of 9 meters and a pipe diameter of 2 meters in the ring of the terraces.The system utilizes the characteristics of small changes in the temperature of the shallow soil on the surface and strong heat storage capacity, which can play a role in natural heat exchange, pollution prevention and efficient utilization of energy.Combined with the engineering characteristics, this paper reasonably analyzes the pipe deformation, checks and determines its material, selects HDPE steel belt reinforced spiral bellows, and the pipeline connection, reinforcement and backfilling measures are strictly controlled. Meanwhile, this paper introduces the precautions in the construction of tunnel air system in detail, aiming to further standardize the essentials of tunnel air construction.
