1.引言随着建筑技术的不断发展,大屋面、大跨度、结构复杂的大型建筑不断涌现,例如厂房、机场、体育馆、展览馆、高层裙房等,要求降雨时屋面积蓄的雨水在短时间内能够迅速排出,传统的重力式雨水排水技术已经不能满足这类建筑物的排水要求。虹吸式雨水排水系统是国际上较为先进的屋面雨水排放系统,广泛应用于大面积、大跨度、结构复杂的屋面排水,因此采
1. INTRODUCTION With the continuous development of building technology, large-scale roofs, large-span structures and complex structures such as factories, airports, stadiums, exhibition halls and high-rise podiums are emerging. Rainwater storage on the roof is required for a short period of time Within the rapid discharge, the traditional gravity drainage technology has been unable to meet the drainage requirements of such buildings. Siphonic rainwater drainage system is more advanced in the world of roof drainage system, widely used in large area, large-span, complex structure of the roof drainage, mining
