在超高层足尺试验塔上,研究内螺旋管单立管排水系统的横干管对模拟污物的输送能力。试验结果表明,管径为DN100的排水横干管对模拟污物的输送能力受管道坡度的影响较大,在相似坡度下,管径为DN150的排水横干管对模拟污物的输送能力较好,并且系统1层横支管内压力受到的影响较小。

In a super high-level full-scale experiment tower, capacity of horizontal trunk pipe of a single stack drainage system with inner spiral pipe to transport simulated sewage was studied. The results showed that the transport capacity of simulated sewage by the DN100 horizontal trunk pipe was greatly affected by the pipe slope. Under the similar slopes, the DN150 horizontal trunk pipe had a better transport capacity for simulated sewage, and pressure of the horizontal branch pipe at the first floor of the system was less affected.
