在122.9 m高的超高层等比例试验塔上,采用定流量法,对比研究了在不设置、隔层设置和每层设置吸气阀的条件下,特殊单立管排水系统的排水能力和压力变化规律。结果发现,设置吸气阀能够同时缓解特殊单立管系统内的正、负压,且每层设置吸气阀时的缓解效果优于隔层设置。
On the 122.9 m high-rise equal-proportion test tower, the constant flow method was used to compare the drainage capacity and pressure of the special single-riser drainage system under the condition of no setting, compartment setting and suction valve on each floor. The law of change. The results showed that the setting of suction valve can relieve positive and negative pressure in the special single-tube system at the same time, and the mitigation effect of each valve is better than that of the compartment.
