摘要
通风系统是保障地下厂房洞室群施工顺利进行的重要一环。针对安徽金寨抽水蓄能电站交通洞施工现场实际情况,设计有毒有害气体监测系统,进行气体粉尘及CO有毒气体浓度的监测,并结合数值模拟方法分析其运移规律,利用实测数据验证了模型的准确性。同时通过改变通风机布置方案,能有效减少爆破后排烟及施工等待时间,同时节约施工及风管布置成本。研究结果可为地下厂房洞室群施工通风设计提供参考。
Ventilation system plays an important role in the construction of underground power house.Aiming at the situation of construction in the traffic tunnel of Jinzhai pumped storage power station in Anhui Province,a monitoring system of poisonous gas was designed to monitor the concentration of dust and CO gas.Meanwhile,the migration regularity was analyzed by numerical simulation.The accuracy of the model was verified through the measured data.Then changing the arrangement of ventilators ,which can effectively reduce the smoke exhausting and construction waiting time after blasting,meanwhile save the cost of construction and ventilator duct arrangement.The research can help for the design of ventilation system during the construction of underground power houses.
