智能通风技术在地下洞室施工中的应用

Application of Intelligent Ventilation Technology in Underground Cave Construction

地下洞室施工施工中,劳动者因接触粉尘、放射性物质和其他有毒、有害物质等因素会引起职业病,防治职业病,保护劳动者健康是企业责任,也是企业可持续发展的基础,在大力提倡“以人为本”为指导思想的今天,如何为劳动者提供良好的作业环境一直是地下洞室施工中的难题。针对此长期困扰施工的老大难问题,澜沧江上游水电站输水发电系统工程施工中,首次研发了智能通风及人群健康在线监测系统,通过在工作面安装污染物浓度监测传感器,实时在线采集地下洞室污染物浓度、监控风流状态,通过智能通风系统的运算,自动调整供风量大小,保证地下洞室的通风质量,改善施工环境,保障了现场人员健康。管理人员通过工地监控中心、微信小程序实时观察洞内污染物含量,实现“地下工程施工地面化”。

During the construction of underground caverns,workers may develop occupational diseases due to exposure to dust,radioactive substances,and other toxic and harmful substances.Preventing and treating occupational diseases and protecting the health of workers are corporate responsibilities and the foundation of sustainable development for enterprises.In today's era of vigorously promoting the guiding ideology of"people-oriented",how to provide a good working environment for workers has always been a difficult problem in underground tunnel construction.In response to this long-standing problem that has plagued construction,an intelligent ventilation and online monitoring system for human health has been developed for the first time during the construction of the water transmission and power generation system of the Lancang River upstream hydropower station.By installing pollutant concentration monitoring sensors on the working face,real-time online collection of underground cavern pollutant concentration and monitoring of airflow status can be achieved.Through the calculation of the intelligent ventilation system,the supply air volume is automatically adjusted to ensure the ventilation quality of the underground cavern,improve the construction environment,and safeguard the health of on-site personnel.Management personnel observe the real-time pollutant content inside the tunnel through the construction site monitoring center and WeChat mini program,achieving"underground engineering construction on the ground".
