Open/closed dual-purpose staircase for underground main power house of hydropower station
The invention discloses an open/closed dual-purpose staircase for an underground main power house of a hydropower station. The open/closed dual-purpose staircase comprises an open staircase, a firewall, a side-hung fireproof door, steel fireproof and smoke-proof roller shutters or double-layer inorganic cloth fireproof and smoke-proof roller shutters, a completed fire alarm system and a completed main power house smoke exhaust system, wherein the open staircase is constructed and is used for connecting all layers; the firewall is positioned on one side of the staircase; the side-hung fireproof door is arranged on the firewall; the steel fireproof and smoke-proof roller shutters or double-layer inorganic cloth fireproof and smoke-proof roller shutters are positioned on other unclosed side edges of the open staircase and have the fire endurance of more than or equal to 2 hours; the completed fire alarm system is linked with the fireproof roller shutters; and the completed main power house smoke exhaust system is linked with the fire alarm system. At ordinary times, the fireproof and smoke-proof roller shutters are completely lifted or half lifted, and the staircase is in an open state; and when a fire occurs, after a fire alarm signal is confirmed, all layers of fireproof and smoke-proof roller shutters are linked to simultaneously fall and completely fall once to form the closed staircase, and personnel are evacuated from the formed closed staircase through the side-hung fireproof door on the firewall. Therefore, the open/closed dual-purpose staircase can meet the requirement of the power station on operation at ordinary times and also can meet the requirement of personnel evacuation during the fire.
本发明公开了一种水电站地下主厂房的敞开/封闭两用楼梯间，包括已施工完成的连接各层的敞开楼梯,位于楼梯间一边的防火墙及该墙上设置的平开防火门,位于敞开楼梯间其它未封闭侧边设置的耐火极限大于等于2小时的钢质防火防烟卷帘或双层无机布防火防烟卷帘,已完成的火灾报警系统且与该防火卷帘联动,已完成的主厂房排烟系统且与火灾报警系统联动。平时防火防烟卷帘完全升起或半升起，楼梯间呈敞开状态，发生火灾时，在确认火警信号后联动各层防火防烟卷帘同时下落且一次完全落下形成封闭的楼梯间，人员通过防火墙上的平开防火门从形成的封闭楼梯间疏散。这样，既能满足电站平时运行的需要，又能满足火灾时人员疏散的要求。
