Subway station fire evacuation scissor stair pressurization air supply system
The invention relates to a subway station fire evacuation scissor stair pressurization air supply system. The system comprises a subway platform layer, a subway station hall layer, a scissor stair, a pressurization air supply pipe well and a plurality of pressurization air feeders, wherein a plurality of vertical metal pipelines connected with the pressurization air feeders are arranged in the pressurization air supply pipe well, and carry out independent pressurization air supply on two staircases of the scissor stair, a platform staircase front room and a station hall staircase front room so as to ensure that indoor positive pressure is kept when the scissor staircase and the staircase front room are in fire. Aiming at the problems of limited space of an underground station and fire evacuation design, the invention provides the novel high-fall subway station scissor stair pressurization air supply system under the condition of meeting functional design by utilizing the characteristics of mutual overlapping of scissor stairs, small quantity of subway station front rooms and small air volume, so that the ventilation design is optimized, the fire safety is further guaranteed, and the civil engineering scale of the underground station is reduced.
本发明涉及一种地铁车站火灾疏散用剪刀楼梯加压送风系统，包括地铁站台层、地铁站厅层、剪刀楼梯、加压送风管井以及多个加压送风机；其中，所述加压送风管井内设置有多个与加压送风机相连接的竖向金属管道，分别对剪刀楼梯的两个楼梯间以及站台楼梯前室、站厅楼梯前室独立加压送风，以保证剪刀楼梯与楼梯前室在火灾发生时，保持室内正压。本发明针对地下车站空间有限以及消防疏散设计存在的问题，利用剪刀楼梯相互重叠及地铁车站前室数量少，风量小的特点，在满足功能设计情况下，提出一种新型高落差地铁车站剪刀楼梯加压送风系统，优化了通风设计，进一步保证了消防安全，减少地下车站的土建规模。
