Comprehensive pipe gallery ventilation interval unit and pipe gallery fire treatment method
The invention provides a comprehensive pipe gallery ventilation interval unit and a pipe gallery fire treatment method. The comprehensive pipe gallery ventilation interval unit comprises a pipe gallery layer, wherein normally-closed fireproof doors are arranged at the two ends of the pipe gallery layer. A first ventilation opening and an air inlet fan which communicates with the first ventilation opening are arranged at the first end of the pipe gallery layer, and a second ventilation opening and an air exhaust fan which communicates with the second ventilation opening are arranged at the second end of the pipe gallery layer. At least one escape exit is arranged between the first ventilation opening and the second ventilation opening. At least one normally-open type fireproof separation mechanism is arranged between the normally-closed fireproof doors at the two ends of the pipe gallery layer and used for controlling the pipe gallery layer to be separated into a plurality of fireproof subareas or enabling the pipe gallery layer to be kept communicating. A fire extinguishing device is arranged in each fireproof subarea. By means of the comprehensive pipe gallery ventilation interval unit and the pipe gallery fire treatment method, the purpose that the number of ventilation structures, higher than the ground, of a comprehensive pipe gallery is reduced is achieved, and the situations that the fireproof separation requirement is met and smoke is exhausted in time after a fire accident occurs can be guaranteed.
本发明提供了一种综合管廊通风区间单元及管廊火灾处理方法，该综合管廊通风区间单元包括管廊层，管廊层的两端分别设有常闭防火门；管廊层的第一端设有第一通风口和与第一通风口连通的进风风机，管廊层的第二端设有第二通风口和与第二通风口连通的排风风机；第一通风口和第二通风口之间设有至少一个逃生口；管廊层中两端的常闭防火门之间设有至少一个常开式防火分隔机构，用于控制将管廊层隔断成多个防火分区或者使管廊层保持连通；各个防火分区中均设有灭火装置。通过本发明，实现了减少综合管廊的高出地面的通风构筑物，并且能够保障满足防火分隔要求和火灾事故后的及时排烟。
