轨道交通上盖开发车辆基地盖板下火灾探测器选用及改进

The selection and improvement of fire detectors under the cover of the vehicle base of the development of the railway superstructure

适用于轨道交通车辆基地高大空间的火灾探测器主要有三种,分别为线型光束感烟火灾探测器、吸气式感烟火灾探测器和图像型火焰探测器。但在实际工程中,几种探测器都不能非常好的适用。针对工程实际应用情况,对轨道交通上盖开发车辆基地盖板下火灾探测器的选择及安装改进进行研究,以期为此类项目的火灾自动报警系统设计及安装提供参考。

There are three main types of fire detectors applicable to the high space of railroad vehicle base,which are linear beam smoke and fire detectors,aspi-rated smoke and fire detectors and image type flame detectors.However,in the actual engineering,sever-al detectors are not very well applicable.In view of the actual application of the project,the selection and installation improvement of fire detectors under the cover of the vehicle base of rail transit superstructure development are studied with a view to providing reference for the design and installation of automatic fire alarm systems for such projects.
