摘要

After completion of the main structure of the urban underground utility tunnel, gallery is in confined space,which belongs to the limited space. When constructing in the gallery,in order to ensure the safety of working personnel and provide good working conditions of limited space, the internal space of utility tunnel must set up temporary ventilation and lighting facilities. Combined with the actual situation of Liupanshui urban comprehensive utility tunnel, the design and analysis of temporary ventilation and lighting in underground utility tunnel limited space is introduced in detail.%当城市地下综合管廊主体结构完工后,管廊处于一个半密闭的空间,属于有限空间,在管廊内部进行施工作业时,为了保证作业人员安全,提供良好有限空间作业条件,管廊内部必须设置临时通风及照明设施.结合六盘水城市地下综合管廊项目实际情况,对地下综合管廊有限空间作业的临时通风及照明设施进行设计和分析探讨.
