摘要
城市综合管廊已成为城市基础设施建设重要的一部分,然而对其应急排水设计目前仍缺乏充分思考.研究以南方某城市地下深埋综合管廊为例,综合考虑管廊开口处进水、管廊结构缝处渗漏水、管廊接出口渗漏水、管廊内冲洗排水、检修放空排水、供水管道渗漏水和供水管道爆管排水 7 种排水;针对不同规模的供水爆管漏失面积,提出相应的应急排水措施,包括提高日常排水泵流量,设置应急排水泵,调动移动抽水车;最后,研究建立管廊内给水管爆漏应急预案,提出爆管突发事件的监测要求和应急处置流程,以期最大限度地减少突发性爆管造成的影响.研究成果对综合管廊供水管道安全运行及应急排水设计具有重要的指导意义.
Abstract
Urban utility tunnel has become an important part of urban infrastructure construction,but the design of emergency drainage is still lacking of sufficient consideration.In this study,a deep-buried underground utility tunnel in a southern city was taken as an example,and seven kinds of drainage were comprehensively considered,including water inlet at the opening of the utility tunnel,water leakage at the structural joint of the utility tunnel,water leakage at the outlet of the utility tunnel,washing drainage in the utility tunnel,maintenance and emptying drainage,water leakage in the water supply pipeline and water supply pipeline burst drainage.According to the leakage area of water supply burst pipe of different scale,the corresponding emergency drainage measures were put forward,including increasing the daily discharge of drainage pump,setting up emergency drainage pump and mobilizing mobile pumping truck.Finally,the emergency plan of water supply pipe leakage in the utility tunnel was studied and established,and the monitoring requirements and emergency disposal process of pipe explosion emergencies were put forward,in order to minimize the impact caused by sudden pipe explosion.The research results have important guiding significance for the safe operation and emergency drainage design of the water supply pipeline in the utility tunnel.
