应急抢险抽排水技术的理论与实践

Theoretical and practical study on water pumping and drainage technique in emergency rescue

针对施工过程中发生的突涌水或透水灾害性事故,提出了应急抢险抽排水的基本原则,阐述了开展应急抢险抽排水时设备、管线及泵站的选型与布置方法,同时介绍了应急抽排水的供电系统与电气控制设备的基本要求。在多次实际抢险抽排水过程中,应用这些抽排水技术,快速、高效地完成了应急抢险抽排水任务,取得了较大的社会效益与经济效益,其经验可为类似抢险提供借鉴。

Aiming at the water burst and water inrush accidents during construction, the basic principles for the water pumping and drainage in emergency rescue are put forward, and the selection and layout of the equipment, pipeline and pumping station are described. The basic requirements of the power supply system and electrical control system are introduced. In several practi- cal cases, these techniques are used to finish the task in a quick and effective way, which has created huge social and economic benefits.
