地铁工程地下水资源回收利用系统研究

Research on the Groundwater Resource Recovery and Utilization System in Subway Engineering

地下水资源回收利用一直是地铁工程环境保护和节能减排的热点问题。在地铁车站明挖基坑中一般设置有降水井,通常做法是将地下水抽到地面进行简单处理后直接排放,造成了严重的水资源浪费。基于此,文章以福建省沿海富水砂卵石、淤泥质地层为研究对象,比选节水措施,通过一种地下水资源回收利用自动控制系统实时调控围挡喷淋、主体结构混凝土养护等,对环境保护管理、职业健康管理及工程质量控制等方面具有一定的应用价值。

The groundwater resource recycling has always been a hot problem in the underground engineering environment protection, energy conservation and emissions reduction. There is usually a dewatering well in the open excavation foundation pit of subway station. The groundwater is pumped to the surface for simple treatment and then discharged directly, which results in a serious waste of water resource. Based on this, the paper takes the water-rich sand, pebble and silt layer along the coast of Fujian Province as the research object to compare and select the water-saving measures. An automatic control system of groundwater resource recovery and utilization is used to adjust and control the spraying of enclosure and the concrete maintenance of main structure in real time, which has certain application value in environmental protection management, occupational health management and engineering quality control.
