摘要:

为保证基坑降水工程中回灌水满足济南泉域地下水系统的水质要求，研制了基坑工程降水回灌一体化装置。该装置包括回灌主机和集水箱2个部分，主要组件由水泵、过滤器、压力罐、电控系統、集水箱、回灌井管材等构成。介绍了回灌设备工作原理、技术特色。通过济南轨道交通R1线大杨庄站基坑降水工程的成功应用，验证了该基坑工程降水回灌一体化装置取得的良好环境效益和社会效益。

Abstract:

In order to ensure that the recharge water in the foundation pit dewatering project meets the water quality requirements of the spring groundwater system in Jinan, an integrated dewatering and recharge apparatus for foundation pit projects has been developed. The apparatus consists of two parts: recharge engine and water collection tank. The main components are water pump, filter, pressurizing tank, electronic control system, water collection tank and recharge well tubing. The working principle and technical characteristics of the recharge apparatus are introduced. Through the successful application in the foundation pit dewatering project of Dayangzhuang Station on Line R1 of Jinan Rail Transit, the integrated dewatering and recharge apparatus for the foundation pit project has achieved good environmental and social benefits.
