随着城市建设的发展,地下工程的建设也越来越多、利用率也越来越高。在地下工程施工中,因地质条件的不同,地下水的处理问题便成为地下基坑开挖中一个至关重要的问题,它的处理效果直接影响到工程的质量、安全和进度。本文笔者结合某工程地下基坑施工实例,对井点降水技术处理地下水作以阐述,对以后同类工程中这一技术的应用有借鉴意义。 With the development of urban construction, the construction of underground engineering is also more and more, the utilization rate is also getting higher and higher. In the process of underground engineering construction, due to different geological conditions, the problem of underground water treatment becomes a crucial issue in the excavation of underground excavation. Its treatment effect has a direct impact on the quality, safety and progress of the project. In this paper, the author combined with a construction example of underground excavation, the well point precipitation technology to deal with the groundwater to elaborate on the similar projects in this technology for reference.
