天津市第一中心医院新址扩建项目深基坑降排水施工技术

Dewatering and Drainage Construction Technology of Deep Foundation Excavation for the New Site Expansion Project of Tianjin First Central Hospital

基坑降水作为土方开挖的必要环节和关键工序,降排水施工质量将直接影响到整个工程的质量、安全和进度。以天津市第一中心医院新址扩建项目为例,阐述了超大深基坑降排水施工的施工方法和关键工序,研制出一种基坑自动空压降排水壶形装置,总结出一套安全高效的降排水施工技术,保证了施工过程中的用电安全,提高了降排水施工的管理效率。

As the necessary link and key process of earthwork excavation,the foundation excavation dewatering will directly affect the quality,safety and progress of the whole project.Taking the new site expansion project of Tianjin First Central Hospital as an example,this paper expounds the construction method and key process of the super-deep deep foundation excavation drainage construction,and develops a foundation excavation automatic air pressure drop-out kettle-shaped device,summarizes a set of safe and efficient drainage construction technology.The drainage construction technology ensures the safety of electricity during the construction process,improves the management efficiency of the drainage construction.
