谈紧邻地铁深基坑工程封闭止水措施

Discussion on sealing waterproofing measures of deep foundation engineering near the subway

以深圳某开发项目为例,通过对基坑支护设计时薄弱点的科学分析,采取了封闭止水防护措施,并从围护结构选型与施工技术两方面,阐述了封闭止水措施在实际工程中的应用,经监测数据表明,此次封闭止水措施取得了良好的施工效果。

Taking the development project in Shenzhen as an example,through scientifically analyzing the foundation support design defects,the paper applies sealing waterproofing measures,and describes the application of sealing waterproofing measures in actual engineering from two aspects of enclosure structure selection and construction technology. The monitoring data shows that: the above-mentioned sealing waterproofing measures have achieved good construction effect.
