摘要
文章以广州地铁二号线“赤岗—鹭江区间隧道”工程为例,对EPDM弹性止水条和遇水膨胀止水条两种材料的各项性能指标进行了对比分析,阐述了EPDM弹性止水条的综合性能和施工技术要点。在实际工程中采用EPDM弹性止水条,较好地解决了当前国内盾构隧道的渗漏质量通病——管片衬砌接缝的防水问题。
Taking the transit tunnel project on Guangzhou metro Line 2 as an example, the paper analyzes and compares the characteristic indices of EPDM elastic water - stoppers and the swelling water - stoppers, describes the comprehensive properties and installation techniques of EPDM elastic water - stoppers. Application of EPDM elastic water - stoppers in metro projects has solved the problem - leakage through segment joints.
