新型防水系统在阿联酋纳吉马特项目地下箱涵结构中的应用

摘要

The Water Proofing System for underground culvert of NAJMAT project in UAE shall be of high performance and properties to withstand complicated conditions, such as water resistance against sea water pressure of 10 m depth, hot weather resistance, and chemical resistance of dilute acids, dilute alkalis, sulphates and chlorides etc. This paper introduces the application of the new water proofing system mainly consist of PVC membrane and water stop belts in the project, and the material property, layout and section design, method statement for installation and site inspection & testing. The result shows that the new water proofing system performs a remarkable function in compliance with the specified requirement.%阿联酋纳吉玛特(NAJMAT)项目地下箱涵工程的防水系统需要长期经受多种恶劣条件的综合作用,如10 m深海水压力和浸泡,以及耐高温气候、酸、碱、硫酸盐、氯离子腐蚀等.文章介绍以PVC防水膜和止水带为主要结构的新型防水系统在工程项目中的应用,对其材料特性、结构设计、施工工艺流程和现场检验情况进行介绍.结果表明,该新型防水系统防水作用明显,满足设计要求.
