基于防腐考虑的TPO防水施工技术

TPO Waterproof Construction Technology Based on the Anti-corrosion

在地下防水施工过程中,由于土壤被污染,普通防水材料容易被有机物腐蚀溶解,无法满足直接接触二氯乙烷等环境的防水要求。结合北京某住宅项目工程实例,探索TPO防水材料在特殊环境中的应用,并总结出了其技术特点及应用要点,介绍了TPO防水卷材具体施工工艺流程及关键节点做法,取得良好的经济和环保效益。

During the construction of the underground waterproof engineering, it is found that ordinary building waterproof materials can be corroded easily, the construction can’ t meet the requirements for the direct contact with the dichloromethane（ CH2 Cl2 ） because of the soil contamination. Combining with the engineering example of some residential buildings in Beijing, this paper explores the TPO system application in the particular environment, and summarizes the characteristics for the technical and the application of the TPO system. Moreover, it introduces the construction process and key joints structure of TPO system, then good economic and environmental benefits are achieved.
