摘　　要：喷涂聚脲弹性体技术是一种新型无溶剂、无污染的绿色施工技术。为了解决尼尔基水利枢纽工程混凝土蜗壳防渗及抗冲磨问题,首次大规模应用了喷涂聚脲弹性体技术。通过对聚脲弹性体材料特性、专门的喷涂设备、喷涂施工工艺及注意事项的介绍,为今后推广应用该技术提供了宝贵的经验。这种技术在解决水利水电工程中抗冲磨、抗渗及防腐蚀等方面具有广阔的应用前景。Spray Polyurea Elastic （SPUA） is new-fashioned technology of non-solvent and non-pollution adverse effect. In order to solve the problem of anti-abrasion and anti-seepage of concrete scroll case in Nierji Hydraulic Project, the technology is applied into this project. This paper describes the sorts and the properties of SPUA materials, the special spraying equipments, and construction skills as well as relevant details. Increasing the resistance of anti-abrasion and anti-seepage of concrete structures is a widely existing problem and a hard task. This paper will provide valuable references for other projects in the future.
