隧道工程喷膜防水技术的发展与应用现状

Application and Development of a Sprayed Waterproof Membrane for Tunnels

文章从国内外隧道工程喷膜防水技术的发展阶段、技术原理、工程应用等方面进行分析,论述了该技术的应用与发展趋势。喷膜防水技术主要包括喷膜材料及成膜机理、喷膜机具、施工工艺几大部分,适用于复合式衬砌的暗挖隧道、沉管隧道、明挖隧道、隧道渗漏治理及其他相关地下工程结构。目前该技术已经在国内外较多的隧道工程中得到了应用,处于较大规模的应用阶段。随着相关工程应用实例逐步增多和研究工作的推进,该技术将具有良好的推广前景。

The application and development trends of the sprayed waterproof membrane technology used in tunnel- ling are discussed based on an analysis of development stages, basic principles and application in tunnels both at home and abroad. The sprayed waterproof membrane technique includes the material, polymerization mechanism, spray apparatus and construction technology, and this technique can be used in bored tunnels with compound linings, immersed tunnels, cut-and-cover tunnels, other underground works and for treatment of tunnel leakages. It has not been applied extensively yet, though it has been introduced to more and more tunnels all over the world recently. The prospects for this technique are bright as it is increasingly applied to various tunnels, and more achievements re- garding related research work are expected in the near future.
