Application and Development of a Sprayed Waterproof Membrane for Tunnels
(1 Key Laboratory of Transportation Tunnel Engineering, Ministry of Education, Southwest Jiaotong University, Chengdu 610031;2 School of Civil Engineering, Hope College, Southwest Jiaotong University, Chengdu 610400; 3 School of Life Science and Engineering, Southwest Jiaotong University, Chengdu 610031)
Abstract 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 regarding related research work are expected in the near future.
