长大输水隧洞工程衬砌结构防水技术试验研究

Experimental study of liner waterproofing technology in a long and large water tunnel project

针对长大输水隧洞工程衬砌结构混凝土所要求的防水特性,进行了衬砌结构自防水混凝土研究和衬砌结构预埋式接缝防水技术研究,从注浆选材到施工工艺作了现场试验,并在工程应用中取得了良好的效果。

This paper introduces the study of liner self-waterproofing concrete and embedded seam waterproofing techniques, which were used in a long and large water tunnel project. It also introduces the selection of grouting materials and construction methods.
