电渗透防水防潮技术的工程应用

摘要

Waterproofing in underground engineering has been a difficult problem for a long time. The traditional technology has disadvantages of solving difficultly and recurring easily. Through engineering experimental research of electro⁃osmosis at one depot,this paper firstly introduces electro⁃osmosis technology and construction process in detail,then arranges electrodes and sup⁃plies pulse voltage force to reduce the project internal humidity and realize waterproofing by driving water to move to the engineer⁃ing outward rock mass by means of the electric field. The engineering application shows that the electro⁃osmosis waterproofing tech⁃nology has obvious effect,low operating cost,and good popularizing prospect.%　　地下工程防水防潮一直是工程界的难题，传统技术存在难根治、易反复的缺点。选择某一洞库进行电渗透技术工程试点研究：先详细介绍电渗透技术和施工工艺情况；再采用在工程内布置电极并施加脉冲电压的方法，利用电场力迫使水分向工程外岩体移动，达到降低工程内部湿度、防水防潮的目的。工程应用表明，电渗透防水防潮技术拥有效果明显、运行费用低等突出优点，具有推广前景。
