塑性混凝土防渗墙是松散透水地基或坝体中常用的一种有效防渗方法,相比其他混凝土防渗墙,具有低强度、低弹模和大应变等特性,在以往水利水电工程中已得到广泛使用,近年来随着目前又一批抽水蓄能电站的兴建,开始在上、下库工程的面板堆石坝或心墙坝工程中应用,并且作为防渗体系的重要组成部分。本文结合黄河内蒙古河段某电站厂房工程实例,介绍了塑性混凝土防渗墙在较为复杂的地质条件下的施工技术与方法,为后续类似工程提供借鉴和参考。
Plastic concrete cutoff wall is an effective seepage prevention method commonly used in loosely permeable foundation or dam body. Compared with other concrete cutoff walls, the plastic concrete cutoff wall has the characteristics of low strength, low elastic modulus and large strain. In the past, water conservancy and hydropower projects Has been widely used. In recent years, with the construction of yet another batch of pumped storage power stations, it has started to be used in the face rockfill dam or core wall dam project of the upper and lower reservoir projects, and has also become an important part of the seepage prevention system. In this paper, combining with the engineering example of a power plant in Inner Mongolia section of Yellow River, the construction techniques and methods of plastic concrete impervious wall in more complicated geological conditions are introduced, which can provide reference and reference for similar projects in the future.
