浅谈泥浆技术在置换式塑性砼防渗墙施工中的应用

Application of slurry techniques to construct replacement plastic concrete cut-off walls

介绍了几个置换式塑性砼防渗墙施工项目中泥浆技术的应用情况,通过分析应用效果,说明了根据现场条件经试验确定泥浆性能(密度、粘度、泥皮厚度、失水量、稳定性、含砂率、pH值)标准值的重要性,并阐述了几种调整泥浆性能的方法。

The application status of slurry techniques to construct replacement plastic concrete cut-off walls in different engineering examples is introduced. Through analysing their application effects it showed the importance to detect and verify the standard values of slurry characteristic parameters(density, viscosity, thickness of mud-skin, water loss, stability, sand ratio and pH) by test in-situ. Several mothods for adjusting slurry performance are expounded.
