Application of Controllable Squeezed Composite Paste High-pressure Pulsation Grouting Technology in the Sand and Gravel Formations Foundation Seepage Treatment in Middle Line of the South-to-north Water Transfer Project

文章介绍了最新开发的可控挤入复合膏浆高压脉动灌浆技术应用于砂卵石层处理的施工工艺,并与传统的工艺进行优劣势对比,阐述了可控挤入复合膏浆高压脉动灌浆技术应用于砂卵石层的防渗处理的优势。实践证明,将可控挤入复合膏浆高压脉动灌浆技术应用于南水北调中线砂卵石底层地基的防渗处理中不仅工艺简便、经济可行,并且还取得了良好的灌浆效果。

Firstly, this paper introduces the construction process of controllable squeezed composite paste high-pressure pulsation grouting technology for sand and gravel treatment, and compares it with the traditional technology, and expounds the advantages of its application in sand and gravel foundation seepage treatment. Practice has proved that the application of controllable squeezed composite paste high-pressure pulsation grouting technology in sand and gravel foundation seepage treatment in the middle line of the South-to-north Water Transfer Project is simple, economical and feasible, and it also has achieved good grouting effect.
