高压喷射灌浆技术一般用于水利工程的防渗处理,病库和堤坝堵漏。高压喷射灌浆法是一种采用高压水或高压浆液形成高速喷射流束,冲击、切割、破碎地层土体,并以水泥基质浆液填充、掺混其中,形成桩柱或板墙状的混结体,用以提高地基防渗或承载能力的施工技术。本文介绍了高压喷射灌浆防渗墙垂直防渗技术在彰武水库大坝截渗工程中的实际应用和施工体会。
High-pressure jet grouting technology is generally used for anti-seepage treatment of water conservancy projects, reservoirs and embankment plugging. High-pressure jet grouting is a kind of high-pressure jet or high-pressure slurry to form high-speed jet stream, impact, cutting, crushing the formation of soil, and cement matrix slurry filled, mixed therein to form a piling or wall-wall mixture , To improve the foundation seepage or carrying capacity of construction technology. This paper introduces the practical application and construction experience of vertical seepage prevention technology of high pressure jet grouting cutoff wall in Zhangwu reservoir dam seepage control project.
