高压喷射灌浆防渗技术可用于水利工程的防渗处理,并且能够修复病库和堵漏堤坝。高压喷射灌浆法通过采用高压水或高压浆液,从而形成高速喷射流束,对于地层土体会起到冲击、切割作用,其中还会掺混水泥基质浆液,从而形成桩柱或板墙状的混结体,这种施工技术可以提高地基防渗和承载能力。当高压喷射灌浆技术得到成功应用时,我国就加强了对这项技术的推广和使用。本文就对高压喷射灌浆防渗技术在水库大坝基础处理中的应用进行了分析。
High-pressure jet grouting seepage control technology can be used for the seepage control of water conservancy projects, and can repair the reservoir and plug the dam. High-pressure jet grouting produces high-velocity jet streams by using high-pressure water or high-pressure slurry, which can impact and cut soil layers, mixing cement matrix slurries to form piles or wall-wall hybrids Body, this construction technology can improve seepage and bearing capacity of the foundation. When high-pressure jet grouting technology has been successfully applied, China has stepped up the promotion and use of this technology. This paper analyzes the application of high-pressure jet grouting seepage control technology in reservoir dam foundation treatment.
