摘　　要：入岩垂直防渗墙的施工技术在各类垃圾填埋场垂直防渗项目、水利工程和深基坑止水工程等领域均有广泛应用。结合工程实例,详细介绍了入岩防渗墙的墙体布置、钻孔、注浆、膨润土填充等各个环节的施工技术和注意事项,阐述了入岩防渗墙施工的原理和策略,以及目前常用的水泥浆注浆工艺和高压注浆工艺,对入岩防渗墙的施工及其质量保证提出了建议。The construction technology of vertical anti-seepage wall into rock has been widely used in all kinds of vertical anti-seepage projects of landfill,water conservancy projects and deep foundation pit water sealing projects.This paper introduces in detail the construction technology and precautions of wall layout,drilling,grouting,bentonite filling and wall top filling of the rock-injected seepage-proof wall.It also explains the principle and strategy of construction and the currently commonly used cement slurry grouting process and high-pressure grouting process.Finally,this paper puts forward suggestions on the construction and quality assurance of the rock-injected seepage-proof wall.
