浅谈高原冰水沉积层隧道帷幕注浆施工技术

Discussion on Curtain Grouting Construction Technology of Tunnel in Ice-Water Sedimentary Layer

帷幕注浆是处理隧道洞身加固与防渗的一种重要技术,现已被广泛推广。文章以拉林铁路藏噶隧道1号横洞冰水沉积层段帷幕注浆施工为例,详细介绍了高原铁路隧道超前帷幕注浆施工技术的特点及施工过程,为其它隧道帷幕注浆施工提供有力的技术支撑和借鉴。

Curtain grouting is an important technology to deal with tunnel reinforcement and anti-seepage.It has been widely promoted.This paper took the curtain grouting construction of the 1st section of the Laidong railway Tibetan Mastiff tunnel as an example,and introduced in detail the characteristics and construction process of the advanced curtain grouting construction technology of the plateau railway tunnel,which provides strong technical support and reference for other tunnel curtain grouting construction.
