帷幕注浆止浆岩盘施工技术

Curtain grouting borehole occluding laccolite construction technology

指出帷幕注浆是通过隧道富水带一种非常有效的施工方法,而止浆岩盘的成功与否是帷幕注浆施工的关键所在,介绍了在马鹿箐隧道施工中,根据不同的地下涌水等地质情况建造不同止浆岩盘的工艺参数等,从而为进一步推广该技术提供了实践经验。

The author points out that the curtain grouting is a kind of effective construction method of crossing the water enriched zone in tunnel, but the success of borehole occluding laccolite is the key of curtain grouting construction. The author introduces that in the Maluqing tunnel construction, it selects different technology indexes of occluding laccolite according to different geological situations, such as underground water, thus providing practical experiences for further improving this technology.
