扩大头锚杆挡土墙的施工技术浅析

On the Construction Technology to Expand Head Bolt Retaining Walls

扩大头锚杆挡土墙是近些年发展起来用于加固和增强边坡或开挖土体的复合挡土墙技术。扩大头锚杆挡土墙的施工减少了大量土方开挖,避免不良地质情况下边坡的塌方。本文主要结合康达尔花园五期工程的实际情况,对扩大头锚杆挡土墙的施工技术做了简要分析。

expanding head bolt retaining wall is the retaining walls technology developed in recent years for composite reinforcement and enhanced slope or excavation of soil .The construction of expanding head bolt retaining wall is to reduce a large number of earth excavation, and avoid slope collapse in adverse geological conditions.Combined with the actual situation of the the Candai garden engineering in fiveth phase, this paper made a brief analysis of the expanding the head bolt retaining wail construction technology.
