大型边坡快速开挖防护施工技术

为提高大型边坡施工效率,保障施工安全,通过传统工艺改进,工作面和工艺工序在空间和时间上的优化,拉长流水工作面。将边坡开挖一级防护一级细分为一级分三层开挖,并利用小高差优势引进履带式锚索钻机打孔作业。避免了边坡防护脚手架搭设,降低施工安全风险;减少大量工日,具有显著的经济效益。

Construction Technology of Rapid Excavation and Protection for Large Slope

In order to improve the construction efficiency of large-scale slopes and ensure the safety of construction,through the improvement of traditional crafts and the optimization of the working face and the technological process in space and time,it elongates the flowing working face.The first-level protection for slope excavation is subdivided into first-level and three-layer excavation,and the advantage of small height difference is used to introduce crawler anchor drilling rigs for drilling operations.It avoids the slope protective scaffolding,reduces the construction safety risks,and reduces a large number of working days,so it has significant economic benefits.
