拉哇水电站右岸高陡边坡快速开挖支护施工技术OA
Rapid Excavation Support Construction Technology for High and Steep Slope on the Right Bank of Lawa Hydropower Station
该工程边坡高陡,受现场环境因素影响较大,综合拉哇水电站整体施工规划,需对开挖支护工艺进行优化,笔者通过改变开挖支护工作面与施工便道空间位置关系,优化爆破设计参数,采取蹬渣作业,快速支护等一系列方法以保证边坡在安全的提前下快速下卧,实现右岸高陡边坡的快速施工,为后续水利、矿山等多个领域边坡快速开挖支护施工提供重要的参考依据.
The slope of this project is high and steep,which is greatly affected by site environmental factors.Considering the overall construction planning of Lawa Hydropower Station,it is necessary to optimize the exca-vation and support technology.In this paper,a series of methods such as changing the spatial position relation-ship between excavation and support face and construction walkway,optimizing blasting design parameters,and adopting slag pushing-off operati…查看全部>>
