摘　　要：基于输电线路基础机械化施工的需求,面对建设生态文明建设中环境保护和水土保持的要求,通过对比分析现有的杆塔基础施工中常用的成孔方式,提出了适用于山区大口径桩孔施工的装备及相应配套的施工工法,有效解决了山区大口径杆塔基础无机械化施工设备可用的困境。基于货运索道运输,钻机进行了功能模块化设计,拆装运输方便,可解决山区非道路进场的难题。钻机配置创新性的外钻进内排渣、无循环液、机械连续排渣系统及相应钻具,丰富了山区基础施工装备配置体系。Based on the demand of mechanized construction of transmission line foundations and the requirements of environmental protection and water conservation in ecological civilization construction,this paper proposes the equipment and corresponding supporting construction methods suitable for large-diameter pile construction in mountainous areas,which effectively solves the dilemma that there is no mechanized equipment available for large-diameter tower foundation in mountainous areas.Based on the freight ropeway transportation,the drilling machine has been designed with functional modularization,which makes assembly,disassembly and transportation convenient and can solve the problem of non-road approach in mountainous areas.The innovative external drilling and internal discharge,no circulating fluid,mechanical continuous cuttings discharge system and corresponding drilling tools have enriched the basic construction equipment configuration system in mountainous areas.
