电力桩施工桩径大?
人工挖孔?
冲击钻、反循环钻机山地无水可用?
大型旋挖钻机进场困难?
但国家电网要求输电线路机械化施工,
怎么办?
三一SR155告诉你答案

施工概况
项目名称:黄石市大冶市某输变电工程
钻孔信息:桩径2.4m、桩长12m
地层特征:粉质黏土
施工工法:干孔作业,φ1.4+φ1.8+φ2.4m捞砂斗分级钻进


工法加持,潜能无限
考虑到国网项目“大孔浅桩”的桩基础特点及山地施工的特殊性,SR155整机尺寸小,重量仅48t,运输不超高,转场便捷,符合电力桩山地施工要求。但小机型同时也有施工桩径小的限制,SR155级别设备设计施工最大钻孔直径为1.5m。三一工法结合设备性能,为客户提供定制化的钻具设计,减轻主卷扬负载的同时,防止钻斗在回转、甩土过程中与履带及桅杆干涉,使SR155足以应对2.4m大桩施工需求。


客户说好才是真的好
SR155在电塔桩基础间频繁地转场施工,轻便灵活特点展露无遗。单桩成孔时间2h,平均工作油耗14L/h,高施工效率,低油耗,为客户节省了大量施工成本。机手也表示该设备施工有劲,甩土有力,动作灵活,戏称SR155为“小钢炮”。SR155不负众望,为输电线路机械化施工增添了浓墨重彩的一笔!
