25、 图线路复测要以直线桩作为测量基点，用正倒镜分中法来检查塔位中心桩。正倒镜得到的两点A、B，取 AB的中点 C，如果 C点与原桩位相同（即为0 时），可以确定该直线塔桩位是正确的。有误差时，当以两相邻直线桩为基准，允许横线路方向偏移不大于50mm（即允许50mm）。若杆位中心桩有偏差时，应取杆位桩C点为改正后的杆桩。转角杆桩位复测：线路转角的角度值应用测回法进行测量。测得的角度值应满足与原设计值之差不大于130。实测角度值与设计角度值不相符时，应查明原因。若确实证明角度误差不是相邻桩位有误差造成的，则应做好记录，报技术部门协同设计单位妥善处理。丢桩补测线路复测过程中如发现杆桩丢失时，应根据线路

26、塔位明细表、纵断面图进行补测定桩。补测丢失桩的施工方法与复测相同。补桩中精度要求：有条件时使用半站仪或全站仪进行测距。用经纬仪视距法测距，两测回之差应满足不大于档距的%。采用钢卷尺直线测量时，两次测值之差不得超过档距的%。文档编码:CC10F7T9F1Y3 HF8B10H6S7Q2 ZV7K8I8W7H5文档编码:CC10F7T9F1Y3 HF8B10H6S7Q2 ZV7K8I8W7H5文档编码:CC10F7T9F1Y3 HF8B10H6S7Q2 ZV7K8I8W7H5文档编码:CC10F7T9F1Y3 HF8B10H6S7Q2 ZV7K8I8W7H5文档编码:CC10F7T9F1Y3 HF8
