标志桩在操作方面需要注意
Attention should be paid to the operation of marker piles
1、测量放线的基准点一定要采用GPS定位，其中放线基准点是指设计控制桩和水准基桩。
1. GPS positioning must be adopted for the datum point of Surveying and setting out, among which the datum point of setting out refers to the design control pile and benchmark pile.
2、一定要按照图纸的作业要求设置控制桩，一定要表明桩号、里程、地面标高、转角高度等数据。
2. Control piles must be set according to the operation requirements of the drawings, and the data such as pile number, mileage, ground elevation, corner height, etc. must be indicated.
3、在定测资料和平面或是断面图纸上表明地下的障碍物，其次是，要保证线路和地下构筑物交叉两侧的控制范围为3米，同时，必须要设置警告牌和标志桩。标志桩上必须要写上相关的数据。比如：埋深，交叉尺寸等。
3. Indicate the underground obstacles on the location survey data and plane or section drawings. Secondly, ensure that the control range of both sides of the line and underground structure crossing is 3M. At the same time, warning signs and marker posts must be set. The relevant data must be written on the marker post. For example: buried depth, cross size, etc.
4、关于划线方面，要根据轴线和标志桩的界限之间拉一根绳子，撒上白石灰划线。完成划线，要清理现场的障碍物。
4. As for the marking, a rope shall be drawn between the axis and the boundary of the marker pile, and white lime shall be sprinkled for marking. Complete the marking and clear the obstacles on site.
5、关于移桩方面，是在划线完成之后打扫清理之前，将所有需要的线管桩平移到土堆的旁边，范围控制在0.3m。
5. As for the pile moving, before the cleaning and cleaning after the completion of the marking, all the required line pipe piles shall be moved to the side of the soil pile, and the range shall be controlled at 0.3m.
