Attention shall be paid to the operation of sign piles:

1、測量放線(xiàn)的基準點(diǎn)一定要采用GPS定位，其中放線(xiàn)基準點(diǎn)是指設計控制樁和水準基樁。

1. GPS positioning must be adopted for the datum point of Surveying and setting out. The datum point of setting out refers to the design control pile and leveling pile.

2、一定要按照圖紙的作業(yè)要求設置控制樁，一定要表明樁號、里程、地面標高、轉角高度等數據。

2. The control piles must be set according to the operation requirements of the drawings, and the data such as pile number, mileage, ground elevation and corner height must be indicated.

3、在定測資料和平面或是斷面圖紙上表明地下的障礙物，其次是，要保證線(xiàn)路和地下構筑物交叉兩側的控制范圍為3米，同時(shí)，需要設置警告牌和標志樁。標志樁上需要寫(xiě)上相關(guān)的數據。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 on both sides of the intersection of the line and underground structures is 3M. At the same time, set warning signs and sign piles. Relevant data shall be written on the sign pile. For example, burial depth, crossing size, etc.

4、關(guān)于劃線(xiàn)方面，要根據軸線(xiàn)和標志樁的界限之間拉一根繩子，撒上白石灰劃線(xiàn)。完成劃線(xiàn)，要清理現場(chǎng)的障礙物。

4. As for the marking, a rope shall be pulled between the axis and the boundary of the sign pile, and white lime shall be sprinkled for marking. After finishing the marking, the obstacles on the site shall be cleared.

5、關(guān)于移樁方面，是在劃線(xiàn)完成之后打掃清理之前，將所有需要的線(xiàn)管樁平移到土堆的旁邊，范圍控制在0.3m。

5. In terms of pile moving, all required pipeline piles shall be moved to the side of the soil pile after the completion of marking and before cleaning, and the range shall be controlled within 0.3m.
