1. Cable marker piles should be installed directly above the pipeline. When used as corner piles, cable marker piles should be installed directly above the midpoint of the corner section. When there are no installation conditions above the pipeline, it can be set up in the roadside green belt that is relatively close to the pipeline, and the suitability diagram of the pipeline pile can be indicated on the cable marker pile.

2、全封閉禁入道路不得設置電纜標志樁。電纜標志樁的安裝間距宜為100m。地面平坦、視礙少、管道路由順直的情況，電纜標志樁的安裝間距可大100m。特殊地段，具體鋪設規范制度進行管道標志樁的鋪設!

2. Cable markers shall not be installed on fully enclosed and restricted roads. The installation spacing of cable marker posts should be 100m. When the ground is flat, there are few visible obstacles, and the pipeline routing is smooth, the installation spacing of cable marker piles can be increased by 100m. In special areas, the specific laying standards and regulations shall be followed for the laying of pipeline marker piles!

3、電纜標志樁是埋設在天然氣高壓管線沿線以塑鋼、玻璃鋼、復合材質為主，涂有黃色標記的電纜走向標志樁，為起提示警示作用，標有“燃氣管道、燃氣電話、管線樁號、管線走向、電子巡檢信息鈕”，便于巡線搶修人員迅速找準管線位置，贏得搶修時機。根據《城鎮燃氣管理條例》第三十六條要求，擅自拆除和移動天然氣高壓管線上埋設的電纜標志樁屬于違法行為。

3. Cable marker stakes are mainly made of plastic steel, fiberglass, and composite materials buried along natural gas high-pressure pipelines. They are painted with yellow markings and are marked with "gas pipeline, gas telephone, pipeline pile number, pipeline direction, and electronic inspection information button" to serve as a warning. This facilitates line patrol and repair personnel to quickly locate the pipeline position and win the opportunity for repair. According to Article 36 of the Urban Gas Management Regulations, it is illegal to dismantle and move cable markers buried on high-pressure natural gas pipelines without authorization.

電纜標志樁施工注意事項

Construction precautions for cable marker piles

“七大”步驟流程：準備的工作——相關儀器的檢查和矯正——進行測量放線——固定交樁——規劃線路——調整交樁——完工后需要記錄相關信息。

The process of the "Seven Major" steps: preparation work - inspection and correction of relevant instruments - measurement and setting out - fixing of stakes - planning of routes - adjustment of stakes - recording of relevant information after completion.

準備工作重要：

Preparation work is important:

1、詳細查看研究放線區域的完整的施工作業圖紙。

1. Detailed review of the complete construction operation drawings for the research and layout area.

2、提前準備交樁記錄需要的表格及了解接樁組成人員便于溝通。

2. Prepare the necessary forms for pile handover records in advance and understand the personnel responsible for pile handover for easy communication.

3、準備符合要求的測量儀器、木樁、標筆、白石灰以及其他工具。

3. Prepare measuring instruments, wooden stakes, markers, lime, and other tools that meet the requirements.

4、將需要測量放線使用的工具進行矯正，還需要保證這些工具必須在規定的有效期范圍之內。

4. Correct the tools used for measuring and setting out, and ensure that these tools are within the specified validity period.

標志樁在操作方面需要注意：

Attention should be paid to the operation of marker posts:

1、測量放線的基準點一定要采用GPS定位，其中放線基準點是指設計控制樁和水準基樁。

1. The benchmark for measuring and setting out must be determined using GPS positioning, where the benchmark for setting out refers to the design control piles and leveling foundation piles.

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

2. It is necessary to set up control piles according to the requirements of the drawings, and indicate data such as pile number, mileage, ground elevation, and corner height.

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，要保證線路和地下構筑物交叉兩側的控制范圍為3米，同時，必須要設置警告牌和標志樁。標志樁上必須要寫上相關的數據。比如：埋深，交叉尺寸等。

3. Indicate underground obstacles on location survey data and plan or section drawings. Secondly, ensure that the control range on both sides of the intersection of the line and underground structures is 3 meters. At the same time, warning signs and marker stakes must be set up. Relevant data must be written on the marker post. For example: burial depth, crossing size, etc.

4、關于劃線方面，要根據軸線和標志樁的界限之間拉一根繩子，撒上白石灰劃線。完成劃線，要清理現場的障礙物。

4. Regarding the marking, a rope should be pulled between the axis and the boundary of the marker post, and white lime should be sprinkled to mark the line. Complete the marking and clear any obstacles on site.

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

5. Regarding pile relocation, it is necessary to move all required line pipe piles to the side of the soil pile after completing the marking and before cleaning, with a range controlled at 0.3m.
