1. Cable marker posts should be installed directly above the pipeline. When used as corner piles, cable marker posts 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 post.

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 posts can be increased by 100m. In special areas, the specific laying standards and regulations shall be followed for the laying of pipeline marker posts!

3. Cable marker posts 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.

Construction precautions for cable marker posts

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.

Preparation work is important:

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

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

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

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

Attention should be paid to the operation of marker posts:

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. 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. 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 posts must be set up. Relevant data must be written on the marker post. For example: burial depth, crossing size, etc.

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. 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.
