The marker post is often used as an indicator and warning sign for power cable laying, communication optical cable, gas pipeline, farmland water conservancy, railway, petroleum and petrochemical pipeline channel; It is also often used in downtown areas, scenic spots, green belts, bushes, and pipeline route indication on both sides of pipe jacking to serve as a warning. Therefore, it is correct to bury marker posts to serve a longer time and better warning.

Precautions for water supply marker post setting:

1. The marker post shall be placed above the pipe position, and the surface shall be clean and legible. If it is no longer above the pipeline, the translation distance shall be stated. Buried in the green belt less than 40 cm, and the long pile is buried in the green belt or farmland more than 40 cm.

2. Generally, the spacing of marker posts is 50m (longitudinal deviation ≯ 0.15 m), and the deviation from the centerline of the pipe position is ≯ 0.25 m.

3. The starting point, end point, tee joint and corner of the pipeline must be marked with the pipeline route for easy identification.

4. The warning words and telephone on the marker post must be placed towards the road or be visible when people pass by.

☆ The setting of warning signs is similar to that of marker posts

Numbering regulations for water supply marker posts

If it is designed to adopt the numbering method, it is composed of the numbering method of each enterprise or the first six digits of the project number plus the three digit sequence number. It is written on the pile in 5 cm high red Song typeface. For new projects, the pile location and number shall be indicated on the as built drawing, and the total number of identification piles and signboards shall be indicated on the lower left corner of the as built drawing.

Pipeline setting requirements

When two pipelines are laid in parallel and the horizontal spacing is 0.4 m to 1 m, the letters "G, Z, D" shall be marked on the signboard or marker post of the shorter pipeline, except for the corresponding signboard or vertical marker post above each pipeline Where, G represents high pressure pipeline, Z represents medium pressure pipeline, and D represents low pressure pipeline. The letter height on the sign board is 1 cm, and the letter on the marker post is written below the pile number. The letter height is the same as the pile number.
