Requirements and distance standards for setting water supply marker posts

1, Basic setup requirements

The water supply pipe marker post refers to a marker set up on the pipeline or ground to clarify the direction, position, model, and other information of the water supply pipe line. In water supply engineering, in order to ensure the management and maintenance of the water supply network, it is necessary to set up marker posts according to the prescribed requirements to facilitate future pipeline maintenance and management.

2, Distance standard

1. The distance for setting up marker posts should comply with regulations. In urban main roads, important intersections, or places with intermediate bridges, tunnels, overpasses, and other transportation facilities, the distance between setting up marker posts should not exceed 50 meters;

2. In urban secondary roads, sections with a distance between main and secondary roads exceeding 300 meters, or sections without traffic facilities, the spacing between marker posts shall not exceed 100 meters;

3. In rural and tourist areas, the spacing between marker posts should not exceed 200 meters.

3, The height and identification of marker posts

The height of the marker post shall not be less than 0.8 meters and shall not exceed 1.5 meters;

On the identification, information such as pipeline name, type, specification, burial depth, laying time, and construction unit should be indicated;

3. The color of the marker posts shall be specified in accordance with relevant national standards: Class I pipelines shall be blue, Class II pipelines shall be green, Class III pipelines shall be yellow, and Class IV pipelines shall be red.

4, Summary

The setting requirements and distance standards for water supply pipe marker posts are the basic requirements for the setting of marker posts, and also an important guarantee for future management and maintenance. In water supply engineering, the setting of marker posts should comply with regulations, and the markings should be clear and clear for future management and use.
