[0002] The buried depth of a pipeline refers to the vertical distance from the ground surface to the bottom of the pipeline where it is buried. This distance is affected by many factors, including the anti-floating requirements when the pipeline is empty, the ground load and the bearing capacity of the pipeline. In order to protect the buried pipeline from damage by ground facilities and vehicles, the soil cover on the top of the pipe is generally not less than 0.7 meters. When crossing a river or a railway, this distance is usually not less than 1.2 meters. In addition, if the pipeline is buried under a rice field or a sidewalk, the soil cover on the top of the pipe shall not be less than 0.8 meters; if the pipeline is under a road, the soil cover on the top of the pipe shall not be less than 1 meter. In addition to the special circumstances mentioned above, the buried depth of the pipeline is also determined by technical and economic comparisons. Under the premise of meeting these conditions, a deeper buried depth should be selected as much as possible to reduce the amount of excavation and backfilling, thereby reducing the project cost.
