1. The meaning of the buried depth standard of urban heating pipelines refers to the distance from the bottom of the pipe to the ground when the heating pipeline is laid underground according to the relevant national regulations and standards. The main purpose of this standard is to ensure the safe and stable operation of heating pipelines, and at the same time to avoid adverse effects on groundwater resources and the environment.
Second, the provisions of the buried depth standard of urban heating pipelines.
1.According to the "Technical Regulations on the Management of Urban Thermal Planning" and other relevant laws and regulations, the buried depth of urban heating pipelines should be comprehensively determined according to local groundwater level, soil properties, climatic conditions and other factors. Generally speaking, the buried depth of the heating pipe should be 0More than 7 meters to ensure the safety and stability of the pipeline.
2.For the high-temperature hot water heating system, due to the particularity of its pipe material, its burial depth should be appropriately increased, and the general requirement is 12 meters or more.
3.In special areas, such as subways, highways and other infrastructure, the buried depth of heating pipelines should be adjusted according to the actual situation to meet the safety requirements of the project.
3. Considerations for the buried depth standard of urban heating pipelines.
1.Groundwater level: Groundwater level is one of the important factors affecting the buried depth of heating pipes. Under normal circumstances, in areas with high groundwater levels, the buried depth of heating pipelines should be appropriately increased to prevent groundwater from scouring and corroding the pipelines.
2.Soil properties: Soil properties directly affect the bearing capacity and stability of heating pipelines. For areas with poor soil quality and unstable foundations, the buried depth of heating pipelines should be increased accordingly.
3.Climatic conditions: Climatic conditions have a certain influence on the frost heave and thaw of surface soils. In cold areas or in the case of low winter temperatures, the buried depth of the heating pipeline should be appropriately increased to prevent the pipeline rupture caused by soil frost heave.
4.Engineering safety: In the process of project construction, it is also necessary to fully consider the safety factors of the project. For areas with complex geological conditions and difficult construction, the buried depth of the heating pipeline should be adjusted according to the actual situation to ensure the smooth progress of the project.
