Ten thousand years of dignified and profound, water is the source of life. However, with the acceleration of urbanization and industrialization, the water environment faces unprecedented challenges. The upgrading and transformation of sewage pipeline network is an important measure to improve the water environment. As an important city in Hubei Province, Shiyan City has always attached great importance to the upgrading and transformation of sewage pipeline network. This article will introduce the acceptance standards and norms of the Shiyan sewage pipeline network upgrading and transformation project. I. Standards and norms for sewage pipe materials The materials of the sewage pipes are the foundation of the entire sewer project. The quality of the materials directly affects the safety, durability and sustainability of the project. The acceptance standards and norms for sewage pipe materials are as follows: 1. The sewage pipes should be made of high-density polyethylene (HDPE) materials with a density greater than 930kg/m3, which meet the requirements of GB/T19472.1-2004. 2. The pipe wall thickness of each pipe should be uniform, and the deviation should not be greater than ±10% of the nominal wall thickness. 3. The pipe should be flat, smooth, free of cracks, and have no visible defects such as air bubbles or impurities. II. Standards and norms for pipeline construction The pipeline construction stage is the key stage of the entire sewage pipeline network upgrading and transformation project. The construction quality directly affects the service life and safety of the pipeline network. The acceptance standards and norms for pipeline construction are as follows: 1. The construction process should strictly follow the construction plan, and the construction site must be kept clean and tidy. 2. The construction workers should have the corresponding qualifications and professional skills, and the construction team leader must have the corresponding construction management certificate. 3. The construction should strictly conform to relevant standards and regulations, and the pipeline laying should be smooth, with a good slope and tightly connected. The pipeline well should be installed in accordance with the design requirements. III. Standards and norms for sewage pipeline network commissioning After the pipeline construction is completed, the sewage pipeline network commissioning is carried out to ensure that the pipeline network can operate normally. The acceptance standards and norms for sewage pipeline network commissioning are as follows: 1. The sewage pipeline network commissioning should be conducted by professional personnel with relevant qualifications. 2. The commissioning process should be strictly in accordance with relevant standards and operating procedures, and the commissioning results should be recorded in detail in the commissioning report. 3. After the commissioning is completed, a trial operation should be carried out to further verify the running status of the sewage pipeline network, and the operation status should be recorded in detail. In conclusion, the upgrading and transformation of the sewage pipeline network is an important measure to protect the water environment. In the process of upgrading and transformation, it is necessary to strictly adhere to relevant standards and norms, and ensure the quality of materials, construction and commissioning. It is believed that with the continuous upgrading and transformation of the sewage pipeline network, Shiyan City's water environment will become more beautiful.
