Scope

Scope: The water supply industry of Shanghai City; Main technical content: Aiming at the problems of frequent leaks and pipe bursts caused by the serious aging of Shanghai's water supply pipe network. At present, more and more projects are using non-excavation technology to repair water supply pipelines. After on-site investigation and expert advice, and listening to the opinions of various units in the industry, we finally selected a widely used and technically mature process to formulate this group standard. This group standard highlights the local characteristics of Shanghai, meets the development needs of urban construction, and its technical requirements are not lower than the relevant provisions of national standards, industry standards, and mandatory local standards. It is operable and forward-looking. In the face of the actual needs of non-excavation repair projects for urban water supply pipe networks, we focus on the safety, practicality, and innovation of non-excavation repair technology to promote technological progress in the industry. The non-excavation repair technologies involved in this group standard include the following eight types: 1. Room-temperature curing method, 2. Steam curing method, 3. Hot water curing method, 4. Ultraviolet curing method, 5. Laminated in-situ curing method, 6. In-situ thermoplastic molding method, 7. Stainless steel lining method, 8. Polyurethane spray lining method
