- Abstract:
- The Specification for Construction and Acceptance of Trenchless Rehabilitation Engineering of Urban Drainage Pipeline（T/CECS 717-2020）issued by China Association for Engineering Construction Standardization has been issued and implemented. The innovative contents of the new specification were introduced in detail, including the relevant provisions of 14 advanced and applicable construction methods and quality acceptance regulations in the current industry. We focused on the formulated basis of the important technical index such as the bending strength and the bending modulus of UV curable glass fiber reinforced resin rehabilitation material, the specific judgment method of close gas test and the main content that guided quality inspection and acceptance for drainage pipeline. According to current industry development and requirements, this specification put forward reasonably applicable requirements for materials, construction technology processes and acceptance related to trenchless rehabilitation technology, which played an important role in promoting the development of trenchless rehabilitation technology.
