- 摘要:
- 中国工程建设标准化协会标准《城镇排水管道非开挖修复工程施工及验收规程》（T/CECS 717—2020）已发布实施，详细介绍了该规程的创新内容，包含目前行业中先进适用的14种非开挖修复技术的施工要求及质量验收相关规定。重点解析了规程中紫外光固化玻纤增强树脂修复材料的弯曲强度、弯曲模量等技术指标的制定依据，管道闭气试验的具体判定方法，以及指导工程质量检验与验收的主要内容。该规程依据当前行业发展及市场需求对非开挖修复技术相关材料、工艺及验收提出了合理适用的要求，对推动非开挖修复技术发展具有重大意义。
- 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.
