- Title:
- Compilation of Technical Specification of Yunnan for Trench-less Rehabilitation of Water-supply and Sewer Pipeline: A Systematic Review
- Keywords:
- urban water-supply and sewer pipeline; trenchless rehabilitation; pipeline inspection and evaluation; local standard
- 摘要:
- 《云南省城镇给排水管道非开挖修复技术规程》（DBJ53/T—159—2024）已于2024年11月1日正式实施，相较于现行的行业标准《城镇排水管道非开挖修复更新工程技术规程》（CJJ/T 210 —2014）及《城镇给水管道非开挖修复更新工程技术规程》（CJJ/T 244—2016），该规程结合云南实际情况遴选了9项成熟且适用的给排水管道非开挖修复技术，将给水和排水管道非开挖修复技术标准合并编制，并重点补充和完善管道检测与评估、水力计算等内容，使之更具系统性和可操作性，对云南省的给排水管道非开挖修复工程开展具有重要的指导作用，也可为其他类似地区的工程提供参考。
- Abstract:
- The Technical Specification of Yunnan for Trench?less Rehabilitation of Water-supply and Sewer Pipeline （DBJ53/T-159-2024） was officially implemented on November 1, 2024. Compared to the current industry standards—Technical Specification for Trenchless Rehabilitation and Renewal of Urban Sewer Pipeline（CJJ/T 210-2014） and Technical Specification for Trenchless Rehabilitation and Renewal of Urban Water Supply Pipelines（CJJ/T 244-2016）, this regulation includes 9 mature and applicable trenchless repair technologies for water-supply and drainage pipelines based on Yunnan’s actual conditions. Building upon these the two industry standards, it improves the content resulted to pipeline inspection and evaluation, hydraulic calculation. These improvements make the specification more systematic and practical, providing important guidance for trenchless rehabilitation projects of water-supply and drainage pipelines in Yunnan Province. It can also serve as a reference in other regions.
