- 摘要:
- 中國工程建設標準化協(xié)會標準《城鎮(zhèn)排水管道非開挖修復工程施工及驗收規(guī)程》（T/CECS 717—2020）已發(fā)布實施，詳細介紹了該規(guī)程的創(chuàng)新內(nèi)容，包含目前行業(yè)中先進適用的14種非開挖修復技術的施工要求及質(zhì)量驗收相關規(guī)定。重點解析了規(guī)程中紫外光固化玻纖增強樹脂修復材料的彎曲強度、彎曲模量等技術指標的制定依據(jù)，管道閉氣試驗的具體判定方法，以及指導工程質(zhì)量檢驗與驗收的主要內(nèi)容。該規(guī)程依據(jù)當前行業(yè)發(fā)展及市場需求對非開挖修復技術相關材料、工藝及驗收提出了合理適用的要求，對推動非開挖修復技術發(fā)展具有重大意義。
- 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.
