摘　　要：介绍了重庆永川区某排水管道非开挖翻转内衬修复的设计、质量检测和工程应用情况。实践表明,对于DN600病害管道,当设计水压为60 kPa、软管的厚度为9 mm时,采用双层结构,内、外层幅宽分别为1 770、1 700 mm,加工后的软管接缝处抗拉强度为7.45 MPa,能够满足施工要求。对长度约为140 m的病害管道进行原位修复后,固化管内壁无鼓胀、裂纹、褶皱等现象,初始结构性能满足《城镇排水管道非开挖修复更新工程技术规程》(CJJ/T 210-2014)要求。The design,quality inspection and engineering application of trenchless rotary cured-inplace pipe( PICC) for a drainage pipeline in Yongchuan District,Chongqing were introduced. The results show that as for a DN600 harmed pipeline,with designed water pressure of 6 k Pa,designed hose thickness of about 9 mm,and the inner and outer layer widths of about 1 770 mm and 1 700 mm respectively,the tensile strength of the hose joint is about 7. 45 MPa,which could meet the construction requirements. After rehabilitation of a 140 m harmed pipeline,there were no bulging,cracks and wrinkles for inner wall of the cured pipe. The initial structural performance meets the requirements of Technical Specification for Trenchless Rehabilitation and Renewal of Urban Sewer Pipeline( CJJ/T 210-2014).
