【摘要】 原位固化法修复技术是目前国内使用较多的城市排水管道非开挖修复技术,但缺乏比较系统的施工控制与风险管理技术体系。针对该项技术的特点和实施要求,本文采用危害分析及关键控制点的方法,分析探讨了施工控制与风险管理技术体系。通过识别,原位固化法在城市排水管道非开挖技术实施过程中的潜在危害因素有37种,结合关键控制点的确定程序,分析得出了原位固化技术实施的准备阶段、衬入阶段、养护阶段、验收阶段、全程阶段等的关键控制点共计24个,最后对这些关键控制点进行危害结果、控制指标、关键限值、纠偏措施等方面的分析。更多还原

【Abstract】 Although trenchless rehabilitation with cured-in-place pipe(CIPP) is used in sewer rehabilitation in China,the technical system for the construction quality control and risk management is inadequate.Combined with CIPP characteristics and implementation requirements,hazard analysis and critical control point(HACCP) was used to set up the technical system of CIPP implementation.After analyzing,the 37 different potential risks were detected in CIPP implementation.Based on the procedures for determining critical control point(CCPs),the 24 CCPs were found in the preparation stage,the lining stage,the maintenance stage,the acceptance stage and the whole process.Meanwhile risk results,control index,critical control limits and corrective measures were summarized.更多还原
