Abstract:To solve the supervision problem of hidden construction process and difficult to visually judge quality in non-excavation repair projects of urban underground pipelines, this article builds a systematic supervision method system covering quality control in the construction preparation stage, in-situ solidification lining method construction process supervision, and repair quality inspection and acceptance based on a municipal drainage network renovation project. The proposed method was validated through engineering test data, and the results showed that the safety factor of the bearing capacity and the water tightness detection index of each pipe section met the regulatory requirements, verifying the engineering feasibility of the supervision method.
