At present,the repair effect of municipal water supply and drainage pipe network inspection and repair work is general,and the repair time is long.To solve these problems,this study designed a trenchless detection and repair technology.Firstly,the state of the pipeline is preliminarily detected by video equipment,and the structural assessment of the pipeline state is completed according to the digital image.Then,according to the evaluation results,the defects in the current pipeline are divided,and the defect level is determined to construct and repair methods.Finally,the trenchless repair steps of the pipeline are set,the repair operation is completed,the target water supply and drainage network is selected,and the experimental link is constructed.The experimental results show that the application effect of this method is better,and the use of this method can promote the design and construction of the current municipal water supply and drainage network.
