With the traditional method of repairing the damage of underground sewer pipelines, extravasation is sometimes high. In order to solve this problem, a new method of repairing the damage of sewer pipelines is proposed based on virtual reality technology where the map method is used to position the damage location and damage degree of sewer pipelines, and then the communication simulator transmits the damage signal of sewer pipelines to the computer to output the damage identification of sewer pipelines. Virtual simulation technology is adopted to provide proper adhesive repair in regard to the different damage levels of sewer pipelines. The results show that compared with the traditional repair methods, the sewer pipeline damage adhesive repair material based on virtual reality technologyis more reasonable. After repair, special reagents are used for cleaning to improve the adhesive repair effect of the damage sewer pipeline and reduce extravasation of the adhesive repair of damaged sewer pipelines.
