Abstract:In the Yangtze River Protection of Yueyang, for different structural defects and degrees of pipe damage, such as wrong opening, fracture, deformation and leakage, through CCTV detection analysis, different trenchless repair construction techniques are adopted. The problem of excavation repair and single excavation repair is solved. Moreover, the construction period is short, the traffic pressure of urban excavation is small, and the quality and safety can be controlled.
