The invention discloses a method for leaking stoppage of a glass reinforced plastic pipe under pressure, and relates to the technical field of pipeline repair. Comprising the following steps: (1) polishing a leakage point into a circle; (2) leaking stoppage is conducted on leakage points through a rubber stick; and (3) the light-cured glass fiber reinforced plastic pipe prepreg tape is wound around the leaking stoppage position, curing reinforcement is completed under ultraviolet irradiation, and the light-cured glass fiber reinforced plastic pipe prepreg tape in the step (3) is prepared by compounding photosensitive resin and reinforced fibers. According to the method, the damaged pipeline can be repaired on line under the condition that production is not affected, leakage stoppage under pressure is achieved, and the method has the advantages of being short in repairing time, good in strength performance and short in curing time of the photocuring prepreg tape. 本发明公开了一种玻璃钢管带压堵漏的方法，涉及管道修复技术领域。包括以下步骤：(1)将泄露点打磨
