摘要： A method for installing a liner in a large diameter pipeline. In accordance with the method, the interior surface of the pipeline to be repaired is prepared by removing excess debris and dirt. A repair composite is brought into the tunnel or pipeline in a dry state. Once the dry repair composite is laid out in the structure to be repaired the repair composite is folded out and saturated and wetted out with high pressure spray guns. The spray guns are employed within the structure and an appropriate resin material is applied as required to wet out the fiber material. A calibration bladder is inflated and holds the repair composite in place against the pipeline walls until the epoxy resin is fully cured. Once the process is complete, the bladder tube is retrieved out of the system leaving the repair composite as a stand-alone system.

摘要翻译： 一种用于在大直径管道中安装衬套的方法。 根据该方法，通过去除多余的碎屑和污垢来制备要修复的管道的内表面。 修复复合材料在干燥状态下进入隧道或管道。 一旦干式修复复合材料铺设在待修复的结构中，修复复合材料被折叠出来，用高压喷枪将其饱和并润湿。 在结构内使用喷枪，根据需要施加适当的树脂材料以润湿纤维材料。 校准气囊被充气并将修复复合材料保持在管道壁上的适当位置，直到环氧树脂完全固化。 一旦该过程完成，将膀胱管从系统中取出离开修复复合物作为独立系统。
