    • A manhole liner and a method of using the same are provided. The manhole liner is sized substantially equally to the largest diameter of the manhole, so that the liner does not have to stretch to be pressed against the manhole wall. Additionally, the liner is impregnated with a resinous material capable of curing and hardening. A bladder, preferably stretchable circumferentially and having a diameter less than the smallest diameter of the manhole, is inserted into the liner. The bladder is expanded to press the liner against the wall of the manhole to dispense resinous material from the liner, while the liner is able to fold over itself in areas having a diameter less than the original diameter of the liner. Because the bladder stretches to produce a smooth outside surface, the resinous material will migrate to areas in the folds and will cure with a smooth interior surface.
    • 提供了一种人孔衬垫及其使用方法。 人孔衬垫的尺寸基本上等于人孔的最大直径,以使衬垫不必伸展以压靠人孔壁。 此外,衬里浸渍有能够固化和硬化的树脂材料。 优选将可沿圆周方向拉伸且直径小于人孔最小直径的囊插入衬里。 膨胀囊状物以将衬垫压在人孔的壁上以从衬里分配树脂材料,同时衬里能够在直径小于衬里原始直径的区域自身折叠。 由于膀胱伸展以产生光滑的外表面,树脂材料将迁移至褶皱区域并且将以光滑的内表面固化。
