摘要： A lateral pipe lining material comprises a tubular resin absorbing material impregnated with a setting resin, which has a flange at one end thereof and whose outer surface is coated with a highly airtight film. A sealing tube is detachably attached to the outer circumferential surface of the tubular resin absorbing material. The lateral pipe lining material is introduced inside a main pipe and its flange is brought into tight contact with the lateral pipe opening. The lateral pipe lining material including the sealing tube is then everted and inserted by fluid pressure inside a lateral pipe toward the ground level. After the setting resin is cured, the sealing tube is removed from the lateral pipe lining material. This enables the lining of a lateral pipe to always be performed reliably, regardless of the aboveground circumstances.
摘要翻译：侧管衬里材料包括浸渍有固化树脂的管状树脂吸收材料，其在其一端具有凸缘并且其外表面涂覆有高度气密的膜。密封管可拆卸地附接到管状树脂吸收材料的外周表面。侧管衬里材料被引入主管内，其凸缘与侧管开口紧密接触。然后将包括密封管的侧管衬套材料通过侧向管道内的流体压力插入地面。固化树脂固化后，将密封管从侧管衬里材料中取出。这使得侧管的衬里总是可靠地执行，而不管地上的情况如何。
