    • PURPOSE: A method is provided to decide the position of an opening in a branch pipe lining material and to prevent the branch pipe lining material from being short of intensity. CONSTITUTION: A branch pipe-lining unit is structured by inserting the body except for a color unit(3) and sticking the color unit between a setting head(8) formed in the opening of a pressure bag with a rubber. Then the branch pipe lining material forms a sealing space(S) by a branch pipe lining material(1). The inner diameter(d1) of the color unit is smaller than the inner diameter of the resin absorber after hardening and the outer diameter of a cylindrical unit(3b) is smaller than the inner diameter of the branch pipe opening. The height of the cylindrical unit is 0.5m/m to 50m/m. And the outer diameter of a flange unit(3a) is bigger than the inner diameter of the opening and the color unit keeps the shape by hardening the impregnated hardening resin.
    • 目的:提供一种确定支管衬里材料中的开口位置并防止支管衬里材料缺乏强度的方法。 构成:分支管衬单元通过将除了彩色单元(3)之外的主体插入并且将颜色单元粘贴在形成在压力袋的开口中的设置头(8)与橡胶之间而构成。 然后,支管衬里材料通过支管衬里材料(1)形成密封空间(S)。 彩色单元的内径(d1)比硬化后的树脂吸收体的内径小,圆筒形单元(3b)的外径小于分支管开口的内径。 圆柱形单元的高度为0.5m / m至50m / m。 并且凸缘单元(3a)的外径大于开口的内径,并且彩色单元通过硬化浸渍的硬化树脂来保持形状。
