(8)はワッシャを示している。In the figure, (1) is a suspension metal fitting of a tunnel bolt type rod, and the suspension metal fitting (1) penetrates the waterproof sheet (3) stretched over the segment (2) and anchors to the segment (2). To be done. The anchor ring construction is the same as before. A nonwoven fabric (4) is interposed between the segment (2) and the waterproof sheet (3). Reference numeral (5) is an insert plug embedded in the segment (2), and reference numeral (6) is a seal provided on the waterproof sheet (2) at a portion through which the hanging reinforcing bar metal fitting (1) penetrates. (7) is a tightening nut,
(8) shows a washer.
