２ＯＰＪ画に止着する。#11 In the illustration, 1e2 is an adjacent large-diameter pipe with a diameter of 1200mm and a thickness of 2.3mm, and 3 is the joint of the seal pan. A sheet 4 made of butyl rubber is wrapped around the inside of the ζO-gate 30 and heated, and tubes 1 are attached to both sides of the center of the sheet 4.
It sticks to the 2OPJ picture.

...Fixed to the surface of tubes 1 and 2 from K. This band S has a small rib 7.7 and a large rib 8.8, which have an arcuate shape with an expanded section of 15cm and 4 degrees, on both sides and both ends of the central part, and has a large rib 8.8. As shown, the bolt 6 has a resin press-in port 9. The above special adhesive is in the form of a paste or putty containing epoxy resin as a component.
It becomes an elastic body after curing with l# surface adhesive.

ているので、大ａｏｔ。As mentioned above, according to the present invention 1jjk, all the large diameter oIFo seals are sealed from the inside, so the conventional Ill extraction work etc. can be done easily. In addition, by sealing against harmful birds, heat and construction time can be shortened, and costs can be significantly reduced. Since the resin is press-fitted and solidified between the shaped parts, the sheet presses into contact with the sealing part, and the sealing is performed reliably, and the band has a wave shape, so it is very effective.

According to the invention of claim 112, since the sheet is made of butyl rubber, the adhesion between the sheet and the large-diameter pipe is excellent, and the sealing process is reliable while preventing harmful birds. The ninth band 5 is also used to fix the tube 1.211C using a presser metal fitting 20 s 20 = Z t 20 that slides further. ,
