Joint Assembly

Forsheda 116. Trelleborg

Step 1

Stretch the seal onto the spigot and position against the shoulder. Equalize the stress in the seal by lifting it at a few points. It is vital that the seal seats against the shoulder around the whole circumfe-rence of the manhole.

Step 2

Centre the manhole sections and complete the joint. Depending on the joint design it may be possible to joint one side of the manhole, followed by the other.
