<p>The process comprises the step of entering a number of still not joined elongated panels (1), which panels at their long sides include organs for joining said panels, inside the manhole (5). The panels (1) are thereafter joined to form a cylinder (11) which is properly placed inside the manhole (5) or the pipe. The annular space between the wall of the manhole (5) or the pipe and the cylinder (11) is then filled with a curable material (12) such as concrete. The invention further comprises a supporting ring to be used in the process.</p> |
