<p>A method of lining a pipe comprises the steps of laying hose means along the bottom of a pipe to be lined, the hose means having been filled with a predetermined quantity of settable lining composition, anchoring the hose means at each end along the bottom of the pipe, advancing a centrifugal lining machine along the length of the hose means, slitting the hose means in front of the advancing centrifugal lining machine to permit egress of the lining composition from the hose means, and delivering the admixed settable composition to a centrifugal impellor of the centrifugal lining machine for application of the settable composition to the pipe wall as the centrifugal lining machine advances along the pipe. The method is characterised by the step of guiding the slit and emptied hose means through an axial bore in the centrifugal lining machine to lie in a flattened condition on the bottom of the lined pipe wall rearwardly of the centrifugal lining machine.</p> |
