摘要：A method of lining a pipe comprises the steps of laying hose means along thebottom of a pipe to be lined, the hose means having been filled with a predeterminedquantity of settable lining composition, anchoring the hose means at each end along thebottom of the pipe, advancing a centrifugal lining machine along the length of the hosemeans, slitting the hose means in front of the advancing centrifugal lining machine topermit egress of the lining composition from the hose means, and delivering the admixedsettable composition to a centrifugal impellor of the centrifugal lining machine forapplication of the settable composition to the pipe wall as the centrifugal lining machineadvances along the pipe. The method is characterised by the step of guiding the slit andemptied hose means through an axial bore in the centrifugal lining machine to lie in aflattened condition on the bottom of the lined pipe wall rearwardly of the centrifugallining machine.
