1000 mm-cement pipe blocked by root invasion
How do I unblock a 1000-mm cement pipe used for agricultural irrigation that has been overrun by roots over a wide span of its length?

I would say you are looking at safety equipment and going inside the pipe with a sabre saw and then a cable to remove the roots once you have cut them out. Afterwards you will need fast-setting concrete to seal up any holes and prevent recurrence.
