Fix a broken sewer pipe in-situ

Anyone any tips for patching a broken sewer pipe in situ?

I was digging the garden over the weekend and managed to mangle a 6 foot section of the sewer pipe (4" wavin/plastic).

I cut the broken bit out and tried to fit a new full section in, but as both ends are fixed, it makes it very difficult. I was thinking of splitting the new section in the middle and try using a straight coupler and push both sections in using a downwards force at the same time.

Any tips welcome.

You need to buy two 4" repair (or slip) connectors. They are the same as standard connectors, but without the stops in the middle.
Remove the damaged section with clean straight cuts. Use a file to remove burrs and to put a taper on the outside of the pipe end. Cut a new section of pipe to fit snug into the gap. File and taper both ends.
Mark the pipes in the ground where the repair collar should stop at about halfway along the collar.
Using pipe lube, or washing up liquid, push the two collars as far as possible onto each end of the new section. Drop the new section into place and tap the collars up to the markers, half the repair collar on the old section and half on the new section. Flush lots of water down the line checking for leaks.
