You'll probably never get rid of it entirely but there are a couple of ways you can try to get rid of it.

It all depends on time/money.

The most effective but expensive way is to spray it all with a herbicide and let it die off, then excavate out all of the effected soil to about a foot deep.
You'll have to then bring in fresh uncontaminated soil.

The other way is spray it then heavily much the whole area.

You'll probably get it coming back but it should be a bit more manageable.

I was gonna suggest a flame thrower

Turns out I may not of been wrong - have a look at this link.

Weak Points of couch Grass
1. Couch grass is shallow rooted, no long taper like roots going deep into the ground. The roots of couch grass typically go down about 10cm (4in) and rarely more than 15cm (6in).
2. If the soil is well-dug, the roots of couch grass can be pulled out with relative ease.
3. Digging of the soil weakens couch grass.
4. Couch grass produces less seed than most grasses

It does go on to say basically cut it down and then turn over the ground removing the (shallow) roots... It looks like using chemical meathods would save a lot of work though... I only googled because I didn't know what couch grass was.

looks as if i have been doing the right thing by digging,but it took about five hours to dig and sift the roots in about three foot of garden
Think i will try what both you and chadwickus suggests spray, then i will mulch
