kevind +1, I don't think you would like the results of the sewer backing up through that setup. If you get a plug outside everything from above will come out of that pipe and onto your floor. That is a disaster waiting to happen.
I would install a sewage pit with a pump for the washing machine. Then plumb the discharge above and vent as necessary. You need a plumber.
