Hiding rain drain pipe below the sidewalk

drainsidewalk

I have a 100mm pipe (4") that comes under the garage ramp and outputs the rain water to the street. My problem is that I couldn't have the pipe goes straight to the street because of the slope needed, so I diverted the pipe 45° at the sidewalk point.

The pipe end sits a bit above the curb level, so now I need to find a way to hide this pipe. I thought of maybe using a drain grate, but I couldn't find anyone with 45° corners (I could weld something, but I would be a very tedious work). Another idea is using a heat blower to compress the pipe to that it goes below the curb level, but I think this might create clogging problems.

Any other choices?

Why don't you move the end a little further uphill and empty the pipe into some kind of culvert drain or splash block that slopes down to the curb?

Or you could use a pipe fixture like this:

There's a brand name behind that thing (Mitered Drain), and I'm not sure there are identical alternatives, so I'll go ahead and identify the brand. I'm not their spokesman. They just have the solution that's identical to what came into my head when I saw your question.

Or maybe you could transition to a rectangular section of pipe:
