Above ground, But buried

[CoCoE]

What do you call a pipeline with a soil hump, which is on grade level but covered with soil? I remember during my earlier years there was a hard sand packing on the soil. Can anyone help me out in this? What are these terminologies?

 

[TD2K]

Lots of the pipelines in Saudi Arabia were constructed like that. I thought there was a specific term but I can't remember it (it's driving me nuts). All I come up with are berms but I don't think that is correct.

I would go for surface bermed pipeline. If you do Assn image search on that term you get what I think you mean.

Sometimes it is called a rock berm,

There aren't many true surface laid lines which are buried this way. Most of the Saudi ones are actually buried, but they like to use Berms to locate the line and help reduce upheavel buckling.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Continuous Earthen Berm or

Saudi Aramco generally refers to these as "Continuous Berms". I've also seen "Continuous Crown".

The berm is composed of soil (sand) and rock excavated from the trench, with larger stones (preferably flat slabs) placed towards the outer surfaces of the berm making a kind of rock armor. The armoring helps to prevent loss of cover due to severe wind erosion of the fine sands that typically characterize their pipeline routes. Berms composed of sand alone, without armoring, placed in windy areas seldom last more than a few years.

For obvious reasons, do not use these in areas where surface water can be present.

The placement of the pipe might actually be below, or above the surrounding ground level.

BigInch, bimr, LittleInch, and TD2K , Thanks a lot for your reply !

Helped to make a me a report on the same. And thanks for BigInch for the pic, it differs a little in my case, but still that was fantastic !
