Pipe Jacking under river/stream

Pipe Jacking under river/stream

Pipe Jacking under river/stream

(OP)
Hi,

I would like to know the min. requirements on pipe jacking under existing canal/river/stream.

Actually, I would like to know the min. clearance between natural alluvial stream bottom and jacking pipe crown.

Actually, stream width is 30m, its depth is about 1m and its bottom is natual alluvial(no riprap and lining exist).

I woulld like to thrust the pipe of 1000mm diameter.

Any experience on this matter would be helpful.

RE: Pipe Jacking under river/stream

You need to supply some more background information such as:

What product are you carrying in the new pipe?  
What would be the consequence of failure of that pipe?
What kind of pipe are you installing?  
Will it be in a casing?  
Do you have any data on the hydrology?  
How about soil conditions?
