Has anyone had experience with stabilizing the area outside the directional drilled pipe. The normal drilling mud is documented as providing little to no support to the pipe. Therefore, it is hard to make ring deflection calculations work for normal pipe design. I was wondering if an...
I am designing a pipe for an HDD application, the driller is using a Bentonite mixture for his drilling mud. When I do the ring deflection calculation for the pipe what can I assume for supporting soil for the pipe.
The Directional Driller has told me that the mud gets very hard after a 24...

I have a situation where the existing stormwater disappears into a fractured rock bed in the side of a mountain and disappears. Locals have stated that there may be a cave underneath. Either way it is impossible to determine what its capacity is other than the fact that it has been working up...
