Try to evaluate the leaking of a grout in a soil
Try to evaluate the leaking of a grout in a soil
(OP)
Hello fellow geotechnicians!
I am about to install inclinometers in a soil made up of 3 layers : lime/sand/clay(from bottom to top), and I would like to evaluate the grout leak which is going to happen during the injection. Do you have any suggestion about a formula or a model I can use (I know the main geotechnical properties of this soil)?
Thank you very much for any idea!
Best regards

I don't have a sketch right now, but I can describe the project. It is a typical londonian soil :
Clay

Clay & sand

Limestone
I am installing inclinometers (nearly 100m depth) and I am trying to estimate the quantity of grout I must use.
The grout composition I am using is cement(94lb)/water(25 us gallons)/bentonite(39lb).
The borehole is 10cm wide, 100m deep, and the casing is 7cmm wide. For the moment, I am considering that the amount of grout leaking in the ground is nearly equal to the volume of the casing. It means I plan on a grout volume equal to:
0.0025 square m x pi x 100m = 785 L
I am sure there is some better way to evaluate this quantity, by calculating the volume of grout leaking in the ground.
I was thinking that maybe that Lugon test formulas could help me, but I didn't find anything useful...
Any idea?
