From the above, it is seen that there are many different demands for the pipe jacking slurry and drilling mud. Therefore, there are similarities and differences as well between inhibitory drilling mud and pipe jacking slurry. We can learn from the design idea of inhibitory drilling mud to design pipe jacking slurry in expansive soil.

Friction resistance is the main component of jacking force. Application of lubricant such as bentonite slurry in pipe jacking (that is, the so-called "slurry pipe jacking") is essential to reduce the friction resistance and therefore the jacking force [3, 4]. However, it does make it more complex for the calculation or prediction of ...
