MICROTUNNELLING

[Davide94]

Hello,

i'd like to know which normative or standard i may use to calculate the maximum force applied to the pipe during the jacking operation.

Thanks in advance

When you tell us what the anticipated geological conditions will be , then perhaps you can get answers

A bit less than it's allowable axial capacity which the vendor calculates for you ( at least for concrete pipe). Multiple jacking stations may be required for really long sections.

It's a calculation undertaken by the tunneling contractor in my experience.

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

Maybe I expressed myself in the wrong way. I want to know if there is a Standard, or
recognized and authoritative method, I can use to calculate the force applied to the pipe during the jacking operation (i.e : face resistance and lateral frictional resistance)

Thank you all in advance

which pipes : concrete ?

 

[Davide94]

Yes, it's a concrete pipe
