Disparities between regular precast and pipe jacking, Civil Engineering

Question

What are main disparities in design between regular precast concrete pipes and pipes used for pipe jacking?


Answer

For pipes used for pipe jacking, they have to possess follow sorts-

(i) Pipes must have high concrete force to withstand stress induced during jacking process.

(ii) There is firm tolerance in pipe measurement and pipe joints are specially designed to supply trouble-free joint information. Two usually accessible joints are rebated joint and butt end joint.

(iii) Pipes preferably have to contain smooth external concrete finishes to decrease friction between pipes and surrounding dirt.
