IMO the contractor Might be duct taping the couplings as they glue it together because they are not confident that the conduit will stay in place before the glue cures.
Sometimes the fit is poor enough that it still doesn't hold that well after the cement cures, sometimes the fit is so tight that a "dry fit" is hard to get back apart.
