Pipes too much high rise

wtf how do you do that

(1) Make a gate with 3 levels of height using pipes. (2) Delete the horizontal parts at both ends. (3) Copy, raise 3 levels and paste. (4) Extend both ends to the ground. (5) Same as (2). (6) Build it and unify three sections of pipe. (7) Repeat from (3).

Holy cheese and rice!
