How is concrete pump working in horizontally and vertically pumping?

For horizontally pumping, pipeline is easy to arrange.
For pumping concrete vertically, normally we leave some small holes and space each floor. When the building is finished, the holes and space will be sealed or left for some other function such as water transmission conduit. The steel pipe of our pump is through these holes and space in the buildings. Vertically pipeline via exterior and tied to the scaffold is also convenient.
