This paper mainly tel s the story of steel tube arch concrete poured empowerments and rise construction techno-logy, and poured empowerments and rise construction is a top complicated process, whose key lies in the design of mix prop-ortion and concrete pumping, and whose difficulty is how to ensure the continuity of concrete pumping and the dense sex after pumping concrete; The self-compacting compensation shrinkage concrete can bet er solve the concrete pumping cont-inuity and dense sex.
