Combining with the construction of the Royal Fushun ocean world overpass 110m double steel pipe concrete vault with basket type, the lift-up pump concrete construction and a quality control method of concrete are introduced. And according to the principles of concrete lift-up construction, lift-up pressure, some relative influence factors are analyzed and mix proportion of concrete is optimized; in addition, using the methods of setting non-return devices, exhaust overflow ori≥fice, etc. can solve the once lift-up problem of steel tube arch concrete.
