Application of Cantilever Jumping Formwork in APC Shell Construction of a Third Generation Nuclear Power Plant
-
Abstract
The first phase of a nuclear power plant APC shell structure is made of reinforced concrete pouring, it can resist the impact of the plane, and protects the security of nuclear power plant factory. APC shell structure span is large, and having greater thickness of the wall with no horizontal and vertical support, thus the pouring of concrete quality requirement is strict. According to the APC shell structure quality requirements, the cantilever jumping formwork for concrete pouring construction is used and a construction technology of cantilever climbing formwork system is developed. By using this technique, it can ensure the pouring concrete quality and the surface flatness of the concrete wall of APC shell, and speeds up the construction progress of the wall and save a lot of manpower and resources at the same time. It has good economic and social benefits.
