The construction of steelreinforced concrete structure is complicated. The steel reinforcement and the steel structure connecting and intersecting construction are representative construction procedures. Using some special joint construction measures and technical measures in bedplate of CCTV new site project, engineers not only solve the construction difficulty successfully, but also improve the construction progress, which makes the construction of ultralarge and ultrathick bedplate successfully finished, and provides favorable condition for the construction of steelreinforced concrete structure of basement.
