| Abstract: | The foundation type of Henan broadcast and TV tower is a pile raft foundation.The jointless construction technology of mass concrete is analyzed for its foundation slab has no post poured belt and concrete expansion and strengthened belt.It was introduced the jointless construction technology of the TV tower mass concrete.The results showed that temperature difference of two adjacent measuring points at the same position is less than 25 ℃.The technology controlled concrete crack effectively and provided construction experience for construction of similar projects. |
