Concrete temperature control in foundation restraint area at spillway section |
| |
| Abstract: | The spillway is one of the important structures for the Three Gorges project,with the highest blocks,bearing the max.water pressure,complex geometry and strict technical requirements.Due to various factors,the concrete in the foundation restraint area must be placed continuously in hot weather.The tough problem with the temperature control.over concreting in the foundation restraint area with higher placment rates and high volume,has been offset by a series of integrated measures proposed by the designer and the contractor,based on the quality and schedule requirements. |

| Keywords: | spillway section concrete in restraint area hot weather temperature control. |
