以后湾特大桥高墩施工的实例,在混凝土中使用复合外加剂和粉煤灰,实现了泵送混凝土在滑模施工中的应用。进而使得滑模施工在该标段得到了较为成功的应用,解决了地理位置险要、陡峭,施工场地狭小等施工困难。大大提高了高墩的施工速度、确保了混凝土的内在及外观质量、节省了成本。
After the construction of the bridge pier high pier example, the use of composite admixtures and fly ash in concrete, to achieve the pumping of concrete in sliding mode construction. In turn, sliding mode construction has been successfully applied in the bidding section, which has solved the construction difficulties such as danger of location, steepness and narrow construction site. Greatly increased the construction speed of high pier, to ensure the quality of the inherent and appearance of concrete, saving costs.
