消除清水混凝土基础表面气泡的研究

Study on the Bubble Elimination of the Surface of Pure Water Concrete Foundation

在传统的变电站、换流站施工建设中,外露基础在拆模后,基础表面存在大量的气泡,影响美观,在荆门换流站,通过对混凝土表面气泡的研究,全站清水混凝土施工工艺基础取得了很好效果,得到了国网公司领导高度认同。

In conventional construction of bare foundation,it is common that there is large amount of bubbles on the foundation surface when the module is removed,and it will impose bad effect on the appearance of the foundation.In the construction of 500 kV Jinmen HVDC converter station,the technique for the bubble elimination of the surface of dry concrete foundation was studied and was applied in the construction of foundation.It yielded a very satisfactory result.
