摘要
围滩水电站大坝坝体原设计采用浆砌石混凝土,但考虑到浆砌石混凝土技术要求高,施工速度慢,通过现场试验论证使用自密实堆石混凝土的可行性后,确定在大坝使用自密实堆石混凝土。自密实堆石混凝土是砌石体施工的新工艺,经过近半年来在围滩水电站大坝的应用表明,具有施工效率高、质量稳定等优点。
According to the original design of Weitan Hydroelectric Station,the masonry concrete is used to build dam.But considering that the technical requirements of masonry concrete are high and its construction speed is slow,and through field test,it is demonstrated that to use self-compacting concrete to fill rock-fill dam is feasible.Using this kind of concrete in Weitan Hydroelectric Station is selected.Placing this kind of concrete is a new technique for bonding dam.The application practice about half of a year indicates that this technique has many advantages such as high efficiency,stable quality and so on.
