对于路桥建设工程来说,混凝土施工是整个施工过程中最为关键的环节,同时也是难度最大的环节。因此,要想提高路桥工程的施工技术,混凝土施工技术就是关键。由于普通混凝土普遍存在弹性比较小、吸附性较差以及耐久性稍显欠佳等问题,因此针对混凝土的这些缺陷进行混凝土施工技术改进是非常具有现实意义的。文章从混凝土施工的准备工作、确定混凝土的配合比、混凝土模板的设计与安装以及混凝土的浇筑施工等几个方面分析了混凝土施工技术。 For road and bridge construction projects, concrete construction is the most critical part of the construction process, but also the most difficult part. Therefore, in order to improve the road and bridge construction technology, concrete construction technology is the key. Due to the common elasticity of common concrete is relatively small, poor adsorption and durability is slightly poor and other issues, so concrete defects in these concrete construction technology improvements is very practical. The article analyzes the concrete construction technology from several aspects such as the preparatory work of concrete construction, the determination of the mix proportion of concrete, the design and installation of concrete formwork and the pouring construction of concrete.
