砼和预应力砼结构是桥梁工程主要结构形式,不论是上部结构(梁部)还是下部结构(墩、台和基础),砼数量都很大,一座大型桥梁往往需要灌注十几万甚至几十万m~3。砼施工已经成为桥梁施工中作业量最大,使用机械,人力和耗能最多,操作最繁重的作业。桥梁工程质量是否得到保证和砼施工各阶段质量控制有直接关系。因此如何正确选择和合理设置 Concrete and prestressed concrete structures are the main structural forms of bridge projects. Whether it is the upper structure (beam) or the lower structure (piers, platforms, and foundations), the number of plutonium is large, and a large bridge often requires more than 100,000 or even dozens of pours. Million m~3.砼 Construction has become the largest operation in the construction of bridges, with the use of machinery, manpower and energy consumption, and the most intensive operations. Whether or not the quality of the bridge project is guaranteed is directly related to the quality control at each stage of construction. So how to choose and set up properly
