水泥混凝土集中拌和在高速公路施工中的应用

The Application of Concrete Concentration Mixing to Expressway Construction

在高速公路的建设中，构造物(桥梁、隧道、通道和涵洞等)的建造始终居于十分重要的地位，其建造质量和进度往往会对整个工程的建设产生重大的影响。水泥混凝土是修建各种构造物的主要建筑材料，因此水泥混凝土的生产工艺流程直接影响整个工程的施工进度与质量。

The Application of Concrete Concentration Mixing to Expressway Construction In the building of expressway,the erection of structures(bridges,tunnels and culverts,etc.)always occupies very important position),because their quality and progress exert often a tremendous influence on the construction of whole Projects.Concrete is a key materlal to build various structures,therefore its Process has directly an effect upon the Pace and quality of entire engineering.In the article,the reasonable arrangement of concrete production points in expressway building.and the construction process of concrete and the rational matching of construction machinery are discussed in terms of the expressway YJ-CS ll sectlon project along the Changjiang River at Runyang City.
