确保桥梁预应力钢绞线张拉质量

To ensure that the bridge prestress quality Tension

结合实际工程的施工过程,从张拉的顺序及各种参数的计算、张拉设备、材料、张拉过程中的控制等方面分析影响桥梁预应力钢绞线张拉质量的各种原因,并对如何减少钢绞线的实际下料长度、钢绞线的直径、摩擦系数、钢绞线的纵横线的调整、张拉设备、波纹管的位置等影响钢绞线张拉质量的因素进行阐述。

In light of the actual process of construction, from the tension and the sequence of various parameters, the tension of equipment, materials, tension control of the process we analyze the impact of prestress bridge Tension quality of a variety of reasons, as well as how to reduce the actual Strand blanking length, the diameter Strand, Moldova rub coefficient, a lot more strands line adjustment, tensioning equipment the location of Bellows affect Strand Tension quality factors elaborate.
