HSR precast single wire box girder
With the socioeconomic development and the national "One Belt And One Road" initiative, high-speed railway as an efficient mode of transportation has been rapidly developed in recent years. In the construction process, precast box girders are often assembled into lines on site. The application of box girder can ensure the stability of railway lines and control the slope of railway lines.At the same time, compares to road construction, this method eliminates the potential safety hazard caused by subgrade settlement.At present, there are two kinds of common size 24&32 meters. Among them, single line box girder is mainly used for ramps and other specified sections.The precast single wire box girder produced by our factory has been applied in many domestic high-speed railway construction projects and won wide praise.For the raw materials, we use steel plate that produced by large state-owned steel factories like Wuhan Iron and Steel (Group) Corp,Handan Iron and Steel Group, to ensure the reliable quality of finished products .In terms of production technology, our factory keeps putting on high-precision equipment, such as plasma cutting machine, welding robot, etc., to ensure that the templates we produced do not have the problems like grout leakage, formwork shifting in the process of usage, to ensure that the beam body is beautifully formed and balanced.At the same time, we also learn from the problems of customer feedback in actual use, optimize design and construction, and continuously improve and strive for perfection.
