移动模架现浇法在山区高铁桥梁施工中的应用

Application of Cast in Situ Casting of Movable Formwork in Construction of High-speed Railway Bridge in Mountain Area

我国铁路建设进入高峰期,尤其是西部地区的高速铁路或客运专线的修建受地形条件的限制,简支箱梁施工很难实现提前预制再专业设备架设的方式。根据实际情况,专门设计制作移动模架设施,在桥位处进行现浇制梁,有效克服了大吨位预制梁运输与架设的难题。

China＇s railway construction has entered the peak period, especially the construction of high - speed railw-ay or passenger dedicated line in the western region is limited by the terrain conditions. It is difficult for the construction of the simply supported box girder to advance the prefabrication and the erection of specialized equipment. According to the actual situation, the special design and manufacture of mobile formwork facilities, in the bridge site cast-in-place beam, effectively overcome the large tonnage prefabricated beam transportation and erection problems.
