摘要
宣杭铁路复线崇贤特大桥采用164 m栓焊下承式钢桁架梁,跨越杭州市北绕城高速公路崇贤高架桥。钢桁架梁架设施工中采用在高架桥两侧用军用墩搭设两个临时支墩,同时利用高架桥桥梁中央分隔带70 cm的空隙,用8根[30槽钢搭设临时支墩,在不加前端导梁的情况下,进行反向拖拉,顺利完成了钢桁梁的架设施工。
1～4 m bolt welded steel girders were used in Chongxiante Bridge of the diphase lines of Huanhang railway, Which spans Chongxian Trestle over the circling - city highway in the north of Hangzhou. Two temporary piers were built on both sides of the trestle while the spanning and constructing of the steel girdles were done. Meanwhile 8 slotwares were used to construct the temporary piers in the space of 70 cm segmentation belt in the middle of the trestle. In the context of not adding front guide girdles, the steel girdles were pulled reversely. As a result, the spanning and construction of the steel girdles were finished successfully.
