混凝土箱梁顶推法施工工艺在沿海高速公路上跨京哈铁路立交桥施工中的应用

顶推法施工不需要大型的机械设备和大吨位的反力设施,施工过程中不影响桥下交通,顶推设备自动化程度高,循环周期短,施工进度快,安全系数高。因此,顶推法施工在跨线施工且有不断交要求的情况下具有很大的推广价值。

Application of Incremental Launching Method Construction Technique of Concrete Box Girder in Construction of Beijing Harbin Expressway Overpass on Coastal Expressway

Incremental launching method has no use for large mechanical equipment and largetonnage reaction equipment and it would not interrupt the traffic beneath bridge. It has such advantages as highly automatic incremental equipment,short recycling period,fast construction schedule,high safety coefficient. Therefore,incremental launching method is worth popularization under the circumances of overline construction without interrupting traffic.
