因城际铁路施工,需接长京沪线下行K1440_(+500)K1440_(+771)既有桥涵。为确保既有京沪铁路行车安全,根据桥涵现场实际条件,采用D16m便梁预防性加固线路。由于不掏空线路,只是对线路的路基进行预防性加固。为此,特制定砼简易支墩便梁架设施工方案,确保提速区段桥梁设备和行车安全。
Due to the construction of the inter-city railway, it needs to take the long line of Beijing-Shanghai down K1440 _ (+500) K1440 _ (+771) existing bridges and culverts. In order to ensure the traffic safety of both the Beijing-Shanghai railway, the D16m free-standing beam is used to prevent reinforcement according to the actual conditions of the bridge and culvert.
